Abstract:

A field experiment entitled influence of farmyard manure and nitrogen on growth and yield of Bt cotton (Gossypium hirsutum L.) was conducted at Research Farm of University College of Agriculture, Guru Kashi University, Talwandi Sabo, Bathinda to study the effect of different levels of farmyard manure (FYM) and nitrogen on growth and yield of Bt cotton during kharif season in 2019. The trial was laid out in split plot design with three levels of FYM (0, 15 and 30 t ha-1) in main plots and four nitrogen levels (0, 75, 100 and 125% of recommended dose of Nitrogen) in sub plots, replicated thrice. Farmyard manure @ 30 t ha-1 recorded significantly higher plant height (181.1 cm), dry matter accumulation plant-1 (306.1 g), number of monopodial branches plant-1 (2.4), number of sympodial branches plant-1 (35.2), number of bolls plant-1 (54.6), boll weight (15.4 g ), seed cotton yield (36.8 q ha-1), stick yield (55.7 q ha-1) and biological yield (92.5 q ha-1) than other control and 15 t ha-1. FYM @ 30 t ha-1 (36.8 q ha-1) resulted in 15.0 and 5.4% higher seed cotton yield than 0 and 15 t ha-1, respectively. Plant height (181.3 cm), dry matter accumulation plant-1 (321.1 g), number of monopodial branches plant-1 (2.6), number of sympodial branches plant-1 (38.3), number of bolls plant-1 (56.4), boll weight (16 g), seed cotton yield (37.5 q ha-1), stick yield (57 q ha-1) and biological yield (94.5 q ha-1) was recorded significantly higher in 125% RDN but it was statistically at par with the application of 100% RDN. The application of 125% RDN resulted in 21.8, 10.3 and 3.9% higher seed cotton yield than 0, 75 and 100% RDN, respectively.
