Abstract:
A field experiment was
conducted under semi-arid climatic conditions to evaluate the response
of pressmud in combination with inorganic fertilizers and alone (only
inorganic fertilizers) on the yield and sugarcane quality parameters
besides a value-added product (locally called Gur). It is obvious from
the results that inorganic fertilizer use (T2) has increased
the tillers per plant, number of 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 of pressmud was applied in integration with inorganic
fertilizers (in T3), it increased total soluble solids,
sucrose, purity, CSS and sugar recovery of juice by 7.83 %, 10.42 %,
2.80 %, 12.06 %, and 12.07 %, over the control (T1). The
studies concluded that higher doses of mineral fertilizers increased gur
% juice but it did not improve gur quality as done by higher doses of
organic manures. Soil properties were also investigated before and after
crop harvest. Maximum fertilizer use efficiency (124.29) was recorded in
T2.
