Effect of nitrogen levels and plant spacing on growth and yield of cotton.

Growth and yield response of cotton to different nitrogen levels and plant spacing was studied at farmer’s field at Tandlianwala, Faisalabad. The experiment comprised three plant spacings viz. 10, 20 and 30 cm with three nitrogen levels i.e. 50, 100 and 150 kg ha. Plant spacing and nitrogen levels had significant differences for yield components and seed cotton yield. Plant spacing of 20 cm with nitrogen level of 100 kg ha produced more seed cotton yield due to more number of monopodial, sympodial branches, number of bolls per plant, Average boll weight and 100 cotton seed weight. So, to grow cotton under agro-ecological conditions of Tandlianwala, Faisalabad, plant spacing of 20 cm and 100 kg nitrogen per hectare is recommended.
