The forage, wood and seed production of six Sesbania sesban accessions was assessed under irrigated conditions for two cutting frequencies and heights. Control trees were left uncut to measure their seed production potential. The trial was conducted over an 18-month period. The fastest growing ac...

The genus Stylosanthes contains about 30 species of which most are native to South and Central America, except for S. erecta and S. fruticosa which are native to Africa. The seven major species that have been used as livestock feed have been widely collected and their germplasm stored in genebank...

The reproductive biology of Sesbania sesban, S. goetzei and S. keniensis was studied. On average, flowering started after 123 (+16) days in S. sesban; 150 (+16) days in S. keniensis; and after 116 (+19) days in S. goetzei. A crossing experiment showed that S. sesban and S. goetzei are both self- ...

Aqueous acetone extracts of mature leaves from 10 accessions of two species of Sesbania plants were prepared and anlysed by high-performance liquid chromatography (HPLC). The HPLC phenolic profiles were used to develop a classification rule to distinguish between accessions. Out of the 44 mature ...

The samatic chromosome number in Sesbania in Sesbania sesban var. nubica, S. goetzei and S. keniensis (Leguminosae; papilionoidae) was found to be 2n=12. These findings were in agreement with earlier reports on S. sesban and S. keniensis. The chronomosome number 2n=12 is a new record for S. goetz...

A collection of 108 accessions of Sesbania sesban (Fabacea, Papilionoideae) was grown in the field and classified using morphological attributes. Numerical analysis resulted in the division of the collection into 2 major groups, which corresponded to the different varieties that exist in the subs...

A collection of Sesbania sesban accessions was grown out in the field and classified using real and standardised values of 10 agronomic attributes. Clustering the accessions using the observed values of the attributes produced several groups which were mainly based on the dry matter yields after ...
