About ARS, Navgaon

Agriculture Research Station (ARS), Navgaon, Alwar is constituent research station of Sri Karan Narendra Agriculture University,Jobner.This station is located 32 km from the Alwar Junction on the Sohna-Alwar Highway. It is 128 km away from Indira Gandhi International Airport, New Delhi and 175 km from Jaipur international airport. The station is situated at 27º38'54" N latitude and 76º51'58" Elongitude and 251 m above from mean sea level (MSL). This station has frontier in agriculture research since its inception and is an important research station of the university.

Identity of the unit

Rajasthan has classified in to ten agro-climatic zones to characterize climatic distribution of the state. The Flood Prone Eastern Plain Zone III b comprising all tehsils of Alwar, Bharatpur, Dholpur, Karauli and Sawai Madhopur districts except tehsils of Khandar, Chouth ka Barwara, Malarna Dungar and Sawai Madhopur. Average annual rainfall of the zone is 500-650 mm. Soils are alluvial in nature and prone to water logging. Although recurrent floods occur in rainy season in about 5% of the area, but with concern to agricultural production and productivity yet it is one of the most potential areas of Rajasthan. The region produces bajra, sorghum, maize, sugarcane, sesamum and a variety of pulses in the kharif season and wheat, barley, gram and mustard are the dominant crops during rabi season.

The centre was established by the State Department of Agriculture as a Seed Multiplication Farm in late fifties. The main objective was to multiply foundation and certified seeds of principal crops of the area. Research scheme on oilseeds and pulses (Non-Plan) was sanctioned in 1974-75 and the work of varietal screening and testing was initiated in Rapeseed-Mustard. In 1976, with the transfer of agricultural research to the university from state department of agriculture, the centre became Agricultural Research Sub Station, a constituent unit of the then Sukhadia University, Udaipur and later elevated to main station (Agricultural Research Station) with lead research functions on pulses and oilseeds. In 1981, a project on Intensification of Research and Training on Oilseeds and Pulses was sanctioned by ICAR to work out agronomic practices and rural social activities related to rapeseed–mustard and pulse crops. At this juncture NARP came into existence with an objective of strengthening the research capabilities of the station for solving location specific problems. The mandate of research was specified. In 1984, All India Coordinated Research Project on Oilseeds Improvement (R&M) was transferred from ARS, Durgapura, Jaipur to ARS, Navgaon, Alwar with the main responsibility of improvement of Rapeseed-Mustard group of crops in the state. A sub unit of the station was subsequently established at Kumher (Bharatpur) as Agriculture Research Sub Station in 1989, however, the sub-station became operative only in 1992 after completion of the formalities of acquisition of land allotted to it by the state government.

• Application of Gypsum @ 250 kg/ha for improving yield and quality was found better...
• When mustard is grown after kharif pulses like moong, urd and cowpea, it gave as much yield with 30 kg N/ha as with 60 kg N/ha...
• Maximum economic returns were obtained by sowing gram and mustard rows in the ratio of 3:1
• The basal application of PROM (Phosphate Rich Organic Manure) @ 300 kg/ha (40 kg P2O5/ha) significantly increased the yield of barley crop as compared to sole application of DAP.
