Abstract
Boron is the deficient micronutrient in the soils of Pakistan. Boron (B) deficiency is wide spread in rice growing areas of Pakistan. Low and very high soil B depress grain yield of cereals. A field experiment was conducted to determine the effect of different levels of B on the yield and yield components of rice genotypes. Two rice varieties viz., Khushboo-95 and Mehak were grown in field with four B levels 0, 0.5, 0.75 and 1.0 kg ha-1. The application of boron at 0.5, 0.75 and 1.0 kg ha-1 enhanced the paddy yield of Khushboo-95 by 9
