Abstract
Micronutrient application rate and tillage practices are considered important factors in triggering the productivity of oilseed crops, especially canola (Brassica napus L.). The soil in the area is deficient in available zinc (Zn) and sulfur (S), which necessitates the supplementary application of these nutrients for sustainable crop development. The following study was conducted to evaluate the interactive effect of tillage and micronutrient on the growth, quality, and yield of canola and weed density. The present study was executed consisting of two tillage systems along with four treatments of micronutrients application including control, soil application of recommended doses of zinc (10 kg ha−1), soil application of a recommended dose of sulfur (45 kg ha−1), and combined application of a recommended dose of Zn + S (10 kg + 45 kg ha−1) during the crop growing seasons of 2019–2020 and 2020–2021. The results showed that the combined use of Zn and S under different tillage systems significantly affected crop growth, yield, and quality parameters. An increase of 0.99% in plant height, 6.33% in number of branches, 33% in silique length, 6.25% number of siliques per plant, 10% in number of seeds per silique, 4.64% in thousand seed weight, 0.74% in grain yield, and 0.42% in biological yield was recoded under conventional tillage practices as compared to zero tillage. In crux, the combined application of Zn and S at 10 and 45 kg ha−1 respectively, to canola crops under conventional tillage practices could be a sustainable option to improve canola crop growth, yield, and productivity.
期刊介绍：
IJPP publishes original research papers and review papers related to physiology, ecology and production of field crops and forages at field, farm and landscape level. Preferred topics are: (1) yield gap in cropping systems: estimation, causes and closing measures, (2) ecological intensification of plant production, (3) improvement of water and nutrients management in plant production systems, (4) environmental impact of plant production, (5) climate change and plant production, and (6) responses of plant communities to extreme weather conditions.
Please note that IJPP does not publish papers with a background in genetics and plant breeding, plant molecular biology, plant biotechnology, as well as soil science, meteorology, product process and post-harvest management unless they are strongly related to plant production under field conditions.
Papers based on limited data or of local importance, and results from routine experiments will not normally be considered for publication. Field experiments should include at least two years and/or two environments. Papers on plants other than field crops and forages, and papers based on controlled-environment experiments will not be considered.
