Effect of micro-irrigation and nutrient management on quality parameters and economics of potato
Author(s): Shakshi Mankotia and Sanjay Sharma
Abstract: The present study was conducted at experimental farm of CSK HPKV, Palampur, with the objective of evaluating the effects of micro-irrigation and nutrient management on quality and economics of drip based irrigation and fertigation. Ten treatments comprised three drip irrigation levels viz., 0.4 PE, 0.6 PE and 0.8 PE corresponding to 40, 60 and 80 per cent of cumulative pan evaporation, respectively, three fertigation levels viz., 50% RDF, 75% RDF and 100% RDF equivalent to 50, 75 and 100 per cent of recommended dose of NPK, respectively and RP i.e. recommended practice (recommended dose of fertilizers was applied through conventional methods and 6 flood irrigations of 50 mm). Fertigation level of 75% RDF was statistically at par with 100% RDF but significantly better than 50% RDF with respect to quality parameters. Drip irrigation and fertigation was better than the recommended practice as combination of irrigation level of 0.6 PE and 75% RDF recorded better quality parameters. Also, the highest gross return (Rs. 285200 ha-1), net return (Rs. 153949 ha-1) and B:C ratio (2.17) were obtained by applying drip irrigation @ 60 per cent of cumulative pan evaporation (0.6 PE) and 75 per cent recommended dose of NPK (75% RDF).
