Abstract

Field experiment was conducted during 1998-2000 on soil deficient in available boron (0.35 mg) kg') at Agricultural Research Station, Bhavanisagar to study the comparative efficacy of Agribor as a source of boron on dry matter production, yield attributes and yield of maize crop. Four levels of boron (0.5, 1.0, 1.5, 2.0 kg B ha) including foliar spray of 0.2% and 0.3% through two sources viz., borax (soil) and boric acid (foliar) [S,] and Agribor [S] were tried. A significant response was obtained to B application on dry matter production, yield attributes and yield of maize at the level of 2kg B ha' followed by 1.5 kg B ha'. Foliar application also significantly increased the yield of maize over control. On comparing the sources of boron, Agribor was found to be effective in influencing the yield of maize.

Keywords: Boron nutrition, dry matter production, yield attributes and yield of maize
