Abstract

• The effect of days interval water treatment on growth of Sacha inchi (Plukenetia volubilis L.) was studied in this experiment. The field experiment was conducted in the field of Department of Agricultural Research Oil Crops, Research center in Magway Region (May2019-2020). This experiment with four replications in a completely randomized block design, T1 3days interval T2, 6days interval, T3 9days interval and T4 daily water treatments. The collected data such as plant height, number of branch, number of node, number of leaves, leaf area. The result of different days interval water treatment showed that the tallest plant height (90.97 cm), the maximum-number of branch (1.86), the maximum number of node (21.94), the maximum number of leaf (15.86), the largest number of leaf area (590.95 cm2 ) were obtained from daily water treatment in this study.
