Hancornia Speciosa

Knowledge of the mineral nutrition requirements of mangabeira (Hancornia speciosa Gomes) is relatively scarce and rudimentary because there is a lack of consistent data concerning its nutritional demands at different developmental stages. The aim of this research was to characterize the visual symptoms of macronutrient deficiencies and to evaluate the effects of these deficiencies on the growth, the production of dry matter, and the leaf content of mangabeira. To achieve this goal, a greenhouse experiment was conducted at the Goiano Federal Institute (Instituto Federal Goiano) in Rio Verde - GO, from January to June 2011 in which mangabeira plants were arranged in a random block design and grown in nutrient solutions. This experiment was replicated four times. The plants were treated with either a complete nutrient solution or a nutrient solution from which the individual macronutrient of interest (nitrogen (N), phosphorous (P), potassium (K), magnesium (Mg), calcium (Ca), or sulfur (S) had been omitted. The omission of a macronutrient from the nutrient solution resulted in morphological alterations that were characteristic symptoms of the particular nutritional deficiency and caused decreases in growth and dry matter mass production. The accumulation of macronutrients displayed the following order in mangabeira leaves: N>K>Ca>P>S>Mg.

The objective of this study was the selection of superior genotypes for growth traits, correlating them to initial height growth in the field, at age eight months. A random block design was used in the nursery, with eight clones, three replicates and four plants per plot. And a random block design was also used in the field, with eight clones, four replicate blocks and nine plants per plot. Data being analyzed in the nursery at age 120 days included: height of field seedling, at age eight months (Hc), height of nursery seedling (Hm), root collar diameter (Dc), shoot diameter (Db), shoot dry matter (PMSPA), root dry matter (PMSR), total dry matter (PMST), ratio of shoot dry matter to root dry matter (PMSPA/PMSR), Dickson quality index of root collar diameter (IQD-Dc), Dickson quality index of shoot diameter (IQD-Db). Analyses of variance showed that significant genetic differences exist among clones for all traits and, given the high heritability values found, the estimated genetic gains were generically very high. As for predicted indirect genetic gain, selection in nursery seedlings for Dc, PMSPA/PMSR, IQD-Dc provided the highest values of indirect gain in field seedling height.

It was evaluated nitrogen compounds and microbial protein synthesis in heifers fed diets containing coffee hulls (0.0; 8.75; 17.25; and 26.25% of dry matter) replacing ground corn concentrate at the following levels of coffee hulls in the total diet dry matter: 0.0, 3.5, 7.0 or 10.5%. It was used 24 crossbreed heifers (7/8, 15/16 and 31/32 Holstein-Zebu), which were distributed in a random block design made up accordingly to the weight of the animals. Spot samples of urine were colleted aproximatelly four hours after morning feeding and were used to estimate microbial protein synthesis by using urine purine derivatives. It was not observed effect of coffee hull levels in the diet on total nitrogen intake (160 g/day) and nitrogen excretion in the urine (87.4 g/day). The inclusion of coffee hull in the diet linearly increased nitrogen excretion in feces, as well as nitrogen balance. There was linear reduction in urinary excretion of allantoin, in total purine derivative and absorbed purine, which reduced 0.715, 0.873, and 0.954 mmol/day to each coffee hull unity added to the concentrate, respectively. Coffee hull altered microbial protein synthesis, which reduced in 0.687 g/day to each coffee hull unity added to the concentrate. Reduction in microbial protein synthesis can reduce weight gain in heifers fed coffee hulls.

Mineral nutrition and plant ontogeny influence both the physiological balance between nutrients in a plant and determine the proper nutritional status of a plant, which is necessary to realize the yielding potential of a cultivated species. The aim of the present study was to assess the effect of nitrogen doses (0, 4, 8, 12, 16 g N·m−2) and plant development phases (the beginning and full flowering) on the content of macroelements and changes in ionic ratios occurring in the herb of the summer savory cv. ‘Saturn’. The two-factor experiment was carried out in a random-block design with five replications. The mineral nitrogen nutrition applied increased the concentration of total nitrogen and its mineral forms in the plants. There was a change in ion homeostasis in the individual stages of the ontogenesis process, i.e., a higher content of P, K, Ca, and S in the initial flowering phase as well as Mg and Cl in the full flowering phase. The increase in the availability of mineral nitrogen in the soil solution caused a decrease in total sorption capacity, reducing the potential of the soil for saturation with alkaline cations.

Cutting Height

The objective of this study was to evaluate the nutritional traits and in vitro digestibility of silages from different corn cultivars harvested at two cutting heights. It was evaluated 11 cultivars (Dina 766, Dina 657, Dina 1000, P 3021, P 3041, C 805, C 333, AG 5011, FO 01, Dina co 9621 and BR 205) harvest 5 cm above ground (low) and 5 cm below the intersection of the first ear (high). It was used a random block design (three blocks), arranged in a 11 × 2 factorial scheme. Silages from plants harvested at high cutting height presented average content of dry matter significantly superior to silages from plants harvested at low height. Cultivars FO 01, AG 5011, Dina co 9621 and Dina 766 presented greater content of crude protein than cultivars C 805, P 3041 and P 3021, which presented the lowest contents of this nutrient. The raise in the cut height increased in vitro dry matter true digestibility coefficients and in vitro dry matter digestibility of silage evaluated. The increase in cut height improved nutritive value of silages by decreasing concentrations of fibrous fractions and increasing in vitro dry matter digestibility.

