A field experiment was conducted during two consecutive years of Kharif 2012 and 2013 at Agricultural Research Station, Banswara to find out suitable weed management strategies for Bt cotton. The experiment was laid-out in Randomized Block Design with three replications having nine treatments. Results revealed that, the application of pendimethalin 30% EC @ 0.75 kg a.i. / ha PE fb quizalofop-P-ethyl 50 g a.i. / ha at 20-30 DAS + one hoeing gave significantly higher bolls plant-1 (36.30), boll weight (4.22 g), seed cotton yield (2275 kg ha-1), net return (Rs.55581/-ha-1) and B:C (2.70) over rest of treatments, but it was found at par with weed free check and application of pyrithiobac sodium @ 62.5 g a.i./ ha fb quizalofop-P-ethyl 50 g a.i./ha at 20-30 DAS + one hoeing bolls plant-1 (34.84), boll weight (4.19 g), seed cotton yield (2251 kg ha-1), net return (Rs.54669/-ha-1) and B:C (2.64). The maximum weed control efficiency (60.75%), lowest weed population (12.39 m-2) and weed dry matter accumulation (14.63 g m-2) at 60 DAS were observed under application of pendimethalin 30% EC @ 0.75 kg a.i. / ha PE fb quizalofop-P-ethyl 50 g a.i. / ha at 20-30 DAS + one hoeing over rest of treatments. However, it was found at par with weed free check and application of pyrithiobac sodium @ 62.5 g a.i./ ha fb quizalofop-P-ethyl 50 g a.i./ha at 20-30 DAS + one hoeing.
Gujarat) during summer season of the year 2016 to study the effect of irrigation, vermicompost and sulphur on sesamum (Sesamum indicum L.). There were four irrigation schedules (IW: CPE ratios 0.4, 0.6 and 0.8 and irrigation at critical growth stages flowering, branching, capsule formation and seed filling stages), two vermicompost levels (0 and 2 t ha -1 ) and two sulphur levels (0 and 20 kg ha -1 ). Higher value of growth characters, yield attributes, seed and straw yield were recorded under treatment I 3 (0.8 IW: CPE ratio) which was at par with I 2 (0.6 IW: CPE ratio). Application of 2 t vermicompost ha -1 and 20 kg sulphur ha -1 significantly increase growth characters, yield attributes, seed and straw yield. The interaction of 0.8 IW: CPE ratio in combination with 2 t vermicompost ha -1 resulted in better seed yield.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
