Morphological Characterization and Chemical Composition of a Variety of Medicago (Triad): A Study in Flowering Stage and In-vivo Digestibility of its Hay | Chapter 5 | Advanced Research in Biological Science Vol. 5

 The aim of this study search out precisely forecast biometrical traits at the phenological bud stage of the Medicago introduced (Triad) (deliberate an ideal stage that delivers preeminent supporter nitrogen value), to appreciate its synthetic makeup, and in the end to assess the digestibility of allure hay in nearby someone following orders without question. Biotic and abiotic stresses are severely confining plant production and output. Of notable importance is seasoning stress that not only limits plant growth and survival, but influences the soil fertility and warns agricultural environments sustainability. The problem is infuriate in fragile dry and semi-dry areas place high dissolution, low rainfall and the use of salty water for watering is accelerating soil salinization. Imported tenable Medicago has a high digestive content and is utilized as two together hay and green feed for ruminants. The synthetic makeup of medicago in the developing stage results in a mild ruins content, ranging from 6,547 to 7,011% DM. The range of TNM content at this stage's trio is 15,34% MS to 20,75% DM. As for NDF's fiber content, it is 44%. With the exception of DM and MM, the three divisions' parameter difference analyses tell a difference that is to say very significant (P < 0,0001). The Principal Components Analysis (PCA) shows that width of stems is opposing to planet seen at dawn and lignin quantity. The two last limits have contributed to locate the first division in this cut. Germination density (number of plant /m²), yield in dry and in green and average climax of stems locate the second portion in the same stem. The DWC of OM and of hay medicago TNM at developing stage is relatively feeble for nitrogen, respectively of 69% and 55.5% Different tests on the unchanging fodder in accordance with years and domains of harvest is necessary in consideration of have weaker and more correct averages values.
