Abstract:
Half of the world's population (approximately more than 3.5 billion people) depends on rice for their 20% daily energy requirements. Rice crop production is under threat for many reasons, including but not limited to micronutrients deficiencies especially of Boron. Most of the rice based cropping systems are facing Boron deficiency when cultivated on low soil organic matter and high pH. Basic soils usually have low Boron and inadequate supply of Boron fertilizer. This results in insufficient availability, uptake and accumulation of Boron into grains. A field experiment was conducted to elucidate the effect of Boron alone and with fulvic acid on morpho-physiological and yield contributing parameters of rice. Experiment was laid down in Randomized Complete Block design with two replications. Total experimental area was (13×24) ft., upon which foliar application of Boron and Boron+FA was applied at tillering and panicle formation stage with recommended doses of fertilizer. The results showed that Boron application substantially increases paddy yield, improves nutrient uptake, 35.5% number of tillers, 38.1% number of fertile florets per panicle, 37.9% 1000 grain weight and 19.31% leaf Boron content in fine grain rice cultivars. In conclusion, Boron supplement, especially foliar treatment enhances grain weight, yield, improves rice quality and reduces panicle sterility.
