A field study was carried out during the two consecutive kharif seasons of 2012 and 2013 at the Agricultural Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, to evaluate the effect of cultivars and weed management practices on weed dynamics, yield attributes, yields and economics in zero-till direct-seeded rice (Oryza sativa L.). The dominant weed flora were Echinocloa colona, Echinocloa crus-galli, Cynodon dactylon, Cyperus rotundus, Cyperus iria, Caesulia auxillaries and Eclipta alba. Among rice cultivars, Arize-6129 had minimum weed density (425.9 and 480.1/m) and dry weight (76.7 and 86.4 g/m 2 ), and maximum of grain yield (4.29 and 4.12 t/ha) during both the years, respectively. Among the weed management practices, application of bispyribac sodium + azimsulfuron (25 g +35 g/ha) + 0.25% NIS (post-emergence) at 15-20 DAS proved to be most effective in minimizing the weed density, weed dry weight and increased rice grain yield (4.33 and 4.16 t/ha, respectively). Arize-6129 produced maximum net returns (`40402 and 37804/ha) and benefit: cost ratio (1.61 and 1.51) and economic efficiency (`316 and 298/ha day), respectively during both the years. Among weed management practices, application of bispyribac sodium + azimsulfuron (25 g +35 g/ha) + NIS (0.25%) was the most economical and efficient. © 2019 Indian Council of Agricultural Research.

Effect of fertility levels and bioinoculants on productivity, profitability, quality and nutrient acquisition of clusterbean (Cyamopsis tetragonoloba)
(Indian Society of Agronomy, 2014) Animesh Singh; N.L. Jat; Raghavendra Singh; Suresh Pal
A field experiment conducted during the rainy (kharif) season 2008 at Jobner, Rajasthan, to evaluate that effect of fertility and bioinoculants on productivity, nutrient uptake and quality of clusterbean [Cyamopsis tetragonoloba (L.) Taub.]. The application of 75% recommended dose of fertilizer along with seed inoculation with Rhizobium significantly resulted in more number of effective nodules/plant (19.4), nodules dry weight/plant (17.8 mg), clusters/ plant (17.5), seed (1.10 t/ha) and stover yield (2.99 t/ha) and profitability over seed inoculation of PSB, Rhizobium and control. Nitrogen and phosphorus uptake by seed and stover were also significantly higher with 75% recommended dose of fertilizer along with Rhizobium over PSB, Rhizobium and control. Significantly higher protein content (27.81%) was recorded with application of 75% recommended dose of fertilizer along with Rhizobium over PSB, Rhizobium and control. Gum content (29.20%) was also higher with application of 75% recommended dose of fertilizer along with Rhizobium. © 2014, Indian Society of Agronomy. All rights reserved.
