System of Crop Intensification (SCI) Techniques on Yield and Economics of Greengram
Field experiment was conducted at Tamil Nadu Agricultural University, Coimbatore, during Rabi (OctJan) season, 2010 2011 to evaluate the influence of System of Crop Intensification (SCI) practices in greengram. The experiment was laid out in Randomized complete block design comprised of nine treatments. The treatments were replicated thrice. Yield attributes like number of clusters hill 1 (7.67) and number of pods hill 1 (38.00) was significantly higher with double seedlings hill 1 maintained at 40 x 40 cm planting geometry (T8) than other levels. Whereas, pod length and 100 grain weight were not altered due to SCI practices. Double seedling hill 1 maintained at 20 x 20 cm spacing (T5) registered significantly higher grain yield (1263 kg ha 1 and it was on par with single seedling hill 1 maintained at 25 x 25 cm spacing (1207 kg ha 1 single seedling hill 1 with 25 x 25 cm spacing (1207 kg ha 1 and double seedlings with 30 x 30 cm (1117 kg ha 1 Haulm yield was higher under double seedlings hill 1 with 30 x 10 cm spacing (2746 kg ha 1 The highest net return 16371) and B: C ratio (1.76) were obtained with double seedlings hill 1 maintained at 20x 20 cm spacing (T5) Hence, it is concluded that under SCI in greengram (variety CO 6) raised at 20 x 20 cm spacing with double seedlings proved to be a better option for getting higher productivity and profit under garden land condition of Western zone of Tamil Nadu.
