Effect of Zn, Fe and FYM application on growth, yield and nutrient content of rice

A field experiment was carried out at Banaras Hindu University, Varanasi during wet season, 2006-07 and 2007-08. Testing variables consisted of two varieties i.e. NDR-359 and HUBR 2-1, two sources of fertilizer application i.e. 100% recommended dose of fertilizer (RFD) of NPK through inorganic source and 75% RFD through inorganic and rest 25% through FYM. Two micronutrients, Zn and Fe through Zn-EDTA and Fe-EDTA were tested in different combinations either on soil or as foliar application or both @ 0.5 and 1.0 Kg ha-1. Amongst varieties, var. NDR-359 recorded significantly higher growth, yield and NPK content of grain than HUBR 2-1, while Zn and Fe content were significantly increased in HUBR 2-1. Fertilizer source as application of 75% RFD through
inorganic and rest through FYM recoded significantly higher growth, yield and N, P, K, Zn and Fe content of grain than 100% RFD through inorganic source. Among the different micronutrient treatments, soil application of Zn-EDTA @ 1 Kg ha-1 recorded significantly higher Zn content in grain, whereas application of Fe-EDTA @ 0.5 Kg ha-1 recorded significantly higher Fe content in grain as compared to other micronutrient treatments.
