Abstract

Sweet potato is a dual-purpose crop, which could produce both food and feed. The vine pruning prior to storage root harvesting was intended to increase the quantity and quality of fresh forage for animal feed. This study aims to evaluate whether periodic pruning can affect the storage root yield and its starch content. This experiment employed split-plot design with two factors and three replications. The first factor as main plot was vine pruning which consisted of four distinct pruning times (four times, three times, twice and once). The second factor as sub-plot was cultivars which consisted of six dual-purpose cultivars and two controls. The storage root yields, vine yields, starch yields and the reduction in storage root yields were observed. The results showed that the vine pruning decreased the storage root yields, with small increases the vine yields. The percentage of the reduction in storage root yields were 4-58%, while the decrease vine yields are relatively inconsistent. The starch yield of the cultivars with one pruning time were in the range of 2.34-6.67 ton ha-1. On the contrary, the three times pruning or more since 80 days after transplanted can reduce the starch yields for more than 50%. The slight increase in vines yield due to pruning was followed by the decrease in storage root yields and starch content of the sweet potato.

Abstract

In Tunisia the main objective of sustainable agriculture is to improve agricultural systems by creating more wealth and meeting the needs of the population without compromising those of future generations. It turned out that confusion and lack of clarity of ownership status of agricultural land would lead to instability in agricultural sustainability by having a negative impact on social and economic prosperity and environment preservation. Within this environmental concern, the current research constitutes an assessment of the level of sustainability of different farms in Tunisia where problems of land ownership still exist. The current research is based on the Farm Sustainability Indicators method (standing for: ‘Indicateurs de durabilité des exploitations agricoles or IDEA). This case study employed IDEA method which provides operational content to compare the sustainability concept at the farm level, based on the factor of ‘land tenure status’. In Tunisia, the lack of clear land ownership affects the output of agriculture that is why it is valuable to assess the impact of land properties status on farms’ agricultural sustainability. Hence, we distinguished two groups of farms: Private Farms (PF) (inherited from father to son) and Farming Enhancement Corporation (FEC) (state’s lands leased by farmers for many years). The results showed that land tenure has impact on farms sustainability. PF are more sustainable on both agro-ecological scale (49.2) and socio-territorial scale (48); compared to FEC (agro-ecological: 44.5 and socio-territorial: 46). PF favor integrated systems and the production of field crops and fodder crops and they attach greater importance to their employees’ training.

Abstract

This research seeks to identify the potential of local community to support the development of productive landscape in Yogyakarta City. It hypothesizes the important roles of ecological perception, aesthetical perception, economics perception of productive plant, social-cultural perception, the role of social organization and the status of house ownership that would assist productive landscape development. This paper contributes to the importance of productive landscape development through community participation. The road/street location was chosen with purposive sampling by considering the characteristics of the arterial roads and local streets. Five arterial roads and five local streets were determined as the locations. The field survey method, with semi-structured questionnaires, was employed to obtain the primary data. The residences in arterial roads and local streets were selected by the linear systematic random sampling and the respondents participating in this study were 160 persons.  The results have shown that the perception of residents depends on the experiences of their situation. The majority of residents have disclosed the low response on economical perception of productive landscape development in the greenery. The development of productive landscape is influenced by the ecological, aesthetical and socio-cultural perceptions of the residents living nearby the arterial roads. Meanwhile, the residents of local streets have a different perception of productive landscape development, which is influenced by ecological and aesthetical perceptions. The collaboration between government and community should be made to develop the efforts to grow and manage the vegetations along the roadsides of the city.

Abstract

Soya bean is an important economic crop for smallholder farming systems in Upper West Region of Ghana. In spite of the introduction of modern and improved soya bean production technologies in Ghana, the productivity of the crop in the region is still low. Given that inefficient use of resources is a potential course of low yields, this study analyses the resource use efficiency of soya bean production. Using cross-sectional data collected from 271 soya bean farmers from the Upper West Region of Ghana, the study employed the Stochastic Frontier Translog Production Function as well as the ratio of Marginal Value Product to Marginal Factor Cost to understand the resource use efficiency of soya bean farmers in the region. The empirical results showed that the estimated coefficients of soya bean seeds, labor and farm size were significant and positively related to soya bean output even though fertilizer input was surprisingly significantly and negatively related to the output of soya bean. Also, resources employed in soya bean production were found not to be efficiently utilized as they were underutilized, indicating that yield and profit could be improved with optimal use of production inputs. Finally, the paper revealed that access to soya bean threshers is the most important constraint faced by farmers in the region. For the region’s soya bean yield to be improved, government and development organizations should assist soya bean farmers by removing major bottlenecks to acquisition of resources required for the production and postharvest handling of the crop.

Abstract

Cocoa is one of Nigeria’s most important agricultural commodities due to its status as a source of foreign exchange earnings. However, low quality and hence low patronage of cocoa beans of Nigeria origin has reduced this fortune in recent years due mainly to non-adherence to Good Agricultural Practices (GAP) among farmers. The study therefore identified the determinants of compliance to GAP among cocoa farmers in Ondo State, Nigeria. A three-stage sampling procedure was used to select 20% (150) of cocoa farmers across randomly sampled cocoa-producing communities in Ondo State. Information was sourced using a well-structured, validated questionnaire. Data were analyzed using frequency counts, mean and Ordinary Least Square (OLS). Majority of farmers had good knowledge of GAP. However, farmers were mostly faced with constraints such as high cost of agrochemicals and labor scarcity. Farmers rated economic benefits of GAP as high; while health and environmental benefits were rated low; with high acceptability of cocoa; utilization of soil organic matter and prevention of respiratory malfunctioning identified as top economic, environmental and health benefits, respectively. Although the general compliance was high across different GAP, practices to which farmers were least compliant were however of relatively high economic, health and environmental implications. Knowledge, perceived health and perceived economic benefits of GAP were important determinants of compliance. The extension unit of the Ondo State Ministry of Agriculture should prioritize sensitization and education of farmers on the economic, health and environmental benefits of GAP of cocoa in order to ensure profitability and sustainability of production.

