Effect of salt stress on muskmelon (Cucumis melo L.) seeds
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 ...
Socio-economic aspects of irrigation agriculture as livelihood for rural families in Brazil’s semi-arid northeast
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 ...
Quality of black bean seeds harvested with different moisture contents and submitted to two different storage systems
Bean (Phaseolus vulgaris L.) is one of the main foods of the Brazilian diet. However, to achieve high yields, one of the determining factors is seed quality, which can be influenced by harvesting time and storage. The objective of this work was to evaluate the physical quality and physiological performance of black bean seeds as function of the moisture content at harvest and storage method. For that, black bean seeds, cultivar BRS Campeiro, were used. The harvest was performed when the seeds reached moisture contents ...
Assessment of a pragmatic strategy to improve health of kacang goats in subsistence agricultural communities in Indonesian Borneo
Poverty limits options available to smallholder, subsistence farmers to prevent or reverse livestock malnutrition and endoparasitism, two of the global drivers of goat morbidity and mortality in resource-constrained, tropical, agricultural communities. Our first study objectives describe changes observed in body condition and anaemia after implementation of three feasible and simple husbandry changes to improve health of smallholder herds of kacang goats in rural, Indonesian Borneo. These changes included routine ...
Biofuels and livelihoods: Empirical findings on the welfare impacts of Jatropha cultivation in the Mangochi district, Southern Malawi
This study evaluates the welfare impacts of jatropha (Jatropha carcus) cultivation measured as consumption expenditure per adult-equivalent for smallholders in southern Malawi. Household survey data from the southern region of Malawi collected in 2014 from 303 smallholders using purposive and random selection strategies were used. Propensity score matching and endogenous switching regression methods were employed to address the selection bias problem and to control for observed and unobserved covariate effects. The ...
Constraints to commercialisation of smallholder agriculture in Tanintharyi division, Myanmar
Myanmar is a country in rapid economic and political transition, with opportunities emerging for its smallholders to benefit from current economic growth. However many smallholders are trapped in semi-subsistence agriculture, disconnected from markets. Commercialisation can increase farm incomes, and - through the multiplier effect - lead to wider pro-poor growth in the rural economy. However, there are many constraints to commercialisation that prevent this process from occurring. While literature on constraints ...
Responses of Filipino farmers to harsh weather phenomena: A risk perception and attitude study
Small-scale farmers, whose livelihood and food security greatly depends on farming, are constantly exposed and vulnerable to the risks of extreme weather events. The current study explored how the perception and attitude on agricultural risks of small-scale farmers from the upland, lowland and waterside ecosystems in Siniloan, Laguna in Philippines influence the way they respond and cope with extreme weather events. The study employed quantitative and qualitative data collection methods particularly farm surveys, ...
The impact of uncertainty on smallholder farmers' income in Kyrgyzstan
The farming systems in the mountain areas of Kyrgyzstan are primarily characterised by small-scale crop and livestock activities. Farmers are faced with several environmental, socio-economic and political challenges and constraints that result in significant uncertainties affecting their operations. This paper attempts to model how various sources of uncertainty collectively affected the smallholders’ farm incomes during a mid-term horizon using Monte Carlo simulation. The analyses were based on data collected through ...
Competitive interaction between guava and weeds: Effect on initial growth
Guava (Psidium guajava L.) is one of the 50 most consumed fruits in the world. However, weed competition compromises fruit production in cultivation areas. Thus, this work aimed to evaluate the competitive interaction between guava plants and common infesting species on initial growth. Guava seedlings were cultivated during 60 days with Bidens subalternans DC., Waltheria indica L. or Commelina benghalensis L. in a randomized block design with four replicates. The experiment was conducted under greenhouse condition ...
Liming effects on reproductive growth and yield components of maize grown on an acid rainforest soil
Maize was planted on limed and unlimed plots to study the effect of soil acidity on reproductive growth and yield components of the crop in Owerri southeastern Nigeria. Eight (8) maize varieties (Factor A) and two lime levels (0 and 2 t ha-1, Factor B) were arranged as a factorial experiment in a randomised complete block design with three replications. The number of days to 50 % anthesis and silking, anthesis-silking interval (ASI), physiological maturity and grain filling duration were measured to determine the ...
