The technique of magnetizing irrigation water has been successfully adopted for producing seedlings of different varieties; however, in addition to the agronomic benefits, analyzing the economic viability is an important indicator affecting the producer’s decision in acquiring this technology. This study aimed to evaluate the effect of magnetic treatment of irrigation water on the growth and development of tomato seedlings, and its economic viability. Experiments I, II and III were treated with quality water (magnetized and non-magnetized) and different substrates. The application of magnetically treated water in the three experiments did not reduce any variables. Furthermore, magnetic treatment of irrigation water proved to be advantageous because it improved the final emergence percentage by 32.19% and 19.28% in experiments II and III, respectively. The growth of tomato seedlings was verified by the 53.97% increase in shoot dry matter in experiment II and by 29.77% increase in shoot fresh matter in experiment III. The seedlings that received magnetically treated water observed 14.61% increase in the speed of germination index in experiment I. Studying the economic viability revealed that using magnetizer to produce tomato seedlings was financially viable, as it reduced the discounted payback from 4.18 to 1.87 years and increased the accumulated net present value of 5 years from US$ 1,814.00 to US$ 14,593.00.

Beekeeping in Argentina has grown in recent times and in the north of the country it has taken on great importance, since it became a main activity for most of the beekeepers who commercialize honey, pollen, propolis and other products of the hive. In the province of Jujuy there are two large productive poles located in the Yungas and Valles regions, with great climatic differences, in addition to a great plant diversity, which makes the honeys increase their added value, since they have organoleptic characteristics of commercial interest. Producers currently register an average of 25 hives in each apiary, but about 20% of them are lost every year. This work addresses the influence of environmental factors, the sanitary management of hives against Varroa spp. and Nosema spp. as well as the yield in honey in four years of study. This made it possible to know the health status of each apiary, as well as the environmental influence on the prevalence of pathogens and parasites in the colonies and the effect on honey production.

The cultivation of hard yellow corn (MAD) is the main activity and source of economic income for producers in the Pativilca valley. The research was carried out with the aim of determining the economic sustainability of MAD production in the Pativilca valley, Lima, Peru. Surveys with structured questions were applied to 73 MAD production units in three irrigation commissions in the Pativilca valley (Vinto, Potao and Araya). The data were processed using multicriteria analysis techniques. To find the values of the sub-indicators, scales with correlatively ordered values were established, which admit a starting point 1 and a final point 5, considering 1 as the least sustainable and 5 the maximum value. Three indicators and seven sub-indicators were identified that affect the economic dynamics of the producers under study. At the level of the three study areas, an Economic Indicator (EI) was found whose value 3 is equal to the minimum sustainability threshold, which is why it qualifies as weak sustainability according to the methodological proposal used. At the level of the irrigation commissions, Potao was sustainable with the highest EI equal to 3.55; while, the irrigation commissions of Araya Grande and Vinto with EI of 2.70 and 2.74 respectively, resulted in a low level of sustainability due to the value below the minimum threshold of sustainability established and qualify in the range of critical sustainability.

The objective was to characterize socioeconomically and environmentally the farms producing native cocoa ( Theobroma cacao L.) in the province of Bagua. It was carried out in 5 districts of the province of Bagua: La Peca, Copallín, El Parco, Imaza and Aramango. A population of 234 farms was considered and an unrestricted sample of 70 farms was calculated; A survey was structured with questions about socioeconomic and environmental aspects of the producer and the farm. 51 qualitative and quantitative variables were obtained, being studied by Multiple Correspondence Factor Analysis (AFCM); likewise, a conglomerate analysis was performed to group according to the similarity of the most discriminating variables. As results, the predominant profile of the producers was male with primary education and between 40 and 60 years old; all farms had basic services, but with limitations. Farms smaller than 5 ha predominated and with production from 400 to more than 1000 kg. ha –1 in shaded crops with planting distances of 3 x 3; in the farms there was pest control and the cultivated soil has vegetal cover and there was presence of forest species. The cluster analysis allowed us to establish three groups of farms with similarities to each other, but with differences between the districts. Socioeconomically, the producers were predominantly male with primary education between 40 and 60 years old who own small farms and live from self-consumption; they also have basic services and access roads but with limitations. Environmentally, in general, the soils of the farms did not present erosion and had a slight slope; they managed vegetation cover, and the farms presented forest species that express that there is conservation and are related to sustainability.
