La Plata, like all cities, based its territorial organization -and landscape- on the construction of an inhabited area surrounded by productive green rings. Subsequently, like all other urbanizations, growth by extension generated a fragmented and degraded periphery. Currently, the periurban area presents a growing demand, dispute and conflict between different social groups that is beginning to be included in the political and management agenda. The purpose of this paper is to contribute to the construction of a new management model to transform the periurban area into a green belt, as an environmental, economic and social asset for the whole society.

Objectives: An experiment was designed with the objectives of studying the effect of acidity (pH) on the seed germination performance of Swiss-chard, and to determine the optimal pH level for the highest seed germination. Methods: The study was carried out in the laboratory of the Department of Horticulture of the University of Wolkite. The treatments were different pH levels (2, 4, 6 and 7) obtained from solutions of citric acid and distilled water in different concentration mixtures. The CRD design was used with three replicates. Findings: Analysis of variance (ANOVA) showed that all recorded germination parameters (germination rate, mean germination time, germination speed and germination index) were all most significantly different (p<0.001) for different pH levels. The highest seed germination rates (85.33% and 81.33%) were recorded at pH 7 and pH 6 respectively. Similarly the highest mean germination time (13 days and 11 days) and the highest germination speed (3.88/day and 3.7/day) were recorded at pH 6 and pH 7, respectively. However, the lowest seed germination rate (4%), the lowest mean germination time (0.5 days) and the lowest seed germination speed (0.18/day) at pH 2. The highest germination index (100 and 95.42) was recorded at pH 7 and pH 6 respectively while the lowest seed germination index (4.61) was recorded at pH 2. In general pH 7 and pH 6 can give the best results to the highest germination yield of Swiss chard.

The Cacao Frosty Pod Rot (Moniliophthora roreri (Cif. & Par.) Evans et al)1 is a disease with the greatest impact on cacao crop yields in Central and South America. It was recently detected in the state of Acre, Brazil. Although its control has been proven in various ways, cultural control has been checked to be the most effective and economical. The proposed model is based on the recognition of the critical states of the fruits as sources of infection, the disease cycle, the timely removal of diseased fruits and their free disposal on the soil.

Food waste is a problem that affects the food security of Mexican households, increases the erosion of ecological, social, and economic resources, and puts greater pressure on production systems, supply chains and consumers. Among members of society, the waste or discard of perishable products of agricultural origin, linked to intentional or unintentional human behavior and negligence, is in the last links of the food chain. The waste or discard of perishable products of agricultural origin, linked to human behavior and negligence, with or without intentionality, is located at the bottom of the food chain. It is the members of the household who waste the water-soil-energy resources used in food production. The Food and Agriculture Organization of the United Nations (FAO) estimates that 17% of total food production worldwide is wasted; of this, 61% corresponds to households, with fruits and vegetables being the most important, representing 45% of the waste. The development of new practices associated with the reduction of food waste in households are key to the development of strategies that allow the gradual reduction of losses and contribute to the fulfillment of goal 12 of the Sustainable Development Goals (SDGs) for 2030. The proposal to group different preservation methods, based on the differentiation of fruits and vegetables by organ of consumption in the home, will promote affordable options that contribute to the reduction of waste in households, improve food security, strengthen the household economy, and reduce the ecological impact caused by irresponsible consumption.

Mango anthracnose in mango in the tropical and subtropical regions of Mexico is a disease that induces serious economic losses, caused by Colletotrichum gloesporioides. The objective of this research was to determine the efficiency of integrated management for anthracnose control and to identify the critical moment for disease management. The work was carried out on cv. 'Ataúlfo', in Guerrero, Mexico, in three production cycles. The identification of the pathogen was confirmed and during a period of 11 months the abundance of spores in the canopy of the trees was examined. Three treatments were evaluated: integrated management with severe pruning (MIM-Pruning), integrated management without severe pruning (MIM) and Control treatment. The climate was conducive to the development of the disease (>80% incidence). The greatest increase in spores, with 65.9 to 84.1 spores/week, was observed during summer vegetative growth, in the phase of flowering and fruit set on the rachis, with its subsequent decrease in fruit growth. The MIM-Pruning and MIM treatment showed consistent results of less area under the disease curve progress (AUDCP), in foliage and flowering, causing a greater definitive fruit set per inflorescence and marketable fruits per tree with respect to the Control (P ≤0.05). Field pathogen population management should begin with the spraying of fungicide products in the summer vegetative growth phase and before the full flowering stage. Pruning is a practice that should be included in anthracnose management.

Leachate is among the main pollutants in landfills, specifically because its components can cause danger to the environment. One of the treatment options is phytoremediation, which is an efficient technique with low environmental impact and reduced costs. The potential for phytoremediation of heavy metals in plants exposed to Urban Solid Waste leachate from a final disposal site located in Tabasco, Mexico was evaluated. Five plant species predominant in the landfill coverage were selected and identified: Pennisetum purpureum, Cyperus esculentus, Canna indica, Dactylotenium scindicun and Echinochloa colona. Subsequently, leachate samples were collected from each plant and adjacent soil for determination of Heavy Metals through ICP-OES (n=3). The metals with the highest concentration in the leachate were Ba and Zn. Independently of the species, Barium was absorbed at a higher concentration. The higher Bioconcentration Factor was observed in Thallium by D. scindicum and C. indica, and the Translocation Factor identified hyperaccumulating species: E. colona (Zing and Barium) C. indica (Zing and Barium), P. purpureum (Thallium) and D. scindicum (Barium and Thallium).

