Abstract

An experiment was conducted to study the effect of nitrogen levels [Control, 100% recommended dose of nitrogen (RDN) through inorganic source (IS), 25% RDN (IS) + 25% RDN through organic source (OS), 50% RDN (IS) + 25% RDN (OS) and 75% RDN (IS) + 25% RDN (OS)] and zinc levels (2.5, 5.0 and 7.5 kg ha-1) on growth and yield of basmati rice. Growth, yield attributes and yield were highest with nitrogen level of 75% RDN (IS) + 25% RDN (OS) followed by 100% RDN (IS). Zinc level 5.0 kg ha-1 has produced maximum growth, yield attributes and yield. Grain yield obtained by combination of 75% RDN (IS) + 25% RDN (OS) along with 5.0 kg ha-1 Zn registered 2109.64 kg more yield than combination of control and 2.5 kg ha-1 Zn. 75% RDN (IS) + 25% RDN (OS) along with 5.0 kg ha-1 Zn has enhanced the growth and productivity of basmati rice.
