Abstract:
A field experiment was conducted to study the feasibility of customized fertilizers for sustainable productivity of rice at Agronomy Research Farm at Narendra Deva University of Agriculture and Technology, Faizabad during Kharif 2014 and 2015. The treatment 3; application of Soil Test Based Recommendation (N-140:P2O5-60: K2O-30: S-30: Zn-5:B-2 kg ha^-1) was found maximum plant height (cm), number of tillers m^-2, number of effective tillers m^-2 which was at par with (Indo Gulf) and (Tata Chemical Limited) and significantly superior over control, RDF and Farmer’s’ practices. The highest grain and straw yield and nutrients uptake of nitrogen, phosphorus, potassium, sulphur, zinc and boron of rice was recorded with T₃ (Soil test based recommendation) was significantly superior over the control (18.31 q ha^-1), RDF (43.42 q ha^-1) and Farmers’ practices (28.36 q ha^-1) and statically at par with Vardan (Indo gulf) (48.33 q ha^-1) and Paras (TCL) (47.50 q ha^-1). The highest net return (Rs.32204 and Rs.34968 ha^-1) and B:C (0.74 and 0.84) during 2014 and 2015, respectively were also obtained due to application of soil test based recommendation which was followed by application of Indo Gulf- Customized Fertilizers- Vardan and TCL- Customized fertilizers-Paras.
