HORTICULTURE Promotion of horticulture can, not only lead to livelihood security and higher economic returns but also nutritional security. The region is ideally suited for arid and sub-tropical horticulture. Even tuber crops could fit the crop rotation and lead to higher yield and income. In order to help farmers to go for horticulture, the university has laid stress on fruit crops like guava, mango, aonla, pomegranate etc. In RCA, Voluntary Centre of AICRP on Vegetables has been opened. Floriculture unit has been strengthened. Post harvest technology unit also is going to be expanded looking into the relevance and demand for the region. Establishment of Hi-tech Horticulture Unit will go a long way in promoting horticulture in the region. Technologies will be developed, high quality planting material generated and training provided to farmers and rural youth so that this activity is taken up in a big way.

Fruits Guava (Psidium guajava) •

Guava is one of the important fruit grown in south and south eastern part of Rajasthan. The varieties grown in this region are low yielding with poor quality. Therefore to select suitable variety studies were undertaken. In this performance of eleven different guava cultivars have been evaluated. Among the cultivars, L-49 (Sardar) exhibited highly vigorous vegetative growth as well as produced maximum fruit yield (54.6 kg/ plant), highest fruit length (6.8 cm), width (6.7 cm) and TSS (11.8oBrix) as against lowest fruit yield in Allahabad Safeda (34.5 kg/plant).



There are three distinct flowering periods i.e. Ambe Bahar, Mrig Bahar and Haste Bahar results flowering and fruiting throughout the year with poor fruit quality and yield. Therefore, experiments were carried out to avoid heavy crop load during rainy season crop (Ambe Bahar). Results revealed that the treatment of 10% fertilizer grade urea foliar spray at 50% bloom stage in month of May was the best giving highest fruit yield of (58.8 kg/plant) as against 34 kg/plant in control.



To study the comparative performance of different methods of planting and plant population per unit area an experiment was conducted on L-49 guava planted under five high density planting systems viz., Square, Single Hedge row, Double hedgerow, paired planting and Cluster planting system. The results of the study revealed that highest fruit yield of guava was recorded in double hedge row system (105.3q/ha) and minimum in square system (64.9 q/ha).

With a view to find out the optimum fertilizer level for guava experiment was conducted at ARS, Udaipur. It was found that the maximum fruit yield per plant (72.3kg /plant) was recorded with 60g N, 50gP &100g per tree and minimum in control (40.4 kg per plant).

Promising Cultivars MPUAT S-1 An apple colour red skin variety developed with medium tree stature i.e. height about

2 m and plant spread

1.46m EW and 1.39m NS,. average fruit weight 125 g with fruit length 4.8 cm and width 4.7 cm, yield about 30 kg per tree from 5 year old tree having 14 per cent TSS with low and soft seeded character. This variety was identified for release in 17th group meeting of AICRP on Sub-Tropical Fruits held at Udaipur during 2-4 June, 2006.

MPUAT S-1

MPUAT S-2 This is greenish yellow coloured fruit skin variety with 3m tree height average fruit weight 200 g with fruit length 5.25 cm and width 5.50 cm and per tree average yield 50 kg from 5 year old tree with 12.5 per cent TSS. This variety was identified for release in 17th group meeting of AICRP on Sub-Tropical Fruits held at Udaipur during 2-4 June, 2006. MPUAT S-2



With a view to get higher yield of guava and to make best use of resources, an experiment was carried out at RCA, Udaipur during the year 2006 to select a variety suitable for ultra high density planting (Meadow orcharding). In the experiment four cultivars namely MPUAT S-2, L-49, Lalit and Sweta were planted at 1 m x 2 m spacing. Plant canopy was managed by pruning twice in a year (February and September). On the basis of one year experimentation it was found that under UHDP system upright growth habit varieties (L-49, Lalit & MPUAT S-2) were found more suitable over spreading (Sweta). In addition to this, under UHDP system guava plant showed precocious and prolific bearing habit enormously.

