Studies on Effect of Harvest Height, Harvest Interval and Foliar Nutrients on Leaf Yield and Quality of Curry Leaf (Murraya koenigii Spreng.)

A field experiment on effect of harvest techniques and application of foliar nutrients on yield and quality of curry leaf (Murraya koenigii Spreng.) was conducted at Department of Spices and Plantation Crops, Horticultural College and Research Institute, Tamil Nadu Agricultural University, Periyakulam during 2015. The experiment was laid out in split-split design consisting of three factors, viz., factor-I harvest levels (L₁-15 cm and L₂-30 cm), factor-II harvest intervals (H₁-2 months harvest interval and H₂-3 months harvest interval) and factor-III foliar applications of biostimulants (N₁-0.25 per cent ZnSO₄, N₂-0.25 per cent FeSO₄, N₃-2 per cent seaweed extract and N₄-0.3 per cent humic acid) constituting sixteen treatment combinations. Data on quantitative and qualitative traits were recorded from randomly selected five plants and the data were subjected to statistical analysis. The results have shown that among the harvest techniques and foliar nutrients the highest leaf yield (643.50 g per plant) ascorbic acid (2.58 mg per 100 g), calcium (840.18 mg per 100 g), magnesium (769.69 mg per 100 g) and iron content (2.74 mg per 100 g), were recorded by the treatment combination L₂H₂N₄ (30 cm harvest height + three months harvest interval + 0.3 per cent of humic acid)
