Abstract :

Field experiment was conducted during Kharif 2014 at College farm, Professor Jayashankar Telangana State Agricultural University, Rajendranagar, Hyderabad to study the yield parameters and yield of quality protein maize (QPM) as influenced by sulphur levels and method of application. The experiment was conducted in sandy loam by adopting factorial randomised block design (FRBD) with three replication and eight treatment combinations. The experiment was carried out with four sulphur levels (10 kg ha–1, 20 kg ha–1, 30 kg ha–1 and 40 kg ha–1) and two method of sulphur application (M1: 100% basal as single dose; M2: two split applications:– 50% each at basal and knee heigh stage). Among four sulphur levels 40 kg S ha–1 had resulted in higher cob length, cob girth, no. of grains per cob, test weight, grain and stover yield. Similarly, between the two method of application– M2, split application of sulphur at basal and knee heigh stage shown maximum cob length, cob girth, no of grains per cob, test weight, grain and stover yield compared with basal application of sulphur (M1).
