Studying the Effect of Feeding Rates and Seedling Thickness on the Yield of Rice Varieties

Abstract

The article describes the effect of nitrogen fertilizers on the yield of rice when grown in seedlings. This study investigates the influence of feeding rates and seedling thickness on the yield performance of various rice (Oryza sativa L.) varieties. Conducted under controlled field conditions, the experiment utilized a factorial design with multiple rice genotypes, varying nutrient (feeding) levels, and different seedling densities. Results indicated that both feeding rate and seedling thickness significantly affected grain yield, plant height, and tillering capacity. Optimal feeding rates combined with medium seedling thickness produced the highest yields, suggesting a synergistic interaction between nutrient availability and plant spacing. Moreover, varietal responses varied, with some cultivars showing greater adaptability to dense planting and high nutrient input. The findings highlight the importance of integrated crop management strategies tailored to specific varietal characteristics to maximize productivity. These results can guide rice farmers in optimizing agronomic practices to enhance yield efficiency under diverse environmental conditions.
