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.
