Growth, yield and economics of irrigated finger millet as influenced by system of finger millet intensification (SFI) practices in north eastern zone of Tamil Nadu

Abstract

Field experiment was conducted during Kharif, 2018 at Centre of Excellence in Millets, Athiyandal, Thiruvannamalai to assess the System of Finger millet Intensification (SFI) for north eastern zone of Tamil Nadu. Results revealed that growth parameters such as DMP, LAI and number of tillers were more under 22.5 x 10 cm spacing with two hand weeding’s at 15 and 30 DAT. While the yield attributes such as number of productive tillers, number of ear heads hill-1 and number of fingers earhead-1 were higher under 30 x 10 cm spacing with two hand weeding’s at 15 and 30 DAT. The maximum grain yield, straw yield, HI, gross return, net return was also recorded under 30 x 10 cm spacing with two hand weeding’s at 15 and 30 DAT. The highest B:C ratio was recorded under 30 x 10 cm with one hand weeding at 15 DAT + one mechanical weeding at 30 DAT.
