Plant growth parameters and yield as influenced by integrated nutrient management in sweet corn

Abstract

A field experiment was conducted during kharif season of 2019 at Department of Agronomy College of Agriculture, Latur to study the effect of integrated nutrient management in sweet corn (Zea mays L. var. saccharata sturt).The objective of experiment was to study the effect of integrated nutrient management on sweet corn. The experiment was laid out in randomized block design with seven treatments and replicated thrice. Treatments were 100% RDF, 100% RDF + FYM @ 5 t ha-1, 75% RDF + FYM @ 5 t ha-1, 100% RDF + Vermicompost @ 2.5 t ha-1, 75% RDF + Vermicompost @ 2.5 t ha-1, 100% RDF + FYM @ 5 t ha-1 + Vermicompost @ 1.25 t ha-1+ Azospirillum and 75% RDF + FYM @ 5 t ha-1 + Vermicompost @ 1.25 t ha-1 + Azospirillum. The result revealed that the application of 100% RDF + FYM @ 5 t ha-1 + Vermicompost @ 1.25 t ha-1+Azospirillum increased the growth characters viz., plant height (200 cm), number of functional leaves (17.60), dry matter accumulation (128.33 g), leaf area (76.35 dm2).Green cob yield (10621 Kg ha-1) and green fodder yield (21824 Kg ha-1) of sweet corn were highest with the application of 100% RDF + FYM @ 5 t ha-1 + Vermicompost @ 1.25 t ha-1 + Azospirillum.
