Abstract
A field study was conducted to determine the effects of different levels of irrigation and nitrogen on grain development (grain filling rate and grain filling duration) and grain yield of wheat (Triticum aestivum L.) variety Inqlab-91. The experiment was conducted at the Crop Physiology research area, University of Agriculture, Faisalabad, Pakistan, during the year 2002-03 and 2003-04. Four irrigation levels i,e one irrigation ( Irrigation at tillering stage), two irrigations ( irrigations at tillering and anthesis stages), three irrigations (irrigations at tillering, anthesis and grain development stages), four irrigations (irrigations at tillering, stem elongation, anthesis and grain development stages) and four nitrogen levels i.e, 0, 50
