Effect of Planting Density and Weeding Regime on Yield Attributes and Yield of Drum Seeded Rice (Oryza sativa L.)
- B. N. Sandeep Nayak; Md. Mujeeb Khan; K. Mosha; P. Prasuna Rani
- Drum seeding of rice (Oryza sativa L.) involves a major change in the production practices for attaining optimal plant density and first-rate weed management practices for get in touch with higher productivity in the areas of Krishna Godavari zone of AP (INDIA). A field experiment was carried out to investigate the effects of weeding regime and planting density on yield attributes of drum seeded rice cv. NLR-33358 (SOMASILA). The maximum reduction of weed density and weed drymatter production was recorded in two cono weedings followed by two hand weedings at 20 and 40 DAS, pre-emergence application of pendimethalin @1 kg a.i. ha-1 post-emergence application of bispyribac sodium @ 20 g a.i ha -1 with a plant density of 71hills m-2. But, plant density 47 hills m-2 was superior to other plant densities with respect to rice grain yield. The highest grain yield (4275 kg ha-1) was achieved with plant density 47 hills m-2 (D2) in combination of cono weedings twice (W3) but remained at a par to hand weedings twice (4142 kg ha-1). The next best treatment was -emergence application of pendimethalin @1 kg a.i. ha-1 along with post-emergence application of bispyribac sodium @ 20 g a.i ha -1.
