Abstract

Our accustomed agricultural practices of tilling the soil continuously and excessive fertilizer applications caused not only a decrease in organic carbon content and soil degradation but also disturbed environmental harmony. With this backdrop, current study was carried out during rainy (kharif) seasons of 2018 and 2019 at the research farm of Trihut College of Agriculture, Dholi, Pusa, Bihar to evaluate the effect of different tillage and nutrient management practices on maize (Zea mays L.). The experiment was laid out in split-plot design with tillage as the main plot and nutrient management as the sub-plot. The results showed significantly superior maize grain yield in PB (6.1, 6.2 mg/ ha) and 60% RDN+GSGN (6.0, 5.9 mg/ha) over CT (4.9, 5.0 mg/ha) and RDF (5.1, 5.4 mg/ha) during 2018 and 2019. Similar trend was followed in stover yield, net returns and B:C ratio. Among path analysis, harvest index and no of grains/cob observed largest direct path coefficient of yield attributes to determine the maize grain yield and stover yield respectively. The results suggest that the adoption of conservation tillage and precise nutrient management practices will help in the realization of better yield with maximum profit by way of reducing the input capital apart from improving soil health thereby sustaining natural resources for future generations.

耕作与精准养分管理对可收割玉米产量的影响

我们习惯的连续耕作和过度施肥不仅导致土壤有机碳含量下降和土壤退化，而且破坏了环境和谐。在此背景下，本研究于2018年和2019年雨季在比哈尔邦普萨邦德里特里胡特农业学院的研究农场进行，以评估不同耕作和营养管理措施对玉米(Zea mays L.)的影响。试验采用分块设计，以耕作为主，养分管理为辅。结果表明，2018年和2019年，PB(6.1、6.2 mg/ha)和60% RDN+GSGN(6.0、5.9 mg/ha)处理的玉米产量显著优于CT(4.9、5.0 mg/ha)和RDF(5.1、5.4 mg/ha)处理。秸秆产量、净收益和B:C比也有类似的变化趋势。通径分析中，收获指数和粒数/芯数对玉米籽粒产量和秸秆产量的直接通径系数最大。结果表明，采用保护性耕作和精确的养分管理措施，在改善土壤健康的同时，可以通过减少投入，实现更高的产量和最大的利润，从而为子孙后代保留自然资源。
