Abstract

The effect of spacing and nutrient management on physiological and biochemical properties of orangefleshed  sweet potato var. Gouri was studied under foot hill conditions of Manipur. The physiological  parameters such as relative water content (RWC) and chlorophyll stability index (CSI); biochemicalparameters such as protein content, total soluble sugar (TSS) and reducing sugar (RS) and NPK  contents in leaves and tubers showed significant variation due to spacings (S1: 60 x 20 cm and S2: 60  x 30 cm) and NPK rates (F1: 60:40:60 ; F2: 75:50:75; F3: 90:60:90 kg ha-1). The RWC and CSIincreased with increasing nutrient doses under spacing S1 and decreased at spacing S2. The NPK  content, TSS and RS in leaf tissues increased significantly with increasing doses of NPK. The leaf  protein content increased with increasing rates of NPK at wider spacing (S2). The treatment  combinations, S1F2 (33.0 t ha-1) and S2F3 (32.7 t ha-1) produced significantly higher tuber yield. Thestudy revealed that NPK @ 75:50:75 kg ha-1 and spacing of 60 x 20 cm can be recommended for  higher productivity and tuber quality of sweet potato under foot hill conditions of Manipur.
