Effect of foliar feeding of calcium and micro-nutrients on quality parameters of strawberry (Fragaria x ananassa Duch.) cv. Nabila under net tunnel

Abstract

The experiment was conducted at Research Farm of Centre of Excellence on Protected Cultivation and Precision Farming under net tunnel, College of Agriculture, IGKV, Raipur (C.G.) to find out the beneficial effect of Ca and micro-nutrients on quality attributing parameters of strawberry cv. Nabila under net tunnel condition with ten treatments and three replications in Completely Randomized Block Design. The treatment consisted ten different concentrations of Ca and micro-nutrients along with recommended dose of fertilizers viz. T0: RDF + Control (water spray), T1: RDF + CaCl2 @ 0.4%, T2: RDF + CaCl2 @ 0.6%, T3: RDF + CaCl2 @ 0.8%, T4: RDF + ZnSO4 @ 0.4%, T5: RDF + ZnSO4 @ 0.6%, T6: RDF + ZnSO4 @ 0.8%, T7: RDF + FeSO4 @ 0.4%, T8: RDF + FeSO4 @ 0.6% and T9: RDF + FeSO4 @ 0.8%. As regards the quality parameters i.e. total soluble solids, TSS: acid ratio, total sugar, reducing sugar, non-reducing sugar and ascorbic acid content were recorded maximum under the treatment RDF + ZnSO4 @ 0.6%, however the minimum acidity (0.42%) was recorded under the same treatment.
