Fertilizer use efficiency FUE
5. Fertilizer use efficiency FUE
Fertilizer use efficiency was computed considering the fruit yield and total NPK applied per hectare by drip fertigation. Of course the doses in each levels under WSF and NF were similar 125, 100 and 75 levels but the forms of fertilizers applied were different. The total NPK nutrients supplied by fertigation both in WSF and NF was 330:266:990 1586 NPK Kgha at 100 dose F2 and 1982.5 kg at 125 dose and 1189.5 kg at 75 dose. Under this evaluation, in Ist crop, among the forms of fertilizers, WSF was significantly superior to NF with a mean higher FUE of 15.862 kg fruit kg nutrient 8.98 increase as compared to NF with 14.554 kg fruit kg nutrient. In both forms of fertilizers viz., WSF and NF, higher FUE was associated with lower fertigation dose of 75 as compared to 100 and 125 fertigation doses. This is exactly opposite trend of fruit yield obtained. Among fertigation levels, WSF at 75 dose has registered significantly higher FUE of 21.886 kg fruitkg nutrient applied as compared to NF at the same 75 dose 18.445 kg fruit kg nutrient. In both forms of fertilizers, fertigation at 125 dose has registered significantly lower mean FUE of 12.463 kg fruit kg nutrient as compared 14.837 and 18.323 kg fruit kg nutrient applied at 100 and 125 doses respectively. Similar to this finding, it is reported that the average NPK use efficiency was highest under schedule-I 40 NPK dose compared to higher fertigation doses in Thompson seedless grapes Jagdev Sharma et al. 2008. Among the drip irrigation levels, I1-drip at 100 IRc has registered significantly higher FUE of 16.572 kg fruitkg nutrient to other levels 15.175 and 13.875 kg fruit kg nutrient at 75 and 50 IRc respectively. Similar trend was recorded in 2 nd and 3 rd crops. The relationship between fruit yield, fertilizer use efficiency and fertigation levels with WSF and NF is illustrated in Fig.5. Figure 5.
