Evaluation of maize (Zea mays) genotypes under different nitrogen levels in a Trans-Gangetic Plains region
An experiment was conducted during rainy (kharif) seasons of 2021 and 2022 at the research farm of ICARIndian Agricultural Research Institute, New Delhi to study the effects of different genotypes and nitrogen levels on growth and yield of maize (Zea mays L.). Six maize genotypes (‘AH 4271’, ‘DKC 9164’, ‘PJMH 1’, ‘PMH 13’, ‘PC 4’ and Pusa Vivek QPM 9’ Improved (PV QPM 9-I) and 7 levels of nitrogen (0, 40, 80, 120, 160, 200 and 240 kg N/ ha) were evaluated using factorial randomized complete block design with two replications. Results showed that among the genotypes the ‘DKC 9164’ produced the highest kernel yield and resulted in maximum net returns (` 78.0 and 82.8 × 103 /ha) as compared to other genotypes. The growth parameters and yield increased with the increasing level of nitrogen from 0 to 240 kg/ha. Application of nitrogen @240 kg N/ha produced the maximum plant height, total number of leaves, leaf area index and stover as well as biological yield, whereas the maximum kernel yield and net returns (` 91.1 & 97.2 × 103 /ha) were obtained with 200 kg N/ha which was at par with 160 kg N/ha
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.