Abstract

Weeds are a major problem in crop cultivation, either in food crops, horticulture, plantations or forests and cause a decrease in the quality and quantity of production. Weed biocontrol, especially by using plant pathogenic fungi, has received attention but is still lacking in application. The purpose of this study was to determine the potential of Fusarium sp. and Chaetomium sp. as biological control agents against five broad-leaf weeds (Asystasia gangetica L., Ageratum conyzoides L., Synendrella nodiflora (L.) Gaertn., Wedelia trilobata (L.) U.S. Hitchc. and Amaranthus spinosus L.). The variables observed were the incubation period, disease incidence, disease intensity, as well as weed fresh and dry weight. The results of this study showed that the two pathogenic fungi, Fusarium sp. and Chaetomium sp., can cause a more intensive disease in A. conizoides than A. spinosus. A. gangetica, S. nodiflora and W. trilobata; however, the fungi have not been able to inhibit the growth and kill the weeds. Therefore, improvement need to be done by modifying the media to increase the ability of fungi to control weeds.

Abstract

This research aims to discover the psychological state of farmers in the agricultural cultivation of food crops during the COVID-19 pandemic. It is a descriptive explorative study which explores the farmers’ opinions regarding their agricultural activities during the COVID-19 pandemic which reached its peak between March and June 2020. During this period, a Large Scale Social Distancing (LSSD) system was enforced in some areas. The data collection was conducted in June 2020 before the implementation of the new normal, involving 634 respondents which spread across 40 districts throughout Java. Throughout the COVID-19 pandemic period, almost all farmers continued to carry out their agricultural activities. Some farmers had implemented the health protocols. According to most farmers’ opinions, doing the agricultural activities made them healthier. With regard to COVID-19, most farmers behave normally, while the rest feel worried. Agricultural extension activities are constrained and hampered by the implementation of physical and social distancing, especially large-scale social restrictions. Seeing the psychological condition of the farmers, where most are continuing to cultivate food crops and only slightly worried about the COVID-19 pandemic, gave hope for the sustainability of agricultural production in the new normal period.

Abstract

The problem of severe weed infestation often arises during the early phases of establishment of oil palm field due to the spacing requirement and growth habit of young oil palm plantation until later years when the canopy closes. This study was conducted at Ala, Akure-North Local Government Area, Ondo State, Nigeria, to investigate the composition of weed species and their distribution in fruit vegetable-juvenile oil palm intercrop. The fallow alleys within the immature oil palm were intercropped with 2 accessions of tomato (NGB 01665 and NG/AA/SEP/09/053) and eggplant (NGB 01737). The sampling of the weed species was carried out with a quadrat (0.25 m2). Weed species parameters and the Diversity Index (D) were quantitatively analyzed. The results revealed that members of Asteraceae and Poaceae gave the highest weed species at 3 and 6 weeks after intercropping (WAI) (17.857% and 19.04%) respectively. A total of 23 and 16 were found at 3 and 6 WAI, while the least diversity index of 0.734 was recorded in the immature oil palm/tomato (NGB 01665) plot at 6 WAI. Farmers should be persuaded to simultaneously intercrop fruit vegetables within the alley of juvenile oil palm, particularly at the earlier years prior to closure of the oil palm canopy.

Abstract

Basal plate rot or moler caused by Fusarium oxysporum f. sp. cepae (FOCe) is the most important disease of shallot. However, the information of crop losses attributed to the pathogen is still limited, especially related to resistance of shallot. This paper discusses the correlation between disease severity and resistance of some shallot varieties to yield losses. The experiment was arranged by Completely Randomized Design (CRD) with six varieties of shallot as treatments, each of which consisted of 20 shallots, with three times of replications. The independent variables were the disease severity of twisting leaf and rotting of shallot bulb. The association of disease severity versus yield losses in different varieties was based on the correlation analysis. The results showed that both variables were positively correlated to yield losses, which were significantly affected by the level of resistance. Yield losses in resistant and moderate varieties were at the ranges of 2.13-4.38 and 15, 27.26-40.04, respectively.

Abstract

Kekian is a processed product from fish meat added with seasoning, fillers and binders then formed and wrapped with tofu skin. Kekian has a low dietary fiber so that the addition of seaweed porridge can be used to increase the content of dietary fiber in kekian. The purpose of this study was to determine the effect of adding different seaweed porridge (Eucheuma cottonii) to characteristics of manyung (Arius thalassinus) kekian and determine the best seaweed porridge to the best kekian fish characteristics. The research method used was experimental laboratories using a completely randomized design of one factor is concentration of the addition of porridge (0%, 20%, 30% and 40%) with 3 replications. Sensory value data were analyzed by the Kruskal-Wallis test, while tests of dietary fiber, air content, protein content, water holding capacity and gel strength were analyzed using ANOVA. The results showed that the difference in the addition of seaweed porridge had a significant effect (P
