تقيين استخدام الأسمدة العضوية السائلة في تسميد محصول الرز

Abstract EN

Afield experiment has been conducted in the Mishkhab Rice Research station in Najaf Governorate during two consecutive rice seasons in 2010 and 2011 to evaluate the use of four types of liquid vegetal organic fertilizer , namely : Tecno Kel , Agri M40 , Tecamin Algae and Tecamin Max on the quality and productivity of the yield .

Two rice varieties , namely : Anber-33 and Jasmin have been utilized to evaluate the effect of the organic fertilizers on the yield and growth characteristics .The treatment is compared with the chemical fertilizer recommended by the National program for Rice Development .

The experiment is designed using the Random Complete Block Design (RCBD) technique .

The results reveal significant superiority of (Agri-M40) achieving grain yield of (5811) and (5571) kg/ha for the 2010 and 2011 experiment respectively .

These results are attributed to the improved qualities of this organic fertilizer such as the reduced rate of infertility , as well as the enhanced weight of the grains based on the scale of 1000 grains method , compared with the traditional chemical fertilizers commonly used in rice plantations in Iraq .

Therefore , the use of extraction of vegetal manure for fertilizing the rice fields instead of chemical fertilizers is recommended to reduce the polluting impact on the environment .
