This Rajasthan Agricultural Research Institute (RARI) is a constituent research station under Shri Karan Narendra Agricultural University (SKNAU), Jobner (Jaipur-Rajasthan). It is situated at 390 meter above mean sea level on latitude 26.50°N and longitude 75.47°E. Since its inception in 1943 it has come a long way, overcoming an era of national food deficits to that of self-sufficiency with a surplus food-grains reserve. This research station was initially under the control of the state Govt., which in April 1977 transferred it along with the responsibilities of crop research to the Udaipur University, a multi-faculty university. Later, in 1987, the first Agricultural University in the state was established with its main campus at Bikaner and this research station thus came under the jurisdiction of the Agricultural University, known as the Swami Keshwanand Rajasthan Agricultural University. Since Govt. of Rajasthan has established new Agricultural University at Jobner, in September 2013 named as Shri Karn Narendra Agricultural University (SKNAU), Jobner (Jaipur-Rajasthan). The Director is the In-Charge of the research institute and is responsible to the Director Research, SKRAU, Bikaner. Three Agricultural Research Sub Stations (Diggi, Tabiji and Kotputli) come under the administrative jurisdiction of this institute, where as four KVKs (Ajmer, Banasthali, Dausa and Chomu) get technical information from this station for disseminating the same to the farmers.

The valuable contributions made by the agricultural scientists of this pioneer research station have helped the Nation in maintaining the balance between its population growth and agricultural production. In order to increase productivity, improve quality and profitability not standing with the population pressures, rigorous efforts are still on the way at this centre and the scientists are poised to achieve these goals. Being foremost in advancement of agricultural research activities in the state, today, this research centre is a pride of Rajasthan.

Onion: Varieties developed – 3

Onion is one of the most important commercial vegetable crops grown in Rajasthan. It occupies about 25 -30% area of the total vegetable crops in the state. It is predominantly a rabi season crop but in kharif season it accounts for about 10 -15% of the total production. The onion varieties RO-1 (copper red bulb, 2004) and RO-59 (red bulb, 2005) are the first released varieties of Rajasthan developed by this station. Recently, RO-252 (red bulb, 2011) variety has also been developed and released for cultivation in Rajasthan. Both RO 59 and RO 252 were also found suitable for kharif season.

Seed production programme

This Station is the largest producer of the nucleus and breeder seed in the State.

The best quality planting material of improved varieties of wheat, barley, chickpea, mungbean, groundnut, clusterbean, cowpea and onion is produced by the Scientists of this Station.

Truthful level seed (TFL) of improved new varieties of 8 diverse crops is produced and made available to the farmers by this Research Station.

Strengthening of nucleus & breeder seed production programme of improved varieties at this station has resulted in enhancing the Seed Replacement Rate (SRR) of different crops in the state.

Technology development

It is important to improve the efficiency of all production inputs, e.g., seed, water and nutrients to achieve sustainable increase in crop productivity and minimize the losses caused by pests, weeds and during post-harvest handling. A large number of agro-techniques have been developed and recommended time to time, which have significantly contributed to the increase in production and productivity in the state. In the last 10 years more than 220 technologies have been developed for maximizing the production and productivity in the state. Some of the important aspects addressed are-

Crop culture management

Fertility improvement

Productivity enhancement through bio-regulators

Integrated nutrient management

Micro-nutrient management

Organic crop production

Weed management

Eco-friendly economic crop sequences


Judicious water use

Integrated diseases and pest management

Post-harvest management

Seed storage management

Varietal characterization

Farm mechanization

Pesticide residue management




Agro-technologies: Advance planting (first fortnight of June) in Groundnut; crop geometry in HPS groundnut (30x15 cm), onion seed production (45x30 cm), radish seed production (75x30 cm spacing of stacklings) and isabgol (line sowing at 30 cm distance); fertilizer doses in pearl millet (15 kg P/ha with PSB), groundnut (15 kg N + 30 kg P2O5/ha) and tomato (180 kg N + 120 kg P2O5 + 80 kg K2O/ha).

Bio-regulators: Grain yield has been increased by 10-15% through spray with thiourea @ 0.05% in wheat, mustard and chickpea and @ 0.1% in pearl millet (moisture stressed conditions).

Cropping sequence:  Clusterbean- rabi onion - groundnut - wheat have been found most remunerative cropping sequence and at the same time, maintaining the soil health.

Weed Management: Weeds are the unwanted competitors for nutrients and thus reduce the crop growth and production. To minimise such losses and control the weeds, recommendations have been given like pre-sowing application of isoproturon (0.75 kg/ha) + 2-4, D (0.4 kg/ha) in wheat (to control Rumex), fluchloralin/pendimethalin @ 1.0 kg a. i./ha + one hand weeding in mungbean, onion (at 50 DAT), sesame, groundnut, etc.

