This Study was conducted at the experiment Farm of Horticulture and landscape design Dep.- College of Agriculture and Forestry - Mosul University, during spring seasons of 2013 and 2014, to study and evaluate the response of two snap beans varities Strike and Brinco , to seed sowing rates 100 and 150 kg . ha .-1 and four types of organic and chemical fertilizers : Rotten sheep manure 60 m3 /ha., chicken manufactured poultry manure ltalpollina 100 kg / 1000 m2 , chemical fertilizer as recommended by the Iraqi Agriculture Ministry 60 kg Urea , 260 kg super phosphet . ha.-1 120 kg potassium sulphate . ha.-1 added after complete planting and 72 Urea . ha-1 after a month from the first addition) the previous chemical fertilizer added as zinc sulphate (ZnSo4) at 90.9 kg . ha.-1 by side dressing at sowing , in addition foliar application of chelated zinc sulphate at 50 mg.l-1 which added in two periods during flowering and bens sets in order to study their effects on the vegetative growth , quantity and quality in dry seeds . Evaluation of producted seeds in the 1st. season and their content of nitrate was done, which had been sownd in the 2nd. Varities and sowing rate exhibited significant effects in the percentages of the nitrogen, phosphors, potassium, protein and total carbohydrates of produced seeds. Seeds content produced from Strike var. was significantly superior in this trait over seeds content produced from Brinco var. and seeds content produced from to sowing rate 100 kg.ha.-1 was significantly better than seeds content produced from sowing rate 150 kg.ha.-1 in both season . Application of fertilizer by adding with zinc revealed a significant increase in the seed content of nitrogen, protein in both season, but showed a significant effect in the to percentage phosphors & carbohydrates in 1st. season. There is no significant effects in the percentage potassium in both season by adding fertilizer. Whereas, the triple intraction between studied factors (varities, sowing rates, adding fertilizer) showed non-significant effect in content of seed total zinc. The nitrate content did not significantly effect of the content pod produced from seed in the 1st. season and sownd in the 2nd. season.
