and comment to both practical farmers and agricultural investigators as well. Strange as it may seem, however, there has been practically no work done to discover why the maize plant, or any other grain normally bisexual, should be sterile. Many theories have...

treatments upon the humus content of Missouri soils two lines of experiment were carried out. First, a study of the effect of crop rotation and manures upon the humus and nitrogen content of soils as evidenced in the rotation plats of the Missouri Experiment...

In the past twenty-five years much experimental work has been done with cowpeas, in relation to cultural methods, fertilization, and variety tests, but practically nothing has been written with regard to the direct effect ...

and water quality and given rise to non-point source pollutants. The claypan soil region of Missouri has a high runoff potential that increases the possibility of transport of non-point source pollutants to downstream sites. The Agricultural Policy...

The U.S. Department of Agriculture initiated the Conservation Effects Assessment Project in 2003 to quantify water quality and wildlife benefits of conservation programs funded by the 2002 Farm Security and Rural Investment Act. This study examined...

of the ear and kernel which have a marked influence upon the yield. This is so universal that we have score cards which set forth the ideal type of ear and give certain values to the different characters. In general, the score cards are alike and all agree...

To evaluate the effects of municipal wastewater effluent (WWE) and Missouri River water (MOR) as irrigation sources on soil chemistry, seed banks, and microorganisms, a field study was conducted in conjunction with a set of greenhouse studies...

Development of improved management practices to increase nitrogen use efficiency (NUE) within agricultural fields is needed to improve crop production and reduce nitrogen (N) loss. Field studies planted to maize were conducted in 2005 and 2006...

sorption and column leaching experiments were performed using soils collected from cropland (crop), grass vegetative buffer strips (VBS), and riparian VBS. Single-point, solid-to-solution partition coefficients (Kd) were determined by reacting soil...

This investigation was undertaken in order that something might be learned concerning: (a) the cost of maintenance of live weight in ungrown cattle; (b) the effect of a maintenance ration upon the condition of ungrown ...

, and microbial community and structure; (2) compare ecosystem response to changing climatic conditions between Northern (Nebraska) and Southern (Texas) playa soils; and (3) assess effectsof increased agricultural nitrogen inputs on playa plant communities...

climate stations in the region; the period examined for this study was 1982-2006. Days with measurable precipitation were treated as a gamma distribution in order to determine the top 2%, 1%, and 0.5% to define events as unusual, rare, and extreme...

Disease control in plant agriculture is largely achieved through application of various antimicrobials. Manipulation of indigenous soil microbial communities received attention as it promises improved pathogen control and enhanced plant outputs...

Due to changes in climate and socioeconomic developments, current soil management practices in the Bolivian Andean Highlands may be increasing soil degradation thereby threatening food security. A study was established in ...

The use of anionic polyacrylamide (PAM) as a soil amendment is an emerging conservation practice. However, guidelines have not been developed with considerations of soil properties and topographic characteristics. The ...

of stockpiled tall fescue. Others have predicted that liming will increase P and decrease aluminum (Al) availability to plants in the types of soils used in this study. Study sites were located at the University of Missouri's Southwest Center (SWC) and Bradford...
