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.

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