Microgreens are relatively novel food with high nutrition and dietary benefits that can be influenced by the growing medium. Two experiments were performed to develop an optimum media for microgreensfrom kale (Brassica oleracea L. var. acephala), Swiss chard (Betavulgaris var. cicla), arugula (Eruca vesicaria ssp. sativa), and amaranth (Amaranthus tricolour L.). Experiment 1 was screening of media T1 = 30% vermicast + 40% sawdust + 30% perlite; T2 = 30% vermicast + 50% sawdust + 20% perlite; T3 = 50% vermicast + 30% sawdust + 20% perlite; T4 = 30% vermicast + 40% sawdust + 30% mushroom compost; T5 = 30% vermicast + 20% sawdust + 20% perlite + 30% mushroom compost; and a negative control (NC) = 50% sawdust + 50% mushroom compost. The positive control was Promix BX™ potting mix alone. Experiment 2 was to test the efficacy of two different sources of mushroom compost (White oyster mushroom compost (MC1) and Shiitake mushroom compost (MC2)) added to media T1 to T5 above. The results showed that the media physicochemical properties varied across treatments. Higher chemical parameters were obtained for T4, T5, and media containing MC1. Porosity and water retention were increased in media containing MC2 compared to the other.Seed germination, plant height, and microgreen yield were statistically (P>0.05) enhanced by T2 and T4 that contained MC2 compared to the rest. Microgreens yield was approximately three times higher in T2 and 4 with added MC2, except the yield of arugula which was two times higher in these media compared to the control. Overall, T5 alone, and T2 and T4 with added MC2 were the most effective media for microgreen production. Future studies will assess microgreens’ nutrients in different media.

Mexico is considered one of the main vegetable producing countries, however, its production is affected by several phytopathogens, whose control of these pathogens is based on the use of agrochemicals, which cause consequent environmental and health damages. In 2018, Mexico ranked 5th in the world in the consumption of fungicides and bactericides in agriculture. For this reason, new alternatives to control phytopathogens are important, with natural compounds with antifungal properties such as chitosan, a biopolymer of N-acetyl-D-glucosamine and D-glucosamine units linked by β-(1-4) bonds derived from the deacetylation of chitin with alkalysis (NaOH) or enzymatic hydrolysis. Chitosan is extracted from exoskeletons of arthropods. Research shows that it inhibits the growth of phytopathogens, due to its polycationic nature depending on molecular weight and deacetylation percentage. With other antifungal properties, they are inducer of phytoalexins, promotion of plant growth and biostimulant of beneficial microorganisms, due to its useful and economic potential agricultural application in technological innovation.
墨西哥被认为是主要的蔬菜生产国之一，然而，其生产受到几种植物病原体的影响，其对这些病原体的控制是基于使用农用化学品，从而造成环境和健康损害。2018年，墨西哥农业杀菌剂和杀菌剂消费量排名世界第五。因此，控制植物病原体的新替代品是很重要的，如具有抗真菌特性的天然化合物，如壳聚糖，n -乙酰- d -氨基葡萄糖和d -氨基葡萄糖单元由β-(1-4)键连接的生物聚合物，这些键是由碱法(NaOH)或酶水解甲壳素的去乙酰化产生的。壳聚糖是从节肢动物的外骨骼中提取的。研究表明，它抑制植物病原体的生长，由于其多阳离子性质取决于分子量和去乙酰化百分比。由于具有其他抗真菌特性，它们是植物抗毒素的诱导剂，促进植物生长和有益微生物的生物刺激素，由于其在农业技术创新中的有用和经济潜力。

Jingzhou city is well-knowing for its ancient historical, massive cultural, and river system ramified. To understand the actual status of road greenery in Old Town, three typical roads, Quyuan South Road, Wude Road, and Jiang Jin Road, were sifted and divided into nine plots (Quyuan South Road, Wude Road a, Wude Road b, Wude Road c, Wude Road d, Jiang Jin Xi Road). Indexes of species abundance, Shannon-Weiner, Simpson, and Pielou were employed to dissect the road belt community. Results showed that the community diversity was higher in plant structure complicated than only shrubs arrangement. The ideal road plots were Jiangjin West Road, sections a and b of Wude Road based on the evaluation results of the above indexes and actual effects of sunshade, seasonal changes, and ecological function. The shortcomings of the investigational road uncovered the existing problems. Too much attention has been paid to the ornamental effects to lower the importance of ecological function and the utilizing comfort of citizens. Therefore, the urban road greenery should combine the environmental function and aesthetic needs, and regular maintenance management should be timely and scientific.
