Winter Wheat and Sorghum Production in the Southern Great Plains Under Limited Rainfall (Classic Reprint)


Book Description

Excerpt from Winter Wheat and Sorghum Production in the Southern Great Plains Under Limited Rainfall The crop failures and the spectacular dust storms that have ravaged the Great Plains during the last few years have focused public atten tion on the region and have aroused much speculation regarding its future for farming. This attention has been directed most closely to that portion consisting of southwestern Kansas, western Oklahoma, southeastern Colorado, and part of the Texas Panhandle. It is here that some of the worst soil blowing has taken place. Hasty judgment has led to condemnation of the whole area for crop production by some people, and its _no less vigorous support by others. N o intensive effort has been made to get at the facts and to determine from past experience what is likely to happen in the future. To understand better the present status of agriculture in this area it is necessary to have some knowledge of the changes that have taken place since its settlement.

Matured seed more often than other varieties, but were inferior in yield and sometimes in. Quality of forage to Red Amber (fig. Early Slimac, and other later maturing sorgos. Leoti Red, 3. Sorgo tested only from 1920 to 1922, now appears more promising than either Red Amber or Early Sumac, but more data are needed to determine its value definitely. Shoh varieties as mclean, Colman, Collier, and Red X matured too late in most seasons and Were of secondary value to Kansas Orange and Sumac in the class of relatively late varieties. These late varieties have a limited value for fodder production in western Kansas, but in many years are unfit for silage because they do not have time to mature before they are harvested.

Agriculture in Semi-Arid Environments


Book Description

The semi-arid zones of the world are fragile ecosystems which are being sub stantially modified by the activities of mankind. Increasing human populations have resulted in greater demands on semi-arid zones for providing human susten ance and the possibility that this may enhance desertification is a grave concern. These zones are harsh habitats for humans. The famines that resulted from drought during the late 1960's and the 1970's in the African Sahel illustrated the unreliability of present agricultural systems in this zone. Large fluctuations in ag ricultural production have occurred in semi-arid zones of Australia, North Ameri ca, and the Soviet Union due to periodic droughts, even though considerable ag ricultural technology has been devoted to agricultural development in these zones. The challenge to mankind is to manage these different semi-arid zones so that pro ductivity is increased and stabilized, and environmental deterioration is decreased. Irrigation can be used to increase and stabilize agricultural production in semi-arid zones as discussed in Volume 5 of this series, Arid Zone Irrigation. The present volume, Agriculture in Semi-Arid Environments, focuses on dryland farming in semi-arid zones, and is relevant to the large areas of the world where rainfall is limiting and where water is not available for irrigation. This volume is designed to assist agricultural development in these areas and consists of reviews and analyses of available information by scientists working in Africa, Australia, and at the U ni versity of California.




Perennial Crops for Food Security


Book Description

This publication presents the latest research in perennial crop breeding and programmes, and provides direction on where the field of perennial crop is heading. Many production systems and agricultural practices are no longer sustainable today as their effects on soils, water, biodiversity, and livelihood are significant. Mainstreaming the use of perennial crops into current practices can contribute to stabilize fragile soils and maintain natural processes essential to obtain stable and high yields. To face the challenges and risks of the twenty-first century, increasing the perenniality of crops and agricultural systems should become a larger research, development and policy focus.

A Revolution Down on the Farm


Book Description

At a time when food is becoming increasingly scarce in many parts of the world and food prices are skyrocketing, no industry is more important than agriculture. Humans have been farming for thousands of years, and yet agriculture has undergone more fundamental changes in the past 80 years than in the previous several centuries. In 1900, 30 million American farmers tilled the soil or tended livestock; today there are fewer than 4.5 million farmers who feed a population four times larger than it was at the beginning of the century. Fifty years ago, the planet could not have sustained a population of 6.5 billion; now, commercial and industrial agriculture ensure that millions will not die from starvation. Farmers are able to feed an exponentially growing planet because the greatest industrial revolution in history has occurred in agriculture since 1929, with U.S. farmers leading the way. Productivity on American farms has increased tenfold, even as most small farmers and tenants have been forced to find other work. Today, only 300,000 farms produce approximately ninety percent of the total output, and overproduction, largely subsidized by government programs and policies, has become the hallmark of modern agriculture. A Revolution Down on the Farm: The Transformation of American Agriculture since 1929 charts the profound changes in farming that have occurred during author Paul K. Conkin's lifetime. His personal experiences growing up on a small Tennessee farm complement compelling statistical data as he explores America's vast agricultural transformation and considers its social, political, and economic consequences. He examines the history of American agriculture, showing how New Deal innovations evolved into convoluted commodity programs following World War II. Conkin assesses the skills, new technologies, and government policies that helped transform farming in America and suggests how new legislation might affect farming in decades to come. Although the increased production and mechanization of farming has been an economic success story for Americans, the costs are becoming increasingly apparent. Small farmers are put out of business when they cannot compete with giant, non-diversified corporate farms. Caged chickens and hogs in factory-like facilities or confined dairy cattle require massive amounts of chemicals and hormones ultimately ingested by consumers. Fertilizers, new organic chemicals, manure disposal, and genetically modified seeds have introduced environmental problems that are still being discovered. A Revolution Down on the Farm concludes with an evaluation of farming in the twenty-first century and a distinctive meditation on alternatives to our present large scale, mechanized, subsidized, and fossil fuel and chemically dependent system.