Meadow orcharding in guava Orange Fruits

‰

A survey cum laboratory study was carried out during 2001-2003 to assess nutritional deficiency in mandarin orange orchards of Jhalawar district. The results of investigation showed that soils were silty clay to clay in texture, slightly alkaline in reaction, calcareous having low to medium organic carbon, medium nitrogen and phosphorus and high potassium. The available micronutrients were adequate except iron. But the iron and zinc content in mandarin leaf was in deficient category.

Mango and Aonla The poor survival of fruit plants has always been a problem in tribal area. Therefore, four low cost micro irrigation systems i.e. pitcher, bottle drip, hollow plastic tube and bucket with drip were on mango and aonla plants at ARS, Banswara and 15 villages of GVT project area. The main aim of the project was to improve the initial establishment of plants (survival) in the period of acute shortage of water. The improved survival percentage (50-65% in mango and 60-80% in aonla) was achieved besides the saving of water up to 48% by employing improved methods as compared to traditional flood irrigation system. Taking the overall cost, performance and adaptability of system, farmers preferred pitcher irrigation system followed by bucket with drip and bottle drip system.

Soft wood grafting in mango An experiment was conducted during two consecutive years i.e. 2005-06 and 2006-07 on performance of soft wood grafting in different mango varieties under Udaipur conditions. For this one year old root stock (Deshi) and same diameter scion (improved variety) of respective varieties were grafted in month of August. The scion success in poly bags was periodically recorded. It was concluded that the maximum per cent graft success of 80% was found in Kesar followed by Mallika (75%), Langra (75%), Dashehari (70%), Amrapali (70%), Alphanso (60%) and minimum in Himsagar (55%).

Two years field studies conducted with variety Badshah at ARS, Kota showed that planting of potato at 60 cm x 10 cm spacing and fertilizer application N, P2O5 and K2O at 150, 120 and 100 kg/ha followed by haulm cutting at 80 days after planting produced highest number of seed size tubers (371/sqm) as well as total tuber yield (75.4 q/ha) as against 302 /sqm (seed size tubers) and 62.4 q/ha, respectively in control (spacing 60 cm X 20 cm, fertilizer N, P2O5 & K2O at 150, 120 & 100 kg/ha). An experiment was conducted at ARS, Kota for two consecutive years during 2005-06 & 2006-07 to study the application of nitrogen through fertigation, and saving of water under drip irrigation in potato variety K. Badashah. The drip irrigation at 75% PE + 100% N through fertigation proved best treatment and recorded 37 % saving in irrigation water over the treatment surface irrigation and entire NPK as soil application. The tuber yield was at par in both the treatments. An experiment was conducted for two consecutive years (2005-06 & 2006-07) to study the effect of bio-agents and chemicals against black scurf disease of potato. Minimum disease incidence, disease index and maximum yield were observed when tubers were treated with boric acid alone followed by boric acid + B. subtilis. The boric acid treatment recorded 43 per cent less disease incidence and 31 per cent higher tuber yield as compared to control.

Sweet Potato (Ipomea batatas) ‰

An experiment was conducted at ARS, Banswara during the year 1998 and 2000 to workout the optimum dose of N and K nutrients for sweet potato. Results revealed that application of N at 90 kg/ha gave the maximum tuber yield of sweet potato (133.5 q/ha) as against 72.9 q/ha in 45 kg N + 30 kg K2O /ha treatments.

‰

The field trial conducted for two consecutive years (2000 & 2001) at ARS, Banswara to assess the effective weed control system in sweet potato indicated that application of preemergence pendimethalin at 1.5 kg/ha was highly effective in controlling mixed flora of weeds in sweet potato with weed control efficiency of 73.7 per cent closely followed by its lower dose of 1.0 kg/ha (70%). Pre plant soil incorporation of fluchloralin at 1.0 kg/ha and preemergence alachlor (G) at 2.0 kg/ha were also found promising.

