| Description | Crop production is based on the photosynthetic process. Effective cropping systems are only attainable by optimising the size, active duration and effectivity of the photosynthesizing leaf canopy in the field. The extent of photosynthesis on a farm scale is impressive. A typical maize crop on one hectare of land utilises approximately 20 t. carbon dioxide, which is recovered from as much as 60 000 t. of air. Even highly productive cropping systems convert available radiation from the sun into chemical energy with an efficiency of less than 5%. Dramatic increases in crop yields may be attained in future, as has been the case in the past, as the process of photosynthesis is exploited with increasing skill. Gewasproduksie is gebaseer op die fotosinteseproses en produksieprogramme is siegs effektief indien die grootte, produksieperiode en doeltreffendheid van die groen, fotosintetiserende “fabriek” daardeur verbeter word. Die omvang van fotosintese op plaasskaal neem geweldige afmetings aan. Vir ’n tipiese mielie-oes op een hektaar land word nagenoeg 20 t. koolsuurgas benodig, wat uit sowat 60 000 t. lug herwin moet word. Selfs in hoogproduserende gewasstelsels word egter minder as 5% van die straling wat vanaf die son beskikbaar is, vasgelê in die vorm van chemiese energie. Soos in die verlede sal groot verhogings in oesopbrengste waarskynlik in die toekoms behaal word namate die fotosinteseproses beter verstaan en ontgin word. | |
