Abstract:

A field experiment entitled “Effect of fly ash and nitrogen on the growth and yield of Bt cotton (Gossypium hirustum L.)” was conducted during the kharif season of 2018 at Research Farm of Guru Kashi University, Talwandi Sabo, Bathinda (Punjab). The soil of the experimental field was loamy sand, low in organic carbon and available nitrogen, medium in available potassium and phosphorus. The trail was laid out in split plot design with two levels of fly ash viz. 0 and 10 t ha-1 in main plots and four levels of Nitrogen (0,125,150 and 175kg ha-1) in sub plots. The results showed that the fly ash 10t ha-1 gave significantly higher growth and yield attributes over control. Application of nitrogen 175 kg ha-1 gave significantly higher plant height, dry matter accumulation, leaf area index, number of sympodial branches per plant, number of bolls per plant, boll weight, seed cotton yield ,stalk yield and biological yield as compared to 0, 125, 150kg N ha-1. The results showed that application of nitrogen 175kg N ha-1 gave significantly higher seed cotton yield (104, 23.8, 3.9%) over 0, 125, 150kg N ha-1 respectively. On the basis of present investigation, it can be concluded that 175 kg N ha-1 gave higher growth and yield attributes but at par with the application of 150 kg N ha-1.
