摘要

从试验结果可以看出，棉花作物对锌、镁叶面营养反应良好。在旱作条件下，叶面喷施这些营养物质可能是控制产量障碍的可行选择。进一步研究发现，分别在立交期、开花期和成铃期喷施1.0% MgSO4和0.5% ZnSO4 3次，可显著改善植株生长和籽棉产量。因此，这些处理可以推荐用于提高雨养棉花产量，但在推荐之前需要进行地点特异性验证。

Effect of foliar nutrition on growth and yield of cotton (Gossypium herbaceum) MCU 5

From the experimental results, it is inferred that cotton crop responds well to the foliar nutrition with zinc and magnesium. Application of these nutrients through foliar spray might be the feasible option to control the yield barrier under rainfed condition. Further the study found that foliar spraying of MgSO4 1.0% along with 0.5% of ZnSO4 three times respectively at squaring, flowering and boll formation stages markedly improved the plant growth and seed cotton yield. Thus, these treatments may be recommended for enhancing the rainfed cotton yield but location specificity verification is required before recommendation.

期刊介绍： The Indian Journal of Agricultural Sciences publishes papers concerned with the advancement of agriculture throughout the world. It publishes original scientific work related to strategic and applied studies in all aspects of agricultural science and exploited species, as well as reviews of scientific topics of current agricultural relevance. Specific topics of interest include (but are not confined to): genetic resources, all aspects of crop improvement,crop production,crop protection, physiology, modeling of crop systems, the scientific underpinning of agronomy, engineering solutions, decision support systems, land use, environmental impacts of agriculture and forestry, impacts of climate change, rural biodiversity, experimental design and statistical analysis, the application of new analytical and study methods (including molecular studies) and agricultural economics. The journal also publishes book reviews. Articles are accepted on the following broad disciplines: Agric. Engineering & Technology, Agric. Social & Economic Sci., Agronomy, Biometry, Biosciences, Cytology, Ecology, Environmental Sciences, Fertilization, Forestry , Genetics, Horticultural Sciences, Microbiology, Pest, Weed Control etc., Molecular Biology, Plant Pathology, Plant Breeding, Physiology and Biochemistry, Soil Sciences, Special Cultivation Technology, Stress Breeding, Agric. extension, and Cell Biology.
