A field experiment was conducted during the Kharif season of two successive years 2007 and 2008.
The Effect of different levels of nitrogen and plant population on growth and yield of cotton
(Gossypium hirsutum L.) was conducted at Adaptive Research Farm Rahim Yar Khan in RCBD with
Split plot arrangement in three replications. Field trials to study the effect of nitrogen doses (28, 56
and 84 kg ha-1) and levels of plant population (74100, 98800 and 123500 plants ha-1) on growth and
yield of cotton variety BH-160 were evaluated. The levels of nitrogen and plant population
significantly affected the plant height, number of mature bolls plant-1, seed cotton weight boll-1, and
seed cotton yield ha-1. The interaction between nitrogen levels and plant population was non
significant in plant height and number of mature boll plant-1 while significant in boll weight and seed
cotton yield ha-1. Two years average data of yield and yield components showed that application of
nitrogen @ 84kg ha-1 gave significantly the highest seed cotton yield (2138 kg ha-1) over Nitrogen
doses of 28 and 56 kg ha-1. Plant population of 98800 plants ha-1 produced the highest seed cotton
yield (2234 kg ha-1). Maximum seed cotton yield (2327 kg ha-1) was produced at the Nitrogen level of
84 kg ha-1 and with plant population of 98800 plants ha-1.
