| Abstract | ||
| From a pilot experiment at Shandwil Agricultural Research Station, the concentration of urea at 6% as foliar application was found the most favourable for wheat plants since it gave the highest yield of grain and straw without having foliar chlorosis or necrosis. To investigate the effect of foliar application of urea (6%) at dif-ferent growth stages of wheat in comparing with soil application (75kg N/fed), two field trials were carried out at the same location in 1989/90 and 1990/91 growing seasons. It was observed that grain and straw yields of plants received 25 kg N/fed., as soil application followed by three sprays at crown, tittering and booting stages were increased over the soil application (75 kg N/fed). N-, P- and K-uptake by wheat plants as well as grain protein content of the plants received three sprays were nearly the same as those received 75 kg N/fed. as soil application . It can be concluded that addition of 25 kgfed. before sawing fol-lowed by 3 sprays of urea (6%) could save 25 kg N /fed. | ||
