The effect of N-fertilizer top dressing on yield and seed protein in barley was carried out at Mae Hae Research and Training Station, Faculty of Agriculture, Chiang Mai University. Five rates of nitrogen fertilizer 0, 5, 10, 15 and 20 kgN/rai, were applied as top dress to BRW.9 variety...
effect of fertilizer on crop yield 率增加,但起始时的肥料效应比较明显,此时总产量曲线的斜率较大。而后表现平缓,超过最高点后,总产量随施肥量的增加而减少。 综上所述,在一定的生产条件下,施肥量与产量之间的关系一般呈曲线形式。当作物严重缺乏某种养分时,增施该养分的增产量,起初往往是递增,即增施单位量养分...
Under different nitrogen application patterns, the yield of corn and the nitrogen fertilizer's efficiency were analyzed. The results indicated that the yield of N-fertilizer treatments were higher than no N-fertilizer in basal and dressing application. The yield by 150kg/hm2 urea application was th...
