Agroproductive Behavior of Four Onion Varieties (Allium cepa) in Suburban Arid Lands in Camalote, Camaguey, Cuba

Four onion varieties of onion (Allium cepa) were studied in order to evaluate their behavior in the edaphoclimatic conditions of Ignacio Agramonte CCS, Camalote Agricultural Company, municipality of Nuevitas, Camaguey, Cuba. A randomized block design with four treatments and three replicas was used on alluvial soil, between November 2013 and March 2014. For evaluation of the phenological behavior and the crop´s yield indicators, plant height, number of leaves, bulb diameter, bulb formation, and yields (t/ha), were evaluated. One-way variance analysis was made to the data collected. The Hybrid Yellow Granex had the best bulb formation (90%); Texas Early Granex 502 had the highest yield (17 t/ha)

Comportamiento agroproductivo de cuatro variedades de Cebolla (Allium cepa, L) en zonas áridas suburbanas de Camalote, Camagüey, Cuba

Con el propósito de evaluar el comportamiento de la cebolla (A. cepa) fueron estudiadas cuatro variedades con el propósito en las condiciones edafoclimáticas de la CCS Ignacio Agramonte, perteneciente a la Empresa Agropecuaria de Camalote, municipio de Nuevitas. Se utilizó un diseño de bloques al azar con cuatro tratamientos y tres réplicas sobre un suelo aluvial durante el periodo comprendido entre noviembre 2013 a marzo del 2014. Para la evaluación del comportamiento fenológico y los indicadores de rendimiento del cultivo se evaluaron la altura de la planta, número de hojas, diámetro del bulbo, cierre del bulbo y el rendimiento en t/ha para ello se utilizó un diseño de bloques al azar con cuatro tratamientos y tres réplicas. Los datos obtenidos fueron sometidos a un análisis de varianza de clasificación simple. La variedad Yellow Granex Híbrida presento el mejor cierre del bulbo (90%) y la variedad Texas Early Grano 502 el mejor rendimiento (17 t/ha)

Adoption of Agricultural Conservation Practices in the Ignacio Agramonte Cooperative of Credits and Services (CCS), Nuevitas, Camaguey

The adoption of sustainable technologies, like Agriculture Conservation Practices in drought-stricken suburban areas is a must for land sustainable management. In order to contribute with the inclusion of this technology at the Ignacio Agramonte CCS, in El Carmen, municipality of Nuevitas, Camaguey, Agricultural Extension tools were used, like systemic diagnostic and participatory orientation. The SWOT matrix was created after three workshops, where agricultural conservation practices were identified for adoption, based on actual conditions at the CCS. As a result, five key problems were identified: lack of water for irrigation, saline waters, saline soils, use of inappropriate management technologies, deforestation and poor training in agriculture. The most critical impact found in the matrix was in Weaknesses - Threats (81.3%). Furthermore, local farmers, inhabitants and public officials agreed on the use of agricultural extension tools to provide positive elements and an effective way to help increase motivation and knowledge about agricultural conservation technology, as an alternative to mitigate the degradation state of lands at the CCS

The behavior of Three Rice Varieties against Steneotarsonemus spinki Smiley in Vertientes, Camagüey

Context: In Cuba, the proliferation and spread of rice acarid Steneotarsonemus spinki Smiley, is one of the main hindrances to rice productivity growth. Although integrated management is performed in the municipality of Vertientes, the acarid causes yield losses accounting for 15-20%. Aim: To determine the incidence of acarid S.spinki and the agro-productive behavior of rice varieties IA Cuba- 31, J-104, and Prosequisa -4. Methods: Two evaluations were made to determine the presence of the pest in the crop. Besides, farming and industrial parameters were measured. The data collected were analyzed through simple analysis of variance, using SPSS, version 11.5.1, for Windows. Results: The results show that variety Prosequisa 4 withstood the lowest incidence of the acarid, being the crop variety with the highest farming and industrial yields, followed by the IA Cuba 31. Conclusions: This study recommends the following varieties for inclusion in the varietal policy for large and small-scale rice growers: Prosequisa -4 and IA Cuba 31

Uso de fertilización orgánica basada en orina humana en el cultivo del maíz (Zea mays L.).

El presente trabajo estudia el efecto de la orina humana en el desarrollo y rendimientos del cultivo del maíz, variedad Matuba. El experimento se realizó en el Instituto Agrario de la Ciudad de Mocuba, Mozambique, usando un diseño de Bloques al azar con tres tratamientos (T0-sin fertilización, T1-Fertilizado con orina humana y T2-Fertilización química), y tres repeticiones, sobre un suelo arcilloso. Los resultados fueron sometidos a análisis de varianza del paquete Statistix 10.0 y las medias comparadas por la dócima de Tukey para una probabilidad de 5%. Las variables evaluadas fueron: altura de la planta (HP), diámetro de la mazorca sin paja (DM), largo de la mazorca (CM), peso de la mazorca (Pe) y rendimiento. Respecto a los tratamientos utilizados, los resultados del empleo de fertilizante orgánico a base de la orina humana resultó significativamente superior en los parámetros referentes la altura de la planta (HP) y diámetro de la mazorca (DM), sin diferencia significativa a respeto del tratamiento con químico (T2) en los parámetros largo de la mazorca (CM), peso de la mazorca (Pe) y rendimiento (R), que alcanzó en el caso de la orina humana 4.80 t/ha. Desde el punto de vista experimental, el presente estudio evidenció resultados promisorios acerca de la utilización de orina humana en la fertilización del maíz (Zea mays, L), indicando la posibilidad de su uso en la agricultura familiar reduciendo o sustituyendo el consumo de fertilizantes químicos.Use of organic fertilizers based on human urine in maize (Zea mays L.).ABSTRACTTo test the effect of human urine on the yield of maize variety 'Matuba', conducted at the Institute of Agrarian of City Mocuba an essay using the randomized complete block design with three treatments (no fertilization T0, T1 fertilization with human urine and T2 chemical fertilization), and three replications in clay soil The data were interpreted by an analysis of variance package Statistix 10.0, the means were compared by Tukey test at 5% probability. The variables evaluated were: plant height (PH), ear diameter (DM), ear length (CS) ear weight g (PE) and yield (t/ha). Respect of the treatments tested, the application of human urine resulted in significantly higher parameters for plant height (PH) and diameter of the ear (DM), and no significant difference regarding the treatment with chemical fertilizer (T2) parameters ear length (CS), ear weight (PE) and ear (R), which reached in the case of human urine 4.80 t/ha. From the experimental point of view this study showed promising results on the use of human urine fertilization of corn (Zea mays L.) , indicating a potential application of human urine in agriculture in order to reduce consumption or even in some cases replace use of chemical fertilizers

Effect of Five Biostimulants on Sugar Cane Seedling Strengthening and Resistance to Transplantation

Context: The stress undergone by sugar cane during the seedling strengthening stage may be caused by various reasons, such as pest infestation, nutritional deficiencies, and mechanical damages due to manipulation that leads to the loss of genetic material. Objective: To evaluate the effect of five biostimulants on sugar cane seedling strengthening and resistance to transplantation. Methods: A completely randomized experimental design with six treatments (absolute control and samples with the application of azotobacter, phosphorine, improved natural liquid humus, and mineral-fortified liquid humus (BoCalZn)), and four repetitions, was used. The seedlings were placed on a 60-well tray filled with a mix of soil and filter cake. Seven foliar applications were made between days 7 and 56 following transplantation. Plant height and thickness, foliar area, root length, number of active roots, and fresh and dry weights were evaluated 50 days after. For evaluation of resistance to transplantation, the strengthened seedlings were placed in the field, and 45 days later, their survival percentage was determined. Results: The positive effects of the biostimulants applied were observed on the morphophysiological indicators. Conclusions: The application of biostimulants showed the positive effect on the morphophysiological indicators evaluated. The best transplantation resistance of the mineral-fortified liquid humus (BoCalZn) was observed in field conditions
