Abstract:
The present investigation was carried out to evaluate the interaction effect of potassium on extent of fruit colour in litchi during the year 2019. Ten years old uniformly grown “Deshi” litchi plants established at Fruit Research Station of Bihar Agricultural University Sabour, were Sprayed with K₂SO₄ and KCl @ 0%, 1% and 2% at two different stages i.e. Marble and Stone hardening. The plants treated with potassium as foliar feeding significantly improved fruit skin colour and quality attributes over the control. Anthocyanin content higher with K₂SO₄ application at stone hardening stage. So, it is concluded that K₂SO₄ @1% and 2% at stone hardening stage significantly improved anthocyanin content litchi cv. Deshi. Fruit quality characteristics viz. total sugars, reducing sugar were also enhanced with marble and stone hardening stage with sprays of different concentrations of potassium fertilizers over untreated trees. So, it is concluded that K₂SO₄ @1% and 2% at stone hardening stage significantly improved total sugar, reducing sugar and anthocyanin litchi cv. Deshi.
