Proximate composition of selected groundnut varieties and their susceptibility to Trogoderma granarium Everts attack

The proximate composition including moisture content, crude fat, crude protein and ash were determined for six groundnut varieties. Moisture content was highest (8.9%) in SAMNUT 19 followed by SAMNUT 23(8.6%) and was lowest (6.6%) in EX-DAKAR while ash ranged from 3.0% in RRB to 7.4% in RMP-91. The crude protein was highest (31.3%) in EX - DAKAR and lowest (19.7%) in SAMNUT 19. RRB had the highest crude fat of 53.1%...

Biological control of rot-inducing fungi of water yam (Dioscorea alata) with Trichoderma harzianum, Pseudomonas syringae and Pseudomonas chlororaphis

Potential of Trichoderma harzianum, Pseudomonas syringae and Pseudomonas chlororaphis for the control of rot in post harvest yams was investigated. Treatments comprising two pathogenic fungi, each paired with three biological antagonists were set up. Degree of rot was evaluated by calculation of percentage reduction by the antagonists. Pathogenicity test showed that Botryodiplodia...
