Book Description
Growing winter cereal grains in the North Central U.S. can provide multiple benefits to the current corn (Zea mays L.)/soybean [Glycine max (L.) Merr.] rotation. Intercropping red clover (Trifolium pratense L.) with winter cereal grains can also benefit the cropping rotation by producing forage, contributing nitrogen (N) to subsequent crops, and enhancing soil quality. This cereal grain/red clover intercropping study was conducted during the 2002-03 and 2003-04 growing seasons to determine the best seeding rates for maximizing cereal grain and red clover yields by optimizing resource competition in the intercrop. In March, red clover was frost-seeded at 0, 300, 600, 900, 1200, and 1500 seeds m−2 into winter wheat (Triticum aestivum L.) and triticale (X Triticosecale Wittmack) seeded at 100, 200, 300, and 400 seeds m−2 the previous October. Cereal grain yield, grain yield components, red clover densities, red clover dry matter (DM), forage quality, and late-spring soil N03-N were measured. When examined across species and year, 300 seeds m−2 cereal grain seeding rate was optimum for grain yield and suitable for red clover establishment. Red clover plant densities at cereal grain harvest were 10 to 22% of the seeding rates. Red clover harvests in the late summer, early fall, and following spring resulted in total DM production of 6 to 8 Mg ha−1. In 2004, red clover DM crude protein (CP) and in vitro dry matter digestibility (IVDMD) increased of 10 and 5% and neutral detergent fiber (NDF) decreased 9% as cereal grain seeding rates increased from 100 to 400 seeds m−2. Forage quality also increased in both study years as red clover seeding rates decreased, but in both forage quality situations the differences were minor. In one study year, soil NO3-N concentrations were slightly greater than the no clover treatment when red clover seeding rates were>900 seeds m−2. The results suggested a winter cereal grain/red clover intercrop could be successfully established in the North Central U.S. using a winter cereal grain seeding rate of 300 seeds m−2 and red clover seeding rates between 900 to 1200 seeds m−2 with minor changes in red clover forage quality and soil NO3-N.

Book Description
Kura clover (Trifolium ambiguum M. Bieb.) is slow to establish and has low seed yields the year after establishment. Intercropping a cereal grain during clover seed field establishment could provide additional revenue to seed growers, provided that intercropping did not jeopardize future clover seed yields. Factorial combinations of spring- and fall-planted kura clover monocultured, companion-intercropped with wheat (Triticum aestivum L.) at two row widths, and relay-intercropped with wheat at two row widths were compared. Spring-planted clover established better than fall-planted clover as measured by percent ground cover. Both spring- and fall-planted kura clover were better established when relay-intercropped than when companion-intercropped. Spring-planted kura clover relay intercropped with fall wheat established better than any other treatment combinations, comparing favorably with spring-planted kura clover monocultures at 18 months from planting. Kura clover generally did not affect wheat yields. Wide and narrow row spaced wheat generally affected kura clover similarly, with narrow-spaced wheat out yielding wide-spaced wheat. It was concluded that relay-intercropping fall wheat into spring-planted clover does not adversely affect clover establishment and could therefore provide more cash revenue than monocultured clover during the clover establishment period.

Book Description
This book is open access under a CC BY 4.0 license. This book provides a fresh, updated and science-based perspective on the current status and prospects of the diverse array of topics related to the potato, and was written by distinguished scientists with hands-on global experience in research aspects related to potato. The potato is the third most important global food crop in terms of consumption. Being the only vegetatively propagated species among the world’s main five staple crops creates both issues and opportunities for the potato: on the one hand, this constrains the speed of its geographic expansion and its options for international commercialization and distribution when compared with commodity crops such as maize, wheat or rice. On the other, it provides an effective insulation against speculation and unforeseen spikes in commodity prices, since the potato does not represent a good traded on global markets. These two factors highlight the underappreciated and underrated role of the potato as a dependable nutrition security crop, one that can mitigate turmoil in world food supply and demand and political instability in some developing countries. Increasingly, the global role of the potato has expanded from a profitable crop in developing countries to a crop providing income and nutrition security in developing ones. This book will appeal to academics and students of crop sciences, but also policy makers and other stakeholders involved in the potato and its contribution to humankind’s food security.

Book Description
With the recent decline of the European honey bee, it is more important than ever to encourage the activity of other native pollinators to keep your flowers beautiful and your grains and produce plentiful. In Attracting Native Pollinators, you’ll find ideas for building nesting structures and creating a welcoming habitat for an array of diverse pollinators that includes not only bees, but butterflies, moths, and more. Take action and protect North America’s food supply for the future, while at the same time enjoying a happily bustling landscape.

Book Description
This book examines the literature on red clover since about 1985. In each of the 17 chapters, an effort was made to summarize the earlier literature and to integrate the recent findings into this background. The timing is appropriate with the present interest in sustainable agriculture, in which red clover was so prominent in the past. This is the first book to be published which deals solely with this important forage species. Audience: Primarily scientists and scientifically trained technicians who will appreciate an up-to-date summary on red clover.
