Influences of integrated use of organic and inorganic sources of nutrients on growth, flowering and yield of garden pea (Pisum sativum L.) cv. Bonneville

Abstract

An experiment was conducted to examine the response of four different organic manures viz. farmyard manure, vermicompost, castor cake and poultry manure as a source of nitrogen with or without chemical fertilizers, phosphorus and potassium and biofertilizer i.e. PSB in a randomized block design with three replications during the rabi season of the year 2012 and 2013. The results revealed that, the significantly highest vine length at 60 (86, 84 and 85 cm) and 90 DAS (117, 120 and 119 cm) was recorded with T15 (Recommended dose of N as Vermicompost + P and K + PSB) during the year 2012, 2013 and in pooled analysis, respectively. The significantly early flowering (58.6, 59.3 and 59.0 days), maximum number of pods per plant (7.4, 7.7 and 7.5) and highest weight of pod (7.3, 7.0 and 7.1 g), maximum yield of pods per plot (5.3, 5.1 and 5.2 kg) and yield of pods per hectare (137.9 q, 134.9 q and 136.4 q) was recorded with T18 (Recommended dose of N as Poultry Manure + P and K + PSB) during the year 2012, 2013 and in pooled analysis, respectively.
