 Quinoa has been gaining attention because of its nutritional quality, low cholesterol and lack of gluten; in Brazil, the cultivation efforts in the different regions are mainly related to breeding. This study aimed to determine the genetic parameters and evaluate the productivity of the different genotypes of quinoa for detecting genotypes amenable to selection. The experiment was conducted in crop years 2010/11 and 2011/12 in environment 1 and environment 2, respectively. In environment 1, the evaluation of 61 genotypes was performed, and in environment 2, 31 genotypes were evaluated. The experimental design was a randomized block with two replications; each plot measured 2.0 x 5.0 m (10 m²) and consisted of four rows spaced at 0.45 m. Data collected on the productivity, plant height at maturation and growth cycle were analyzed using an analysis of variance, average tests and estimates of the genetic parameters. The genotypes N24 and N08 were the only genotypes more productive than the other 46 genotypes, with values of productivity of 1446.23 and 1428.93 kg ha-1 and with a growth cycle of 117 and 111 days, respectively. The heritability values determined demonstrate the possibility of genetic gain using joint selection that involves two environments.

Seeds from two locally adapted cotton cultivars, Eva and Zeta-2, were irradiated by 300 Gy γ-irradiation in order to create useful variability for earliness within each cultivar, and then to select for desirable recombinations. Selection for earliness was applied in the M2 generation and the earliest 2% of the mutants were selfed for further evaluation. After eliminating the undesirable phenotypes, the remaining material was sown in progeny rows as the M3 generation. Selection for earliness based upon morphological and physiological characteristics resulted in 5 early mutants from cv. Eva and 3 early mutants from cv. Zeta-2. These lines were further evaluated the following year for earliness, yield, fibre, and seed quality in 3 locations across the Greek cotton belt, using a randomised complete block experimental design with 4 replications. Among the 5 early mutants of cv. Eva, only one was consistently early at all 3 locations, whereas the other 4 mutants showed significant differences in the first growth stages. From the 3 early mutants of cv. Zeta-2, one was consistently early at all 3 locations. Plant height, lint yield, length, micronaire, strength, etc., as well as oil %, protein %, and gossypol %, were not significantly different from the untreated checks.

The research was carried out on the Property “El Cartan” that is located in Km 4 way at Puebloviejo-Ventanas, county of Los Ríos. A test was conducted on the hybrid corn DK-1040. This test measures the response of the larvae of insects Spodoptera frugiperda and Elasmopalpus lignosellus to the application of dose of biological and organic insecticides. Also, the most appropriate dose in products was determined with an economic analysis. The experimental design used was random complete blocks with seven treatments and three replicates. The variables evaluated are: percentage of larvae control, number of larvae per plant, corn damage, and yield for hectare. The evaluated variables were subjected to the analysis of variance, and Tukey test was applied to 95 % probability. The analyzed results were determined to apply Neem (Azadirachtina indica) in dose of 1,0 L ha -1 . It diminishes the populations of S. frugiperda and E. lignosellus in relationship to the other active matters applied in the test. Higher doses lead to migration of pests to nearby hosts. The highest yield per hectare was found in the Neem 1.0 L ha-1 treatment with 8,940 kg ha-1.

The research objective is to find out genetic variation, estimated heritability value and the expected genetic gain of Samama [Anthocephalus macrophyllus (Roxb.) Havil.] on variation in  stem diameter and plant height as superior seed producers. The research was conducted in Uraur Village, West Seram Regency, Maluku Province. The trials consisted of 80 families. All of the trials were laid out in randomized complete block designs (RCBD), 4-trees plots with 4 replications (blocks) at spacing of 5m×2m. Data collection was carried out for 2 months (February to March 2020) and was focused on observing growth variations and genetic parameters in the progeny trial block at 4 years of age including plant height and diameter at breast height. The results of this study indicate that there are variations in growth, where the Anova test results show very significant differences in the plant height parameters namely Family (F = 3.417 p 0.01), Block (F = 437.465 p 0.01) and Family and Block Interactions (F = 3.351 p 0.01). The stem diameter parameters also showed very significant differences, namely Family (F = 2.785 p 0.01), Block (F = 353.095 p 0.01) and Family and Block Interaction (F = 2.611 p 0.01). The value of family heritability and individual heritability on plant height characters belonged to a high category with a family heritability value of 0.7213 and individual heritability value of 0.8811, while the stem diameter character for individual heritability was high with a value of 0.4406 but family heritability was moderate with value of 0.5204. The value of genetic correlation was high and positive and generally shows a greater value than the phenotypic correlation. Genetic correlation values ranged from 0.967 while phenotypic correlation values ranged from 0.8944. The highest selection priority was found in the height of the stem with a weight constant of 0.239. Predicted expected genetic gain was 3.0% for diameter parameter and 3.2% for height parameter.Objektif dari penelitian ini adalah menemukan variasi genetik, taksiran nilai heritabilitas serta peluang perolehan expected genetic gain tanaman Samama [Anthocephalus macrophyllus (Roxb.)

ABSTRACTGlyphosate has significant effects on the growth and development of plants when in underdoses. This work was developed to verify the effect of the application of glyphosate in underdoses in lignin synthesis and consequently decomposition of maize stover. Two experiments were conducted; the first one in a greenhouse for underdoses adjustments and the second one in the production area. The experimental design of the first trial was completely randomized with four replications. The treatments consisted in the application of the underdoses: 0, 25, 50 and 100 g ha-1 of glyphosate. In the production area, the experimental design was a randomized block with four replications, in underdoses: 0, 12.5, 25 and 50 g ha-1. The results were submitted to analysis of variance and regression. The underdoses of 25 g a.e. ha-1in a greenhouse promoted 36% increase in productivity of stover, in addition to increasing the lignin content in 16%, with no change in the unwanted growth of maize plants. In the production area, the concentration of 12.5 g a.e. ha-1 of glyphosate reduced the lignin content and the other underdoses have not changed this feature in maize plants. None of the underdoses affected the height and biomass produced by the maize plants. The highest underdose tested promoted acceleration in the decomposition of maize stover.

The present study aimed to analyze the initial growth of the corn hybrid AG 1051 cultivated in soil fertilized with human urine, cassava wastewater and cattle manure. The experimental design was completely randomized with four replicates and eight treatments: T1 (Control – without fertilization), T2 (HU – Human urine), T3 (CW – Cassava wastewater), T4 (BM – Cattle manure), T5 (BM + HU – Cattle manure + Human urine), T6 (BM + CW – Cattle manure + Cassava wastewater), T7 (HU + CW – Human urine + Cassava wastewater) and T8 (HU + CW + BM – Human urine + Cassava wastewater + Cattle manure). ESI (emergence speed index) and E% (emergence percentage) were determined by daily counting all seedlings emerged in a period of seven days and, at 15 DAS (days after sowing), plant height was measured. The use of cattle manure led to higher ESI and E% compared with the other treatments, as well as the variable plant height. For production variables, T5 caused highest increment in shoot dry phytomass and there were no significant differences between treatments for shoot dry phytomass. It was concluded that T4, T6 and T5 led to higher performance in the initial growth stage.

This study was conducted to find out the effect of fertilizers on the performance of two hybrids of Euphorbia as indicated by growth and flowering performance. The experimental design with controlled variables was used in the study. The use of organic fertilizers like the use of animal dungs or wastes was proven effective based on the different trials made. In terms of the effect of the fertilizers in the growth performance, there were significant differences on plant height, stem girth, number of leaves, and number of shoots during the 20th, 50th and 80th days of observations. The number of flowers was found to have significant differences in all stages. When measured during the 80th day of observation, significant differences were shown in the size of flowers. However, insignificant difference was shown in the diameter of flower bracts. As to the growth parameters, carabao manure yielded more leaves, and shoots and taller Euphorbia Orchid. It also produced bigger stem girths, wider and longer leaf sizes of Siam Ruby hybrid. As to flowering parameters, carabao manure influenced the growth of more number of flower clusters and bigger sizes of flowers of Euphorbia Orchid. On the other hand, chicken manure also influenced the growth of more number of flowers per cluster of Siam Ruby during the 50th day observation and carabao manure during the 20th day observation.

The objective of this study was to evaluate the quality of meatballs prepared with capybara meat and different concentrations of pork bacon. Three formulations of capybara meatballs were prepared: one with 100% of capybara meat and the other with 10 and 20% of pork bacon added. Coliforms were carried out at 35 and 45ºC of the meatball samples, in addition to pH, titratable acidity, moisture and ash determinations. In relation to the physical-chemical determinations, the results were submitted to analysis of variance and the differences of the means compared by Tukey test at the 5% level of significance. The results of the microbiological analyzes were evaluated in a descriptive way. The experimental design was completely randomized. All physicalchemical and microbiological determinations were performed in triplicate. Coliform analyzes showed that the meatballs were fit for consumption and the physicochemical results are in acceptable levels.
