Cinnamon and citronella essential oils in the in vitro control of the fungi Aspergillus sp. and Sclerotinia sclerotiorum

Among the fungi that cause damage and/or are spread by seeds, Aspergillus sp. and Sclerotinia sclerotiorum stand out, which have a worldwide distribution and a wide range of hosts. A viable and safer option than chemicals would be to use natural compounds for plant disease management. The objective of this study was to evaluate cinnamon (Cinnamomum cassia) and citronella (Cymbopogon winterianus) essential oils in the in...

Combined agronomic and climatic approaches for sorghum adaptation in Mali

In Sub-Saharan Africa, Genotype-Environment interaction plays a key role in formulating strategies for crop improvement. Multi-location trials have created enabling structure to determine varieties yield performance and stability. Crop modeling led to prediction of long-term and spatial effects of climate variability. Three improved varieties were compared to three landraces. Optimum cultivation areas minimizing the...

Critical variables for estimating productivity in maize as a function of plant population and spacing

The objective of this study was to find a group of independent variables that would influence and estimate maize (Zea mays L.) productivity, modeled by multiple linear regression. For that, an experimental delinquency in random order was used in a 2 × 2 factorial scheme, from two populations (45,000 and 65,000 ha-1 plants) and two spacings (0.45 and 0.90 m), with 20 replicates. Soil attributes and maize production...

Welfare effect of eliminating commodity price volatility: Evidence from Tanzania coffee farmers

This paper investigated the welfare consequences of reducing coffee price volatility in Tanzania. GARCH (1,1) model is fitted with monthly coffee prices from 1998 to 2017 to estimate the conditional and unconditional variance of the residual. The coefficient of relative risk aversion and unconditional variance of GARCH (1,1) model are applied in a typical Lucas-like representative argent model to examine the welfare...

Production performance evaluation of Koekoek chickens at Adami Tulu research center

A study was conducted to evaluate the production performance of koekoek chickens at Adami Tulu Research Center. Feed consumption, age at point of laying, annual egg production, mortality, and egg quality parameters were used as evaluation parameters. Mean feed consumption of starter, grower and layer of koekoek chickens at Adami Tulu Research Center was 56.4±4.6, 84.3±6.3 and 124±8.6 g/day,...

Rural public policies and the state of smallholders: Recent evidence from Brazil

The aim of this article is to characterize the current situation of family farmers or smallholders in Brazil and establish a connection with the rural public policies that exist in the country. This study analyzed the most current available data regarding family farming in Brazil, which included almost 4.7 million smallholders and their characteristics. Two analytical tools for unsupervised learning were combined,...
