Effect of System of Crop Intensification Practices on Productivity in Greengram (Vigna radiata (L.) Wilczek)
Abstract:
Field experiment was conducted during three consecutive seasons (Kharif 2010, 2011 and 2012) at Wetland farms of Tamil Nadu Agricultural University, Coimbatore, to evaluate the System of Crop Intensification (SCI) practices on the growth and yield of Greengram. The experiment consisted of six treatments in the combination of maintaining two seedlings (one and two) and three spacing levels (20 × 20 cm, 25 × 25 cm, and 30 × 10 cm) which were tested in the Randomized Complete Block Design with four replications. Three seasons’ pooled data revealed that the maximum growth characters such as plant height, LAI and DMP at 20 DAS, 40 DAS and at harvest stages were recorded in control (30 × 10 cm with two seedlings). The yield attributes such as number of clusters hill-1, number of pods hill-1 and number of seeds pod-1 were higher in the single or the double seedlings maintained at 25 × 25 cm spacing level. Significantly higher grain yield (1091and 1060 kg ha-1) was recorded in 25 × 25 cm spacing level with both the single and the double seedling maintained plots respectively, when compared to the other combinations. The same trend was noted with Harvest index too. Haulm yield also varied significantly and a maximum of 1486 kg ha-1 was observed in the control (Double seedlings sown at 30 × 10 cm spacing level).
