Effect of QPM hybrids (Zea mays L.) on nutrient uptake and quality under different plant population and nutrient management practices

Abstract

A field experiment was conducted at Udaipur during Kharif season of 2016 to study the effect of varying plant population and nutrient management on the nutrient uptake and quality of QPM hybrids. Results revealed that highest nitrogen and phosphorus content and grain and Stover their uptake was found with the application of STCR which was followed by SSNM and RDF. N and P uptake in grain and total uptake of N and P was found significantly higher in HQPM-5 over PQMH-1. Hybrid HQPM-5, 1, 00, 000 plants ha-1 and application of STCR was found better in terms of chlorophyll content. Protein content was found highest with application of STCR over SSNM and RDF.
