Effect of sowing date and n-fertilizer levels on seed yield, some yield components and oil content in flax
2009
Ibrahim, H.M.
Two field experiments were carried out at the Agricultural Research Station, Alexandria University, Abbis, in 2003/2004 and 2004/2005 winter seasons to study the influence of four sowing dates (November 1 and 15 and December 1 and 15) and three nitrogen levels (107, 143 and 179 kg / ha) on seed yield, some yield components and seed oil content of Giza 8 flax cultivar. Delaying sowing date beyond November 15 significantly decreased seed yield and all studied seed yield components, in addition to seed oil content. The late sowing might shorten the growing cycle of plants, which, finally, resulted in a fewer number of capsules/plant and shorter seed filling period. Increasing the level of applied N fertilizer from 107 up to 179 kg/ ha increased seed yield and all its components , in addition to seed oil content, while, plant height decreased with increasing N fertilization level above 143 kg/ ha. The linear response of f ax yield and other studied characters to nitrogen treatments indicated that the higher rates above 179 kg/ ha were suggested to be investigated.
