ABSTRACT
Integrated use of organic and inorganic fertilizers produces economical and maximum possible yield on sustainable basis. A field experiment was conducted at National Tea and High Value Crops Research Institute (NTHRI) Shinkiari to investigate the effect of organic and inorganic fertilizers on soil properties and productivity of radish during rabi season 2021-2022. The experiment was laid out in randomized complete block design (RCBD) with three replications. There were ten treatments in the experiment including control, farmyard manure (FYM) and vermicompost (VC) applied with 30 – 22.5 – 15, 60 – 45 – 30, 90 – 67.5 – 45 and 120 – 90 – 60 kg ha-1N, P and K, respectively. All Phosphorus and Potassium were applied at sowing time while urea was added into splits i-e half at sowing and remaining half with first irrigation. Mino Early variety of radish was grown @10 kg ha-1. The Results showed that maximum radish fresh matter yield (28734 kg ha-1) with 88% increase, dry matter yield of 3518 kgha-1 with 79% increase and plant height of 76.3 cm with 57% increase and radish length of 39.7 cm with 48% increase over control were recorded in treatment where 90 – 67.5 – 45 N, P and K kg ha-1 levels were applied with vermicompost followed by the yield produced by 120 – 90 – 60 kg ha-1 levels. Soil organic matter content (1.37%) total N content (1126 mg kg-1) and AB-DTPA extractable P & K contents of 5.53 and 147 mg kg-1, respectively were maximum in treatment of 90 – 67.5 – 45 N, P and K kg ha-1 uptake of 100.3, 16.7 92.6 kg ha-1, N, P and K respectively were noted in the treatment of 90 – 67.5 – 45 N, P and K kg ha-1 levels added with VC, applied with VC. Results suggested that application of vermicompost @5t ha-1 with 90 – 67.5 – 45 N, P and K kg ha-1levels of N, P and K produced maximum radish yield and improved plants N, P and K uptake and is recommended under the prevailing conditions.
