Abstract:
Cowpea (<em>Vigna unguiculata</em>) is an inexpensive, nutrient dense legume favoring health. Physical characteristics and nutritional composition of Pusa Komal (PK) was compared with improved grain cowpea varieties (PL-1, PL-2, PL-3, PL-4, PL-5, PGCP-11 and PGCP-13). Grain cowpea varieties were significantly larger in size, higher seed weight, higher hydration and swelling capacity than PK. PGCP-13 and PL-3 were significantly denser seeds than PK (1.167g/ml). Bulk density of grain cowpea varieties (0.714 - 0.76 g/ml) was significantly lower than PK (0.812g/ml). Leaching losses in PL-1, PL-4, PL-5 and PGCP-13 (11.72 -12.26 %) was significantly lower than PK (13.65%). The proximate composition of PK viz. ash (4.02%), crude fat (1.04%), crude protein (24.4%), crude fiber (3.63%) and carbohydrate (66.91%) were significantly lower in comparison to different grain cowpea varieties. Phytate content was significantly low in PGCP-11, PL-4 and PL-3 (ranged from 184.77 to 203.31 mg/100g) than PK (204.24 mg/100g). The tannic acid content of PL-1, PGCP-13 and PL-3 was significantly lower than PK (0.68%).
