Title

THE OF STUDY THE RESPONSE CURVES CHANGES AND THE RELATIONSHIP AMONG MORPHOLOGICAL TRAITS OF AGROPYRON. CRISTATUM UNDER DIFFERENT AMOUNTS OF HUMIC ACID FERTILIZER

Pages

  29-44

Abstract

 The effect of HUMIC ACID on vegetative growth of pasture AGROPYRON CRISTATUM was evaluated in 2010 as a pilot in the greenhouse in Damavand, Iran. HUMIC ACID granular fertilizer to the value of 0, 75, 150 and 225 kg per hectare was used. Correlation analysis results showed that under conditions of Cody there was a significant positive correlation among most traits. Stepwise regression analysis showed that the effect on shoot fresh weight of tillers, leaves and stem fresh weight, root length, shoot dry weight ratio of air to the roots, chlorophyll b and carotenoids, leaf, root dry weight and leaves. The increase in leaf area, chlorophyll a, chlorophyll b, chlorophyll and total carotenoids increased the degree of amount of fertilizer, the amount of each fertilizer HUMIC ACIDs in length, plant height, fresh weight and dry weight of roots and dry leaves of the degree of The third will follow the path analysis results indicated that the most effective traits including fresh weight, shoot fresh weight of leaf, stem fresh weight, root length, leaf dry weight, shoot dry weight ratio of air to the roots, chlorophyll b, carotenoids, and leaf were. The most appropriate amount of HUMIC ACID is 225 kg per hectare.
