Research Unit 3: Regional Research Sub-Station, Jalalgarh, Purnea

The Irrigation Research Station in Araria, established in 1974, plays a key role in advancing irrigation research and improving water management practices in the region. By focusing on efficient irrigation technologies, water conservation, soil moisture management, and climate adaptation, the station supports agricultural productivity and sustainability.
Mandate of Regional Research Sub-Station, Jalalgarh
· Identification of location specific researchable issues in Agriculture and allied discipline and conducting research on priority areas.
· Identification in major cereals, oilseeds, pulses and fiber crops.
· Promotion of highdensity orchards, protected cultivation of fruits and vegetables
· Soil health management
· Integrated disease and pest management
Research activities
The Regional Research Sub-Station (RRSS), Jalalgarh, has been actively engaged in agricultural research to enhance crop productivity in the region. During 2020-21, two trials, AVT-IR-LS-TAS and AVT-IR-TS-TAS, were conducted under the All India Coordinated Research Project (AICRP) - North Eastern Plains Zone (NEPZ). Among the twelve entries tested in AVT-IR-LS-TAS, the entry NELS201 recorded the highest yield, while in AVT-IR-TS-TAS, NETS108 showed the best performance. In 2021-22, four trials, including AVT-IR-LS-TAS, AVT-IR-TS-TAS, and SPL-MABB-IR-TS, were conducted at RRSS Jalalgarh under AICRP-NEPZ. The entries NELS201, NETS105, NERI302, and HD3411 were recorded with the maximum yields, respectively, based on the mean values. Additionally, a two-year study (2019-2021) at the station focused on evaluating the impact of different sulfur doses on growth, yield, sulfur uptake, and oil content in the mustard-soybean cropping system for the Koshi region of Bihar. The application of sulfur at 40 kg/ha in sole mustard crop resulted in higher seed yield, oil content, sulfur uptake, and a better benefit-cost ratio. In the 2020-23 Rabi season, an SVT trial in a Randomized Block Design (RBD) with three replications was conducted at RRSS Jalalgarh, involving eight entries. Among these, SVT(LS-2022)-12, SVT(LS-2022)-15, and SVT(LS-2022)-13 were found to be statistically superior based on the average mean value. These research efforts by RRSS Jalalgarh demonstrate a commitment to enhancing the agricultural productivity of Bihar through meticulous trial evaluations and research-based recommendations.
