Book Description
Corn was grown in the Coastal Plain at Midville, Georgia in 1970, 1971, and 1972 to (1) compare silage production and quality when planted at a normal date (mid-April) with that planted late to coincide with wheat harvest (June 1 ), and (2) to determine how hybrid maturity, plant population, and irrigation influence the response to planting date. The results cam be summarized as follow... 1. Highest mean dry forage yields were obtained from the normal planting date compared to the late date. The use of either short-or full-season hybrids, higher plant population, or irrigation did not over-come the yield loss due to late planting. 2. Forage quality measured by in vitro dry matter digestibility (IVDMD) was higher for the normal planting date as compared to the late date. This was due to higher ear and lower stalk percentages in the early planted forage. IVDMD decreased with increased plant populations at the late planting date in the irrigated experimental due to an increase in stalk content. Ear content was higher in the short-season hybrid and did not decrease as the population increased as compared to the full-season hybrid. 3. Although not copared statistically, mean yields and IVDMD were higher in the irrigated experiment than the non-irrigated experiment. These results indicate that altering management pratices did not improve production and quality of late planted corn to a level comparable to the normal planting date.

Book Description
This experiment was conducted during the 1999 and 2000 growing seasons at the Iowa State University Sorenson Farm located southwest of Ames, Iowa and at the Iowa State University North Central Research and Demonstration Farm located south of Kanawha, Iowa. The experimental design for both locations was a randomized complete block with a split-split-split plot design and three replications of each treatment. Treatments included three planting dates, three hybrids, two row spacings, and two fertility regimes. Whole plot treatment was planting date and split plot treatments were hybrid, row spacing, and fertility regime. Significant difference was found between row spacing treatments for yield with the June planting dates in 1999 with 38-cm row spacing yielding more than 76-cm row spacing. Significant difference was not found between row spacing treatments for yield at the other planting dates in 1999 or in 2000. As planting date was delayed, weight kernel−1 decreased at both locations in both years. Starter fertilizer produced significantly higher yields in 1999, with a cold and wet spring, but not in 2000 with a warm and dry spring. Producers should rely on calendar date recommendations in determining optimum planting date. Planting dates between late April to early May should result in maximum yields in most years. Starter fertilizer may provide benefits during a cold and wet spring as well in situations of a low soil test for P or K.

Book Description
Ensiling is a technique that is used to store food, mainly vegetable crops, to feed the herd when the forage supply from the pastures is not enough to maintain the productive performance of the ruminant animals. However, silage can also be used as substrate for biogas production and other different purposes. In the past years, we have seen many advances in the knowledge about silage production utilization, and this book is a compilation and discussion of the outstanding scientific research activities concerning actually the most recent advances and technologies that have been studied about silage and future demands. It is directed to a broad public of readers - farmers, academics, students, or anyone just curious or interested in the subject.
