ABSTRACT: Mahanarva fimbriolata (Stål) (Hemiptera: Cercopidae), the sugarcane spittlebug, is one of the most important pests of this crop in Brazil. The magnitude of its damage depends on the pest population, the plants size when they are infested and the cultivar tolerance. The knowledge about those parameters allows the elaboration of the spittlebug management matrix, in which small plants and less tolerant varieties fields are prioritized for sampling and controlling in relation to developed plants and tolerant varieties fields. Therefore, this study aimed to evaluate the response of sugarcane genotypes to M. fimbriolata, so that they can be correctly allocated in the management matrix. Two experiments were carried out under laboratory conditions using a randomized block design with treatments in a factorial arrangement of 2×11 (experiment 1) and 2×21 (experiment 2), with six (experiment 1) or five replicates (experiment 2). The first factor included two levels of infestation (infested and noninfested plants with spittlebugs), while the second consisted of the cultivars. Cultivars IACSP01-5503, CTC 9004 and RB925211 were considered tolerant to spittlebug, they did not show significant reductions in aboveground biomass, despite showing symptoms of pest attack, as leaves yellowing, while CV6654 and IACSP01-3127 were the least tolerant cultivars, showing the highest reduction in aboveground biomass due to M. fimbriolata infestation. Thus, CV6654 and IACSP01-3127 should be prioritized for sampling and control over the others. On average, spittlebug infestations caused 30.9 % of reduction of aboveground biomass.

Development of the population and the increasing demand for health services has led to the increase in the number of hospitals, both government hospital and privet hospitals. The presence of ammonia as a result of protein decomposition can be toxic in the waters. The application of anoxic-oxic biofilter system is an attempt to be able to reduce ammonia levels in hospital wastewater. In the process of anoxic-oxic biofilter, contact occurs between the gravel media and microorganism to form biofilms which can accelerate the degradation of organic matter and the nitrification process. This study aims to obtain the best activated sludge source in reducing ammonia levels of wastewater applied to the anoxic-oxic biofilter system applied. This research was contucted in two stages in which the first stage of active mud nursery was carried out from three sources, namely WWTP Wangaya Hospital Denpasar, WWTP of PTN Hospital Udayana University and WWTP of Bangli Hospital for six days. At this stage a Mixed Liquor Volatile Suspended Solid (MLVSS) value is measured which shows the growth rate of biomass in activated sludge. The second stage is applivation of avtivated sludge and control to the anoxic-oxic biofilter system to reduce ammonia levels in hospital wastewater for five days of processing. This study use a randomized block design with four treatments and three replication. The results showed that the best activated sludge was obtained through nursery from WWTP of Wangaya Denpasar Hospital which was shown by the highest biomass growth (MLVSS Value) of 2433.3 mg/L and the highest reduction in ammonia reached a final level of 0.53 mg/L. The levels of effectiveness of the process of decreasing ammonia levels by 94.70% and has been able to pass the specified quality standard effectiveness percentage (90%) for five days of processing. The value of this effectiveness is the highest compared to the controls and other activated sludge treatment.

ABSTRACT The cultivation of cowpea [Vigna unguiculata (L) Walp] can be an important alternative in succession to maize in areas of degraded pastures due to the use of residue from fertilizers . With this, we aimed to evaluate the productivity of cowpea as a successor culture to undergo corn doses of reactive natural phosphate Arad and combinations with NPK. The experimental design was a randomized block design in a split plot with four replications. The fertilizer was applied in previous cultivation (crop) using four phosphate doses in the form of Arad natural phosphate: 50, 100, 200 and 300 kg ha-1 of P2O5 and the sub-plots in combination with NPK, NK, NK + liming, and control (no liming and fertilizer). The cowpea yield components were evaluated in this work. The residues of P2O5 from the natural phosphate increased the phosphorus content in the plant and influenced the number of grains per pod. The residual effect of NK+ liming and only NK showed better results for the variables grain yield, number of pods per plant, number of seeds per pod and dry mass of aerial part. The residual effect of NPK showed better results for the mass of 100 grains.

ABSTRACT Propagation of “coquinho-azedo” (Butia capitata) is limited due to dormancy and high incidence of fungi in its seeds. The aim of this study was to evaluate the effect of treating “coquinho-azedo” seeds with different concentrations of bactericide and/or fungicide on the incidence of fungi and on the germination of seeds. Thus, B. capitata seeds were immersed in four doses of the bactericide kasugamycin (0, 1.5, 3.0 and 4.5 mL/L) and/or in four concentrations of the fungicide carbendazim+ thiram (0, 2.92, 5.84 e 8.75 mL/Kg), totaling 16 treatments. After the treatments, the operculum was removed from the seeds, which were placed on trays containing autoclaved sand, covered with transparent plastic film and kept in the nursery. In the germination test, treatments were distributed in randomized block design, factorial arrangement of 4x4 (bactericidal doses x fungicide doses), with four replicates of 50 seeds per plot. For the test of seed health quality, the Blotter test was employed in completely randomized design, using 20 replicates and 10 seeds. Health quality and germination were evaluated at 15 and 40 days after the treatment of seeds, respectively. There was no interaction between the bactericide and the fungicide on germination and control of fungi associated with seeds. However, there was an effect of fungicide concentrations on the evaluated parameters. We observed a negative correlation between the concentrations of the fungicide carbendazim + thiram and fungal incidence, and a positive correlation between the fungicide concentrations and seed germination. Therefore, fungicide treatment reduces the fungal incidence and provides better germination of B. capitata seeds.

Shallot (Allium ascalonicum Linn.) constitutes one of the commodities that has important meaning for Indonesian people with the limiting factor in the production is the pest attack. One of these pest control techniques is by controlling technical culture of polyculture planting system. This research was conducted in July to October 2019 which was located in Banyuputih Village, Wringin District, Bondowoso Regency. This study used a Randomized Block Design (RBD) with six treatment, namely: P1 = polyculture of shallot + Lemongrass; P2 = polyculture of shallot + celery; P3 = Polyculture of shallot + mustard; P4 = Polyculture of shallot + Lemongrass + mustard; P5 = Polyculture of shallot + celery + mustard; P6 = Monoculture of shallot. Each treatment was repeated 4 times. Observation started at 30 days after planting. