Abstract Determination of gene effects and combining abilities is a critical stage in maize hybrid breeding. In the present study, 20 S6 lines as female and three S6 inbred lines (K18, K19 and K1264/5-1) as tester were crossed and the resulting  test cross progenies were evaluated in a randomized complete block design with three replications in 2008. During the growing period, several agronomi...

Maize is an ideal forage crop for ensilage because of its high levels fermentable carbohydrates, although it low in protein. Sunn hemp a legume with crude protein content potential to be used combination maize provide silage higher content. Different percentages sunn hemp-maize mixtures 80-20, 60-40, 40-60 and 20-80 respectively were compared silages sole hemp. In the laboratory study, DLG clas...

Introduction Challenges of increasing population, decreasing land availability and quality, and demand for biobased products require continuing to increase our food, feed, forage and feedstock supply in a safe and sustainable manner while simultaneously decreasing agricultural inputs. Yields of crops such as maize (Zea mays L., corn) have dramatically increased in the US to meet these needs wit...

Studies at the University of Reading (UK) compared silage quality, feed intake and digestibility of maize silage with maize±sun ̄ower (MS), maize±kale (MK) and maize±runner bean (MRB) silage, when sun ̄owers, kale and runner beans represented 26, 7 and 16% of total silage dry matter (DM). All intercrop silages had higher crude protein values (MS, 137 g kgÿ1, MRB, 120 g kgÿ1, MK, 105 g kgÿ1) than ...

Maize silage is forage of high quality and yield, and represents the second most important use of maize in the United States. The Wisconsin Quality Synthetic (WQS) maize population has undergone five cycles of recurrent selection for silage yield and composition, resulting in a genetically improved population. The application of high-density molecular markers allows breeders and geneticists to ...

Intercropping of silage maize (Zea mays L.) and alfalfa (Medicago sativa is not a common practice because generally reduces grain biomass yield. The objective this research was to evaluate the productivity profitability maize–alfalfa intercropping, with goal establish increase in first year production. experiment conducted Fargo Prosper, ND, USA, 2014–2017. design randomized complete block four...

For the long-term sustainability of the dairy industry in the Northeastern USA, manure nutrient application rates should not exceed crop nutrient removal once aboveoptimum soil fertility levels are reached. Dairy producers have shown a growing interest in brown midrib (BMR) forage sorghum (Sorghum bicolor (L.) Moench.) · sudangrass (Sorghum sudanense Piper) hybrids (S · S) as a more environment...
