摘要：Grains of ten maize varieties grown in NWFP, Pakistan were obtained and investigated for physicochemical characteristics, proximate composition , energy content and mineral composition. Mean electrical conductivity and thousand seed mass were determined in the range of 9.26-33.83 μS and 319-230.4 g, respectively. Proximate composition shows moisture content in the range of 9.201-10.908%, ash (0.7-1.3%), fats (3.21-7.71%), protein (7.71-14.60%), crude fiber (0.80-2.32%) and carbohydrates (69.659-74.549%). The data indicate that seeds of these varieties vary greatly in term of protein, fats and crude fiber contents. Pahari, Jalal 2003, WD- 2*8 and Azam varieties were determined to contain high protein content (>10% protein) while WD-2*8, Pop. 2004B, PSEV 3-2 and Sarhad (W) contain high fats content of >6%. The energy value of the grains of these varieties was determined in the range of 307.047-394.066 kcal/100 g which shows that the grains of these varieties are rich source of energy. In minerals the level of sodium is 540.30-620.41ppm, K (2915-3471 ppm), Ca (410-590 ppm), Fe (38.02-56.14 ppm), Zn (37.05-52.4 ppm), Mg (985.2-1125.3 ppm) and Cu (11.02-14.25 ppm).
