Abstract

The experiment was conducted in crop research farm in department of Agronomy during Zaid season of 2022 on Pearl millet crop. The treatment consisted of three levels of NPK (50,75 and 100%) and Zinc (10,15 and 20 kg/ha) and a control. The experiment was laid out with a randomize block design (RBD) with ten treatments which are replicated thrice as T1 : 50% NPK kg/ha + Zinc 10 kg/ha, T2 : 50% NPK kg/ha + Zinc 15 kg/ha, T3: 50% NPK kg/ha + Zinc 20 kg/ha, T4 : 75% NPK kg/ha + Zinc 10 kg/ha, T5 : 75% NPK kg/ha + Zinc 15 kg/ha, T6 : 75% NPK kg/ha + Zinc 20 kg/ha , T7 : 100% NPK kg/ha + Zinc 10 kg/ha, T8 : 100% NPK kg/ha + Zinc 15 kg/ha, T9 : 100% NPK kg/ha + Zinc 20 kg/ha and a T10 : Control. Application of 100% NPK kg/ha combination with Zinc 20 kg/ha was recorded significantly higher plant height (192.43 cm), plant dry weight (42.54 g/plant), ear head length (18.10 cm) number of grains per ear head (1658), grain yield (2.62 t/ha), stover yield (3.33 t/ha), harvest index (43.99%). Maximum gross returns (1,30,750.00INR/ha), net returns (89,939.00INR/ha) and higher Benefit cost ratio (2.22).

氮磷钾和锌水平对珍珠粟生长和产量的影响

试验于2022年扎伊德季节在农学系作物研究农场进行。施用氮磷钾(50%、75%和100%)和锌(10、15和20 kg/ hm2) 3个水平和一个对照。实验提出了随机区组设计(RBD)十治疗是复制三次T1: 50%氮磷钾公斤/公顷+锌10公斤/公顷,T2: 50%氮磷钾公斤/公顷+锌15公斤/公顷,T3: 50%氮磷钾公斤/公顷+锌20公斤/公顷,T4: 75%氮磷钾公斤/公顷+锌10公斤/公顷,T5: 75%氮磷钾公斤/公顷+锌15公斤/公顷,T6: 75%氮磷钾公斤/公顷+锌20公斤/公顷,T7: 100%氮磷钾公斤/公顷+锌10公斤/公顷,显示100%氮磷钾公斤/公顷+锌15公斤/公顷,T9:氮磷钾公斤/公顷100% + 20公斤/公顷和锌T10:控制。100%氮磷钾kg/ha配施锌20 kg/ha后，水稻株高(192.43 cm)、株干重(42.54 g/ha)、穗长(18.10 cm)、穗粒数(1658粒)、籽粒产量(2.62 t/ha)、秸秆产量(3.33 t/ha)、收获指数(43.99%)显著提高。最大总收益(1,30,750.00印度卢比/公顷)，净收益(89,939.00印度卢比/公顷)和更高的收益成本比(2.22)。
