The Effects of Biofertilizers, Organic and Inorganic Nutrient Sources on Growth Parameters and Yield of Piper betle L. (Betlevine) under Gangetic Alluvial Soil of West Bengal

An experiment was carried out during two consecutive years of 2012-13 and 2013-14 at the experimental site of AICRP on MAP and Betelvine, Bidhan Chandra Krishi Viswavidyalaya, Kalyani, Nadia, West Bengal. The experiment was laid out in a randomized block design (RBD) replicated thrice with 9 treatments comprising of different combinations of organics (Azotobacter, Phosphobacter and mustard oil cake) and inorganic (urea and SSP) sources of nutrients. The maximum vine elongation, basal girth, leaf size, leaf yield and other yield attributing characters were found significantly better under application of Azotobacter @ 10 Kg + 140 kg N (MOC) + Phosphobacter @ 5 Kg + 50 Kg P +100 Kg K ha-1year-1. However, the treatment was statistically at par with Azotobacter @ 5 Kg + 170 Kg N (MOC) + Phosphobacter @ 5 Kg + 50 Kg P + 100 Kg K ha-1year-1 in respect of dry matter production. Hence, the treatment with Azotobacter @ 10 kg + 140 kg N (MOC) + Phosphobacter @ 5 Kg + 50 Kg P +100 Kg K ha-1year-1 application can be used as a best sustainable and eco friendly integrated nutrient management approach for better yield of betelvine under the gangetic alluvial zone of West Bengal.
