ABSTRACT

A field experiment was conducted during rabi, 2016 at S.V. Agricultural College Farm, Tirupati (dry land or wet land) to study the effect of varieties and crop geometry on the growth parameters and yield attributes of dual purpose sorghum. The results revealed that M 35-1 was found to the most promising genotype in obtaining higher plant height (179.4 cm), leaf area index (18.8), dry matter production (5596.0 kg ha-1) and highest light intensity(87.4%) was recorded with CSV- 15. Crop geom-etry of 60 cm x 10 cm recorded maximum plant height (175.5 cm), leaf area index (19.45) and dry matter production (5715.5 kg ha-1) and light intensity (86.9 %) followed by 45 cm x 15 cm spacing.
