THE EFFECT OF PLANT DENSITY ON POD YIELD AND SOME AGRONOMIC CHARACTERISTICS OF DIFFERENT GROWTHTYPE PEANUT VARIETIES (Arachis hypogaea L.) GROWN AS A MAIN CROP*

Abstract

This study was conducted at the University of Cukurova, Faculty of Agriculture research area in 2018 and 2019 in Adana, Turkey. The objective of this study was to determine the effect of plant density on pod yield and some agronomic characteristics of different growth type peanut varieties (Halisbey and NC-7) in main crop growing condition. In this research; five different intra-row spacing (5, 10, 15. 20 and 25 cm) were used in single row planting pattern. The experimental design was a split plot with three replications. Pod number and pod weight per plant, 100 seed weight, shelling percentage, oil and protein content, pod and kernel yield per hectare characteristics of varieties were investigated. As a result; pod number and weight per plant and 100 seed weight values were decreased when the plant density was increased, but shelling percentage, pod and kernel yield and protein percentage values were increased. The oil content was not affected by the plant density. The highest pod yield (6652 kg ha-1 ) was obtained when the seeds planted at 5 cm inter-row spacing (28.5 plants m-2 plant density). The highest pod yield was obtained from Halisbey variety.
