Response of rabi maize (Zea mays L.) to fertilizer application and organic liquid spray under South Gujarat condition

Abstract

A field experiment was carried out at College Farm, Navsari Agricultural University, Navsari on clayey soils during rabi season of 2017-18 to study the “Response of rabi maize (Zea mays L.) to fertilizer application and organic liquid spray under south Gujarat condition”. The experiment comprising of twelve treatment combinations and it is randomized three times. Recommended dose of fertilizer recorded significantly higher growth and yield attributes viz., plant height, dry matter accumulation/plant, number of leaves/plant, leaf area/plant, number of cobs/plant, number of grains/cob, cob length and girth, cob weight, test weight, shelling% as well as yields of rabi maize, but it remained at par with treatment 75% RDF. Application of 2% foliar spray of banana pseudo stem enrich sap recorded significantly higher growth as well and yield attributing characters and yields of rabi maize. Most of all the growth attributes, yield attributes and yields of maize recorded significantly higher under two sprays of organic liquid at 30 and 40 DAS over one spray of organic liquid at 30 DAS.