Sulphur Management: Sulphur deficiency was identified as a major problem. Recommendations were given for its use in deficient areas through gypsum – a natural resource available in plenty in Rajasthan in different crops like chickpea, mustard, groundnut (250 kg/ha), sesame (150 kg/ha), fenugreek (80 kg/ha), garlic (400 kg/ha).

Micro-nutrient Management: Plenty of work has been done on nutrient management for recovering the losses due to specific mineral deficiencies. Under brackish water irrigation zinc availability is limited and hence it was recommended to use 25 kg/ha ZnSO4 in such soils (EC 2.1 dsm-1, pH 8.8, RSC 14.0 meq l-1 ) in case of mustard. Under general zinc deficient soils also the use of ZnSO4 @ 25 kg/ha has been recommended in Wheat, Mustard, Pearl-millet, Fenugreek, Sesame, Cauliflower, Marigold, Chickpea, Groundnut, Cowpea, and Onion. Likewise, recommendations have been given for deficiencies of manganese, molybdenum, copper and boron in different crops.

Organic Farming

A methodology was recommended for preparing good vermi-compost. Mixing 100 kg mustard straw with 25 kg fresh dung and 12.5 kg sand followed by moistening up to 3% level and adding few earthworms and finally stirring well up to 90-95 days at 30 days interval resulted into formation of good manure with CN ratio 20:1. This has been recommended as an organic fertilizer to be used @ 2.5-10.0 t/ha depending on the crop like wheat, barley, chickpea, pearl millet, coriander, onion for reducing the use of chemical fertilizer by 25 to 50%. The technique has been disseminated to farmers and is widely accepted.

Use of naturally occurring high grade phosphate rock (HGPR) after vermi-composting and with phosphate solubilizing bacteria (PSB) has been recommended as a better source of phosphate fertilizer (PROM) in wheat, barley, chickpea, and groundnut.

As a measure to use farm waste, mustard straw was found to be the best substrate followed by sorghum straw for cultivation of mushroom (Pleurotus citronipilatus).

Protection Technologies

Technologies have been developed for control of termites in wheat, pod borer in chickpea, white rust in mustard, wilt in cumin and tinda, stem rot in chillies, powdery mildew in rose, rust in aonla. To protect crop from heavy losses due to diseases and pests in different crops, certain chemical and bio-controls have been recently recommended, like -

Pesticide Residue:

Onion Storage:

Seed Storage

Onion Storage: Two tier bamboo made structures with about 25q storage capacity have been designed for safe storage of onion bulbs.

Efficient Water Use:

Farm Mechanization

Bio-Molecular Technique:

Drought Tolerance Characterization:


The varieties and the technologies developed at this research station are economically viable, socially acceptable and ecologically sustainable. On-farm trials have shown that adoption of production and protection technologies along with the high yielding varieties give 25-30 per cent increase in production as compared to the farmer's practice. The estimates show that the average food grain production has increased from 109.20 lakh tonnes in 1991-2000 to 130.75 lakh tonnes in 2001-2010 and average oilseed production from 29.96 lakh tonnes in 1991-2000 to 41.88 lakh tonnes in 2009-2010. The increased production accounts for a benefit of about Rs. 2155 crores in food grain and Rs. 1788 crores in oilseeds in which this station has the major contribution in terms of varietal and technology development. Hence, adoption of the improved technologies is helping the state in uplifting the economic status of the farmers. The in exhaustive research efforts in pulses have earned an award for the state being first in pulse production in the country.


Dissemination of Newer Technologies at Village Level:

Newly developed high yielding and disease resistant varieties of different crops and the improved technologies generated by the scientists of RARI Durgapura, Jaipur are demonstrated through FLD’s at Farmers Fields every year to aware the farmers for enhancement of productivity. Also the farmers are regularly educated through farmer’s Fair, Kisan Gosthii & Training Programmes at village level. I recent years the state agriculture department has also provided funds under RKVY for promotion of improved technologies at village level for promotion of improved technologies at village level in kharif and rabi seasons. All the efforts made in this endeavour are positively contributing for improving socio-economic status of farmers in Rajasthan.

A unique programme on “Action Research for refinement of Package of Practices for productivity enhancement of crops in different Agro-Ecological Situations (AES) was undertaken were 668 experiments were conducted on varietal evaluation, various production and protection aspects covering about 267 ha area (2009-11). Total 8 farmers fair/field days were organized involving participation of 3836 farmers in the programme.
