Rice Harvest in Ceylon

Crop management techniques to enhance harvest index in rice.

A major challenge in rice (Oryza sativa L.) production is to enhance water use efficiency (WUE) and maintain or even increase grain yield. WUE, if defined as the biomass accumulation over water consumed, may be fairly constant for a given species in given climate. WUE can be enhanced by less irrigation. However, such enhancement is largely a trade-off against lower biomass production. If WUE is...

Pterygium in Ceylon.

The geographical situation of Ceylon led Cameron (I965) to suggest that the pterygium rate there would range from 5-5 to over io per cent., but the actual incidence appears to be much less for reasons which are discussed below. The incidence of pterygium has not been closely studied, first perhaps because it rarely causes blindness, secondly because the world's earliest eye hospitals were situa...

Childhood in Ceylon

Lead poisoning in childhood has been reported mainly from Japan, France, the United States, Great Britain, and Australia. Attention is drawn in this paper to the incidence of lead intoxication in childhood in Ceylon, seen and diagnosed within the past three years. Whereas in past reports the principal mode of lead intoxication in childhood has been from ingestion, in the present series inhalati...
