Abstract

The field experiment was conducted to assess 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) on quality and nutrient content of cucumber (Cucumis sativus L.) in acid Alfisols of Konkan 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 in Randomized Block Design (RBD) comprising ten treatment combinations replicated thrice. The results revealed that the quality parameters of cucumber grown in acid Alfisols of Konkan viz., TSS, reducing sugar, total sugar and titratable acidity; nitrogen, phosphorus, potassium and boron content in plants significantly increased and recorded the maximum values due to 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%) along with 15 t ha-1 FYM.
