SUMMARY
A field experiment was conducted during kharif 2011, 2012 and 2013 for consecutive three years
at Agricultural Research Station, S. K. Rajasthan Agricultural University, Bikaner to study the effect of
planting material and crop geometry on growth, yield and quality of sewan grass. The experiment consisted of eight treatment combinations with planting material and crop geometry viz., seed sowing+100 x 75 cm spacing, seed sowing+100 x 50 cm spacing, seed sowing+75 x 50 cm spacing, seed sowing+50 x 50 cm spacing, root slip sowing+100 x 75 cm spacing, root slip sowing+100 x 50 cm spacing, root slip sowing+75 x 50 cm spacing and root slip sowing+50 x 50 cm spacing. The experiment was laid out in randomized block design and replicated thrice. Results showed that maximum plant height (79 cm), total tillers/m row length (83), number of spikes/plant (49.71) and seed yield (14.32 q/ha) were recorded with seed sowing+100 x 50 cm spacing, whereas highest grass yield (54.62 q/ha) was recorded with seed sowing+75 x 50 cm spacing. Maximum values of sustainability yield index were recorded with root slip sowing+50 x 50 cm spacing both for grass (80.98%) and seed (27.17%) yield of sewan grass. Planting material and crop geometry did not influence quality parameters viz., crude protein, crude fibre and total ash content of sewan.
Key words:Crop geometry, crude protein, grass yield, seed and root slip sowing, seed yield, sustainability yield index
