Abstract

The effect of micronutrients on the yield and uptake of micronutrients in paddy variety IR-8 was studied at four levels of fertility in pot culture. Total dry matter yield increased with increasing levels of fertility. The interaction between fertility levels and micronutrient treatments had significant effect on dry matter yield. At higher levels of fertility application of manganese, copper, molybdenum and mixture of micronutrients generally increased the dry matter yield, whereas at lower levels their effect was not apparent.
