Transpiration and crop yields
1958
de Wit, C.T.
Theoretical and practical aspects of the transpiration of crops in the field are discussed and he concludes that the relationship between transpiration and total dry matter production is much less affected by growing conditions than has been supposed. In semi-arid and arid regions, this relationship depends on plant species and on free water evaporation, while in cloudy regions it depends mainly on plant species. This difference is due to light intensity; in cloudy regions assimilation is less than in regions with more bright sunshine. The relationship between transpiration and dry matter in plants grown in the field with limited available water is often similar to that for container-grown plants. Where water is not limited, however, transpiration tends to increase, although even when transpiration becomes considerably greater than free water evaporation, the relationship between transpiration and production in the field resembles that of plants growing in containers. The relationship between transpiration and total dry matter production is not affected by the ability of plants to withstand periods of drought, but the amount of marketable product and total amount of water which is transpired during the growing period may depend largely on their drought resistance.

SynopsisPhosphorus, dry matter, nitrogen, magnesium, potassium and calcium accumulation by the mature corn plant grown under conditions of decreasing soil moisture supply were 40, 44, 50, 65, 71 and 93%, respectively, of the values obtained for the mature corn plant produced with adequate moisture throughout the growing season.

1958
Linz, Juan
For various stated reasons, the parties that are neither religious nor class- or function-based have escaped scholarly attention. These laic-bourgeois parties have been important in themselves and in the meaning that their failure may hold for European democracy. The growing religious split in Euro pean parties also needs study.
