Early planting and relay cropping: pathways to cope with heat and drought?
(2021-05-05)
Maize (Zea mays) is an important food and cash crop of uplands in Southeast Asia, where it is often prone to drought and heat stress associated with climate change. This study aimed at assessing the effect of heat and drought on maize performance, testing coping strategies under such weather extremes, and understanding associated mechanisms. The experiment was carried out during 2018 in Thailand, using a split-plot design with three replications. Treatments were: July-planted maize sole cropping (control), July-planted ...

Analysis of the nutritional and productive behaviour of dairy cows under three rotation bands of pastures, Pichincha, Ecuador
(2021-12-08)
This research was carried out on Pennisetum clandestinum-based pastures to identify the effect of three (3) types of stocking methods with similar forage allowance (8.2 kg of dry matter for 100 kg of live weight) but differing by the occupation times of the rotations (3 h, 24 h, and continuous) on the behaviour and the production of dairy cows. The experimental scheme consisted in three herds of four Holstein Friesian cows grazing three paddocks, one per rotation type, for one week and replicated three times in a ...

Forage diversity and fertiliser adoption in Napier grass production among smallholder dairy farmers in Kenya
(2021-11-10)
Feed scarcity is one of the major challenges affecting smallholder dairy production in Kenya. Forages are the foundation of livestock nutritional requirements; forage diversification and fertiliser are intensification options that can increase productivity. A sample of 316 and 313 smallholder farmers were surveyed in eastern midlands and central highlands of Kenya, respectively, to establish the types of forages cultivated and the factors that influence fertiliser adoption in Napier grass (Cenchrus purpureus Schumach.) ...

Factors for the success of agricultural cooperatives in Brazil
(2021-02-25)
The Brazilian cooperative agribusiness is in a transitional phase. This moment is marked by the advancement of market globalisation, which has exerted great competitive pressure on national agribusiness. To survive and thrive in a globalised and fiercely competitive environment, cooperatives must face new challenges in the pursuit of competitiveness. This study aimed to identify and describe the main success or failure factors affecting agricultural cooperatives. To this end, bibliographic research was used as a ...

Optimisation of the seedball technology for sorghum production under nutrient limitations
(2021-04-13)
The seedball technology is a simple and affordable seed-pelleting technique that uses locally available materials such as sand, loam, wood ash and seeds to enhance early crop establishment. It has been shown to be effective for pearl millet (Pennisetum glaucum) subsistence production in Sahelian environments. The objective of this study was to optimise the seedball technology for sorghum (Sorghum bicolor (L.) Moench) under greenhouse conditions. Series of pot experiments were conducted in order to identify optimal ...

Determinants of protected tomato production technologies among smallholder peri-urban producers in Kiambu, Kenya
(2021-03-05)
Climate variability and the rise in incidences of pests and diseases continue to undermine production of high value vegetables among smallholder farmers in sub-Saharan Africa. In order to respond to these challenges, protected farming technologies (PFT) (such as greenhouses) which modify the plant environment and therefore aid in avoiding the harmful eects of climatic factors have been promoted. Greenhouses protect the crops against high solar radiation and heavy rainfall that have the potential of destroying vulnerable ...

Litter characteristics of pine shavings, bio-secure pine shavings and sunflower hulls and its impact on broiler performance
(2021-02-22)
The aim of this study was to investigate the physical characteristics of three litter materials, namely pine shavings (PS), bio-secure, fumigated pine shavings (BS) and sunflower hulls (SH) and its influence on broiler performance over a 33-day production cycle. The experiment was conducted in commercial poultry houses holding 42,500 chicks each, utilising a randomised block design with six house replicates per treatment. Litter samples were collected weekly for analyses of moisture, water-holding capacity, bulk ...

A review of soil fertility management communication in sub-Saharan Afrika
(2021-02-12)
In sub-Saharan Africa (SSA), declining soil fertility is among the factors a ecting optimal food production. Although a number of interventions have been implemented to improve soil fertility management (SFM) in SSA, their adoption especially among small scale farmers has been low. Although the literature provides considerable evidence of socioeconomic factors which influence adoption, the subject of how communication influences adoption of SFM remains under-explored. This paper therefore reviewed studies on SFM ...
