摘要

在2022-2023年的拉比季节，在印度Prayagraj (UP) Sam Higginbottom农业技术与科学大学Naini农业研究所农学系作物研究农场进行了一项田间试验。研究硫(20、30、40 kg/ha)和锌(15、20、25 kg/ha)的反应。试验采用随机区组设计，9个处理重复3次。结果表明，硫40 kg/ha +锌25 kg/ha处理9的株高(164.2 cm)、干重(165.8 g/株)、作物生长率(15.9 g/m2/d)、单株穗轴数(2.33)、单穗轴粒数(533.8)、籽粒产量(6.42 t/ha)和秸秆产量(14.36 t/ha)均显著高于对照。较高的总收益(1,30,264.40卢比/公顷)，较高的净收益(9,007.65卢比/公顷)和最大的B:C比(2.23)也记录在处理9(硫40公斤/公顷+锌25公斤/公顷)。

Influence of Sulfur and Zinc on Growth and Yield of Rabi Maize (Zea mays L.)

A field experiment was carried out at Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (UP) India, during the rabi season of 2022-2023. To study the response of sulfur (20,30,40 kg/ha) and zinc (15,20,25 kg/ha). The experiment was laid out in Randomized block design with 9 treatments replicated thrice. Results showed that the plant height (164.2 cm), dry weight (165.8 g/plant), Crop growth rate (15.9 g/m2/day), number of cobs per plant (2.33), number of grains per cob (533.8), grain yield (6.42 t/ha) and stover yield (14.36 t/ha) were recorded in treatment 9 with the application of Sulfur 40 kg/ha + Zinc 25 kg/ha. Higher gross returns (INR 1,30,264.40/ha), higher net returns (INR 90,007.65/ha) and maximum B:C ratio (2.23) were also recorded in treatment-9 (Sulfur 40 kg/ha + Zinc 25 kg/ha).