Tomato (Lycopersicum esculentum) ‰

Six releases of Trichogramma chilonis at 1.5 lacs/ha at interval of 10 days from 30 days after transplantation proved most effective against the fruit borer (Heliothis armigera) in tomato where only 15 per cent fruit damage was observed as against 39 per cent in control. Highest fruit yield was also recorded under this treatment. NPV-H spray stood next in order but was equal to endosulfan 35 EC at 1.0 l/ha (standard check). Fruit borer infected

‰

In tomato two sprays of organametallic copper and two sprays of amino acid copper minimized the blight infection by 20.2 and 23.0 per cent, respectively as against 61.2 per cent in control. The corresponding yields obtained were 157.8 and 134.7 q/ha, respectively.

‰

An experiment was conducted at ARS, Udaipur during the year 2006 and 2007 with the objective to find out the effectiveness of ready mixture of flubendiamide against insect pests of tomato. The results revealed that three sprays of flubendiamide 24% + thiacloprid 24% 48 SC at 200 ml/ha at 15 days interval, initiating first spray at peak flowering stage was most effective in reducing fruit borer, H. armigera and sucking insect pests viz; jassids, white fly, aphids and thrips. It also gave the highest mean marketable fruit yield of 257 and 255 q/ha against 116 q/ha in control.

Brinjal/ Tomato/ Chilli ‰

Root-knot nematode, Meloidogyne incognita is a polyphagous nematode attacks on variety of crops including vegetables. The nematode is responsible for heavy losses in light and medium textured soil on tomato, brinjal and chilli. Therefore, trials were carried out during four consecutive years (2000-2003) on farmers’ field near Udaipur (Bujada, Lakhawali, Behuti and Eklingpura) to

acquaint farmers about nematode menace and their management. Solarization of nursery beds treated with carbofuran at 0.3 g a.i. per sq.m. followed by neem cake at 5 q/ha as organic amendment was adopted for management of root-knot nematode, Meloidogyne incognita on tomato, brinjal and chilli. Experimental findings revealed that nematode management technology resulted into net profit of Rs 3313, 3782 and 3725 per hectare with C: B ratio of 1:2.09, 1:2.25 and 1:2.23 from brinjal, tomato and chilli, respectively.

Chilli (Capsicum annuum) ‰

Soil application of Trichoderma spp. caused enhanced accumulation of the phytoalexin capsidiol in roots of four chilli cultivars in quantities sufficient to inhibit growth of R. solani in vitro. Chitinase and β-1, 3- glucanase activities were enhanced as well. These results suggest that in addition to antogonism Trichoderma spp. suppressed R. solani incited chilli root rot through phytoalexin synthesis and systemic acquired resistance. The changes in another pathogenesis related enzyme peroxidase were not consistent with the level of protection. Soil application of Trichoderma spp. resulted in increase in the superoxide

radical

and hydrogen peroxide

generation. There was increase in the reactive oxygen species (ROS) scavenging enzyme catalase.

Cabbage (Brassica oleracea var. capitata) ‰

In cabbage minimum black rot infection of 20.9 per cent was observed with streptocycline followed by 24.0 per cent in garlic bulb extract as against 68.0 per cent in control. The highest yield of cabbage (126.96 q/ha) was also obtained in streptocycline followed by garlic bulb extract (118.49 q/ha). The highest net profit was obtained in streptocycline (Rs. 38179) with B:C ratio of 3.81.

‰

An experiment was conducted at ARS, Udaipur during 2006 and 2007 with the objective to find out the effective dose of fipronil for the control of thrips. The results revealed that three sprays of fipronil 80 WG at 62.5 g/ha caused highest reduction of thrips in chillies and also yielded the highest mean fresh marketable fruit yield of 145.9 q/ha as against 87.3 q/ha in control.

