Effect of Varying Doses of Lime on Yield and Attributes of Maize in Mizoram

A study was carried out on varying doses of lime to maize in an acid soil of Mizoram to determine the effect of lime on yield and its attributes in maize. Lime treatments ranged from 0, 1, 1.5 and 2 t/ha. The maize variety RCM 1-1 was tested with or without added lime. Trials showed lime increased pH increased yield up to its highest dose of application. However, it did not significantly increase yield. Plant height in maize ranged from 170 cm when no lime (control) to 241.75 cm with 2t/ha of lime addition. Sixteen per cent, 35 per cent and 43 per cent increase in yield was observed at different levels of lime over no lime application. Almost 19 per cent, 35 per cent and 43 per cent increase in no. of grains/cob was recorded at different levels of lime over no lime use.
