Effect of Zinc and Boron Fertilizer Application on Uptake of Some Micronutrients into Grain of Rice Varieties

4 Abstract: Field experiment was conducted to assess the response of five rice varieties; IR6, IR8, DR92, DR84 and Shahkaar at different treatments of fertilizers. Higher uptakes; 4.08± 0.37, 4.72±0.45, 3.88±0.24, 2.47±0.09, 4.08±0.14 µg g of boron; 15.08±0.83, 12.29±0.05, 13.35±0.57, 11.67±0.3, 15.65±0.21 µg g of Zn and 36.98±0.5, 11 Shahkaar, respectively were found at T2. Micronutrients B, Zn, Cu, Fe uptakes into grain of the varieties; IR8, DR92, IR6 and DR83 significantly (P< 0.05) increased at T1 and T2. Similar increasing trend for Mn uptake in all other varieties than IR8 and DR83 was found. It could be concluded that application of Zn and B at the doze 10 and 2 Kgha in addition to recommended doses of N and P may be applied to rice crops for better 1 nutritional contents within grains.
