Impact of Weeding frequency and Rates of NPS fertilizer on food barley Yield performances

The research was to determine the optimum rate of weeding frequency and blended NPS rate of fertilizer for barley yield. The results indicated that the greatest benefits of NPS fertilizer rates and weeding frequency were shown in days to 50% heading and days to 90% physiological maturity, with a very significant (P<0.01) effect.The combination effect of NPS fertilizer rates and weeding frequencies had a highly significant (P<0.01) effect on biomass yield, grain yield, straw yield, harvest index, spike length, number of effective tillers, tillers total/plant, thousand kernel weight, and plant height of food barley.
