Proximate composition<br />
Proximate analysis showed that the cowpea varieties with the highest crude protein<br />
content were IT97K499-8 (26.12%) IT99K-7212-2-1 (26%) and Tumaini (25.95%)<br />
Varieties with lowest iron included IT00K-1207 (22.01%) and TZA 263 (22.6%). For<br />
fats, IT97K499-8 (11.18%), IT99K-7212-2-1 (10.98%) and Fahari (10.33%) varieties had<br />
the highest levels while the lowest included IT97K819-118 (8.17%) and IT96D-733<br />
(8.34%). Highest fibre was observed in TZA 263 (17.2%) followed by IT97K819-118<br />
(16.1%). The lowest in fibre were IT97K499-38 (12.34%), IT99K-7212-2-1 (12.53%)<br />
and VULI 2 (13.1%). Among the best new lines with regards to crude protein and fats<br />
content were IT97K499-8 and IT99K-7212-2-1.<br />
