Determination of Nutrient Cycling and Nutrient-use Efficiency in an Agroecosystem of Trifolium alexandrinum | Chapter 06 | Current Aspects in Pharmaceutical Research and Development Vol. 8

 

Trifolium alexandrinum L. is both a green pasture crop and an anti-diabetic medicinal plant in Egypt. The total forage phytomass was approximately 14.3 tonnes each fed year. The current study evaluates dry matter production, nutrient cycling, and nutrient usage efficiency (NTUE) in a T. alexandrinum agroecosystem using standard agricultural practises and farmer rotational clipping. The net above ground primary productivity was calculated to be around 0.066 and 0.093 g/g dry weight/day for the first and last three growth periods, respectively. The rate of nutrient accumulation in shoots was initially faster than the rate of biomass accumulation in shoots. There observed a concentration gradient of N and K from roots to shoots, indicating active translocation of these components to the shoot. The amount of N and K translocated exceeds 90% of the total N and K intake. The total organic constituents (TAC, CP, EE, and SOC) in the shoot attained their maximum content during the prolonged growth phase. Furthermore, variable levels of NTUE were discovered in T. alexandrinum throughout distinct growth stages. For the majority of elements, biomass allocation was the most important controlling factor in NTUE variations.
