Abstract:

Field experiment was conducted during summer, 2018 to determine the influence of LAI on yield maximisation in finger millet genotypes by varying plant densities. Maximum grain yield was obtained at the plant density of 44.4 to 66.6 hills m-2 but above or below. The source size (LAI) and source activity (photosynthetic rate) were not the limitations for yield maximisation under optimal irrigation and; LAI of 6.5 to 7.0 was optimum for maximum finger millet yield especially in variety, GPU-28. The sink traits, namely productive tillers per m-2 and mean ear weight were compensated to each other (r = -0.967***). The plant density of 44.4 hills m-2 (22.5 cm x 10 cm) could be optimum for irrigated finger millet. Further yield enhancement could be possible by increasing productive tillers (up to 5.0 per hill) with plant density of 44.4 hills m-2 varying spacing to 30.0 cm x 7.5 cm.
