Two field experiments were carried out at Sheikh Mohamed location which is far about 30 km west north Mosul city conducted during 2007-2008 and 2008-2009 winter seasons to study three genotypes performance of flax crop (Linum usitatissimum L.), three planting dates, and their interactions on some growth characters, yield and its components traits as well as oil yield.
The main findings could be summarized as follows:
The results showed that planting dates significantly affected in growth characters, yield and its component as well as oil yield in both seasons. The sowing of flax crop on the first November gave the highest number of capsules per plant, number of seeds per capsule, weight of thousand seed, seed, oil yield per hector. Sowing on the first November surpassed these sown on mid November in seed yield per hectare-1 by 20.32% and 20.67% as well as sown on mid October by 17.80% and 12.55% in the first and second seasons respectively.
Flax crop genotypes significantly differed for all studied yield and its component in both seasons. The highest number of capsules per plant, weight of thousand seed, seed and oil yield per hectare-1 were produced from Strain genotype in both seasons. The results indicated that Strain genotype exceeded Belinka genotype by 12.88% and 15.59% and Hera genotype by 15.26% and 18.86% in total seed yield per hectare-1 in the first and second seasons, respectively.
The interaction between planting dates and genotypes significantly affected in plant height, stem diameter, number of fruiting branches, number of capsules per plant, number of seeds per capsule, weight of thousand seed, total seed yield per hector, oil percentage and oil yield in both seasons, except for number of capsules per plant, number of seeds per capsule, weight of thousand seed and oil percentage in the second season only. The sowing of Strain genotype in the first of November gave the highest number of capsules per plant and total seed yield per hectare-1 in both seasons.

The study included two field experiments for (Helianthus annuus L.) conducted during spring growing seasons of 2009, 2010 in two locations. The first Sheikh Mohamed 25km west north Mosul city, the second ones Gueer 50 Km east of Mosul city at Nineveh province .The main objective was to find out effect of zinc foliar application on the growth, yield and quality of some Sunflower genotypes. Each experiment was conducted according to factorial experiment in a randomized completely block design with three replications. Each experiment included three levels of zinc foliar application (0, 5 and 10 mg.L-1) were sprayed on the leaves one dose during 6 leaves stage, with three genotypes of Sunflower crops (Record, Mlabar and Fodak). The genotype Mlabar gave a high level for characters Plant height (161,152 cm), stem diameter(2.06,2.20cm), leaf area index(1.78,1.74), dry weight of the head, head diameter flower disc (21.90 , 22.20 cm), number of seeds/head, weight of thousand seed, total seed yield (2.49, 2.49 ton.hectar-1), oil percentage (43.33 , 44.01 %) and oil yield (1.07, 1.09 ton/ha.) in both locations Sheikh Mohamed and Gueer respectively. The foliar application the zinc to the leaves with concentration 10 mg.L-1 lead to a significant increase in plant high (173.55, 163.63cm), while increasing concentration of zinc to 5 mg.L-1 cause a significant increase in number of leaves/plant, leaf area index, dry weight for flower disc, disc diameter (22.32, 22.87 cm) , number of seeds/head, weight of thousand seed, seed yield (2.73, 2.72 ton.hectar-1) and oil (%), oil yield (1.22,1.24 ton.hectar-1) in Sheikh Mohamed and Gueer locations respectively. The interaction between the genotypes and foliar application was significant in some of growth, yield and quality characters, the Mlabar genotype with zinc application to the leaves with concentration 5 mg.L-1 was superior for head diameter (22.92 , 23.27 cm), thousand seed weight (82.63 , 81.53 g), oil yield (1.33, 1.30 ton.hectar-1) for the Sheikh Mohamed and Gueer locations respectively
