Assessment of avoidable yield losses due to root-knot nematode, Meloidogyne incognita infesting Indian spinach (Basella alba L.) under West Bengal field conditions

Abstract

The field experiment was conducted during April, 2016 & 2017 at Central research Farm (CRF) of Bidhan Chandra Krishi Viswavidyalaya, West Bengal to assess the avoidable yield losses due to root- knot nematode in Indian Spinach cv. Local (Basella alba L.) under field conditions with paired plot design with ten replications by soil application of Carbofuran granules @ 3 kg a.i./ha. Ten plots each of 6 m x 2 m size were treated and another ten plots were kept untreated control (without Carbofuran application).The results indicated that the loss in yield of Indian Spinach in an untreated ranged from 10.82 % to 12.44 %. However, average avoidable loss in the vegetative yield of the crops was recorded to be 9.76 % to 11.06 per cent, when the crop was treated with Carbofuran granules @ 3 kg a.i./ha.
