The management of organic materials in vine ( Vitis vinífera L cv Malbec) is important when working with winter manure or cattle manure, which activates the surface rootless but this type of organic matter is restricted to use it in fields far from the sources of fruit processing therefore the we need to develop other organic matter sources with the same effects. For this reason this research evaluates the influence of hums from vermiscompost (V) elaborated by Eisenia foetida on the productive yields of vine on sandy soils (Aridisol) in Ica, Peru. The experiment used a randomized complete block design (DBCA) with four replications and four treatment base on the doses of V and they were T1 which is the control with no V; T2 is 1.5 t ha –1 of V; T3 is 2.5 t ha –1 of V and T4 is 3.5 t ha –1 of V. For the analysis of variance (ANOVA) SAS statistical software was use. The results obtained did not show statistical differences between the average production but there was a tendency to increase production with applications of 2.5 t ha –1 with yields of 12807 kg ha –1 while the control with no V being the treatment with the lowest production. Pearson’s Correlation Coefficient analysis indicates that there is a moderate positive association (r = 0.5) and a relation with linear approximation between the quantitative variables. In conclusion, the result of the mathematical model resulting from the linear regression equation indicated that for each additional kg of vermicompost can be expected an increase of 1.43 kg of vine.
葡萄藤(Vitis vinífera L cv Malbec)中有机材料的管理很重要，当使用冬季粪便或牛粪时，它们会激活表面无根，但这种类型的有机物质仅限于在远离水果加工来源的田地中使用，因此我们需要开发具有相同效果的其他有机物质来源。因此，本研究评估了秘鲁伊卡沙质土壤(Aridisol)上由爱森尼亚(Eisenia foetida)制作的蚯蚓堆肥(V)对葡萄生产产量的影响。试验采用随机完全区组设计(DBCA)， 4个重复，4个处理，以V的剂量为基础，分别为T1，即无V的对照;T2是1.5 t ha -1 (V)T3为V的2.5 t ha -1, T4为V的3.5 t ha -1。方差分析采用SAS统计软件。结果表明，平均产量之间没有统计学差异，但施用2.5 t hm2 -1有增产的趋势，产量为12807 kg hm2 -1，而不施用V的对照产量最低。Pearson相关系数分析表明，定量变量之间存在中度正相关(r = 0.5)，并与线性近似相关。综上所述，由线性回归方程建立的数学模型结果表明，每增加1 kg蚯蚓堆肥可预期增加1.43 kg藤蔓。

Intercropping is a cultivation system that aims to achieve high productivity per unit area and promote the sustainability of the production system. The objective of this work is to evaluate the agronomic viability and economic profitability of intercropping taro with okra plants. The research was conducted in an experimental field between October 2011 and June 2012. In total, nine treatments from four intercrops of taro with okra plants were evaluated: okra was planted at two time points, 0 days and 30 days after the taro planting, and two arrangements of okra plants, one plant at 30 cm and two plants at 60 cm. We used a randomized block experimental design with four replications and determined the indexes of SPAD, LAI, K, and the productivity and economic indexes. The intercropping systems were agronomically viable by presenting a Land Use Efficiency (LUE) value above 1. When okra was intercropped at the same time as taro, the best results for Profitability Index (PI), economic yield, and Rate of Return (RR) were achieved. The treatment with one okra plant at 30 cm, intercropped at 0 DAP (Days After Planting) taro presented the best results for RR and PI.

In this study, Bacillus subtilis were applied on seeds, seedlings, and tomato crops for two years in an organic system. The product Serenade ® was used on ‘Cardyna’ and ‘Trinidade’ cultivars with the objective of determining the effect of the bacteria on initial plant growth when applied to seeds (50 μL per seed) or the seedlings watered with 100 mL solution at 8 mL L –1 concentration, and tomato yield when applied at the concentration of 4 mL L –1 in the form of a soil drench, foliar sprays and their combination, considering their action in the promotion of growth and also in the induction of resistance allied to possible metabolic deviations. Seed application reduced initial plant growth, while seedling watering at transplanting promoted growth. Chlorophylls a , b and total chlorophyll, carotenoids, and the enzymes phenylalanine ammonia lyase, chitinase, and β 1,3 glucanases were stimulated in a variable way among cultivars and applications, indicating the activation of plant defenses. Phenolic compounds, flavonoids, and total sugars were not altered, while the concentrations of reducing sugars were higher due to applications than those of non- reducing sugars. The metabolic changes did not influence the tomato yield.
在本研究中，枯草芽孢杆菌在一个有机系统中施用于种子、幼苗和番茄作物两年。Serenade®产品用于‘Cardyna’和‘Trinidade’品种，目的是确定在种子(每粒种子50 μL)或幼苗用100 mL浓度为8 mL L -1的溶液浇灌时，细菌对植物初始生长的影响，以及在土壤淋水、叶面喷雾剂及其组合的4 mL L -1浓度下，细菌对番茄产量的影响。考虑到它们在促进生长和诱导与可能的代谢偏差相关的抗性方面的作用。播种降低了植株的初始生长，而移栽时浇水促进了幼苗的生长。叶绿素a、b和总叶绿素、类胡萝卜素以及苯丙氨酸解氨酶、几丁质酶和β 1,3葡聚糖酶在不同品种和施用中受到不同方式的刺激，表明植物防御被激活。酚类化合物、黄酮类化合物和总糖没有改变，而还原糖的浓度由于施用而高于非还原糖的浓度。代谢变化对番茄产量没有影响。

