Evaluation of Different Zinc Fertilizer Application Methods …
Abstract
Rice (Oryza sativa) is a staple food crop for more than half of the world's population, and its cultivation is crucial for food security, particularly in Asia. Zinc (Zn) is a crucial micronutrient for optimal rice growth, yet its deficiency, particularly in nutrient-poor soils, poses a significant challenge to achieving high yields. A field experiment was conducted in Rautahat, Nepal, to assess the impact of different zinc fertilizer application methods on the growth and yield of spring rice (Oryza sativa L. var. Hardinath Hybrid-1) with the aim of identifying the most effective zinc application strategy for enhancing rice production. In this experiment, significant variation was observed with various methods of zinc application on the growth and yield of spring rice. The results showed that treatment with combined soil application and foliar spray produced the highest plant height (97.11 cm) and the greatest number of tillers per hill (19.58). Similar treatment had the longest panicle length (26.50 cm) while the control had the shortest panicle length (23.2750 cm). From the field experiment with different treatments, soil application and foliar spray recorded the highest thousand grain weight (21.50 g), grain yield (6.41 ton/ha), and straw yield (15.53 ton/ha). Foliar spray also showed strong performance across most parameters, ranking second in terms of plant height, grain yield, and straw yield, highlighting its potential as a supplementary application method. The results suggest that a combination of soil application and foliar spray is the most effective zinc fertilization strategy for improving the growth and yield of spring rice, as it enhances nutrient use efficiency by ensuring both immediate uptake and sustained availability. This integrated approach offers a promising solution for addressing zinc deficiencies in rice fields, leading to better crop performance and increased food production.