Cauliflower The experiments were taken under field conditions for two consecutive years i.e., 2003-04 and 2004-05 for management of Spodoptera litura (Fab.) on cauliflower under organic and modern farming. In this research different IPM modules consisting of three different components were evaluated. Under organic farming the module consisting of cow urine + neem leaf extract/Sl NPV (250 LE ha-1) /Sl NPV (250 LE ha-1) was found most effective with maximum percentage reduction in larval population during both the years of experimentation, with maximum mean yield (170.50 q ha-1) and maximum increase in yield (57.75 q ha-1) over control. Under organic farming the

maximum benefit was recorded from this module with cost benefit ratio of 1:5.35. Whereas, under modern farming the module consisting of dimilin (200 g ha-1)/ cartap hydrochloride (600 g ha-1)/ Lambda cyhalothrin (400 ml ha-1) was found most effective in reducing larval population of S. litura, with maximum yield (mean 181.30 q ha-1) and maximum increase in yield over control (68.55 q ha-1). From this module maximum profit was recorded with a cost benefit ratio of 1:11.54. Hence, on the basis of this research for organic farming cow urine and fermented whey with neem and dhatura leaf extracts can be recommended for the management of initial pest population, whereas in case of severe infestation biopesticides like SlNPV and Btk. should be applied. Lambda cyhalothrin at 400 ml/ha, cartep hydrochloride at 600 g/ha and dimilin at 200 g/ha can be recommended for modern farming for the ecosafe management of S. litura.

The result revealed that the root yield ashwagandha was increased with increase in irrigation levels and a maximum of 9.1 q/ha was recorded in irrigation level of cumulative Pan Evaporation (CPE) of 500 mm as against 4.8 q/ha in no irrigation treatment. Further the root yield was also increased by nitrogen application upto 30 kg /ha by 29.3 per cent over no nitrogen (6.4 q/ha) and thereafter it declined.

‰

Experiment conducted to evaluate response of Asgandh to various plant growth regulators at RCA, Udaipur during 2002-03 and 2003-04 revealed that two sprays of mepiquat chloride at 1000 ppm (at flower initiation stage and 15 days after first spray) significantly increased main root length, main root diameter and dry root yield by 46.1, 16.5 and 39.9 percent, respectively as compared to control. Quality of roots, when judged in terms of total alkaloid content, alkaloid yield, water soluble sugar content, alpha amylase activity and total phenol content was improved significantly by two sprays of mepiquat chloride 1000 ppm, closely followed by two sprays of chlormequat chloride 250 ppm.

Safed Musli (Chlorophytum borivilianum) ‰

For planting of safed musli the optimum weight of roots should range between 2 to 6 g. Separation of fleshy roots in the month of April reduced damage of tubers in comparison to February and March. The paired tubers gave more percentage of sprouting and less damage of tubers in storage when compared to individual tubers.

‰

The fleshy root yield of safed musli increased with increasing plant population and maximum of 7.9 q/ha mean yield was recorded in 3.3 lakh/ha plant population treatment as against 5.8 q/ha in 1.7 lakh/ha. Safed musli responded significantly to FYM application upto 30 t/ha which increased the fleshy root yield by 32.9 per cent over no FYM.

‰

In order to identify appropriate method of planting safed musli, an experiment comprising four planting methods i.e. flat beds, ridges, furrows and raised beds was conducted during 2002-03 and 2003-04 at RCA, Udaipur. Results revealed that planting of safed musli on the top of ridges (7” high) at 30 x 15 cm spacing was appropriate method for planting this crop, as the values of roots / plant (9.9) length of roots (8.5 cm), diameter of roots (0.47 cm), fleshy root yield (17.8 q/ha) and sapogenin yield (2.9 kg/ha) were highest in this treatment. The lowest values of all these parameters except roots/ plant were observed in raised beds.

