Influence of System of Crop Intensification Practices on Yield and Nutrient Uptake in Greengram (Vigna radiata (L.) Wilczek)

Abstract

Field experiments were conducted at Tamil Nadu Agricultural University, Coimbatore, during kharif and rabi seasons, 2010-11 to evaluate the influence of System of Crop Intensification (SCI) practices on greengram. The experiment consisted of nine treatments, viz., T 1 - Single seedling hill -1 at 20 x 20 cm, T 2 - Single seedling hill -1 at 25 x 25 cm, T 3 - Single seedling hill -1 at 30 x 30 cm, T 4 - Single seedling hill -1 at 40 x 40 cm, T 5 - Double seedlings hill-1 at 20 x 20 cm, T 6 - Double seedlings hill -1 at 25 x 25 cm, T 7 - Double seedlings hill -1 at 30 x 30 cm, T 8 - Double seedlings hill -1 at 40 x 40 cm and T 9 - Control (30 x 10 cm at two seedlings hill -1 ). The experiment was laid out in Randomized Complete Block Design with three replications. The results revealed that single seedling hill -1 maintained at 25 x 25 cm (T 2 ) registered significantly higher grain yield (1408 kg ha -1 ) and it was on par with double seedlings at 30 x 30 cm spacing (1323 kg ha -1 ) and double seedlings maintained at 20 x 20 cm spacing (1309 kg ha -1 ). The maximum N, P and K uptake was noticed with double seedlings hill -1 planted at a spacing of 30 x 10 cm (control). Available N and P status of the soil was the highest with single seedling maintained at 40 x 40 cm spacing (T4 ).
