Download or read book Managing Cover Crops Profitably 3rd Ed written by Andy Clark and published by DIANE Publishing. This book was released on 2008-07 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cover crops slow erosion, improve soil, smother weeds, enhance nutrient and moisture availability, help control many pests and bring a host of other benefits to your farm. At the same time, they can reduce costs, increase profits and even create new sources of income. You¿ll reap dividends on your cover crop investments for years, since their benefits accumulate over the long term. This book will help you find which ones are right for you. Captures farmer and other research results from the past ten years. The authors verified the info. from the 2nd ed., added new results and updated farmer profiles and research data, and added 2 chap. Includes maps and charts, detailed narratives about individual cover crop species, and chap. about aspects of cover cropping.

Available in PDF, EPUB and Kindle. Book excerpt: Some consideration has been given to the irrigation of winter wheat in the Willamette Valley of Oregon. This important crop has yielded quite well since the development and introduction of the stiff-strawed, semi-dwarf wheats, but, because of the usually dry early summers, it has been suggested that irrigation of winter wheat could probably increase the yield still further. The objective of this study was to determine the response of winter wheat to supplemental irrigation when grown under various levels of spring applied nitrogen on two important soil series. Moisture changes in the soil were followed in late spring and early summer as another phase of the study. Two winter wheat varieties were sown in October 1966 at two locations in the Willamette Valley. Each variety received supplemental nitrogen in the early spring and irrigation in late May or in June. Grain was harvested about August 1 and the yield in bushels per acre was determined. Soil moisture changes were studied at the same two locations with the use of gypsum blocks buried in the soil at different depths and at another location by soil core samples. Readings from the gypsum blocks were converted to percent moisture in the soil by a series of calculations. Based on the increase of grain yields under the various treatments, the use of nitrogen fertilizer appears to be a more practical means of increasing grain yields than does irrigation. Only a slight response to irrigation was noted. Decrease in moisture content of the soil occurred particularly in the top four feet. The largest moisture decrease occurred in the top foot, the next largest decrease was in the second foot, then the third foot, and then the fourth foot. Some moisture decrease was noted below four feet; however, the amount of decrease was small. It appears from the limited observations that soils in the Willamette Valley contain enough moisture for wheat to complete its development with little or no moisture stress.

Download or read book Plant Rhizobia Symbiosis and Nitrogen Fixation in Legumes written by and published by Frontiers Media SA. This book was released on 2024-04-29 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: The reciprocal exchange of chemical signals between legume and rhizobium leads to the establishment of Root Nodule Symbiosis (RNS). The discoveries of the Nodulation Factor (NF) and nod genes, along with the discoveries of the relevant genetic plant factors, have expanded our understanding of how legume-rhizobial interactions constitute a successful mutualistic symbiosis. Symbiotic nodule formation can be divided into the following molecular events: (i) the reciprocal exchange of signals; (ii) epidermal recognition of symbiotic partner and infection thread formation; (iii) nodule organogenesis; (iv) the establishment of a microaerophilic environment to provide nitrogenase the ideal condition to work; and, (v) modulation of immunity to host rhizobium inside the nodule cells. The number of nodules in a plant is maintained via a process of systemic signaling, known as ‘autoregulation of nodulation’ (AON), that acts as a negative signal to control nodule number in low nitrogen conditions and inhibit nodule initiation in an optimally nitrogen-fed plant. Over 200 plant genes have been discovered up to now and these discoveries have given us a broad understanding of RNS.
