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 ).
Key words : Greengram, system of crop intensification, spacing, number of seedlings hill -1 , grain yield,
nutrient uptake, soil available nutrients.
