In order to assess the agronomic and economic feasibility of growing corn under reduced tillage using manure as a source of fertilizer, a study of silage and grain corn ( Zea mays L.) production using three levels of tillage (conventional, reduced and zero till) and two types of fertilizer ...
Effects of different diets and breed type on feedlot performance of 209 crossbred steer calves were evaluated in each of 2 yr during growing, finishing and total feedlot periods. Steers fed maize silage for a 16-wk growing phase gained faster and consumed less DM/unit gain than did calves fed...
For very specific reasons, the growth rates of per capita demand growth and population growth in this section differ from the descriptive statistics shown in Table 1. The decomposition in Table 1 was population-share-weighted for comparability with the existing literature, while the population growth...

Sensors for safety, such as ultrasonic, laser scanner, bumpers, were also not included in this study for the API platform not to further complicate the analysis, while they are very important for safety reasons In this matter, some additional costs should be expected depending on the diffusion ...
Three dairy farms that double cropped winter annuals and corn during the years of 2016 and 2017 were selected for the study. These farms were located in northern and western Pennsylvania, where the growing season was relatively short and soils were shallow. Based on the growing season for 2017...
The reasons can be summarized as follows. The decoupling degree equals 0.8 and is the division of the relationship between decoupling and coupling. The greater the extent the degree exceeds 0.8, the less desirable the decoupling status. Fig. 9 shows that the decoupling degree was almost over ...
Reasons for heterogeneity The heterogeneity of results presented in this review reflects the great diversity of socioeconomic and environmental contexts across which studies have been conducted over different periods of time. High heterogeneity across the studies, which represents a challenge to both CCFP...
