Study of vertical mulching on physico chemical characters of tender nut water in coconut (Cocos nucifera L.) cv. Cod

Abstract

A study was conducted to find out the physico-chemical characters of tender nut water in coconut (Cocos nucifera L.) cv. COD. In the present study, the tender nut water samples were collected from 7 months old tender nuts and were subjected to quality analysis viz., pH, acidity, TSS, Total sugars, Vitamin C and minerals like calcium (Ca), potassium (K), magnesium (Mg), sodium (Na), iron (Fe), phosphorus (P), zinc (Zn). Among the different treatment combinations, pH (5.45), acidity (0.093%), TSS (6.19 oBrix), Vitamin – C (2.42 mg/100 ml), total sugars (5.62%) and minerals like calcium (42 mg%), potassium (296 mg%), magnesium (17.26 mg%), sodium (39.3 mg%), iron (4.23 mg%), phosphorus (8.53 mg%), zinc (0.85 mg%) was high in the treatment combination, D1N6 (D1 - vertical mulching at 30 cm depth; N6 - Vermicompost 20 kg + Urea 1.23 kg + SSP 2kg + MOP 2 kg + Coconut micronutrient mixture 1 kg + Biofertilizers (Azospirillum & Phosphobacteria) 50 g each + VAM 200 g).