In order to research the variability of average dry matter content in onion bulbs, the trial has been set up on the experimental plot in the Centre for Vegetable Crops in Smederevska Palanka during 2000. and 2001. The trial has been performed by applying the method of random block design with five replicas. Ten cultivars of different geographical origin have been used. Examined characteristics were determined by applying the variance analysis of two-factorial trial - model 2. Hadzivukovic, 1991. The components of phenotype variance, genotype and phenotype coefficient of variance and heritability in broader sense have been calculated according to SINGH and CHAUDHARY (1976). The significant variability has been found for dry matter content in bulbs during both years of research. The researched trait had a greater genotype variance than out door conditions factor variance and the coefficient of phenotype variation greater than genetic variance coefficient. High percentage of genetic variability in total phenotype variability has been confirmed by high heritability. .

The Impact

The objective of this work was to determine the impact of cutting Tifton-85 grass at 14, 28, 42, 46, 70, and 80 days of regrowth on its production and nutritional characteristics during the rainy season. The study area of 238 m2 was divided into four sub-area, with 6 plots of 2 × 2 m spaced 1 m between plots and 2 m between sub-area. Random block design was used. The statistical analyses were performed following a randomized block design. Results were obtained as means from evaluations conducted in two consecutive years. The neutral detergent fiber (NDF) and acid detergent fiber (ADF) increased as the cutting age increased. However, crude protein, NDF nitrogen, ADF nitrogen and leaves/stem relationship decreased as the cutting age increased. The production of digestible dry matter increased linearly as the cutting age increased. Similarly, grass height, green matter and dry matter production (DMP) increased as the cutting age increased. The different cutting age did not influence the nitrogen A, B1 + B2, and B3 fractions of the grass. However, the C fraction increased as the cutting age increased. Longer intervals between cuts increased the grass productivity per cut, but compromised its nutritional composition and leaves/stem relationship. For Tifton -85, the regrowth age of 28 days allows greater production of dry matter and greater accumulated production of crude protein and digestive dry matter in the rainy season or over time.

The study presents results of a three-year experiment of variability of different potato varieties in Montenegro: early maturity varieties (Riviera), medium early (Almera, Aladin and Bounty) and medium late (Agria, Margarita, Kennebec and Desiree). The research was conducted during 2015, 2016 and 2017, in acid, brown soil and three different climatic locations: Nedakusi (556 m a.s.l.), Sutivan (680 m a.s.l.) and Orahovica (900 m a.s.l.). Field experiments were set up using standard methodology in random block design in three repetitions. The analysis of variance suggest that number of tubers per plant, mean tuber weight, yield of small tubers, marketable and total yields were significantly fluctuating depending on genotype (G), year (Y) and the location (L). In addition to individual influences of different factors, their interactions were also pronounced (G x Y, G x L, Y x L, G x Y x L). In the three-year period average, the highest total yield was recorded in Nedakusi (31.41 t ha-1), followed by Sutivan (21.35 t ha-1), while the lowest average yield (17.36 t ha-1) was recorded in Orahovica. As expected, on the three-year average, the highest percentage of dry matter was found in late varieties Agria - 25.46%, then Desiree - 25.33%, followed by Kennebec with 25.13%, while the lowest percentage of dry matter was found in medium early variety Almera - 20.82%. The highest average yield of tubers in the three-year period was recorded in the Aladin variety, followed by Agria and Desiree, while the lowest average yield was recorded in the variety Riviera. Obtained results show that the highest yields over observed locations were recorded in medium early varieties that formed high number of tubers per plant (Aladin) and medium late varieties (Desiree and Agria) give satisfactory and stable yields.

AbstractGenome-wide selection (GWS) has been becoming an essential tool in the genetic breeding of long-life species, as it increases the gain per time unit. This study had a hypothesis that GWS is a tool that can decrease the breeding cycle in Jatropha. Our objective was to compare GWS with phenotypic selection in terms of accuracy and efficiency over three harvests. Models were developed throughout the harvests to evaluate their applicability in predicting genetic values in later harvests. For this purpose, 386 individuals of the breeding population obtained from crossings between 42 parents were evaluated. The population was evaluated in random block design, with six replicates over three harvests. The genetic effects of markers were predicted in the population using 811 SNP's markers with call rate = 95% and minor allele frequency (MAF) > 4%. GWS enables gains of 108 to 346% over the phenotypic selection, with a 50% reduction in the selection cycle. This technique has potential for the Jatropha breeding since it allows the accurate obtaining of GEBV and higher efficiency compared to the phenotypic selection by reducing the time necessary to complete the selection cycle. In order to apply GWS in the first harvests, a large number of individuals in the breeding population are needed. In the case of few individuals in the population, it is recommended to perform a larger number of harvests.
