Productivity and Quality of Maize (Zea mays L.) as influenced by Phospho Enriched Compost and Fertility Levels in Southern Plains of Rajasthan

Abstract

The investigation was carried out to study the effect of phospho enriched
compost and fertility levels on productivity and quality of maize (Zea mays L.) in
Typic Haplustepts soil of Sub-Humid Southern Hills and Aravalli Region of Rajasthan.
The experiment was undertaken during kharif 2018 and 2019 at Instructional Farm
(Agronomy), Rajasthan College of Agriculture, Udaipur (Rajasthan). The author evaluated
four levels of phospho enriched compost (PEC) i.e. control, PEC @ 2.0, 4.0 and 6.0 t ha -1
and four levels of fertility i.e. control, 50% RDF + foliar spray of Zn @ 0.5%, 75% RDF
+ foliar spray of Zn @ 0.5% and 100% RDF + foliar spray of Zn @ 0.5%. The increasing
levels of phospho enriched compost and fertility up to 6 t ha -1 and 100% RDF + foliar
spray of Zn @ 0.5%, respectively increased significantly the seed yield, stover yield
and protein content in seeds of maize. However, the combined application of phospho
enriched compost @ 6 t ha -1 and 100% RDF + foliar spray of Zn @ 0.5% was found to
record significantly higher seed and stover yield.
