Yield of direct seeded rice as influenced by Dhaincha intercropping

Intercropping of green manure in wet seeded rice for a brief spell of 35 to 40 days and incorporating in rice crop would encash the least detrimental effect of early shading, besides ensuirng 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 Dhaincha was sown in rice with drum seeder at 1: 2 ratio. Direct seeding of rice + two rows of Dhaincha in between recorded higher biomass and N content of Dhaincha. The same treatment registered higher grain yield (7630 kg ha⁻¹ and 7468 kg ha⁻¹) and straw yield (8900 kg ha⁻¹ and 8726 kg ha⁻¹) of rice.
