Effects of Different Irrigation Levels on Selected Crop Parameters of Sesame (Sesamum indicum L.) Under Semi-Arid Highland Conditions in Turkey

Abstract

A trial was carried out in the fields of Siirt University (Turkey) to determine the effects of different irrigation levels on selected crop parameters of three sesame genotypes. Applications of different water consumption levels (WCL) (35%, 70% and 100% water levels; S1, S2 and S3 respectively) were in the main plots and varieties were in sub-plots. Trials were established in three replications according to the divided parcels experimental design in the random blocks. Two sesame cultivars (Arslanbey and Hatipoğlu) and one sesame genotype (Hat-2) were used. Plant height were higher for Hatipoğlu and Arslanbey varieties (111,1 cm and 107,4 cm, respectively). In relation with water consumption levels, plant heights were higher at S3 treatment for both years and S2 treatment for 2017. First branch height were higher for Arslanbey variety and Hat-2 genotype (7,37 cm and 6,36 cm, respectively). In relation with water consumption levels, plant heights were higher at S3 treatment for both years and S2 treatment for 2016. Branch number were higher for Hatipoglu variety (8,52 pieces) and lower for Arslanbey variety (3,48 pieces) and Hat-2 genotype (3,74 pieces). In relation with water consumption levels, branch number were higher at S1 and S2 treatments for both years. Hatipoglu variety in 2017 year produced highest (9,47 pieces), whereas Arslanbey variety in 2016 produced lowest (2,79 pieces) branch number. Number of capsules per plant values were higher for Hat-2 genotype (160,8 pieces) and Arslanbey varieties (151,3 pieces). Number of capsules per plant was 135,5 pieces for Hatipoğlu variety. Number of seeds per capsules values were higher for Hat-2 genotype (85,42 pieces) and lowest for Hatipoğlu variety (79,26 pieces). None of the application was effective on 1000 seed weight values.
