Yield optimization in pearl millet and sorghum under different crop techniques and agro-chemicals

Between 2011 and 2012, yield optimization in the pearl millet and sorghum was tested with seven treatment combinations of two spacing and foliar spray of agro-chemicals at Keshwana, Jalore (Rajasthan). Treatments included sowing at 30 cm and 60 cm row spacing, dust mulch at moisture stress stage and foliar spray of two agro-chemicals viz., 0.2% K₂SO₄ + 1000 ppm thiourea and 0.2% K₂SO₄ + 100 ppm ascorbic acid at grain development stage. Seed yield among of pearl millet and sorghum ranged between 27.75 - 32.66 and 13.23 - 16.54 q ha⁻¹ respectively. Treatment procedure of 60 cm row spacing and foliar spray of 0.2% K₂SO₄ + 100 ppm ascorbic acid at grain development stage provided maximum yield enhancement of 17.65% in pearl millet and 25.01% in sorghum over traditional practice with the highest B:C ratio of 5.62 and 4.06 respectively
