AGRICULTURAL ENGINEERING TECHNOLOGY FOR MAIZE-GRAIN GROWING IN THE TROPICS AND SUBTROPICS

BOHUMIL HAVRLAND

Abstract
The agriculture misses a comprehensive document dealing with technological solutions for individual agricultural crops and providing basic technico-economic information about crop cultivation in existing technological levels. The above mentioned lack lead to the attempt to carry out AGRICULTURAL ENGINEERING TECHNOLOGICAL LEAFLETS (AETLs)* As the first the AETL for MAIZE-GRAIN was worked out on the base of four technological levels that are: Full-scope mechanized growingf Mechanized growing with a share of hand-tool operations, Animal traction growing with a share of hand-tool operations,, Hand-tool growing, as the most typical for agricultural regions of the Third World being the two latest ones mentioned above. The AETL methodology supposed to execute detailed analyses of all fixed technological levels with regard to the operations sequences and working processes. The economics and vitality of individual levels were expressed by reviewing the impacts of economic and exploation criteria? by putting-in the cost calculation sheet and by calculating of costs p&r working' hour as well as per hectare (in USD).

Key words:
animal traction growing technology, hand-tool growing technology, impact of economic criteria, technological level
