Abstract:

The experiment was conducted during the year 2017-18 at the instructional farm of Department of Plantation Crops and Processing, Faculty of Horticulture, Uttar Banga Krishi Vishwavidyalaya, West Bengal. The study was aimed to evaluate the effect of graded level application of boron and potassium and their interaction on under developed nuts, shed nuts and split nuts of terai region of West Bengal. The experiment was carried out in a 2.7×2.7 m spaced 12 year old planted with cv. Mohitnagar and laid out in factorial RBD having 12 treatments replicated 4 times with 4 different level of boron viz., B0, B1, B2 and B3 at 0g, 25g, 50g and sprayed with 4% Na2B4O7 solution along with 3 different level of potassium (K2O) viz., K1, K2 and K3 at 70 g, 140 g, 210 g of K2O per palm respectively to the bunches at 2nd, 4th and 6th months respectively per palm at nut development stage at regular intervals. Soil and nut samples are collected from 10 equidistant spots and 10 different palms respectively where as leaf sample is collected from the 4th index leaf (Ravi Bhat and Sujatha, 2014) from 10 equidistant palms for analysis before and after application of treatments. The results revealed that graded level application of boron and potassium shows that at higher level of boron(B2) shows increased potassium content in the soil and nut where as at (B1) the potassium content of the leaf showed highest and at (K3) the potassium content of the soil and nut showed highest potassium and at K2 level the potassium content of leaf is gradually increased (mg/kg) and their interaction effect shows that, higher level combination of both boron and potassium(B2K3) shows higher potassium content in the soil and nut (mg/kg) and also 0 level of boron and highest level of potassium showed increased potassium content in the leaf (B0K3) and also at B3K2 and B2K2 level of interaction the yield parameters like (fresh kernel weight and dry kernel weight) shows significant effect.
