Effect of salt stress on muskmelon (Cucumis melo L.) seeds
(2019-12-16)
Cucumis melo is one of the most appreciated and consumed vegetables in the world, however, producing areas have been suffering from increased salinity in irrigation water. Therefore, accesses of melon, from the germplasm bank of the Federal Rural Semi-Arid University (UFERSA), were tested for salinity and the physiological responses of the seedlings were evaluated. For the 24 accesses of C. melo, salinity of 0.06 and 3.45 dS m-1 was applied. For this, four subsamples of 25 seeds per access were used, which were seeded ...

Seasonal variation in mycoflora associated with asymptomatic maize grain from small-holder farms in two provinces of South Africa
(2020-11-27)
Seed quality plays an important role in the establishment of healthy crop stands. The aim of this study was to identify the mycoflora associated with maize grain collected over two growing seasons, one experiencing severe drought, from small-holder farms across KwaZulu-Natal (KZN) and the Eastern Cape (EC), two important provinces with maize producing small-holder farmers in South Africa. Asymptomatic maize ears were collected at harvest during two maize growing seasons from farms located in Hlanganani (KZN), ...

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 ...

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 ...

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 ...

Socio-economic aspects of irrigation agriculture as livelihood for rural families in Brazil’s semi-arid northeast
(2019-12-04)
Along the lower-middle São Francisco River, in the semi-arid region of northeast Brazil, irrigated agriculture contributes to reduce rural poverty. In the framework of the Itaparica Reservoir construction, three irrigation schemes were implemented in the Pernambuco state to compensate the local population for flooded land. Despite favourable production conditions for irrigated agriculture, many smallholders in the irrigation schemes are facing poverty. To identify socio-economic key indicators on farm income, expert ...

Natural and land-use drivers of primary production in a highly vulnerable region of livestock production (Sierras del Este – Uruguay)
(2019-02-21)
Sierras del Este is one of the two regions in Uruguay that are most vulnerable to climate change. A relevant vulnerability factor is the variability of the natural grasslands’ productivity. The objective of this study was to analyse the role of natural and land use drivers on grassland productivity as an essential factor for increasing the adaptive capacity of livestock production and reducing their vulnerability to extreme climatic events. The period 2000–2015 was analysed using the aboveground net primary production ...

Income Diversification trough Animal Husbandry for Smallholder Vanilla Farmers in Madagascar
(2020-05-07)
The SAVA region in northeastern Madagascar is the largest vanilla producing area globally. Here, we investigated the role of animal husbandry (AH) for income diversification of small-scale vanilla farmers. To do this, 300 household heads were interviewed about livestock ownership, management and marketing. This information was complemented by data from 1800 households (HHs) on involvement in vanilla production (VP) and AH. Throughout the region, 83 % of HHs produced vanilla and 84 % kept livestock. Chicken-keeping ...

Does the non-farm sector affect production efficiency of the Vietnamese agricultural sector? A stochastic frontier production approach
(2020-12-24)
This study examines the impact of the non-farm sector on farm value-added and production efficiency in the Vietnamese agricultural sector by using data from the Vietnam Household Living Standard Survey 2012. Production function and stochastic frontier production analysis is used to determine the impact, and the instrumental variables method is applied to address endogeneity. We find that the Vietnamese non-farm sector has a positive effect on both farm value-added and efficiency. This result indicates that income ...
