The present investigation entitled, “Studies on Effect of Organic Nutrient Sources on nutrient uptake and different soil properties in onion (Allium cepa L.)” was carried out at Organic Block of Experimental Farm, Department of Vegetable Science, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan, (HP) in the Rabi season 2016-2017 with the aim to understand the effect of organic nutrient sources on nutrient uptake and different soil properties in onion cv. ‘Palam Lohit’. The experiment was laid in Randomized Complete Block Design (Factorial) with three replications comprising of ten treatments. Organic manures with five levels [M0 (No Manure), M1 (FYM @ 25 t ha-1), M2 (Vermicompost @ 8 t ha-1), M3 (FYM 50 % + VC 50 %), M4 (FYM 75 % + VC 25 %)] was the first factor and application of liquid manure with two level [L0 (No liquid manure), L1 (Liquid manure i.e. Jeevamrut)] was the second factor. The results revealed that treatment T8 [Vermicompost @ 8 t ha-1 + Jeevamrut (Drenching, 5%)] recorded maximum N, P, K content in soil (336.16, 62.24 and 362.64 kg ha-1) and N, P, K uptake by plant (151.93, 28.86 and 57.19 kg ha-1). The same treatment also resulted in highest net return (Rs. 7, 08,895.37) and B:C ratio (4.74). Hence, it can be concluded that application of [Vermicompost @ 8 t ha-1 + Jeevamrut (Drenching, 5%)] optimized the nutrient requirement of the onion crop for better yield with maximum return and advantage of environment protection and soil health.
