This study evaluated the forage mass, plant height, chemical composition and chlorophyll index of signal grass (Brachiaria decumbens cv. Basilisk), as well as the content of organic matter (OM) in soil under increasing levels of nitrogen. The experiment was conducted in the Rio Manso Farm, experimental unit of the Federal University of the Jequitinhonha and Mucuri Valleys - UFVJM in the municipality of Couto de Magalhães de Minas, state of Minas Gerais. For plant evaluation, we use a split plot randomized block design with four replications. Nitrogen levels (0, 25, 50, 75, 100 kg ha-1 N) were assigned to plots and the cuts made in plants, to subplots. For the assessment of soil organic matter, we used a split-split-plot, with nitrogen levels (0, 25, 50, 75 and 100 kg ha-1 by cut) in the plots, collection depth (0-10 and 10-20 cm) in the subplots and three sampling times (before the onset of the experiment, at the end of the 1st crop year and at the end of the 2nd crop year) in sub-subplots in a randomized block design with four replications. It can be concluded that nitrogen fertilization linearly increases forage mass, plant height and crude protein content of signal grass, which are positively correlated with chlorophyll index. At the end of two agricultural years, the content of organic matter in the soil decreases, which can be attributed to management of cutting and removal of the cut material.

The objective of this study was to evaluate the yield and physiological quality of bean seeds in two agricultural crops, and the chemical composition of seedlings submitted to adverse temperatures during germination. For the field experiment, a randomized block design was used, using five genotypes, BRS Embaixador, IPR Tuiuiú, Guabiju, Carioquinha and Mouro, arranged in four replicates. The experimental units were composed of five lines with five meters in length, where 25 plants were randomly collected per experimental unit to measure the characters of interest. For laboratory testing the seeds produced were submitted to three temperatures (15, 25 and 35°C) during germination under controlled conditions. The evaluated characters were: grain yield, mass of a thousand seeds, germination, first germination count, starch content, soluble sugar, soluble protein and total amino acids. The data were submitted to analysis of variance and later compared by the Tukey test. Yield per plant revealed changes between the agricultural crops, as well as among the genotypes tested. Germination and the first germination count revealed higher magnitudes in seeds produced by BRS Embaixador, IPR Tuiuiu and Carioquinha genotypes. For all genotypes, protein and amino acid levels were higher in seedlings submitted to lower temperatures. The levels of starch and total soluble sugars were higher in seedlings produced at 35°C. Yield, seed physiological quality and chemical composition of seedlings are influenced by the crop and genotypes tested.

ABSTRACT The effect of four nitrogen levels (0, 40, 80 and 120kg N ha-1), applied before deferment on the beef cattle production and structural variables on Urochloa decumbens (signal grass) were assessed from January to October 2012 and from January to September 2013. A randomized block design with three replicates was adopted, in an arrangement of repeated measures in time (grazing period). An interaction effect between nitrogen level and grazing period was observed on extended-plant height and herbage mass. As the nitrogen levels were increased, extended-plant height, herbage mass, total herbage allowance, and efficiency of conversion of fertilizer into herbage were increased. Throughout the grazing period, pasture height, extended-plant height, percentage of leaves, herbage and morphological components allowance, and percentages of leaves and stems in the herbage apparently selected by the animal decreased. Nitrogen levels had no effect on average daily gain or gain per area in the first year. A fixed deferment period with increasing levels of nitrogen fertilization on signal grass pastures does not influence the average daily gain per animal, reduces the efficiency of the nitrogen fertilizer and negatively changes the structural characteristics of the pasture.

This study aimed to explore the effect of Siam weed (Chromolaena odorata)  green manure application on the growth and development of mustard (Brassica juncea) in Kelimutu National Park, Indonesia.  The study was carried out between September and November 2010 in Ende district on the island of Flores, Indonesia, at an altitude of 1500 to 1730 meters above sea level. This study used a randomized block design with four treatments: K0: No Siam weed application, K1: 5 tons/ha Siam weed (2.8kg/plot), K2: 10 tons/ha Siam weed (5.6kg/plots), K3: 15 tons/ha Siam weed (8.4kg/plot), K4: 20 tons/ha Siam weed (11.2kg/plot). Researchers observed plant characteristics (plant height, leaf area, wet weight and number of leaves) and soil fertility indicators (Organic carbon).  Plant organic matter was ground and subsequently analyzed for nutrients using a randomized block design along with lab analysis for soil fertility. The results of this study showed that the application of Siam weed organic matter had no significant effect on mustard plant height, leaf number, leaf area, or wet weight. However, it was found that organic matter application did have a significant effect on soil fertility indicators (organic carbon), and caused an increase in soil organic matter content.

Intercropping soybean with corn on dry land with dry climate (DLDC) is an alternative program to expand the soybean cultivation harvested area. This study evaluated the effectiveness of fertilization performance in the intercropping of soybean-corn in DLDC. The experiment in this study was arranged in a randomized block design, consisting of seven fertilizer package treatments with four replications. The spacing between corn (Pertiwi 3) and soybean (Dena 1) was (50 cm x 200 cm) x 40 cm (2 plants/clump) and between soybeans (Dena 1) was 40 cm x 15 cm (2-3 plants/clumps). The observations consisted of soil analysis (pH, organic matter, total N (Kjeldahl), available P, Ca-dd, Mg-dd, K-dd, and Na-dd), soybean leaf chlorophyll index (45 and 60 days after planting/dap), plant height at (45 daps and harvest), number and weight of root nodules (45 daps); Corn: chlorophyll index (56 daps), plant height (harvest), analysis of corn and soybean plant tissue (60 daps), yield, and yield components of dry seeds of soybean and corn per hectare. The results showed that effective fertilization for the intercropped crops was 53 kg N + 1,500 kg of manure per hectare in corn plant and 7 kg N + 22 kg P2O5 + 18 kg K2O + 1,500 kg/ha manure + Rhizobium Iletrisoy/Agrisoy in soybean crops.

This study aimed at evaluating the morphogenic and structural characteristics of Panicum maximum Jacq. cv. Aruana, as well as its chemical composition after submitting it to different nitrogen levels. The experiment was performed by adopting a randomized block design which included four treatments (0, 75, 150 and 225 kg ha-1 of N) and three replications, in 100 m2 plots. Twice a week, for the 63 days of regrowth, the morphogenic characteristics were determined and estimated, after which the chemical composition was assessed. The aruana grass revealed a quadratic and positive response to the nitrogen fertilization, and showed a remarkable rise in the elongation rates, leaf appearance and senescence, besides the number of live leaves per tiller and final leaf length. However, the nitrogen fertilization reduced the phyllochron and leaf life in the aruana grass, implying the direct effect of nitrogen on the flow of tissues. A quadratic and positive effect of the nitrogen fertilization was observed for the dry mass production, from 5,840.80 kg ha-1 for plants lacking the nitrogen fertilization to 8,862.55 kg ha-1 for those fertilized with 225 kg ha-1 of N. Thus, while the nitrogen fertilization positively affected both tillering and morphogenesis, the N doses used in this study were insufficient to induce any change in the chemical composition of the aruana grass.
