Populations of Xanthomonas campestris pv. phaseoli and other Xanthomonas occur in natural form la non symptomatic weeds. Sevently seven samples of twenty one weed species from fields Infested with common blight "Tizón común" In San Juan, Higuey, Constanza of the Dominkan Republic were evaluated. The isolationswere obtained by adding 10 ml of the buffer (12.5 mM K2PO4 + 10 mM Mg SO4, ph < 7.1). The pathogenicity tests were performed on the Dark Red Kidney bean, by inoculating plants, trifoliates and seed pods. To confirm the starch hydrolisis reaction with methyl violet and methyl green, an evaluation of the production of brown dye and thin layer chromatography for the Xanthomonadin pigment was made. Of the observed results, fourteen samples and eight species of weeds of X. campestris pv. phaseoli and 23 species of weeds of atypical Xanthomonas were found. The pathogenic isolations from leaf innoculum at two weeks the yellow zone had expanded and covered a wide area around the necrotic brown center. The bean seed pods inoculated with pathogenic isolates showed typical symptoms around ten days. All the pathogenic isolates on the leaves became pathogenic on the seed pods. None of the isolates of collected weeds after harvest. In the "Constanza" area showed any symptoms on the bean leaves. The weed samples collected from the common blight Infested fields had more pathogenic of isolates X. campestris pv. phaseolithan the samples taken from the outside ends of the fields or after harvest. We found eight weed species all belonging to six botanic families which might act as sympto-matic hosts suggests that other species could contain epiphitic X. campestris pv. phaseoli.

The objective of this research was to determine the effects of substituting chicken manure for the common feed stuffs used In the first four to eight weeks of the growing period of shrimp. Economical evaluations of shrimp production was also considered. Twelve man made ponds (2.2-3.0 ha) located at Granjas Marinas, San Bernardo, S.A, San Bernardo, Choluteca, Honduras were assigned to four treatments at random and seeded with young shrimp (average weight 0.8 g) at a rate of 5/m2 on September 7, 1998. The treatments tested were: 1) (STANDARD) the normal treatment used at Granjas Marinas San Bernardo which consisted in the application of chicken manure during the first eight weeks plus added feed, 2) (FEED) feed only, 3) (4 WEEKS) chicken manure only during the first four weeks followed by feeding, 4) (8 WEEKS) chicken manure only during the first eight weeks followed by feeding. After ninety nine days ofshrimp cultivation, there was Do Increase In production using low rates of chicken manure (60 kg total solids/ha/week) during the first eight week of feeding. It was also found not to be economical to feeding for low rates of fertilization with chicken manure, especially after the first two or three weeks of cultivation. The average weight of shrimp for treatments FEED 14,4, and STANDARD 14.1, was significantly greater than that observed for 4 WEEKS 12.2, and 8 WEEKS 17-1. The average shrimp production was 7-41% greater In STANDARD and FEED treatments (%)* and 518 kg/ha respectively) compared to 4 WEEKS (476 kg/ha) and 8 WEEKS (368 kg/ha). However, there were no significant differences between treatments due to the high amount of variability caused by survival rates (P<0.01). The total costs for FEED and STANDARD were significantly greater compared to 4 and 9 WEKS. This was due to a greater feed utilization in the previous treatments. Estimated gains In FEED (L. 30851ha) and STANDARD (L. 3026/ha) were 27-58% greater than 4 and 8 WEEKS (L. 2389/ha, and 1947/ha respectively). This was due to the Increased production obtained with greater prices received for the larger shrimp obtained in FEED and STANDARD treatments. There was potential to significantly increase the estimated gains by substituting feed for fertilization with chicken manure at a higher rate of application (250 kg/ha/week) during the first four to eight weeks of cultivation.

Given the importance that yellow grain maize hybrids have for human and animal consumption, the Maize Program of the Instituto de Ciencias y Tecnologia Agricola (ICTA) initiated a project using 10 maize lines to genera te double (DC) and three way cross (TWC) hybrids which would be superior to the commercial hybrid HA-46. Most of the 10 lines had different genetic origins. Specific objectives were: a) estimate specific and general combining ability (SCA, GCA) for each of the simple crosses; and b) to predict yield for the DC and TWC hybrids. A 7x7 simple lattice design was used to evaluate 42 simple crosses and 7 checks. SCA and GCA were estimated using the Fourth Griffing's Design, and yield predictions using Jenkins Method B. Two trials were established in Cuyuta and La Maquina (40 to 150 meters above sea level). Results obtained indicated that the two null hypothesis could not discarded: 1) the variance for GCA (g 2) was considered to be equal to zcro givcn that the testers wcre previously selected; and the variance for SCA (s 2) was different from zero, possibly because some testcrs had different origins while others were derived from the same source. 2) SCA was as important as CGA in predicting the yicld of the simple crosses. Predicted yield levels for DC’s and TWC's were highcr than the predicted yield for HA-46. These results suggest that when these DC's and TWC's are formed they will be superior to HA-46 and as such fulfill the general objective set forth.

Two trials were conducted in 1990 in the zone of Azuero-Panama, to observe the response of the corn to the residual effect of sulphur (CaS04) under two application methods. In 1989, sulphur was broadcasted at arate of 0.20, 40 and 80 kg/ha, or handspiked at arate of 0.20 and 40 kg/ha. During the second cycle (1990), only 100 kg/ha of N were applied to the plots in order to observe the residual effect of the treatments. There was a lineal response for the two bypsum application methods in the first cycle, but there was no interaction among these two independent variables. The fact that one of the. highest yields wasobtained with a 20 kg/ha, doseshows us that a low dosage of this element is anough to have significant responses. The resiudal response of the sulphur application (1990) was highly significant getting yield increments ranging from 0.483 to 1.682 t/ha. The economic analysis of the two cycles (1989-1990) showed that the sulphur application was profitable with respect to the dose 0 (zero), given the low cost of the agricultural gypsum.

During the development of hybrids, non-related progenitors of opposite heterotic pattern were used. When heterotic patterns of different germplasm are not well defined, or the heterotic response among existing materials is low, it is possible to develop inter-line hybrids with some materials. The objective of this study was to determine the yield of intra and inter-population hybrids developed from lines from Pool-19 and Pool-20 (Dialelo 1); lines from Pob.32, 25 and Pool-23 (Dialelo 2); lines from Pool-24 and Pob.24 (Dialelo 3); and lines from Pob.21, Pool-23 y Pob.32 (Dialelo 4), evaluated in México, Central America and Africa. Intra and interpopulation hybrids were also evaluated in experiments involving crosses of white tropicallines to testers from Populations 21, 32, 25 and Pool-24. Interpopulation hybrids outyielded intrapopulation hybrids from 8.0 to 15.6%. In the line x tester experiments, the interpopulation hybrids also outyielded intrapopulation hybrids. In the four dialells, the best intrapopulation hybrids yielded from 92.2 to 118.6% in relation to the best control. This indicates the possibility to obtain high yielding intrapopulation hybrids. Similar results were obtained from the line x tester experiments.

The purposes for estimating the genetic parameters were two fold: 1: the determination of geme action, 2: to supply the basic information for determining wich methodology of genetic improvement is to use. The objectives of this investigation are: to estimate heritability, genetic variability and general combining ability of the full sib families with pedigree. Two hundred and twenty four full sib families were evaluated in three localities of the humid tropics in Mexico. The variables studied were: tasseling and silking height, ear height, number of ears per 100 plants and yield. Significant differences were found at 0.01 probability for the source of variation of localities, replications within groups and localities, families within groups and in the interaction of localities by families/group. The coefficient of variation for days to tasseling and female flowering were 1.48 and 1.53 percent, respectively; for plant height and ear height was 5.27 and 8.54 percent, respectively and for number of ears per 100 plants and yield were 5.97 and 10.38 percent, respectively. The heritability values were: tasseling 0.734, silking 0.752, plant height 0.759, ear height 0.815, number of ears per 100 plants 0.434 and yield 0.583 and lastly, the families showed a good general combining ability.
Algunas reflexiones sobre la producción de granos básicos en Centroamérica
Authors: Christophe Guy 
Published: October 2018

The situation of the staple grain production in the Central American area is full of contradictions. Although there has been an increment in the food production, apparently sufficient, compared with the population growth, the yields have remained stagnant in the last decade. In the whole region, the real prices at farm level have dropped dramatically during these years of economic crisis. The state policies of organizing a regional market for basic food faces the large prevalent differences in prices and costs of grains among the Central American countries. According to a comparative analysis, these differences are stemmed in the prices of chemicals input s and mechanization costs at the farm level, which jeopardize the international region' s competitiveness and then may hurt those countries with relatively higher technified production within the region. In fact, the last available data confirms that, in economic terms, the technology for basic food production is not as effective as traditional farming. Finally, the massive food aid received by the isthmus, mainly wheat, has caused a change in the relative prices of staples food and leads in the urban, consumer to modify his feeding habit.

The soil, nutrient and water conservation is the main problem faced by farmers and investigators under the corn crop-based systems in Central America and Mexico. Several farmers from Honduras have come up with an efficient technology for the corn planted on hills, in which the bean manure is planted in rotation with corn during the dry season. The results from the conducted survey, at the Departamento de Atlantida in Honduras, indicate that 66 % of the farmers grow most of the corn through the protective mat produced by the beans during the rainy season. Among the advantages of this rotation, compared to the traditional burned and cleared land, are the higher yields with les ser dependency of external imputs, shorter rest periods, lower land preparation costs, less soil erosion and lower risk of drought damages. The problems linked to the diffusion ofthe system include the risk ofland slides and a higher plague's incidence (rats) on the corn planted through the manure mat. Usually, the amount of land available in the regionalland markets is the determining factor on the diffusion of this system, and not the size of the farm nor the form of land tenancy.

The objective was to develop a stable and non-compliance coated solid–lipid nanoparticles (coated SLN) using polymer (Eudragit L100) and lipoid (glycerol monostearate: soya lecithin) for partial dose reduction of isradipine [ISR; 2.5 mg by combination of bioenhancing agent (rutin; Ru) in equivalent ratio]. The physicochemical characterizations were performed by FT-IR and DSC of elected model drug (ISR), drug mixer with Ru/polymer and coated SLN with Ru (ONbp); the resulted distinctive peaks demonstrated that no chemical interaction and incompatibility found between them. The plasma samples of formulation (ONbp) were analyzed by liquid chromatography (HPLC) using UV-spectrometer. Data were integrated and analyzed with the help of a computer-designed program “Kinetica Software” (Thermo Scientific Kinetica, PK/PD Analysis, version 5.0, Philadelphia, PA). The pharmacokinetic study showed 3.2- to 4.7-folds enhancement in oral bioavailability of coated SLN of ISR with Ru (ONbp) when compared to a coated formulation of ISR without Ru (ONps) and conventional drug suspension. In vivo studies were revealed significantly at greater extent in (drug stability and solubility) oral absorption, which has shown potential entrapment efficiency (97.85% ± 1.02%) to improve biological activity against hypertension. Hence, nano-system of ISR against hypertension is achieved with consequent dose reduction with enhanced systemic bioavailability.
