Abstract:
An experiment on Tomato (Lycopersicon esculentum L.) was conducted during Zaid season of 2020-21 and 2021-22, at Agriculture Research Farm, School of Agriculture Science & Technology, Sangam University, Bhilwara, Rajasthan (India) to understand the effect of integrated nutrient management at different doses combination on plant growth and yield of tomato variety Abhilash. The experiment was conducted in Randomized Block design. The nutrient sources applied were Biofertilizer [Phosphorus solubilizing bacteria (PSB) + Azotobector] @ 5 kg each per ha; Vermicompost (VC) @ 10 t/ha (100%); Farm Yard Manure (FYM) @ 25 t/ha (100%) and Poultry Manure (PM) @ 8 t/ha (100%). Under the present investigation 12 treatments were prepared with different combination doses of integrated nutrient management mentioned in and replicated thrice. Results evident that the maximum fruit yield per hectare was produced by T₁₁ [75% RDF + 25% organic (FYM + VC + PM)] (282.98 Qu. in first year and 292.20 Qu. in second year) over control T₁ (100% RDF) which produced 168.10 Qu. and 171.30 Qu. in both years respectively. The fruit yield noted under application of T₁₁ were significant and greater over control T₁. The minimum fruit yield of tomato was recorded in case of control i.e., 100% RDF applied, viz., 168.10 Qu. and 171.30 Qu. Per hectare in both years respectively. The maximum net profit Rs. 322596 and 356776 along with maximum C: B ratio 2.48 and 2.55 in both the years respectively in 2020-21 and 2021-22 was noted by the treatment T₁₁ i.e., application of 75% RDF + 25% organic (FYM + VC + PM). The minimum net profit was noted under T₆ i.e., 100% PM + Biofertilizer, Rs. 173627 with C: B ratio 1.84 in 2020-21; and Rs. 196610 with C: B ratio 1.97 in 2021-22. From the present investigation it was concluded that T₁₁ was found to be best among all treatment in terms of growth and yield of tomato i.e., plant height, stem diameter, number of branches, number of fruits, fruit diameter, fruit weight etc. It is concluded from the investigation that the treatment T₁₁ was found suitable for application in tomato cultivation.
