Abstract:

The experiment was conducted for two consecutive years during 2014-15 and 2015-16 at the Instructional Farm of Uttar Banga Krishi Viswavidyalaya, West Bengal located at 43 m above mean sea level with 26°19/86//N latitude and 89°23/53// E longitude. The study was aimed to evaluate the effect of potassium-boron interaction on leaf nutrient content and nut setting of coconut in the boron deficient soils of terai zone of West Bengal. The experiment was carried out in a 7.5 m x 7.5 m. spaced 11 years old plantation planted with cv. ECT and laid out in Factorial randomized block design having 9 treatments replicated four times with 3 different levels of Potassium (900, 1200 and 1500 g of K2O per palm) and Boron (25, 50, and 100 g borax/palm). Soil samples were collected from 0 to 30 cm depth within a radius of 1.5 m of the trunk of each palm of the entire experimental area of the plantation and the leaf samples from 14th frond was taken for analysing boron and potassium at 6th and 12th months after soil application of potassium and boron. The results revealed that the leaf potassium content showed an increasing trend for the intermediate levels of boron. However, higher leaf boron content recorded with higher rate of boron application. The treatment receiving intermediate dose of potassium and boron registered higher number of female flowers and fruit setting.
