Poljodjelstvo u području strni i kukuruza Banovine Hrvatske: Proizvodnja, prehrana ljudi i stoke, radni i gnojidbeni odnosi

The work emphasizes the key place of small grains (wheat, barley, oats) and corn in the diet of people and livestock. Corn was a staple food for the peasant population and a key animal feed, while stubble was used for bread and other food products. Turina describes agrotechnical practices, including crop rotation, soil cultivation and fertilizer application, emphasizing the importance of manure and the early use of mineral fertilizers. He analyzes labor relations, pointing out the lack of mechanization and dependence on manual labor, which limited yields.

The book also addresses socioeconomic conditions: peasants often worked on small holdings, faced with low yields due to uneven soil quality and climatic challenges. Turina suggests improvements, such as better organization of cooperatives and education of farmers. He also highlights regional differences within the Banovina of Croatia, especially in Slavonia, where conditions for corn were more favorable.
