Impact of Some Growth Regulators and Nitrogen Levels on Flax Yield and Its Quality
Abstract: ABSTRACT
The present investigation was carried out at Sakha Agric. Research Station Farm during the two successive seasons of 2002/2003 and 2003/2004 to study the effect of two nitrogen levels (35 and 70 kg N/fad) and some growth regulators i.e. GA3 at 20, 40 and 80 ppm and IAA and NAA at 10, 20 and 40 ppm of each one compared with the check treatment on yield and its components and quality of flax plants (Sakha 1 cv.). This study was laid out in a split plot design with four replications. The obtained results could be summarized as follows:
The application of 35 kg N/fad significantly increased stem diameter, fiber yield per plant as well as per fad., fineness and strength of fibers, seed oil content in both seasons and seed ash content in first season. Increasing nitrogen levels from 35 up to 70 kg N/fad. significantly increased seed index in second season, seed yield/fad. In first season, protein content and crude fiber in both seasons and total carbohydrate in first season.
The concentration of GA3 at 20 ppm gave the highest seed protein content. Application of GA3 at 40 ppm increased significantly straw and seed yields per fad., fineness and tenacity fibers. While, the high level of GA3 (80 ppm) increased significantly stem diameter, straw with capsule yield/fad., fiber yield per plant and per fad., fiber percentage and fiber length in both seasons. Spraying with IAA at 10 ppm increased significantly seed index, seed protein content. While, the same rate (10 ppm) from NAA gave the highest value for number of seed/plant in the first season. application with NAA at 40 ppm significantly increased fruiting zone length and straw with capsule yield/fad..
The interactions were significantly in most studied characters in both seasons.
