Effect of Mineral and Bio-Phosphorus Fertilization and Zinc Levels on Flax Yield and Quality
Abstract: ABSTRACT

Two field experiments were carried out at El-Gemmeza, El-Gharbia Governorate, Egypt, Agricultural Research Station, Agricultural Research Center, during 2003/2004 and 2004/2005 winter seasons to study the effect of six levels of mineral phosphorus and bio-phosphorus (phosphorien); i.e. zero, 36 kg P2O5/ha., 72 kg P2O5/ha.,
36 kg P2O5/ha. + phosphorien , 72 kg P2O5/ha. + phosphorien and phosphorien with three levels of zinc; i.e., zero, 24 and 48 kg zinc sulphate/ha. on flax Sakha 1 cultivar. This study was laid out in a split -plot design, with four replications, the main plots were allocated to the P levels, whereas, the sub- plots contained the Zn levels. The obtained results could be summarized as follows:

Adding 36 kg P2O5/ha. significantly increased fruiting zone length (in both seasons) and the number of seeds / capsule in the second season. Increasing phosphorus levels from zero up to 72 kg P2O5/ha. significantly increased straw yield/plant. Application of 36 kg P2O5/ha. with phosphorien significantly increased stem diameter and straw , straw with capsules, fiber and seed yields/ha., number of capsules / plant, number of seeds/plant and seed yield/plant. Addition of 72 kg P2O5/ha. with phosphorien significantly increased oil percentage. Seed inoculation with phosphorien significantly increased fiber length, fiber fineness, fiber strength and seed index in both seasons.

Increasing zinc from zero up to 24 kg zinc sulphate /ha. significantly increased technical stem length in the second season, fruiting zone length, stem diameter, straw yields per plant and per hectare, fiber length, number of capsules /plant, number of seeds/capsule, number of seeds/plant and seed yields per plant and per hectare. Increasing zinc level from zero up to 48 Kg /ha. significantly increased fiber fineness and strength and oil percentage in both seasons. The interactions among the studied factors had significant effects on straw and seed yields in most characters in both seasons.
