Effect of improved agronomic practices on yield of processable cultivar of potato (Solanumtuberosum L.) cv. Lady rosetta

Abstract

The present investigation was carried out to study the effect of Improved Agronomic Practices on Yield of Processable Cultivar of Potato (Solanumtuberosum L.) cv. Lady rosetta at student research farm, Department of Agriculture, Khalsa College Amritsar. The soil of the experimental field had sandy loam texture with normal pH and electrical conductivity, low in organic carbon and available nitrogen, medium in available Phosphorus and high available Potassium. The filed was laid out in factorial randomized complete block design with three replications. There were total two factors Factor A was method of sowing and Factor B was method of irrigation. Method of sowing comprises 6 treatments B1: 60cm bed, B2: 75cm bed, B3: 90cm bed single row, B4: 90cm bed double row, B5: 105cm bed double row, B6: 105cm bed triple row whereas irrigation methods comprises drip irrigation: I1 and furrow irrigation: I2. The results revealed that growth parameters like plant height, number of stems per hill, leaf area index and dry matter accumulation were recorded maximum in 60cm bed sowing. Maximum yield was obtained in 60cm bed (246.3 qha-1) whereas in irrigation system drip produced maximum yield (236.1qha-1). Maximum yield through interaction was found in drip irrigated 105 cm triple row bed.