In order to select suitable chemical to control chlorosis and increase productivity and quality of safed musli, an experiment comprising 10 chemical treatments was conducted during 2001-02 to 2003-04 at Udaipur. Results revealed that elemental sulphur at 150 kg/ha applied in soil before 15 days planting significantly increased various growth parameters, chlorophyll content of leaves, fasciculated roots yield, sapogenin content, sapogenin yield and net returns compared to other chemicals. Next in order was two foliar sprays of FeSO4 (0.5%) at 20 and 40 DAS.

Isabgol (Plantago ovata Forsk) ‰

Application of three irrigations at 25, 50 and 75 DAS significantly increased the seed yield of isabgol compared to two irrigation schedules. Response of applied N was observed upto 30 kg/ha. The swelling factor of seeds decreased by increased irrigation and nitrogen levels.

‰

Application of 40 kg N + 20 kg P2O5 /ha produced significantly higher seed yield and psoralen content of psorelea (babchi). Further a spacing of 40 cm x 30 cm was found most appropriate for its cultivation.

‰

With a view to find out control measure for downy mildew in isabgol, experiments were carried out for three consecutive years from 2002-03 to 2004-05. It was found that there was less incidence of downy mildew in the crop sown up to 20th November. The difference was up to 46 % less disease in early sowings dates (25th October, 1st November, 10th November and 20th November) as compared to late sowing dates (30th November and 10th December). The seed yield and swelling factor a measure of quality was also more in the crop which was sown up to 20th November The average of three years of the yield obtained in the plots with 20th November sowing was 16.6 q/ha as against the yield of 9.5 q/ha in 10th December sowing date.

Opium poppy Opium poppy is an important Rabi crop of zone IVa, however, it suffers from downy mildew every year in varying degrees. Experiments were carried out for three years on different dates of sowing, seed treatment and foliar sprays to manage this disease. It was found that crop escaped (to some extent) downy mildew when sowing was done from 25th Oct-1st Nov. during the year study. Disease incidence was observed up to 21.3 % in the crop sown between 25th October to 1st November, whereas in the sowings done after 8th November, the disease incidence was up to 36 %. Seed treatment with apron 35SD at 8g/kg seed with foliar spray of metalaxyl at 0.2 % at 35, 55 and 75 DAS reduced the downy mildew infestation up to 50% and thereby increasing the seed, husk and latex yield as well as higher morphine content.

Potato Crop Weather Relationship An experiment on potato was conducted at ARS, Kota with the objective to study the effect of planting dates in prevailing varieties in view of the climatic change. Four varieties of potato, K. Badshah, K. Bahar K. Ashoka, & K. Pukhraj were planted on five dates i.e. 10 Oct., 20 Oct., 30 Oct., 12 Nov. & 30 Nov. in two consecutive seasons (2007-08 & 2008-09). Results indicated that the total tuber yield was maximum when varieties were planted in normal date of planting i.e. 30 Oct., & 12 Nov. The deviation of 10-20 days in planting date did not affect yield significantly. The return was maximum (40025.38 Rs./ha) with variety K. Pukhraj when planted on 12th November.

Intercropping (potato + mustard/methi) With the objective to identify most remunerative intercrop in potato, an experiment was laid out at ARS, Kota during 2007-08 & 2008-09 taking mustard & methi as intercrops. The results revealed that potato equivalent yield (t/ha) and net return respectively were maximum (24.725 t/ha and 76663 Rs/ha) when three rows of Potato+ two rows of Methi was intercropped followed by sole potato with 100% RDF where yield and net return were 24.046 t/ha and 61563 Rs/ha respectively.

Water Management Onion An experiment was conducted for two years (2008 & 2009) to find out the effect of micro sprinkler and fertigation on the bulb yield (26.36 t/ha) of onion. Mean data indicate that maximum bulb yield was obtained when irrigation was applied at 100% of PE along with application of 100% nitrogen through fertigation. From water saving point of view irrigation at 60% of PE + application of 100% nitrogen through fertigation was found best. By applying this treatment 818.56 kg/ha/cm water use efficiency and 48.44% saving of water was obtained.
