Abstract :

Intercropping of green manure in wet seeded rice for a brief spell of 35 to 40days and incorporating in rice crop would encash the least detrimental effect of early shading, besides ensuring addition of green manure to rice crop. The field experiments were conducted in the wetland farms of Tamil Nadu Agricultural University, Coimbatore to evaluate the effect of Dhaincha incorporation on the agronomic yield of rice. The experiment was laid out in randomized block design with ten treatments. Accumulation of biomass in Dhaincha was distinctly increased when Dhainchawas sown in rice withDrum seeder direct seeding and two rows of Dhaincha in between rice (1:2) recorded higher biomass of 18.9 t ha-1 followed by rice direct seeding with drum seeder + one row Dhaincha in between (1:1) recording 14.2 t ha-1. Rice with green manure intercropping and incorporating in rice Direct seeding with drum seeder + two rows of Dhaincha in between (1:2) recordedhigher grain (7630 kg ha-1) and straw (8900 kg ha-1) yield respectively. The dynamics of Dhaincha intercropping and incorporation in direct seeded rice crop, its influence on agronomic yield, has been discussed in this paper.
