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

Description

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.

Steps to reproduce

Five levels of NPS fertilizers (0, 50, 100, 150, and 200 kg ha-1) and three levels of weeding frequency (W1, W2, and W3 as one-time, two-time, and three-time weeding, respectively) were put out in an RCB design and reproduced three times. The testing material was HB1307 variety.
