The purpose of the study was to evaluate the performance of six quinoa cultivars (Chenopodium quinoa Will) under agroecological conditions in Vilcabamba - Apurímac, to determine which cultivar presents the best performance. The experimental design was adopted where the variables were manipulated six varieties of quinoa, which were distributed in a completely randomized block design arrangement (DBCA) having three repetitions, with eighteen experimental units. The results show that the six quinoa varieties present a significant difference at 95% reliability, since the value of Pr(>F) is less than 0.05. which is ratified with the Tukey analysis at 95% reliability, is such that the grain weight per panicle of six quinoa cultivars (g), by blocks (B1, B2, B3) had the average and the variance; the variety with the lowest grain weight per panicle is Pasankalla with 8.37 gr followed by INIA ...

The objective of the research was to evaluate the response of the localized application of earthworm humus in the potato crop of the Canchán INIA variety. The study was carried out in the Grau province of the Apurimac department. The study variables were the vegetative growth represented by the indicators: percentage of emergence, percentage of lateral shoots, plant height between periods and the number of stems between 30, 60 and 90 days after sowing. With a completely randomized block design. The results show that there are significant differences (Sig.<0.05) between the treatments, being the localized application of earthworm humus at 0.5 Kg/plant the highest averages of emergence and lateral shoots of 95%. The results in the yield parameters are reported greater than 0.5 Kg/plant, among which the tuber yield of 32.1525 t/ha stands out, tuber weight per plant of 868.1375 g/plant, ...

The objective of the research was to evaluate the effect of earthworm humus, bovinase and whosease in the vegetative phase and yield of the onion (Allium cepa L.) red variety Arequipa. The study was carried out in the district of Curpahuasi, province of Grau, department of Apurímac. The study variables were plant height, number of leaves, bulb height, bulb diameter and onion crop yield. With a completely randomized block design. The results showed significant differences (Sig.<0.05) reporting a higher plant height with the application of Worm Humus with a dose of 10.8 t/ha, while the highest number of leaves was found with the application of Bovinase at a dose of 20 t/ha. The production yield was found with the Earthworm Humus (9.8 t/ha) higher compared to the other biofertilizers, being non-significant (Sig. > 0.05) when compared with the other treatments, no significant differen...

For decades, rock structures were designed based on empirical methods, based on professional experience, support systems tended to be overestimated with the consequent increase in costs, without giving interest to the intrinsic resistance of the rock and applied to Similar cases. The development of the study of Rock Mechanics has reached high levels that have contributed to solving complex problems in rock masses of varied geomechanical conditions, allowing the construction of extensive works in low resistance massifs such as long underground tunnels, underground constructions, food pantries. , underground shelters among others, to take advantage of underground space, especially in countries with high population density. The objective in the Road Tunnels is to seek adequate support for their stability, through a probabilistic study. In the excavation of the Karkatera tunnels, the use of ...

The objective of the research was to describe the use of pollutants in the cultivation of Maize Zea mays L. The study was carried out in the district of Curahuasi, Abancay Apurímac Province, Peru. The type of study was quantitative with an explanatory level. The Concacha-Curahuasi transect was evaluated, simple random probabilistic sampling was applied in a total population of 345 families from the communities and producer associations, the sample was 20% of farmers. The field work was carried out in October 2018. The results achieved showed that 92.16% of farmers use insecticides indiscriminately to control the aforementioned pests, 94.1% consider that corn, water and soil are contaminated. They do not do any treatment for the final disposal of empty containers. In conclusion, in the production of choclero corn, in Curahuasi, they use agrochemicals that contaminate the crops and the en...
