Abstract:
... Intensive study for more than 100 yr has resulted in a good understanding of corn's (Zea mays L.) growth and development. However, abnormal development of ears in corn was reported in several U.S. states, including Texas, Colorado, Kansas, Nebraska, Iowa, and Illinois, during 2016, stretching our understanding. A comprehensive review of the literature was conducted to identify abnormal ears’ sympt ...

Abstract:
... This study aimed to investigate the silage quality, bacterial community, and predicted functional profiles during the ensiling of whole‐crop maize (Zea mays L.). Maize was harvested at dough stage and ensiled in laboratory‐scale silos (1‐L capacity). Triplicate silos were sampled after 1, 3, 7, 15, 30, and 60 d of ensiling. The bacterial communities on Day 3 and Day 60 were assessed through high t ...

Abstract:
... Evolution of herbicide resistance in weeds is a serious threat for sustainable crop production. There were reports of poor control of toothed dock (Rumex dentatus L.) with metsulfuron‐methyl herbicide, an acetolactate synthase (ALS) inhibitor used in wheat (Triticum aestivum L.) at farmers’ fields in Northwest India. Two‐year greenhouse and field studies were conducted to (a) determine the level o ...
