Abstract

A comprehensive in- vitro pot incubation study was conducted to investigate the performance of widely used organic amendments, such as compost, vermicompost, charcoal, and newly used leaf powders of Sesbania acculeata and Typha elephantina on the proliferation of spinach in sandy loam soil. The results obtained from organic amendments were compared with those obtained from conventional fertilizers (urea, triple superphosphate, and muriate of potash). Leaves of S. acculeata and T. elephantina were found to be excellent nitrogen (N) providers (3.15% and 1.86%, respectively), with relatively low contents of phosphorous (P) and potassium (K). The spinach growing in vermicompost- amended soil presented the highest weights of both fresh and dry roots. Additionally, spinach presented the greatest degree of fresh shoot development, whereas the second highest degree of dry shoot development in S. acculeata leaf- amended soil. The newly used T. elephantina leaf amendment significantly improved soil fertility after 30 days of incubation. Tests of postharvest soils revealed that all the organic amendments used in the current study improved soil fertility and plant development far more than the control and traditional fertilizers did by increasing the organic conteat (OC) content, cation exchange capacity, and nutritional status, which is the ultimate criterion for sustainable agriculture.
