| Abstract | ||||
| Two field experiments were conducted at Sids research station, BeniSuef Governorate during 2014 and 2015 seasons, to study the effect of three manure levels (M1= zero, M2= 10 and M3= 20 m3 fed-1) and four nitrogen (N) application times (T1= 1/5 N at planting, 2/5 N at 1st irrigation and 2/5 N at 2nd irrigation, T2= 1/5 N at planting, 2/5 N at 1st irrigation and 2/5 N at 3rd irrigation, T3= 1/3 N at 1st irrigation, 1/3 N at 2nd irrigation and 1/3 N at 3rd irrigation and T4= 1/2 N at 1st irrigation and 1/2 N at 2nd irrigation) on white corn (hybride single cross 130) growth, yield components and grain yield. The resultant corn grains were estimated with respect to some physicochemical and technological properties. Manure levels and N application times significantly affected days to 50% tasseling, plant and ear height, ear length, rows per ear and kernels per row in both seasons. Manure levels significantly affected days to 50% silking in season 2015 while, N application times significantly varied days to 50% silking, grain yield in both seasons and earbdiameter in season 2015. The highest grain yield was obtained with M3 in both seasons while, T2 reached floweringbstage earlier than the other N application times and it had the highest value in plant ear height, yield components and grain yield. Results of interaction indicated that M3 had the highest grain yield when it was used with T2. 1000-grain weight significantly increased with increasing manure levels. M3T2 and M3T3 had the highest values in 1000-grain weight for both seasons. The endosperm and germ percentages were significantly increased in M3T2 and M3T3. Protein, ash, iron and zinc slightly higher in season 2014 at different manure levels. While, fat contents were higher in season 2015. Protein digestibility and availability of iron and zinc increased with increasing manure levels in both seasons. The lightness (L*) values of muffins crumb color insignificantly decreased while, yellowness (b*) values increased with increasing manure levels. In general, it could be concluded that, corn flour could be used to produce good quality gluten-free muffins with acceptable physical and sensory characteristics. | ||||
