ABSTRACT
The field experiment was conducted during the kharif 2012 at Agricultural college farm, Raichur to study the effect of soil test based nutrient management approaches on growth, yield and yield components of maize (Zea mays L.). The results revealed that, the yield and yield components of maize were influenced favourably with application of fertilizer by SSNM for targeted yield 8 t ha-1 recorded significantly highest grain yield (77.40 q ha-1), stover yield (107.6 q ha-1), ), number of grains per cob (701.82), number of grains per row (38.94), number of rows per cob (18.17), cob length (20.81 cm), The growth parameters of maize were also influenced favourably with application of fertilizer by SSNM for targeted yield 8 t ha-1, Dry matter production (376.67 g plant-1), plant height (201.83 cm), leaf area per plant (2527.74 cm2) and leaf area index (LAI) (1.40) over STCR for targeted yield 8 t ha-1 and RDF 150,75,40 kg NPK ha-1.
Key words :
Growth & yield parameters, Maize, Nutrient management, SSNM, STCR, RDF, Zea mays.