. ABSTRACT The objective of this work was to quantify damage and yield losses in lettuce parasitized by Meloidogyne javanica , as well as the growth characteristics of naturally cultivated field plants infested by this pathogen. The experimental area consisted of four seedbeds of 10.0x1.60 m cultivated with 160 plants in each, totaling 640 plants. The damages and yield loss were quantified in four evaluations (Ev1, Ev2, Ev3, and Ev4), with each evaluation corresponding to a cultivation cycle. The four plantings were made in the consecutive form. The fresh mass weight and dry mass weight (FMW and DMW, respectively), gall number (GN), and final population of the nematodes (FP) were evaluated. The population increase of M. javanica caused a reduction in the FMW and DMW in all evaluations. In Ev1 and Ev2, 100% of the plants were commercialized. In Ev3 and Ev4, 7% and 65% of the plants, respectively, could not be commercialized. The Ev4 was completely unviable since the produce had losses of U$ 7.42; U$ 23.19 and U$ 1,484.10 for the cultivation of 640; 2,000 and 128,000 plants, respectively. The economic threshold in Ev4 was 10,151 nematodes/plant or 109 galls/plant.

The cultivation of bell peppers, before transplanting, starts in nurseries to obtain uniform and vigorous seedlings. This study aimed to evaluate the effect of applying magnetically treated water on germination and the initial growth of bell pepper seedlings. Two experiments were conducted from August to October 2018 in a protected environment at the Irrigation Tecnic Center (CTI/ UEM) – Maringá, Paraná: the first in 50-cell polyethylene trays and the second in plastic containers (180 ml). Both experiments were filled with a commercial substrate (Su) and commercial substrate + soil mix (SS). The substrate was irrigated daily for the germination test, according to the corresponding treatment, and germination was quantified in the first 15 days after emergence to obtain the germination percentage and the final emerged percentage. Seedling growth was evaluated based on the following criteria at 43 days after sowing: height, stem diameter, total fresh mass, total dry mass, chlorophyll A and B, and carotenoids. The results showed that the application of magnetically treated water to seeds promoted germination one day prior to those irrigated without treatment when cultivated with SS. There was significant interaction for the chlorophyll A, with a 42% increase in SS cultivation with the application of magnetically treated water compared to the application of non-treated water. For the other variables, there were significant responses only in SS cultivation. Application of magnetically treated water caused higher gravimetric humidity in three out of ten evaluations, showing a significant reduction of evaporation in Su and SS cultivation.

The reduction of water quality typically starts in small streams and rivers; tributaries interconnected to major rivers. In this regard, this study aimed to investigate waste disposal of small wine and liquor agribusinesses by monitoring the water quality of two streams, tributaries of the Soturno and Jacuí rivers, located in the Quarta Colônia region the state of Rio Grande do Sul (RS), Brazil. We began monitoring water quality in July 2008 and continued uninterruptedly until May 2009. We collected water samples at three different locations (source, upstream, and downstream) in triplicate, totaling 162 samples. We investigated 24 variables that makeup chemical, physical and biological parameters of water quality. With the results, we concluded that the diffuse sources of pollution in the “Liquor stream” are associated with wastewater of small agribusinesses and nearby residences, in contrast, the source of the “Wine stream” showed the most chemical changes in water quality, and whose diffuse sources of pollution are more associated with agricultural activity than the small agribusinesses activity. The variables of chemical and biological oxygen demand, dissolved oxygen, total iron, total manganese, and total phosphorus presented values higher than those of Class II waters in both streams. Therefore, small agribusinesses need to adequately dispose of the waste in order to meet existing legislation comprehensively.
水质的下降通常始于小溪和河流;与主要河流相连的支流。在这方面，本研究旨在通过监测位于巴西南里约热内卢Grande do Sul (RS) Quarta Colônia地区的Soturno河和Jacuí河的两条河流的水质，调查小型葡萄酒和白酒农业综合企业的废物处理情况。我们于2008年7月开始监测水质，一直持续到2009年5月。我们在三个不同的地点(源头、上游和下游)采集了三份水样，共计162份。研究了构成水质化学、物理和生物参数的24个变量。研究结果表明，“酒流”的扩散污染源主要与小农企业和附近居民的废水有关，而“酒流”的水质化学变化最大，其扩散污染源与农业活动的关系大于与小农企业的关系。化学和生物需氧量、溶解氧、总铁、总锰、总磷等指标均高于二类水体。因此，小型农业企业需要充分处理废物，以全面满足现行立法。
