Effect of zinc sulphate, ferrous sulphate and borax on yield and quality of aonla (Emblica officinalis Gaertn.) cv. NA-7
Keywords:
Aonla, zinc sulphate, borax, foliar spray micronutrientAbstract
The investigation was taken up at MES Horticulture, NDUAT, Ayodhya to improving the fruit yield and enhancing the
fruit quality through foliar application of micronutrients in aonla cultivar NA-7. The study revealed that the foliar spray of
micronutrient combination of% ZnSO40.5 % + FeSO4 0.5%+ Borax0.25 %) significantly increased yield (6.93 tonnes/ha). The
yield was almost double as compared to control in the said combination of micronutrients as a result higher benefit cost ratio (3 .60)
was recorded. Further, the quality parameters of fruits such as higher total sugar, reducing sugar and non-reducing sugar content of
fruits was significantly improved without reducing the vitamin C ( 483. 71 mg/100 g) with the above said combination of nutrients.
Hence, the micronutrient combination ofZnSO4 0.5 % + FeSO4 0.5 % + Borax 0.2 5% holds immense potential as a foliar spray in
arresting fruit drop and doubling up the yield in aonla.
