The field experiments were conducted at ICAR-Indian Agricultural Research Institute (IARI),21 st March 2024, Assam Gogamukh, Assam research field located at Dhirpai Chapori, Gogamukh, Dhemaji, Assam. Simultaneously the field experiments were also conducted at farmers’ fields in the Lakhumpur district. The five pusa mustard varieties viz., PM-25, PM-26, PM-27, PM-28, PM-33 and one local control were evaluated. The fertilizer applied N: P2O5: K2O at 60:40:40 in the form of urea, DAP, and MOP along with 20 kg sulfur in the elemental form. Further, 10 t FYM/ha was applied before sowing. The spacing was 40 cm row to row and 20 cm plant to plant and sown during the last week of December 2022. Similarly, five pusa lentil varieties viz., L4717, L4727, L4729, PDL1, PSL 9, and one local variety were evaluated. The fertilizer applied N: P2O5: K2O at 20:40:0 in the form of DAP Further, 10 t FYM/ha was applied before sowing. The spacing was 22.5 cm row to row and 5 cm plant to plant and sown during the first week of January 2023.
The pusa mustard varieties, PM-27 recorded a higher grain yield (41-42%), and straw yield by 21 %; PM-25 recorded a 24-30% higher grain yield and straw yield of 10 % and PM-26 was recorded 26-28 % higher grain yield and straw yield by 10 % compared to local check. Moreover, all the above three pusa mustard varieties recorded a harvest index of 10-11 % higher than local control. The pusa lentil varieties viz., L4717, L4727, PSL9, L4729, and PDL1 were recorded yield advantages of 45-48 %, 30-35%, 27-29%, 22-25%, and 12-14% respectively higher over local control. Further, L4717 found a higher harvest index of 32-33 % over local control. Therefore, the pulse residues may be incorporated into the soil to maintain the soil fertility and enhance crop productivity. Thus, Pusa mustard and lentil varieties may increase the pulses and lentil production when rice-fallow is replaced by rice pulses/lentils and may be cultivated by using residual soil moisture after harvesting rice.
