In on hand, the cultivation of grapes in Brazil is more typical in regions with milder climate and also historical value in the winery production. In the other hand, the Northeast region of Brazil stands out more and more in the production and marketing of wines, especially in the semi-arid region of the São Francisco River Valley. With this, there is a significant increase in the areas of cultivation and productivity of the same, conditioning a demand for new areas of cultivation. The objective of this thesis was following the different phases of the grape for wine production in a non - traditional wine region in the Northeast of Brazil, the agronomic parameters and the final quality of the grape. Ten varieties of vines were studied for the elaboration of fine wines, three of them for the elaboration of white wines - Suavignon Blanc, Chardonnay e Muscat Petit Grain and seven for red wine - Cabernet Sauvignon, Pinot Noir, Petit Verdot, Merlot, Malbec, Viognier e Syrah. In the production, Merlot Noir (13.5 t ha-1) and Muscat Petit Grain (9.5 t ha-1) were evaluated in the phenotype evaluation of Muscat Petit Grain varieties (120 days) as precocious and Merlot Noir varieties and Cabernet Sauvigon (144 days) as the latest. For the thermal requirements the Pinot Noir and Cabernet Sauvignon varieties both with requirements of 1,077.28 GD for complete development. The physical and chemical characteristics of the bunches were also evaluated. Based on the results of the research, the Muscat Petit Grain, Petit Verdot, Malbec and Cabernet Sauvignon varieties presented good productivity characteristics that could increase the producer's yield in winemaking and physico-chemical characteristics that will directly influence the final quality of the wine, such as pH and acidity. Indicating good adaptation and potential for the region and the Syrah variety presented higher soil MBC value (313.5 mg dm-3).

Synthetic insecticides are the main control tool. However, the crucifer's moth has developed high levels of resistance for all classes of insecticides. The objective of this research was to verify the susceptibility of diamondback moth populations to Brilhante® (Metylcarbamate oxine, Premio® (Chlorantraniliprole) and Dipel® (Bacillus thuringiensis var. Kurstaki) insecticides, as well as to investigate their behavioral response when in contact with the evaluated pesticides. Populations of diamondback moth from the municipalities of Camocim de São Félix - PE, Lajedo - PE, Sairé - PE, Bezerros - PE, Venda Nova do Imigrante - ES, Viçosa - MG (Laboratory) and Recife - PE (Laboratory) were studied. The experiments focused on larval susceptibility of the pest by ingestion of cabbage discs treated with insecticides. The parameters of the behavioral activity (walking distance, walking time, mean velocity, number of stops and rest time) were evaluated in the populations of Camocim de São Félix - PE, Sairé - PE, Lajedo - PE, Recife - PE and Viçosa - MG. Surfaces treated and untreated with neurotoxic insecticides (Methylcarbamate and Chlorantraniliprole) were used. Resistance ratios for insecticides were found by dividing the LD50 of the population assessed by the LD50 of the most susceptible population. Mortality data were submitted to Probit analysis. The suitability of the Probit analysis model for all the populations tested for the insecticides Chlorantraniliprole and B. thuringiensis was checked. However, it was verified that the model was not adequate for the field populations of Camocim de São Félix, Sairé, Lajedo and Bezerros when the Brilhante® (methylcarbamate oxine) insecticide was tested due to the low mortality caused by the insecticides in these populations. The population of Camocim de São Félix - PE, presented the highest Resistance Ratio (322.5 times) when compared to the population of Viçosa - MG for the insecticide Premio® (Chlorantraniliprole) at LD50. Field populations in the Agreste region of Pernambuco presented the highest LD50. Similar results were observed for the insecticide Dipel ® (Bacillus Thuringiensis var. Kurstaki), the population of Recife - PE being the most susceptible. Again, the population of Camocim de São Félix - PE followed by the population of Sairé showed the highest LD50s and the highest Resistance Ratios (4.26 and 2.59 times). In relation to the insecticide Brilhante®, it was verified that the population of Recife - PE (LD50 = 8.34 mL L-1) was more resistant than the population of Viçosa - MG (LD50 = 3.19 mL L-1). For the results of the behavioral parameters, it was verified that all the populations of diamondback moth evaluated had behavioral changes when exposed to the area treated with the insecticides. Thus, it was verified that the field populations of the insect pest presented significant levels of resistance for the insecticides Premio®, Brilhante® and Dipel®, in addition to changes in behavioral parameters that contribute to the reduction of insecticides efficacy.

With the increase of commercial fertilizer values the use of sludge from the sewage treatment plant became an alternative. The use of dairy industry residues as fertilizers as well as the determination of the correct dosage can provide subsidies for sustainable production without compromising the environment. The objective of the present study was to evaluate the use of dairy industry sludge in the sorghum grown in a greenhouse. The experiment was carried out in pots with a capacity of 20L in a greenhouse at the Federal Rural University of Pernambuco - UAG, from September to December 2018. The studied culture was the sorghum. As experimental design, a randomized complete block design was adopted. - DBC with 7 treatments in 4 blocks, totaling 28 experimental units. Dairy sludge doses were sized according to the subsurface application rate defined by resolution 375/2006 - CONAMA, the following doses were: T1 - (0% - control); T2 - 50% (1.5 L sludge / vessel); T3 - 100% (3.0 L sludge / vessel); T4 - 150% (4.5 L of sludge / vessel); T5: 200% (6 L sludge / vessel); T6 - (NPK - additional); T7: (PKL = T3 + PK - additional). In the treatments with mineral fertilization, the rates of N, P2O5 and K2O were determined according to the recommendation of fertilization of the State of Pernambuco. Soil ADF, physiological variables were evaluated: photosynthesis, transpiration rate, stomatal conductance, chlorophyll a and b, enzymes of CAT plant, APX and SOD, leaf and panicle N, leaf C, height, diameter and dry mass. Increasing doses of sludge and PKL control increased soil microbial activity. The treatments 0% and NPK presented higher increase in the activity of the enzyme SOD. The photosynthetic rate, transpiration rate and stomatal conductance variables did not present significant differences. Increasing doses of sludge provided larger increases for chlorophyll a and b. The addition of sludge doses increased the leaf N and C and panicle N, and its use was efficient when used as mineral supplement. Increasing sludge doses provided higher averages for the height and diameter variables. Increasing doses of sludge contributed to the largest increases in dry mass.

It is used in various ways in animal feed because it has good digestibility and has high energy potential, mainly due to high biomass production. It has good adaptability to the semiarid climate, although it varies in production over the years. Irrigation provides stability in crop yield and provides better conditions for soil microbial activity. Soil microorganisms reflect as quality indicators, being associated with several biogeochemical processes, besides being sensitive to environmental changes. The present work aimed to evaluate the changes in biological attributes indicating soil quality in the Brazilian semiarid, due to the influence of irrigation management on different Pennisetum purpureum genotypes and seasonal variations. The study was carried out at the experimental farm of the University Federal Rural of Pernambuco, in Garanhuns-PE. The area was arranged in a randomized block design with factorial scheme. The treatments consisted of a combination of two elephant grass cultivars (Elephant B and Mott), two irrigation regimes (with and without irrigation) and two climatic periods (dry season and rainy), with three repetitions. Two collections were carried out in July and December 2017, corresponding to the rainy and dry season, respectively. Rhizospheric soil samples were collected at a depth of 0-10 cm. Key biological indicators such as microbial biomass carbon (CBM), soil basal respiration (RBS), metabolic quotient (respiration / biomass ratio), and soil enzymatic activity were evaluated. Microbial biomass carbon and basal respiration had higher values in the genotype Mott. Irrigation management presented lower RBS in the rainy season and CBM was significant only in the genotype Elephant B in both evaluated seasons. The metabolic quotient did not differ between treatments. The use of irrigation presented higher enzymatic activities in both evaluated periods, except for urease activity and FDA in the rainy season. The genotype Mott showed higher soil enzymatic activities, except for β-glucosidase and acid phosphatase in the rainy season. According to the results obtained, in the soils examined, the increase of soil water content by drip irrigation management in the dry period can improve the nutrient cycling potential, helping to maintain the biological and chemical fertility of soils in semiarid agroecosystems. Genotype Mott has better biological attributes in soil quality, providing better microbial activities regardless of the evaluated seasons and different irrigation managements. Seasonality may alter soil microbial community, considering structure and functionality. It is of fundamental importance that works like this continue to be developed, to understand if these communities can adapt to these environmental changes and if from this change the enzymatic activities will be kept in the soil.
