Book Synopsis The 1944 Iowa Corn Yield Test by : Francis Reiss
Download or read book The 1944 Iowa Corn Yield Test written by Francis Reiss and published by . This book was released on 1945 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Each year the Iowa Farmer has a multitude of corn hybrids from which he can choose seed for planting. Some are well established strains of proven worth while others are new and relatively untried. It is impossible to determine, from the appearance of the seed in the bag, the desirability of any particular hybrid. The real test of its value is determined by planting it along with other hybrids to check its field performance. The Iowa Corn Yield test attempts to provide comparable performance records on a number of hybrids. It is believed that the information presented in this bulletin should afford a reliable comparison of the relative performance of various hybrids when grown in different parts of the state. Data are presented on each entry for yield, stand moisture, root and stalk lodging, ear height, dropped ears and damaged corn. A performance score has been used in evaluating the relative agronomic value of the various hybrids tested." -- p. [473]

Download or read book Economics of Research and Innovation in Agriculture written by Petra Moser and published by University of Chicago Press. This book was released on 2021-10-08 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The challenges facing agriculture are plenty. Along with the world's growing population and diminishing amounts of water and arable land, the gradual increase in severe weather presents new challenges and imperatives for producing new, more resilient crops to feed a more crowded planet in the twenty-first century. Innovation has historically helped agriculture keep pace with earth's social, population, and ecological changes. In the last 50 years, mechanical, biological, and chemical innovations have more than doubled agricultural output while barely changing input quantities. The ample investment behind these innovations was available because of a high rate of return: a 2007 paper found that the median ROI in agriculture was 45 percent between 1965 and 2005. This landscape has changed. Today many of the world's wealthier countries have scaled back their share of GDP devoted to agricultural R&D amid evidence of diminishing returns. Universities, which have historically been a major source of agricultural innovation, increasingly depend on funding from industry rather than government to fund their research. As Upton Sinclair wrote of the effects industry influences, "It is difficult to get a man to understand something when his salary depends upon his not understanding it." In this volume of the NBER Conference Report series, editor Petra Moser offers an empirical, applied-economic framework to the different elements of agricultural R&D, particularly as they relate to the shift from public to private funding. Individual chapters examine the sources of agricultural knowledge and investigate challenges for measuring the returns to the adoption of new agricultural technologies, examine knowledge spillovers from universities to agricultural innovation, and explore interactions between university engagement and scientific productivity. Additional analysis of agricultural venture capital point to it as an emerging and future source of resource in this essential domain"--
