摘要

拉金德拉-普拉萨德博士中央农业大学于 2021-22 年 Rabi 季节在萨马蒂普尔的普萨进行了一项田间试验。试验采用分小区设计，主小区种植三个饲料燕麦品种（肯特、JHO-822 和本地），子小区种植四个不同的播种日期（11 月 15 日、11 月 25 日、12 月 5 日和 12 月 15 日），三次重复。试验结果表明，"JHO-822 "的青饲料产量和干饲料产量分别比当地品种高出 9.4%和 29.5%，气象指数（GDD、HTU 和 PTU）累计最高，HUE 和 PTUE 最高。在不同的微环境中，11 月 15 日播种的青饲料和干饲料产量最高，农业气象指数值也大幅提高，但随着播种日期的提前，农业气象指数值有所下降。每推迟一天播种，青饲料产量就会减少 0.7%，干饲料产量减少 1.2%。

Productivity and thermal requirement of fodder oat varieties under different micro-environments in Bihar

A field experiment was carried out at Dr. Rajendra Prasad Central Agricultural University, Pusa, Samastipur during Rabi season, 2021–22. The experiment was conducted using a split plot design with three varieties of fodder oat (Kent, JHO-822 and Local) in main-plots and four different sowing dates (15th November, 25th November, 5th December and 15th December) in sub-plots with three replications. The results obtained from the experiment showed that ‘JHO-822’ recorded 9.4 and 29.5% higher green and dry fodder yield than local variety and accumulated the highest meteorological indices (GDD, HTU and PTU) and resulted in the highest HUE and PTUE. Among different micro-environments, seeding on 15th November recorded the highest green and dry fodder yield with substantially greater values of agro-meteorological indices which decreased with advancement of sowing date. Per day delay in sowing resulted in 0.7% decrease in green fodder yield and 1.2% decrease in dry fodder yield.

期刊介绍： Indian Journal of Agronomy welcomes concise articles presenting original research data based on field experiments on all aspects of agronomy in different crops and related cropping systems. • The journal publishes only full length comprehensive articles based on new approaches/findings in English only. • Review articles are also considered but these are normally solicited by Editorial Board. However, the authors who wish to contribute a review on their own based on their standing in the relevant field may contact the Secretary or Chief Editor with a broad outline before submitting the manuscript.
