Currently, water users associations (WUAs) in semi-arid areas of southeastern Spain (Murcia region) send a multitude of data supplied by sensors in the field to the cloud. The constant technological revolution offers opportunities for small farms not to be abandoned, thanks to the Internet of Things (IoT). This technology allows them to continue to manage remotely using smartphones/tablets/laptops. This new system contributes to the mitigation of climate change from several aspects: reduction of water footprint and energy consumption (in the pumps that pressurize the grid, such as in the optimization of the proposed solution, by using batteries that communicate in low radiation of electric and magnetic alternating fields (LoRad), General Packet Radio Service (GPRS), or narrowband IoT (NB-IoT), or clean energy). The analysis of these data and the incorporation of new IoT technologies facilitate the maintenance of green roofs and ensure the continuity of these farms. The direct benefit obtained is remarkable CO2 removal that prevents desertification by the abandonment of arable land. This communication shows the implementation of a Smart Agri system in areas with micro-plots (surface less than 0.5 ha) with low-cost technology based on long-range (LoRa) systems, easily maintainable by personnel with basic knowledge of automation, which transforms into a very interesting solution for regions with development roads. In addition, complex orography and difficult access are added in both physical and technological environments. The main technical limitations found in such plots are poor coverage for mobile phones and unworkable and expensive implementation by wiring or WiFi/radio systems. Currently, thanks to the Smart Agri system implemented in this WUA in Murcia, farmers can manage and control the irrigation systems in their plots from home. Then, they cannot lose their crops and respect the isolation conditions imposed by the Spanish government as a result of the alarm caused by COVID-19.
Cocoa is one of the most significant assets in the ecuadorian agricultural structure, which also provides a good source of income for thousands of farmworker families. However, fertilization research works in cocoa cultivation have been relatively scarce. Decades of global research have shown that mycorrhizal fungi determine the fertilization and conservation of agrosystems. Fertilization is considered to be among the cultural and agricultural practices affecting mycorrhizas, which diminishes or prevents the fungal colonization. The objectives of research works were the following: the characterization of mycorrhiza species associated with cocoa, to determine the effects of nitrogen and phosphate fertilization in plant population and to identify the critical dose affecting the fungus development. A factorial design was used (AxBxC), with two (2) application systems, four (4) doses of nitrogen fertilizer, and two (2) doses of phosphate fertilizer with three repetitions. The turkey's test was used to evaluate means with confidence interval of 95%. The evaluated variables were: diameter and length of cocoa pods, number of cocoa pods per tree, index of cocoa beans and almond yield per hectare, as well as, mycorrhizal spore counting, percentage of mycorrhizal fungi colonization, visual density of endophyte, and characterization of mycorrhiza species. The results concluded that the application of 100 Kg/ha N + 70 kg/ha P in the system below the soil surface, achieved yield increments
The research was carried out on the Property “El Cartan” that is located in Km 4 way at Puebloviejo-Ventanas, county of Los Ríos. A test was conducted on the hybrid corn DK-1040. This test measures the response of the larvae of insects Spodoptera frugiperda and Elasmopalpus lignosellus to the application of dose of biological and organic insecticides. Also, the most appropriate dose in products was determined with an economic analysis. The experimental design used was random complete blocks with seven treatments and three replicates. The variables evaluated are: percentage of larvae control, number of larvae per plant, corn damage, and yield for hectare. The evaluated variables were subjected to the analysis of variance, and Tukey test was applied to 95 % probability. The analyzed results were determined to apply Neem (Azadirachtina indica) in dose of 1,0 L ha -1 . It diminishes the populations of S. frugiperda and E. lignosellus in relationship to the other active matters applied in the test. Higher doses lead to migration of pests to nearby hosts. The highest yield per hectare was found in the Neem 1.0 L ha-1 treatment with 8,940 kg ha-1.
The investigation evaluated the effect of fertilizers potásicos with fosfitos on the yield of grain of hard corn (Zea mays L.), in the Property "Santiago", located in the Km 26 way Babahoyo-San Juan, county of Los Ríos. A rehearsal settled down in the hybrid corn DK-7088, measuring the answer from the corn to the application of fertilizers potasic and fhosphite, to determine the dose with more effect on the production. 19 treatments were proven with Chloride of potassium, Sulfate of potassium and Nitrate of potassium, with fhosphite of Calcium, Magnesium and Potassium, more a witness without applications. The used experimental design was complete Blocks at random in three repetitions, the evaluated variables were subjected to the variancia analysis, and the test was applied from Tukey to 95% of probability. The evaluated parameters were: plant height, days to flowering, longitude and ear diameter and yield for hectare. Found increases in grain yield with three treatments, highlighting the treatment with the application of muriate of potash in conjunction with Calcium phosphide (9451,65 kg ha-1 ). The results indicate the possibility of increases of more than 49% in relation to the witness (6339 kg ha-1 ) where there was applied the treatments.
A presente investigação foi realizada com o objetivo de determinar a interação entre os diferentes níveis de fertilização e misturas de herbicidas no cultivo de arroz (Oryza sativa) na área de Babahoyo. Foi utilizada a variedade de arroz INIAP 15. Foi aplicado o delineamento de Parcelas Divididas, cujos tratamentos consistiram em níveis de fertilização, subtratamentos por mistura de herbicidas e três repetições. Para a comparação das médias, foi utilizado o teste de Tukey com significância de 5%. Para estimar os efeitos dos tratamentos e subtratamentos, os dados do índice de toxicidade foram avaliados aos 7 e 14 dias após a aplicação dos herbicidas, controle de plantas daninhas aos 15 e 30 dias após a aplicação dos herbicidas, altura da planta na colheita, número de perfilhos / m2, número de panículas, dias para o florescimento, maturidade fisiológica, comprimento da panícula, grãos por espiga, peso de 1000 grãos, rendimento de grãos e análise econômica. Os resultados mostram que a interação dos níveis de fertilizantes e misturas de herbicidas obteve efeitos positivos na produção da cultura do arroz (Oryza sativa L.), na área de Babahoyo; Aos 7 dias, a toxicidade na cultura era sem danos e aos 14 dias poucos danos foram mostrados; o melhor controle de plantas daninhas foi apresentado com as misturas de Piribenzoxim + 2,4 D amina (1,0 L + 0,7 L) aos 15 e 30 dias após a aplicação dos produtos; Características agronômicas como altura da planta, perfilhos e panículas / m2, comprimento das panículas e grãos por espiga foram influenciadas em suas médias com a aplicação de Nitrogênio (160 kg / ha) + Fósforo P2O5 (40 kg / ha) + Potássio K2O (60 kg / ha); Nos dias para a floração e maturidade fisiológica, todos os tratamentos e subtratamentos responderam da mesma forma porque foi utilizada a variedade Iniap 15; o maior peso de 1000 grãos e produtividade foi apresentado na aplicação de Nitrogênio (160 kg / ha) + Fósforo P2O5 (40 kg / ha) + Potássio K2O (60 kg / ha) e nas misturas de herbicidas aplicadas nos três subtratamentos e. o maior benefício líquido foi alcançado aplicando como fertilizantes Nitrogênio (160 kg / ha) + Fósforo P2O5 (40 kg / ha) + Potássio K2O (60 kg / ha) complementar às misturas herbicidas baseadas em Clomazone + Pyrazosulfuron Etil (1,0 L + 0,35 kg) com $ 662,02 / ha.
