1949
Johnson, Sherman Ellsworth
This report is a revision of the summary of a study that was begun in the fall of 1944 with the same purpose of analyzing the changes in farming during the interwar and war years, appraising the forces back of the large increases in production, and evaluating some of their peacetime implications. The background data used for this analysis are largely the statistics contained in the crop and livestock reports and other production releases of the Bureau of Agricultural Economics. | This study was undertaken in the belief that a first requisite for intelligent action on our peacetime production problems is an understanding of the nature and strength f the forces that have shaped the course of agricultural production in the years to come.

Liberty Hyde Bailey
1949
Rodgers, Andrew Denny
Bailey is credited with being instrumental in starting agricultural extension services, the 4-H movement, the nature study movement, parcel post and rural electrification. He was considered the father of rural sociology and rural journalism. | Bailey represented an agrarianism that stood in the tradition of Thomas Jefferson. He had a vision of suffusing all higher education, including horticulture, with a spirit of public work and integrating "expert knowledge" into a broader context of democratic community action. As a leader of the Country Life Movement, he strove to preserve the American rural civilization, which he thought was a vital and wholesome alternative to the impersonal and corrupting city life. In contrast to other progressive thinkers at the time, he endorsed the family, which, he recognized, played a unique role in socialization. Especially the family farm had a benign influence as a natural cooperative unit where everybody had real duties and responsibilities. The independence it fostered made farmers "a natural correction against organization men, habitual reformers, and extremists". It was necessary to uphold fertility in order to maintain the welfare of future generations.

Magister meus Filippo Silvestri est auctoritas in entomologia Italiae, haud dubie, mundi qucque! In ejus aetate, nullus erat praestantior quam ille entemologista in respectu offertorii tum pro internatione tum pro humano genere, sive practice sive purifice in hoc mundo. lle natus est die 23 Iunii anno 1878, Factus fuit assistens magister St Antonio Berlese. Anno 1904 fuit princeps in Departumento investigaticnis de Zcologia agraria Portici. Anno 1920 fuit rector Collegii agriculturae Portici, Simul quoque R.

1949
Wenham, Hugh Trevor
An error in production has resulted in there being no page numbered p66, however no text is missing. | The available evidence suggests that speckled leaf blotch of wheat is increasing in severity in Canterbury. Prior to 1947 it was practically unknown in the province, but in November of that year a wheat crop at Lincoln College was found to have a high percentage infection. In November of 1948 a preliminary survey of wheat crops in North Canterbury was made by the writer, and of forty fields inspected, all except two were found to be infected. This evidence, together with the known potential importance of the disease as illustrated by the severity of attacks in overseas countries has emphasised the need for fundamental studies of the disease and its causal organism under New Zealand conditions. This thesis embodies the results of a two year study conducted at Canterbury Agricultural College, Lincoln, during 1948-49 and is intended to contribute to our understanding of the disease. The aims were 1. To isolate and prove pathogenicity of Septoria tritici Rob. as causal organism of speckled leaf blotch under Canterbury conditions. 2. To study signs and symptoms as they occur in the field and under glasshouse conditions. 3. To study the causal organism in pure culture. 4. To study host range of the causal organism in New Zealand. 5. To study varietal resistance to the disease in New Zealand wheats. 6. To determine the mode of perpetuation of the causal organism in New Zealand.
