Appraisal of pressmud and inorganic fertilizers on soil properties yield and sugarcane quality

摘要

A field experiment was conducted under semi-arid climatic conditions to evaluate the responseof pressmud in combination with inorganic fertilizers and alone (only inorganic fertilizers) on theyield and sugarcane quality parameters besides a value-added product (locally called Gur). It isobvious from the results that inorganic fertilizer use (T2) has increased the tillers per plant, numberof millable canes, stripped cane yield, sugar yield and juice present cane by 38.95 %, 38.66 %,51.96 %, 54.92 % and 21.9 5% respectively, over the control (T1). Similarly when higher dose ofpressmud was applied in integration with inorganic fertilizers (in T3), it increased total solublesolids, sucrose, purity, CSS and sugar recovery of juice by 7.83 %, 10.42 %, 2.80 %, 12.06 %, and12.07 %, over the control (T1). The studies concluded that higher doses of mineral fertilizersincreased gur % juice but it did not improve gur quality as done by higher doses of organicmanures. Soil properties were also investigated before and after crop harvest. Maximum fertilizeruse efficiency (124.29) was recorded in T2.
