Row Spacing and Seeding Rate Effect on Growth Parameters of Flax (Linum usitatissimum L.).

Abstract

Many factors effect on growth parameters of crops. During this current study row spacing and seeding rate were selected as main factors to improve growth parameters of flax (Thorshansity 72, “Poland cultivar”). The study was carried out in Gardarasha Field, Faculty of Agricultural Engineering Sciences, Salahaddin University – Erbil. It was done on 15th November 2018. Results indicated that both factors and interaction between them significantly affected some studied characteristics. The highest plant height was recorded in the situation of (C1S1) row spacing and seeding rate (8cm and 3g/m2), respectively it was by (73.7cm). Additionally, row spacing significantly affected of technical stem length and fruit zone length. Once more, the best value for both parameters were recorded when row spacing 8cm so the values were (56.5 and 17.5cm), respectively. Interaction between the factors were highly significant affected a number of capsules/plant so the best value was recorded with the situation of (C1S1) by (17.0) capsules/plant. According to the results can conclude that row spacing and seeding rate are more important to improve growth parameters and then fiber yield of flax.
