Abstract

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.

Mechanismauthor interpretationoriginal resultpositivemeasured

Claim · model-written summary

The higher seed cotton yield at 20 cm spacing with 100 kg nitrogen was attributed to more branches, bolls per plant, boll weight and seed weight.

Outcome
seed cotton yielde2
Qualifier
more number of monopodial, sympodial branches, number of bolls per plant, Average boll weight and 100 cotton seed weighte5
