The Effect of Green Tonic Fertilizer and Pearl NPK Fertilizer on the Growth of Forestero Cocoa Plant Seeds (Theobroma cacao L) The aim of this study was to determine the effect of Green Tonic, NPK Mutiara and the extraction of Green Tonic and NPK Mutiara on cocoa seedling growth. This research was carried out at Gunung Panjang Samarinda Seberang East Borneo. with a time of ± 3 months, starting from April to July 2016. The design of the study used factorial randomized block design (RCBD) 4 x 4 with a number of replications 3 times, with factorial analysis. The treatment consists of 2 factors. The first factor is the administration of POC Green Tonic consisting of 4 levels, namely: p0: Without treatment, p1: 2 ml / 1 Liter of Green Tonic Concentration, p2: 3 ml / 1 Liter of Water Tonic Concentration, p3: 4 ml Green Tonic Concentration / 1 Liter of Water, The second factor was the administration of NPK Mutiara consisting of 4 levels, namely: v0: Without treatment, v1: Giving NPK Mutiara Fertilizer 50 grams / polybag, v2: Giving NPK Mutiara Fertilizer 100 grams / polybag, v3: Giving NPK Fertilizer Pearl 150 grams / polybag. From the analysis of variance showed that the effect of giving green tonic liquid organic fertilizer (P) was the best on the parameters of stem diameter of 30 DAP and 60 DAP of cocoa plants achieved by the treatment of p3 (4 ml / 1 Liter of Water Green Tonic Concentration), NPK Mutiara fertilizer (V) the best in the parameters of plant height 30 DAP, 60 DAP and 90 DAP, stem diameter 30 DAP and 90 DAP, number of leaf 60 DAP, leaf area 30 DAP cocoa plants achieved by v3 (Giving NPK Pearl Fertilizer 150 gram / polybag) while for stem diameter 60 DAP, number of leaves 30 DAP achieved by v1 (Giving NPK Mutiara Fertilizer 50 g / polybag), for the number of leaves 90 DAP, the area of Leaves 60 DAP and 90 DAP achieved by v2 (Giving NPK Pearl Fertilizer 100 g / polybag), The best interaction of POC green tonic and NPK pearl (PV) fertilizer on stem diameter parameters 30 DAP and 60 DAP, number of leaves of 90 DAP, leaf area of 60 DAP and 90 DAP was achieved by p3v2 (4 ml / 1 Liter Water + Green Tonic Concentration Pearl NPK fertilizer 100 grams / polybag. The difference for 30 HST leaf area is achieved by p1v3 (2 Ton / 1 Liter Water + Green Tonic Concentration + 150 gram Pearl NPK Fertilizer / polybag).

Introduction: This research was determined the growth response of cocoa (Theobroma cacao L.) in N-fertilizer and sugarcane bagasse compost. Materials and Methods: This research was conducted at agricultural area of ​​Sejati Street, Sari Rejo Village, Medan Polonia Sub-District, Medan. This research was conducted from August until December 2015. This research used therandomized block design in factorial. The first factor was N-fertilizer with 4 rates, 0 g.polybag-1 (P0), 2 g.polybag-1 (P1), 4 g.polybag-1 (P2),and 6 g.polybag-1 (P3). The second factor was the provision of sugarcane bagasse compost with 4 rates, 0 g.polybag-1 (K0), 2 g.polybag-1 (K1), 4 g.polybag-1 (K2) and 6 g.polybag-1 (K3). The observed data were analyzed by the F-test, and continued with the DMRT at level of 5%. Results: Composting bagase significantly affected the leaf area of cocoa seedling at 2 and 4 weeks after planting. The application of N-fertilizer had significant affected the number of leaves for cocoa seedling. The interaction of P2K2 (6 g.polybag-1 N and 4 g.polybag-1 of bagasse compost) showed the highest fresh- and dry-weight of cocoa seedling compared to other interactions, although the effect was not significant.

Objetivo: Establecer una línea base como fundamento para la intervención e inducción de innovaciones a través de escuelas de campo y planes de negocios. Diseño/metodología/aproximación: El estudio se desarrolló en San José del Carmen, San Cristóbal de Las Casas, Chiapas, México. Se elaboró una encuesta como instrumento para recabar en campo información de familias de la localidad con la finalidad de conocer su situación actual. La localidad de trabajo se eligió utilizando como criterio las poblaciones que se encuentran dentro de Cruzada Nacional contra el hambre y en la clasificación de la pobreza extrema Resultados: La localidad de San José del Carmen es considerada como de alta marginación, la población es bilingüe, su principal lengua es el Tzotzil, el nivel de estudios promedio es hasta el tercer año de primaria, las principales actividades productivas son la siembra de maíz (Zea mays L.), frijol (Phaseolus vulgaris L.), papa (Solanum tuberosum L.) y haba (Vicia faba L.) que son utilizadas principalmente para autoconsumo.  No cuentan con agua potable ya que su sistema es a través de la recaudación de agua de lluvia o a través de un jagüey. Sus principales actividades económicas son la albañilería por parte de los hombres, y venta de productos, tales como el pozol (bebida energética a base de maíz y cacao (Theobroma cacao L.), tostadas y algunos vegetales por parte de las mujeres. Las tostadas son producidas en forma artesanal con un proceso de doble nixtamalización y vendida en bolsas de 20 tostadas cada una, a un costo de MX$10.00 en los mercados de San Cristóbal de las Casas, una a dos veces por semana alrededor de 40 bolsas por día de venta. Limitaciones del estudio/implicaciones: La afiliación zapatista de alguno de los pobladores y el hecho de que algunos habitantes no hablen español, fueron factores que limitaron desarrollar al 100% el estudio; sin embargo, se considera que se tienen los elementos necesarios para establecer la línea base de la situación de San José del Carmen. Conclusiones: El diagnóstico servirá como una herramienta para establecer una intervención a través de innovaciones y planes de negocios en la comunidad de estudio. Los pobladores cuentan con herramientas necesarias para obtener nuevos conocimientos que ayuden a un desarrollo de su producción. El idioma no deberá de ser una limitante para ello.

Theobroma Cacao L

A total of 60 farmers' cacao accessions (Theobroma cacao L.) from Nicaragua were investigated using microsatellite markers to reveal their genetic composition and to identify potentially resistant genotypes against the black pod disease caused by Phytophthora palmivora. These accessions were compared with 21 breeders' accessions maintained locally, two Criollo accessions from Costa Rica and two accessions from Ecuador. The analyses showed a low level of differentiation among groups of farmers' accessions (FST = 0.06) and that six Nicaraguan accessions were genetically closely related to the two Criollo accessions used as a reference. In addition, seven distinct genotypes were found to have allelic composition that may indicate linkage to resistance alleles, thus being potential parental lines in future breeding programmes.
