Impact of High Density Planting and Weed Management Practices on Yield Attributes, Yield and Quality Characters of Bt Cotton
Year: 2017
Type: article
Abstract: Vigilant production and economic strategies are important for cotton growing farmers to sustain the productivity due to expanding cost of cultivation and stagnating yields A field experiment was conducted during kharif, 2015 to evaluate with four planting densities 55,555 plants ha-1, 1,11,111 plants ha-1, normal planting, and paired row planting, 1,48,148 plants ha-1 and 4 weed management practices (pendimethalin 1.0 kg ha-1 as PE fb pyrithiobac sodium 62.5 g ha-1+quizalofop-p-ethyl 50 g ha-1 at 20, 40, 60, DAS, early PoE application of pyrithiobac sodium 62.5 g ha-1+quizalofop-p-ethyl 50 g ha-1 at 15 DAS fb glyphosate ammomium salt 2.13 kg ha-1 at 45 DAS, PE application of pendimethalin 1.0 kg ha-1 fb HW at 20 and 45 DAS and unweeded control. Plant density of 1,11,111 plants ha-1 (60 cm x 15 cm) produced significantly more kapas yield (3134 kg ha-1), Among the weed management practices, pre emergence application of pendimethalin 1.0 kg ha-1 fb PoE tank mix application of pyrithiobac sodium 62.5 g ha-1+quizalofop-p-ethyl 50 g ha-1 at 20, 40, 60 DAS recorded more kapas yield (3119 kg ha-1) and ginning % and was comparable with two other weed management practices. Plant densities did not influence lint index, ginning % and seed index.
