Effect of seeding rate and npk compound fertilizer on growth and yield of flax (Linum usitatissimum L.)‎

Abstract EN

This study was conducted during the winter agricultural season 2019/2020 in two locations, the first in Tel Kaif district, which is 20 km north from the center of Mosul, and the second in Al-Hamdaniya district, 25 km southeast of Mosul, to study the effect of three seeding average(30, 40 and 50 kg.

ha-1) and four levels of compound fertilizer N15P15K15 (zero, 100, 150 and 200 kg.

ha-1) in growth, yield and quality of flax under dehydrating conditions, the experiment was conducted in the field according to a randomized complete block design (RCBD) with three replications.

The results indicated that the seeding average of 30 kg.

ha-1 was significantly excelled in the traits: number of fruiting branches.

Plant-1 and number of capsules.

plant-1, percentage of oil in seeds for both locations, and number of seeds.

Capsule-1 and the weight of 1000 seeds at the Tel Kaif location, and the seeding average of 50 kg.

h-1 was significantly excelled on the seed yield and the percentage of linolenic acid in both sites, and the plant height at the Tel Kaif location.

The level of the compound fertilizer 200 kg.

ha-1 was significantly higher in the trait: plant height and number of fruiting branches.

Plant-1 and the number of capsules.

Plant-1 and the number of seeds.

Capsule-1 at Al-Hamdaniya location, while the percentage of linolenic acid was superior at Telkaif location, and the percentage of oil in the seeds and oil yield reached the highest amount at the same level of the compound fertilizer in both locations.

The interaction of seed average with the levels of the compound fertilizer indicated a significant and varied superiority in the trait: plant height and number of fruiting branches.

Plant-1 and the number of seeds.

Capsule-1 and weight 1000 seeds for both locations.
