Abstract

An ongoing long-term experiment started since 1967, were selected during rabi season of 2014–2015 at Research Farm of Department of Soil Science, CCS Haryana Agricultural University, Hisar. The experiment consisting combination of two level of FYM (0 and 15 t/ha) and three mode of application (kharif, rabi, and both kharif and rabi) in main plots whereas, two level of nitrogen (0 and 120 kg/ha) and two weed control treatment (weed free and weedy check) in subplots was laid out in split-plot design. Based on the research investigation, it was observed that highest wheat yield and nutrient uptake by crop were significantly higher where FYM 15 t/ha was applied in both rabi and kharif season as compared to other treatments. Similarly, application of 120 kg N/ha significantly increased crop yield as compared to treatment where no nitrogen was applied. Weed density of A. arvensis and M. indicus decreased with increasing fertility level, whereas, density of C. didymus, R. dentatus, and miscellaneous weeds, total dry matter of weeds along with uptake and content of NPK in weeds increased with increasing fertility level. Gross returns, net returns and B:C were maximum under application of 15 t/ha in both rabi and kharif season along with 120 kg N/ha under weed free conditions. The combined application of FYM 15 t/ha in both rabi and kharif season along with 120 kg N/ha under weed free conditions gave significantly higher value of growth and yields of wheat and its economic returns.

摘要

一项自 1967 年开始的长期实验，在2014-2015 年狂犬病季节期间在希萨尔CCS 哈里亚纳邦农业大学土壤科学系研究农场进行选择。两个水平FYM的（0和15吨/公顷）和应用三种模式（实验由组合夏播，拉比，并且两个秋收和早春）在主情节而，二级氮（0和120公斤/公顷）的子地块中的两种杂草控制处理（无杂草和杂草检查）采用裂区设计。根据研究调查，有人认为最高小麦产量及养分吸收，利用作物均显著较高，其中厩肥15吨/公顷，这两个应用拉比和秋收季节与其他治疗相比。类似地，与不施氮的处理相比，施用 120 kg N/ha 显着提高了作物产量。A. arvensis和M. indicus 的杂草密度随着肥力水平的增加而降低，而C. didymus、R. dentatus和杂草的密度、杂草的总干物质以及杂草中 NPK 的吸收和含量随着肥力的增加而增加等级。总收益，净回报和B：C是下的应用15吨/公顷在两个最大拉比和秋收季节120公斤氮/杂草自由条件下公顷沿。FYM 15 t/ha 在狂犬病和kharif季节加上 120 kg N/ha 在无杂草条件下显着提高了小麦的生长和产量价值及其经济回报。
