Abstract:

A field experiment was conducted to study the effect of different levels and two methods of sulphur application on growth parameters of quality protein maize (QPM) at College farm, Professor Jayashankar Telangana State Agricultural University, Hyderabad, during 2014-2015 using factorial randomized block design (FRBD) with three replications and eight combinations as four different sulphur levels  (10 kg ha-1, 20 kg ha-1, 30 kg ha-1 and 40 kg ha-1) and two methods of sulphur application (M1: 100% basal as single dose; M2: Two split applications: 50% each at basal and knee heigh stage). Maximum plant height, LAI and Dry matter production was obtained with 40 kg S ha-1 as compared to 30 kg S ha-1, 20 kg S ha-1  and 10 kg S ha-1. Similarly, two methods of application split application of sulphur at basal and knee heigh stage shown maximum plant height, LAI and Dry matter production. Almost all the treatments have significantly affected in 60 DAS, 90 DAS and harvest stage of plant height, LAI, Dry matter production but 30 DAS is shown no significant. Plant population and days to 50% flowering has shown no significant effect. Application of sulphur at 40 kg ha-1 along with split method of application can be recommended for sustaining productivity and profitability in quality protein maize. The right quantity and application at correct stage of the plant is important for growth and development of QPM.


Keywords: Growth, LAI, Dry matter production, Sulphur levels, Application method, Quality Protein Maize.
