Abstract

An investigation was conducted in the polyhouse at experimental field of the Division of Vegetable Science, Sher-e-Kashmir University of Agricultural Sciences and Technology of Kashmir (SKUAST-Kashmir) during Kharif season 2013-14 to find out the most suitable organic source and pruning pattern for optimum growth, yield and quality of sweet pepper in Kashmir valley against four different nutrient treatments (S1 : Farmyard manure @ 2.5 kg m-2 , S2: Vermicompost @ 0.5 kg m-2 , S3: Sheep manure @ 1.65 kg m-2 and S4: Recommended fertilizer dose (20 t FYM + NPK @ 120:90:60 kg ha-1) under two pruning levels P1 : One shoot and P2: three shoot. The experiment was laid out in a Complete Randomized Block Design (CRBD) with three replications. Data with regards to main effect revealed that organic manures through vermicompost (S2) was found as a best source for highest available Nitrogen, potassium and organic carbon (%). Application of Vermicompost resulted also in highest available Phosphorus. The highest soil pH and EC was recorded by application of recommended dose of fertilizers while the lowest pH was recorded by the application of sheep manure. With regards to relative economics of different treatments the highest net returns (22,324/-) and benefit cost ratio (2.87) was found in vermicompost with plants pruned to three shoots.
