Abstract:
ABSTRACT
Two field experiments were carried out, at El-Gemmeza Agricultural Research Station during 2003/2004 and 2004/2005 seasons to study the effect of four phosphogypsum (PG) rates (0, 2.4 , 4.8 and
7.2 t PG /ha.) and five nitrogen levels ( 0, 47.6 , 95.2 , 143 and 190.5 Kg N /ha.) on yield and quality of flax variety Sakha 2. The results obtained showed that phosphogypsum application at the rate of 2.4 t PG/ha significantly increased fiber elongation and fiber fineness. Using 4.8 t PG /ha. produced the highest seed yield /plant. Increasing PG rate up to 7.2 t PG/ha. significantly increased technical stem length, fruiting zone length, straw, straw with capsules and fiber yield/ha., fiber length, number of capsules/plant, seed yield per plant as well as per hectare and oil percentage in both seasons. Application of N at the a of 95.2 kg N/ha. produced the highest fruiting zone length, fiber elongation, fineness and strength and oil percentage. Addition of N at a rate of 143 Kg N/ha. significantly increased straw yield per plant as well as straw, straw with capsules and seed yield per hectare. Increasing N level up to 190.5 Kg N/ha. significantly increased technical stem length fiber yield/ha.,
