CONSERVATION OF MOISTURE THROUGH AMENDMENTS UNDER VARYING IRRIGATION REGIMES ON SUGARCANE (SACCHARUM-OFFICINARUM)

Two field trials were conducted during the main season of 1987-88 and 1988-89 to study the effect of different irrigation regimes, applicati on of amendments, and their interaction oil moisture conservation, can e growth and yield of sugarcane (Saccharum officinarum L.). Irrespecti ve of irrigation regimes, basal incorporation of coirwaste at 25 tonne s/ha recorded higher cane yield of 134.3 tonnes/ha owing to more moist ure-retentive capacity than other amendments. The cane yield was also higher in jalashakti treatment (124.6 tonnes/ha) than farmyard manure (114 tonnes/ha) and pressmud (119.9 tonnes/ha). Application of coirwas te and jalashakti in treatments where water was applied once in 19 day s resulted in the net profits of Rs 21,674 and Rs 16,248 respectively.
