Pigeons foraged for large, preferred grains of maize and smaller, unpreferred grains of wheat presented in bowls covered with sawdust.
Therefore, organic manures specifically, farm yard manure, fisheries manure, and press mud along with Zn foliar and soil fertilization can influence the availability of Zn to shoot and grains of maize crop.
Intact and steam-flaked grains of maize, wheat and rice (with whole hulls) were analyzed for chemical composition, starch gelatinization degree (SGD) and in vitro fermentation characteristics to investigate the influence of cereal type and steam-flaking (SF) processing on their nutritive values.
In many cases where causal mutations have been identified, such as non-shattering in rice cultivars, free threshing or naked seeds in barley, and naked grains of maize, a single mutation primarily controls a domestication transition, i.e., one gene for one domestication trait [23].
Boer et al. (2007) reported that most of the detected QTL controlling grain yield and grain moisture of maize were influenced by temperature differences during critical stages of the growth.
Furthermore, two genes possibly involved in IAA synthesis were associated with grain yield, indicating that the auxin signaling pathway could directly contribute to grain yield of maize hybrids throughout cell expansion.
Workayehu (2000) also reported that grain yield of maize increase progressively with added nitrogen fertilizer up to a certain rate.
Fosu-Mensah (2012) reported increased variability in grain yield of maize as a result of increased variability of rainfall.
This clearly demonstrated that organic manures' addition and Zn soil and foliar application have pronounced effects on grain yield of maize crop.
