The aim of this investigation was to identify and select advanced lines with a wide genetic base, derived from crosses between Saladette tomatoes and native populations to generate free pollination varieties and potential parents of Saladette tomato hybrids. The hypothesis was that crosses between native populations and Saladette commercial hybrids generate outstanding offspring. The 103 genotypes evaluated included 10 native parents, three parents derived from commercial hybrids, one commercial hybrid control (“El Cid”) and 89 S4 advanced lines. The evaluation was carried out in a greenhouse and hydroponics during the 2020 spring-summer cycle, using a randomized complete block experimental design with three replications and four plants per replication. The total weight and number of fruits were recorded based on the sum of the two cuts performed. The days to flowering of the first cluster, average fruit weight, and total soluble solids were also determined. Analyses of variance were carried out for each variable, as well as orthogonal contrasts and correlations between different combinations of the materials of interest. The comparison of means was carried out using Tukey’s test (p ≤ 0.05). Nine advanced lines with similar or greater characteristics to the control were identified and are recommended to be recombined genetically in a diallelic cross scheme to identify new outstanding offspring. The advanced line 2051 (LOR85 X C) was identified, with a similar yield to that reported for the control, which can be used as an open pollination variety since it has similar characteristics to the control “El Cid”, but with native tomato genes.","PeriodicalId":50836,"journal":{"name":"Agrociencia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135719655","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results showed that the yield of B. bassiana conidia produced with rice was 15 higher than that produced with amaranth stubble.

Such is the case with the systems proposed in the Nueva Colombia (New Colombia) farm, located in the Pondores area of the Fonseca municipality in La Guajira, Colombia. In order to answer the question “Are the production systems of the Nueva Colombia farm sustainable?”, we carried out a qualitative agroecological assessment of five systems used (maize [Zea mays L.], cassava [Manihot esculenta Crantz], plantain [Musa x paradisiaca L. var. Hartón], cattle ranching, and poultry farming). Producers, technical consultants, and researchers participated in the assessment, with the goal of establishing a viability baseline and criteria to determine the convenience of allocating resources for the continuity of the systems. The results show that the Nueva Colombia farm is located in a very dry tropical forest life zone. The assessment shows moderate sustainability for plantain and cassava crops and weak sustainability for maize. As for the animal production systems, it was found that cattle ranching is not a sustainable system and that, therefore, its operation is not viable, while poultry farming is moderately sustainable. We concluded that it is not advisable to continue cattle production, and that the resources should be reallocated towards improving the poultry farming system. The agricultural systems require the implementation of practices that increase the specific and spatial diversity of crops, as well as their stress tolerance and the proportion of organic matter in soil.","PeriodicalId":50836,"journal":{"name":"Agrociencia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135865001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this sense, it was proposed that the number of ASF publications related to food security and natural resource conservation increase on an annual basis. The objective of the present study was to perform a quantitative analysis of agroforestry research published between 1990 and 2022 from Web of Science in Mexico with a bibliometric approach. There were 204 publications related to agroforestry systems, recording an increase of 86 % in the last decade. Among the scientific journals analyzed, Agroforestry Systems and Journal of Ethnobiology and Ethnomedicine registered the highest number of publications and citations. The most frequent terms mentioned in publications over 32 years were the relationship between the effects of ASF on crops, traditional management, local knowledge, and the conservation of natural resources. The Universidad Nacional Autónoma de México (UNAM) is the institution with the highest number of research works on the subject, mainly by scientists Alejandro Casas Fernandez and Isabel Moreno Calles, both individually and collaboratively.

This results in economic losses and environmental pollution. A fertigation system designed at the Colegio de Postgraduados (COLPOS) Campus Veracruz was established to determine the uniformity and stability of fertilizer distribution in the sugarcane crop. This study was carried out in a sugarcane plot with a farmer participant. Three levels of valve openings at the injector inlet (1/3, 2/3, and 3/3) were tested to determine the homogeneity of fertigation at the outlet of the gates and the stability of the system over time. Samples of water-fertilizer mixture were taken at the outlet of the gates. They were analyzed in the laboratory with a UV-visible spectrophotometer at 202 nm for nitrogen. It was found that the 1/3 and 3/3 valve position openings caused instability in the system. For the 2/3 opening with p = 0.359, no statistical difference (α= 0.05) was found during the time of emptying the container of the water-fertilizer mixture. Therefore, the fertigation system proved to be stable with a valve opening close to 2/3. Using the valve openings, the flow rate of water-fertilizer entering the system is uniformly mixed at the outlets of the multi-gate pipeline that pours into the crop furrows (p = 0.474 and α = 0.05).

This study evaluated the effect of food and water supplementation by capture-mark-recapture using camera traps at the UMA San Huberto, Sonora, Mexico. During the winter of 2015-2016, male mule deer counts and detection histories were collected at 62 photo-trapping stations spread across four supplementation treatments: 1) water and food, 2) water, 3) food, and 4) no supplementation. In addition, to assess the impact of natural vegetation on trough and feeder utilization on the ranch, the Normalized Difference Vegetation Index was calculated using Landsat 8 satellite images. A log-Poisson regression model for deer counts per photo-trapping station found that food supplementation increased mule deer numbers by 42 % when compared to stations without food supplementation. Vegetation biomass had no effect on the frequency of use of feeders and waterers in any of the treatments. According to the multistate model for detection histories, male mule deer at waterers receiving food-only supplementation are more likely to remain in that treatment than to move to either of the other two treatments (water and feed or water). This finding suggests that food-only supplementation is more effective in retaining male mule deer.","PeriodicalId":50836,"journal":{"name":"Agrociencia","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2023-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77823155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
