Abstract

A field experiment was conducted during the rainy (kharif) seasons of 2021 and 2022 at the research farm of Acharya Narendra Deva University of Agriculture and Technology, Kumarganj Ayodhya, Uttar Pardesh, to evaluate the effect of graded doses of biochar and fertility levels with and without biofertilizer under partially reclaimed sodic soils on maize (Zea mays L.) performance. The experiment was laid out in randomized block design (RBD) which with 3 replications. Experiment comprised of 8 treatments, viz. T1 , Control; T2 , 100% RDF 100 : 60 : 40 N, P2 O5 and K2 O; T3 , 50% RDF + 2.5 t/ha biochar; T4 , 50% RDF + 2.5 t/ha biochar + ZMB Biofertilizer; T5 , 50% RDF + 2.5 t/ha biochar + ZMB Biofertilizer + Zn; T6 , 100% RDF + 5 t/ha biochar; T7 , 100% RDF + 5 t/ha biochar + ZMB Biofertilizer; T8 , 100% RDF + 5 t/ha biochar + ZMB Biofertilizer + Zn. The study’s comparative analysis revealed the positive effects of applying biochar, optimal fertility levels, and biofertilizers on the yield attributes and grain yield of kharif maize. Notably, treatment T8 showed significant improvements, with a 53% increase in cob length, 34% increase in cob girth, 83% increase in the number of grains per row, 138.4% increase in grain yield, and 134% increase in stover yield compared to the control treatment. These findings demonstrate the successful impact of application of 100% RDF + 5 t/ha biochar + ZMB Biofertilizer + Zn in enhancing various aspects of maize growth and yield, surpassing the outcomes achieved with the control treatment and may be recommended for achieving high-quality maize production in partially reclaimed sodic soils of eastern Uttar Pradesh and comparable agro-ecoregions.

不同剂量生物炭、肥力水平和生物肥料处理下的哈里夫玉米（玉米）生长、产量属性和谷物产量比较分析

2021 年和 2022 年雨季期间，在北方邦库马甘杰阿约提亚的阿查里亚-纳伦德拉-德瓦农业和技术大学研究农场进行了一项田间试验，以评估在部分开垦的钠质土壤中，分级剂量的生物炭以及施用和不施用生物肥料的肥力水平对玉米（玉米）产量的影响。实验采用随机区组设计（RBD），3 次重复。试验包括 8 个处理，即：T1，对照；T2，100% RDF 100 : 60 : 40 N、P2 O5 和 K2 O；T3，50% RDF + 2.5 吨/公顷生物炭；T4，50% RDF + 2.5 吨/公顷生物炭 + ZMB 生物肥料；T5，50% RDF + 2.5 t/ha 生物炭 + ZMB 生物肥 + Zn；T6，100% RDF + 5 t/ha 生物炭；T7，100% RDF + 5 t/ha 生物炭 + ZMB 生物肥；T8，100% RDF + 5 t/ha 生物炭 + ZMB 生物肥 + Zn。该研究的比较分析表明，施用生物炭、最佳肥力水平和生物肥料对哈季玉米的产量属性和籽粒产量有积极影响。值得注意的是，与对照处理相比，T8 处理的玉米棒长度增加了 53%，玉米棒周长增加了 34%，每行籽粒数增加了 83%，籽粒产量增加了 138.4%，秸秆产量增加了 134%。这些研究结果表明，施用 100% RDF + 5 吨/公顷生物炭 + ZMB 生物肥料 + Zn 成功地提高了玉米生长和产量的各个方面，超过了对照处理所取得的成果。

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.
