Evaluation of integrated nutrient management on the performance of bottle gourd [Lagenaria siceraria (Molina) Standl.

Abstract

The present investigation was conducted during 2011-2012 and 2012-2013 at Horticulture Research Station, Mondouri, Bidhan Chandra Krishi Vishwavidyalaya, Monhanpur, Nadia, West Bengal, India, to find out the effect of organic manure, chemical fertilizers and bio fertilizers in an integrated manner for yield maximization and quality improvement in bottle gourd cv. Pusa Naveen. The experiment consisted of eleven nutrient based treatment combinations, including different level of applications of inorganic fertilizers (Urea, single super phosphate and muriate of potash), organic manure (vermicompost) and bio fertilizers (Azotobacter and PSB). Present investigation clearly indicated the beneficial effect of integrated nutrient management on yield and quality characters of bottle gourd. The maximum length of main vine (226.00 cm), branches per plant (5.67), fruit number (10.00), fruit weight (873.33 g), fruit length (21.07 cm) and fruit diameter (8.18 cm) were recorded in the treatment which received equal proportions of N from inorganic and organic sources along with bio fertilizers (Azotobacter and PSB). Quality characters namely, total soluble solids (TSS) and ascorbic acid in bottle gourd fruit were enhanced in the most favourable way due to application of 75% N from inorganic source and 25% N from organic source along with bio fertilizer (PSB). Keeping view on yield sustainability, balance in ecosystem, soil health improvement and good health of human beings, it may be suggested that vegetable growers particularly in new alluvial zone of West Bengal may supplement 25-50% recommended dose of nitrogen through vermicompost in bottle gourd cultivation along with bio fertilizers viz. Azotobacter and PSB.
