Abstract: Data on heading date, biomass, yield and yield components were collected to study the correlation coefficient and simple regression under water and phosphorus stress conditions. Yield per plant and plant height showed significant positive association with effective tillers per plant, spike length, spikelets per spike, florets per spike, grains per spike, biomass per plant, and negatively correlated with total tillers per plant. Total tillers per plant also showed significant positive correlation with 100-grain weight. Effective tillers per plant exhibited high positive correlation with grains per spike and biomass per plant. Grains per spike was positively correlated with biomass per plant but negatively with 100-grains weight. Hundred-grains weight had positive correlation with yield. The regression coefficients for plant height, spikelets per spike, florets per spike, spike length, biomass per plant, effective tillers per plant and grains per spike on yield per plant were positively significant.
