In many African cities urban and peri-urban agriculture (UPA) plays a major role in creating jobs and contributing to food security. However, many small-scale UPA systems are characterised by excessive nutrient inputs to the livestock unit and poor handling of manure. To assess the impact of impr...

Climate change associated global warming, rise in carbon dioxide concentration and uncertainties in precipitation has profound implications on Indian agriculture. Maize (Zea mays L.), the third most important cereal crop in India, has a major role to play in countryメs food security. Thus, it is i...

The work reported in this paper was initiated to estimate the age at first calving in herd of Kenana cattle with particular reference to the influence of year and season of the birth on age of heifers at calving. It included a feeding trail to elucidate the effects of improved nutrition on body d...

Milk yield performances in Kenana and Butana cows were examined to determine the influence of age on production. The mean milk yields for the Kenana and Butana herds were 2136 ± 168 and 1807 ± 592 kg produced in a mean lactation period of 283 ± 40 days and 283 ± 57 days respectively. In both herd...

Adaptation options that address short-term climate variability are likely to lead to short-term benefits and will help to deal with future changes in climate in smallholder cropping systems in Sub-Saharan Africa (SSA). In this study we combined field experimentation and long-term rainfall analyse...

The South American monsoon system (SAMS) is the most important climatic feature in South America and is characterized by pronounced seasonality in precipitation during the austral summer. This study compares several statistical properties of daily gridded precipitation from different data (1998–2...
