Effect of micro-irrigation and fertigation on growth parameter and fruit yield of acid lime

Abstract

The experiment was laid out in factorial randomized block design comprised of three levels of irrigation i.e. 100, 90 and 80 per cent micro-irrigation of Evp and three levels of fertigation i.e. 100, 80 and 60 per cent RDF with nine treatment combinations replicated thrice to study the effect of micro-irrigation and fertigation on plant growth parameters. The plant growth in respect of plant height and plant spread was found maximum in I1 (100% micro irrigation at Evp) and in F1 (100% RDF through fertigation) individually which were at par with I2 (90% micro irrigation at Evp) and F2 (80% RDF fertigation) except increment in shoot length. The treatment combinations of irrigation and fertigation were non-significant on these parameters. The significantly highest number of fruits in hasta bahar were produced in the irrigation level I3 (676.6); fertigation level F1 (688.6) and in combination treatment I3F1 (734.2) which were at par with I2 (664.2); F2 (671.9) and I3F2 (719.5) and I2F1 (710.5), respectively during pooled results.
