Evaluation of the Growth, Yield, and Nutritional Composition of Five Newly Tomato (Lycopersicum esculentum Mill.) Varieties Under Agro-Climatic Condition at Sulaymaniyah Governorate-Iraq

Abstract

This study was carried out to evaluate the comparative performance of five tomato cultivars in the Krbchna Village/Sangaw areas of Sulaimani province-Kurdistan region, Iraq during 2021. To study yield quantity and quality parameter in tomato fruits. The cultivars were Bistansoor, Sulaimani, Braw, Bakrajo and Amad. The experimental design was complete randomized block design (CRBD) with three replicates. The Fruit weight (g), size (cm3), length (mm), diameter (mm), shape index, firmness (g), pH, TSS%, TA%, TSS/TA, M%, D.M%, juice%, pectin%, lycopene (μg/ml FJ), sugars%, and potassium%. The Bistansoor variety obtained the maximum values of fruit weight (g), size (cm3), length (mm), diameter (mm), shape index, firmness (g) and lycopene% with (147.18g, 133.33cm3, 93.05mm, 47.16mm, 1.97, 660.50g and 79.69 μg/ml FJ) respectively. Sulaimani variety achieved a higher value of TSS/TA only with (14.26). Braw variety gave a maximum value of pH and M% with (4.23 and 94.00%) respectively. Bakrajo variety gave the maximum values of pectine and K% with (4.22% and 4.64%) respectively. While Amad variety achieved the maximum values of TSS%, TA%, D.M%, juice% and sugars% with (9.20%, 0.78%, 10.34%, 72.42%, and 4.59%) respectively.
