Description An experiment was conducted during 2013-14 at Regional Research Station, Karnal of CCS Haryana
Agricultural University to study the effect of different applied nutrients on cane yield, yield parameters
and juice quality of sugarcane (Saccharum spp. hybrid). The experiment comprised of 12 treatments
viz. T1: Control (No fertilizer), T2: N (@ 150 kg N ha-1), T3: N+P (@ 50 kg P2O5 ha-1), T4: N+P+K (@
50 kg K2O ha-1), T5: N+P+K+S (@ 40 kg S ha-1), T6: N+P+K+ Zn (@ 25 kg ZnSO4 ha-1), T7:
N+P+K+Fe (three foliar spray of 1 % FeSO4) , T8: N+P+K+Mn (three foliar spray of 0.5 % MnSO4),
T9: N+P+K+S+Zn, T10: N+P+K+S+Zn+Fe, T11: N+P+K+S+Zn+Fe+Mn and T12: Soil test based
fertilizer application. The design of the plot was randomized block design (RBD). Sugarcane yield,
yield parameters (cane girth, cane height (cm), number of internodes/plant and NMC 000 ha-1) and
juice quality parameters (extraction %, brix %, sucrose %, purity % and CCS %), were found
significantly affected by the treatments. The application of N over control (45.61 t ha-1), NP over N
alone (62.83 t ha-1), NPK over NP (69.97 t ha-1), and NPKS over NPK (75.16 t ha-1) significantly
increased cane yield. The application of N over control, NP over N, NPK over NP, and NPKS over
NPK showed 37.7 %, 11.4 %, 7.4 % and 2.4 % increase in cane yield. The application of N over
control (4.26 t ha-1), NP over N alone (6.21 t ha-1), NPK over NP (7.01 t ha-1) and NPKS over NPK
(7.98 t ha-1) significantly increased sugar yield. The application of NPK plus individual micronutrients
(Fe or Mn or Zn) treatments were at par with NPK treatment in cane yield parameters and sugar yield.
The application of particular nutrient in the soil increased its availability in the soil. Similarly the
concentration of particular nutrient in the index leaf was more where that nutrient was applied through
soil or through foliar application. The application of N over control, NP over N alone, NPK over NP,
and NPKS over NPK significantly increased farmer’s profit even after additional costs of inputs. The
application of macronutrients (N, P, K and S) and micronutrients (Fe, Mn and Zn) in combination
produced maximum gross returns of cane yield (2,08,832 Rs., B:C = 1.55) and is almost double as
compared to the control (1,14,492 Rs., B:C = 0.94). Same combination produced maximum sugar yield
and gross returns of sugar yield (3,38,520 Rs., B:C = 1.37) and is more than double as compared to the
control (1,44,675 Rs., B:C = 0.94).
