Bio-efficacy of Emamectin Benzoate 3.5% + lambda cyhalothrin 5% WP against sucking insect pests of chilli during <em>Rabi</em> season 2017-18 and 2018-19

Abstract

The field experiment was conducted to evaluate the “Effect of soil and foliar supplementation of nitrogen, boron and salicylic acid on growth and yield of cucumber (Cucumis sativus L.) in alfisols of Konkan (M.S.)” at Research and Education Farm, Department of Agricultural Botany, College of Agriculture, Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli, Dist. Ratnagiri (M.S.) during the Summer season of 2018. The experiment was laid out in Randomized Block Design (RBD) comprising ten treatment combinations replicated thrice, where the effect of soil and foliar supplementation of nitrogen, boron and salicylic acid either alone or in combinations applied along with the recommended dose of fertilizers (135:60:30 NPK kg ha-1) and an absolute control (to judge the fate of native nutrients) were studied. The study further revealed that the treatment receiving the application of recommended dose of fertilizer (135:60:30 kg ha-1) + Foliar spray of nitrogen through urea (1%) + Soil application of boron through borax @ 2 kg ha-1+ Foliar spray of salicylic acid (0.2%) was recorded the highest fruit yield (231.22 q ha-1) and yield attributing characters like number of fruits per vine (7.00) and weight of fruit i.e., 1.98 kg per vine as well as growth parameters viz.vine length (407.00 cm) and number of branches per vine (14.22) of Cucumber in alfisols of Konkan (M.S.).
