Effect of adding residues of Trigonella foenum graecum L. to the soil on the growth and chemical content of wheat (Triticum aestivum L.)

M.S.Faysail, A.I.Ahmed

The present studywas conducted in the wired house for testing allelopathic ability of the Fenugreek plant residues taken from two stages of growth on some indicators of growth and chemical content of two cultivars of wheat. The analytic statistics of the resultsit explained that adding residues of shoot to the soil led to get stimulus in relative water content, decrease in the low injury index and led to increase in the concentration of Na, N, while addingroot residues led to increase in porline content and low injury indexwhile there was decrease inK concentrationas a result of addingshoot and root residues.The results showed that there was an increase in the concentration of N-Ca-Na-K in shoot system of the wheat compared with the concentration of these elements in root system.The early agestage (seedling stage) showed significant increase inthe concentration of N-Ca- Na-K and chlorophyll and proline and low injury index compared with mature stage.On other hand no significant differences were observed between cultivars (Al-Ize and Talafar-3) in chemical content but there was a superivity ofAl-Ize cultivar in some of its growth parameters.
