Abstract

In order to study effect of deficit irrigation and cultivar on yield and yield components of soybean, a field experiment was conducted at the Ordukhan Agricultural Research Center, Heart Province-Afghanistan (Geographical longitude: 62° 11'29" east and geographical latitude: 34° 20'35" north) during the cropping season 2017-2018. The experiment was conducted in a split-plot arrangement based on randomized complete block design with three replications. Deficit irrigation with three levels (70 (no stress), 90 (Moderate stress) and 110 (severe stress) mm evaporation from class A evaporation pan) were considered as main plots and cultivars with four levels (Glway, Stine, Hong and LD04) were allocated as sub plots. Analysis of variance showed that the deficit irrigation had significant effect on number of pods per plant, number of grains per pod, 100 grains weight, Biological yield, Grain yield and harvest index the effect of cultivar on all traits and the effect of interaction between two factors on 100 grains weight were significant. The results showed that the deficit irrigation at 110 mm evaporation (severe stress) cased of significantly reduced of all traits. The lowest number of pods per plant (109. 8 pods), number of grains per pod (2. 4 grains), 100 grains weight (15. 27g), Biological yield (7363 kg/ha), Grain yield (2899 kg/ha) and harvest index (35. 5%) were obtained in 110 mm evaporation. The means of traits at 70 mm (no stress) and 90 mm (Moderate stress) evaporation had no significant difference. The LD04 cultivar had the highest Grain yield (3793 kg/ha), because this cultivar had optimum yield components. Simple correlation coefficient of traits showed that the Grain yield had positivesignificant correlation with Biological yield, number of pods per plant, plant height, and number of grains per pod. Based on, these results deficit irrigation up to 90 mm evaporation can be considered.
