摘要
在Balkh大学农业研究农场，采用随机完全区组设计(RCBD)分3个重复试验，研究了尿素施肥对玉米产量及产量构成因素的影响。试验尿素用量分别为0、80、160和240 kg ha-1。氮肥(尿素)用量对玉米产量有显著影响(p<0.05)。施氮水平越高，籽粒产量、穗粒数、穗行粒数、穗径、穗轴长、单株粒数和株高越高。结果表明，施氮肥240 kg hm -1时高产7.76 t hm -1，施氮肥0 kg hm -1时低产5.12 t hm -1。结果表明，建议施用240 kg hm -1氮肥。
Evaluation of Nitrogen (Urea) on Zea mays L. under Balkh Province Climate
An experiment was conducted to evaluate effect of urea fertilizer on yield and yield components of Zea mays L. Using Randomized Complete Block Design (RCBD) split plots in three replications in agricultural research farm of Balkh University by 2019. Doses of urea used in this experiment were 0, 80, 160 and 240 kg ha-1, respectively. It has been found that amount of nitrogen fertilizer (urea) had significant effect on yield of maize at p<0.05. The higher level of nitrogen caused the higher grain yield, number of kernels per ear, the number of grains per ear row, ear diameter, cob length, grain per plant and plant height. As a result 7.76 ton ha-1 was recorded as high yield while 240 kg ha-1 urea was used, and 5.12 ton ha-1 was recorded as low yield in treatment one with 0 kg ha-1 of nitrogen fertilizer. Finally, as a result using 240 kg ha-1 nitrogen fertilizer is recommended.
