EFFECT OF PLANTING METHOD AND NITROGEN LEVELS ON THE YIELD AND YIELD ATTRIBUTES OF WHEAT

A field trial was conducted during the winter season of 2001-2002 to find out the effect of planting method and nitrogen levels on wheat. Effects of two planting methods viz. bed planting and conventional planting were studied on three nitrogen levels viz. 50, 100 & 150 kg /ha on wheat (var. Protiva). Planting methods exhibited significant variation in respect of all the characters studied. The maximum grain yield (3.60 t/ha) was obtained from bed planting. Different levels of nitrogen significantly influenced on yield and yield attributing parameters of wheat. The highest grain yield (3.70 t/ha) was recorded from 150 kg N per hectare. The interaction effects of planting methods and nitrogen levels showed the significant difference in respect of spike/m 2 , spike length and grain yield. Highest grain yield (4.04 t/ha) was obtained at bed planting using 150 kg N per hectare. Though higher rate of N are used but lodging of plant height was not noticed. The correlation analyses showed that the rate of change of grain yield was highly dependent upon the rate of change of yield contributing characters of wheat.
