Utilization of maize stover to the production of meat and milk and saving the grains for human consumption would be one strategy for the optimal usage of resources. Variance and tendency analyses were applied to find the optimal nitrogen (N) fertilization dose (0, 100, 145, 190, 240, and 290 kg/ha) for forage (F), stover (S), cob (C), and grain (G) yields, as well as the optimal grain-to-forage, cob-to-forage, and cob-to-stover ratios (G:F, C:F, and C:S, respectively). The study was performed in central Mexico (20.691389° N and −101.259722° W, 1740 m a.m.s.l.; Cwa (Köppen), 699 mm annual precipitation; alluvial soils). N-190 and N-240 improved the individual yields and ratios the most. Linear and quadratic models for CDM, GDM, and G:F ratio had coefficients of determination (R2) of 0.20–0.46 (p < 0.03). Cubic showed R2 = 0.30–0.72 (p < 0.02), and the best models were for CDM, GDM, and the G:F, C:F, and C:S DM ratios (R2 = 0.60–0.72; p < 0.0002). Neither SHB nor SDM negatively correlated with CDM or GDM (r = 0.23–0.48; p < 0.0001). Excess of N had negative effects on forage, stover, cobs, and grains yields, but optimal N fertilization increased the proportion of the G:F, C:F, and C:S ratios, as well as the SHB and SDM yields, without negative effects on grain production.

Maize Stover

In the last decade, an increasingly common method of maize stover management is to use it for energy generation, including anaerobic digestion for biogas production. Therefore, the aim of this study was to provide a chemical and structural characterization of maize stover fractions and, based on these parameters, to evaluate the potential application of these fractions, including forbiogas production. In the study, maize stover fractions, including cobs, husks, leaves and stalks, were used. The biomass samples were characterized by infrared spectroscopy (FTIR), X-ray diffraction and analysis of elemental composition. Among all maize stover fractions, stalks showed the highest C:N ratio, degree of crystallinity and cellulose and lignin contents. The high crystallinity index of stalks (38%) is associated with their high cellulose content (44.87%). FTIR analysis showed that the spectrum of maize stalks is characterized by the highest intensity of bands at 1512 cm−1 and 1384 cm−1, which are the characteristic bands of lignin and cellulose. Obtained results indicate that the maize stover fraction has an influence on the chemical and structural parameters. Moreover, presented results indicate that stalks are characterized by the most favorable chemical parameters for biogas production.

An investigation of the production and utilization of crop residues for ruminant feeding in five villages within Aliero Local Government Area of Kebbi State was carried out using a structured questioner which was administered to 75 respondents. The data collected was analyzed by using simple statistical tool such as frequency distribution and percentage. The study revealed that 47.95% of the respondents were farmers with more than half (52.41%) had 5-8 members in their family. Mixed farming is common to all the respondents with cereal and legumes crops combination alongside with cattle, sheep, and goats rearing. Some crop residues such as maize stover, rice straw, etc are available all year round since they are generated both at rainy and dry season in the study area. Maize/sorghum/millet stovers and groundnut/cowpea straws plays a major part in ruminant feeding in the study area. The level of cultivation, production and utilization of crop residues as observed in this study depends on the land size, season of production and flock size amongst others. Most of the respondents (39.74%) source their crop residues from self-production and the type of crop residues are those from groundnut/cowpea straws, maize/millet/sorghum stovers and rice straws. The present study revealed the potential of crop residues not only as ruminant feeding but also as a means of livelihood among the respondents.
