摘要

2020-21 年冬季（腊月），北方邦米尔扎布尔拉吉夫-甘地南校区（巴纳拉斯印度教大学）研究农场进行了一项盆栽试验，研究氮磷钾对晚播冬小玉米（Zea mays L.）生长和产量属性的影响。在完全随机设计中，处理包括 7 个水平的推荐剂量肥料（RDF），即氮磷钾，即对照、20% RDF、40% RDF、60% RDF、80% RDF、100% RDF 和 120% RDF，重复三次。与其他处理相比，氮磷钾水平的每次增加都能显著提高小玉米的生长和产量参数，即株高、叶面积/株、叶片数/株、叶绿素 a 和叶绿素 b、干重/株、第一棒收获期和总收获期、小棒/株、小玉米长度和周长、小棒和小玉米重量、小棒：小玉米比、小棒、玉米和饲料产量（克/株），直至最高水平。结果表明，晚播冬小玉米可施用 150-75-50 千克氮磷钾/公顷，以获得更高的产量。

Growth and yield of late sown winter baby corn (Zea mays) as influenced by NPK levels

A pot experiment was conducted during winter (rabi) season of 2020–21 at research farm of Rajiv Gandhi South Campus (Banaras Hindu University), Mirzapur, Uttar Pradesh to study the effect of NPK on growth and yield attributes of late sown winter baby corn (Zea mays L.). Treatment consisted of 7 levels of recommended dose of fertilizer (RDF) i.e. NPK, viz. control; 20% RDF; 40% RDF; 60% RDF; 80% RDF; 100% RDF; and 120% RDF in completely randomized design, replicated thrice. Each increment in NPK levels, significantly enhanced the growth and yield parameters of baby corn, viz. plant height, leaf area/plant, number of leaves/plant, chlorophyll a and Chlorophyll b, dry weight/plant, first cob harvest and total harvest period, baby cobs/plant, baby corn length and girth, baby cob and baby corn weight, baby cob:baby corn ratio, baby cob, corn and fodder yield (g/plant) up to the highest level than other treatments. The results suggest that late sown winter baby corn can be applied with 150– 75–50 kg NPK/ha for higher yields.

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.
