Economic evaluation of biological nitrogen fixation in flooded rice cultivation in subtropical lowlands
(2023-06-13)
This study aimed to assess the economic viability of biological nitrogen fixation in flood rice cultivation in subtropical lowlands. A field experiment of seven treatments was carried out during the cropping seasons 2015/16, 2017/18, 2018/19 and 2019/20 at the Lowland Experimental Station of Embrapa, in Pelotas, RS, Brazil. The evaluated treatments were: (1) negative control (without N and inoculant); (2) positive control with recommended N-fertilization (120 kg N ha-¹, without inoculant) (standard recommendation); ...

Effect of Fermentation on the bioactive compound of cocoa Beans: a systematic review and meta-analysis approach
(2023-05-30)
Several studies have found the effect of cocoa bean fermentation on bioactive compounds through various fermentation characteristics; however, none of these studies adopted the meta-analysis approach. The effect of cocoa bean fermentation on six bioactive compounds: epicatechin, catechin, total phenolic content (TPC), anthocyanins, theobromine, and caffeine were systematically reviewed. This study aims to determine which variables that can affect the loss of bioactive compounds during fermentation so that their ...

Identification of fungal pathogens causing postharvest rot of bulb onions (Allium cepa L.) in selected major growing regions of Kenya
(2023-06-27)
Rot is a major cause of bulb onion losses in Kenya, accounting for about 14 % of total postharvest losses. In Kenya, the fungi associated with bulb onion postharvest rot of onion postharvest rots are not well known. Therefore, this study aimed at identifying the fungal pathogens contributing to bulb onion postharvest rot in major growing regions of Kenya. Bulb onion samples were collected from seven major markets and isolates were obtained by cutting 3 mm tissue segments from the edges of rotten lesions. These were ...

Measuring the economic performance of smallholder organic maize farms; Implications for food safety and security
(2023-05-31)
The use of chemical inputs in conventional agriculture is associated with some health and environmental issues. This led to a call for more sustainable and environmentally friendly agriculture with no health issues. However, there is low participation in organic farming in Nigeria, which could be linked to less knowledge about its profitability. The study investigated smallholder organic maize farming profitability in Northern Nigeria. We employed descriptive statistics, profitability analysis, and a multiple regression ...

Stakeholders’ knowledge of organic rice quality in Indonesia
(2023-05-31)
In recent years, the demand for organic rice has increased along with the increasing consumer awareness of it. However, information or knowledge systems regarding consumer expectations of the quality of organic rice have not been well developed. For this reason, this study aims to describe gaps in information or knowledge systems throughout the supply chain which is the strategy for developing the quality of organic rice. Focus group discussions were conducted with farmers, processors, and consumers, from which key ...

Measuring of Social Sustainability Through Community Perceptions for Prima Certified Fruit Development in East Java
(2023-06-20)
The multidimensional perspective of ecological and social sustainable agriculture in the global agri-food system has resulted in the emergence of certification schemes as an important mode of governance, but there are still few agricultural actors in Indonesia who register for product certification and recertification. The purpose of this research is to analyze community perception in order to determine the development of Prima certified fruits in East Java. The sampling technique used quota sampling, with 5 people ...

Estimation of growth parameters in Brahman cattle from Mexico
(2023)
The objectives were to evaluate non-linear models (NLM) to define the growth curve of Brahman cattle in Mexico. The database was derived from weight development control, with live weight measurements (150,932 in females and 286,804 in males) taken in the interval from birth to 1095 days of age. Four NLM were evaluated: Brody, Bertalanffy, Gompertz and Logistic. The selection of the NLM with the best adjustment was made based on the Akaike and Bayesian information criteria. Growth parameters were generated: adult ...

Investigating the efficacy of common agricultural practices for the management of fall armyworm (Spodoptera frugiperda (J.E. Smith)) on cereal crops
(2023-07)
In Benin, the fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), is the most important polyphagous noctuid pest. This study aimed to assess the impact of agricultural practices on the abundance of this pest and determine whether its feeding preference and larval development differ among four cereal types. First, we conducted a descriptive survey of 80 farmers randomly selected for farm visits and oral interviews using a structured questionnaire to ascertain their preferred agricultural practices ...

Market-driven harvesting of non-timber forest products and the governance of communal forests in the south-east lowveld of Zimbabwe.
(2023-07)
Despite forests providing a wide range of important products and services for much of Zimbabwe’s population, natural forests are threatened by deforestation. The highest rates of deforestation occur in communal forests. Communal forest resources in Zimbabwe show evidence of increased degradation and signs of a breakdown of local institutions for resources management. These signs of a breakdown of local institutions are coupled with evidence of a lack of any emerging alternative institutions for conservation of forest ...

Hotspot 17 der biologischen Vielfalt - Konzeption zur Förderung der biologischen Vielfalt in der Region „Werratal mit Hohem Meißner und Kaufunger Wald“
(2023)
Im Rahmen des Projektes „Schaf schafft Landschaft“ wurde von Oktober 2019 bis April 2022 eine Konzeption zur Förderung der biologischen Vielfalt in der Region „Werratal mit Hohem Meißner und Kaufunger Wald“ (Hotspot 17) erarbeitet. Bei dieser Hotspotkonzeption wurde ein überregionaler, umsetzungsorientierter Ansatz verfolgt und die gesamte Region des Hotspot 17 in den Blick genommen, um möglichst umfassend die Themen mit besonderer naturschutzfachlicher Relevanz für den Erhalt der Biodiversität zu erkennen und mit ...
