Abstract:
A field experiment was conducted on productivity and nutrient uptake of soybean and millets in intercropping systems during kharif 2016 at Agricultural Research Station Bailhongal, Belagavi district (Karnataka). The experiment was laid out in Randomized Block Design with three replications. Treatment details T₁ - Soybean + foxtail millet (2:1), T₂ - Soybean + foxtail millet (4:2), T₃ - Soybean + finger millet (2:1), T₄ - Soybean + finger millet (4:2), T₅ - Soybean + little millet (2:1), T₆ - Soybean + little millet (4:2), T₇ - Sole crop of soybean, T₈ - Sole crop of foxtail millet, T₉ - Sole crop of finger millet and T₁₀ - Sole crop of little millet. The results concluded that, sole crop of soybean recorded significantly higher grain yield (2,255 kg ha^-1) as compared to any intercropping systems. It was on par with 4:2 row ratio of soybean + foxtail millet (1,697 kg ha^-1). Further, Sole foxtail millet recorded significantly higher grain yield (1,901 kg ha^-1) as compared to their yield in intercropping systems. Among the intercropping systems, higher grain yield of millet was recorded in 4:2 row ratio of soybean + foxtail millet (1,429 kg ha^-1) and it was on par with 2:1 row ratio of soybean + foxtail millet (1,419 kg ha^-1). With respect to nutrient uptake, 4:2 row ratio of soybean + millet recorded higher uptake of nitrogen, phosphorous, potassium and sulphur in soybean as compared to 2:1 row ratio.
