Effect of irrigation frequencies and mulches on the yield of summer cholam (Sorghum vulgare Pers.)
(Regional Post Graduate Training Centre, Agricultural College and Research Institute, Coimbatore, 1963) Abraham Jacob, T; KAU; Mariakulandai, A
An experiment was conducted to find out the relative efficiency of three different moisture regimes, due to irrigation frequencies, at seven, fourteen and twenty one days, and three types of mulching viz., dust, trash and polythene mulches. The modifying effect of the mulches on soil conditions and crop growth was studied, to assess whether irrigation requirements could be reduced without deterioration in yield. The moisture regime had significantly increased the height of plants and length of earheads, while it had no influence on other yield attributes. Length of earhead, breadth of earhead and diameter of peduncle were significantly increased by the mulches.
