| Abstract | ||||
| The hand sowing in Egypt is still the most popular in sowing flax crop. The increment of yield from seeds, fiber and straw of flax considered the greatest challenge of Egyptian planting. To obtain a good yield and quality for flax crop must have a good system to regulate seed distribution during the sowing process. Therefore, the aim of this study is to modify the Stegsted planter, model H119A by replacing its furrow opener (hoe type) with finger shape (four fingers each one) to improve distribution of flax plants in the field by decreasing density of plants in longitudinal centimeter (1.15 cm instead of 2.30 cm before modification) and narrowing distance between rows (5cm) instead of 10 cm to excess productivity of variety of flax crop (Sakha1) for seeds, straw and fiber yield. The rate used of seeds 80 kg/fed. Two field experiments were carried out during 2005/2006 and 2006/2007 successive seasons at Gemmiza Agriculture Research Station, El-Gharbia Governorate to study the effect of four tractor forward speed (0.46, 0.71, 0.95 and 1.19 m/s) were used, modified finger shape at height of (0.00, 0.01 and 0.02 m) above soil surface and tilt angle on vertical direction of finger shape of (15.5, 18.5 and 21.5 degrees) on yield components, technological characteristics of Sakha 1 flax variety. The results of the present investigation indicated that: 1- The lowest values of (C.V.%) of the plant distribution obtained by modified machine (7.61% and 5.46%) at longitudinal and transverse directions resp. at forward speed 0.46 m/s, tilt angle of finger 15.5 degree and height of finger 0.00 m. 2- The highest yield of seeds, straw and fibers were (0.697, 3.967 and 0.727 ton/fed.) for Sakha1 by using modified machine at forward speed 0.46 m/s, tilt angle of finger 15.5 degree and height of finger 0.00 m. 3- The lowest values of the main stem diameter were (1.33 mm), at forward speed 0.46 m/s, tilt angle of finger 18.5 degree and height of finger 0.00 m, technical length (71 cm) and total length (84 cm) at forward speed 0.46 m/s, tilt angle of finger 15.5 degree and height of finger 0.00 m. The consumed energy 37.87kW.h/fed.at concluded tested factors while before modification and hand sowing were (43.29 and 0.29 kW.h/fed), resp < /p> | ||||
