To study the effect of organic manures on nutrient uptake & economics of mustard crop

Abstract

A field experiment was conducted at Agronomy Research Farm of Narendra Deva University of Agriculture and Technology, Ayodhya (Uttar Pradesh) during the Rabi season of 2012-13 “To Study the Effect of Organic Manures on Nutrient Uptake (Nitrogen, Phosphorus & Potassium) & Economics Of Mustard Crop. The experiment comprised of six treatments viz. one 100% fertilizer, one integrated (FYM+Fertilizer) and four 100% organic consisting various combinations of organic sources (FYM, Vermicompost, Neemcake, PSB, Azotobacter), tested in Randomized Block Design and replications three times. The basic information on the physico-chemical properties of the soil indicated that the soil of the experimental field was classified as silty loam which was low in organic carbon, nitrogen and phosphorus and medium in potassium. The crop recorded normal recommended cultural practices and plant protection measures. Results revealed that all the growth, nutrient uptake of nitrogen, phosphorus & potassium, yield attributes and quality increased significantly under the integrated treatment (FYM+FERETILIZER). The growth characters viz., plant height, leaf area index, dry matter accumulation and number of branches per plant and yield attributes like number of siliquae per plant, number of seed per siliqua, length of siliqua (cm), 1000 seed weight(g), biological yield, seed yield, stover yield(q ha-1), harvest index(%) and NPK uptake of mustard crop. On the basis of economics of different treatment, the maximum gross returns (Rs. 78598.00 per ha), net returns (Rs 59067.00 per ha) and Benefit:Cost ratio (3.02) was recorded under integrated treatment (FYM + fertilizer) for mustard crop.
