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 boron content in soil, leaf and nut (mg/kg) and their interaction effect on yield parameter in the boron deficient soils 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 whereas 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) and potassium (K3) the boron content is gradually increased in the soil, leaf and nut (mg/kg) and their interaction effect shows that, higher level combination of both boron and potassium (B2K3) shows higher boron content in the soil, leaf and nut (mg/kg) and at B3K2 and B2K2 level of interaction the yield parameters shows significant effect.
