In order to avoid dependence on improved seeds, at the Technological Institute of Comitancillo, a genetic improvement program has been started through the selection of white grain populations. The production of white grain sorghum represents a great opportunity due to its higher protein content and being a stimulus or condition for a better harvest price compared to red grain sorghum. The objective of this work was to select and characterize lines in S6 of populations of white sorghum, for the creation of open-pollinated varieties or progenitors of hybrids under local conditions. In the spring-summer 2018 agricultural cycle, a total of 114 lines generated in a previous year were evaluated. 26 % of the germplasm presented a grain yield of 3.82 ton/ha, the panicle length ranged from 14.8 to 25 cm, the panicle diameter was 2 to 8.4 cm, in weight of 1000 grains 22.6 to 40 g, grains per panicle from 855 to 2400. It is recommended to increase seeds of the outstanding lines, to carry out yield tests and establish validation plots with regional producers.","PeriodicalId":360677,"journal":{"name":"Journal of Agricultural Sciences Research (2764-0973)","volume":"307 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132703360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Preferably, planting is recommended in well-prepared, fertile, deep and loose soils, to allow the development of the root system. This work aimed to evaluate the response of a cultivar (BRS Energy) and a lineage (CNPA 2009-7) of castor bean to increasing doses of N and P in the soil in two locations in the northeastern semi-arid region: rural areas of the municipalities of Apodi (RN ) and Barbalha (CE). The doses of N tested were: 0, 50, 100, 150 and 200 kg/ ha and those of P, 0, 50, 100, 150 and 200 kg/ha. The experiments were distributed in randomized blocks with four replications, making a total of 40 plots. The cv. BRS Energy showed a greater absorption of nitrogen in the soil and, consequently, synthesized more crude protein than the CNPA 2009-7 genotype. In addition, it showed greater efficiency in calcium absorption. On the other hand, the genotype proved to be more efficient in the absorption of phosphorus and magnesium. The cultivar naturally showed a higher castor bean production, as evidenced by the significantly higher variables related to the production of fruits and seeds. It also had a higher oil content in relation to the genotype. In both locations, the content of N and, consequently, of proteins, in castor bean leaves increased as a function of the dose of nitrogen fertilizer.","PeriodicalId":360677,"journal":{"name":"Journal of Agricultural Sciences Research (2764-0973)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128099524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mexico is in tenth place worldwide and this product is one of the most exported vegetables, mainly to the United States of America. In 2020, the Comarca Lagunera allocated an area of 984 ha under shade mesh with a production of 138,036 tons. Due to the economic and social importance in the region, the objective was to determine the productivity indicators of water, soil, labor and capital, which will support the producer to make better decisions. To carry out the study, five production units under shade mesh that occupied 50 % of the total planted area were selected through systematic sampling and the necessary information was obtained through a survey, finding that the average value of the indicators was 11.9 kg. tomato per square meter; 54.3 kg of tomato per cubic meter of water, and 61.9 and 99.7 pesos the net income obtained per square meter of surface and cubic meter of water, respectively. The highest values were registered by the largest production units, concluding that this behavior is due to the greater economy of scale and greater care with which the crop is managed.","PeriodicalId":360677,"journal":{"name":"Journal of Agricultural Sciences Research (2764-0973)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125779655","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
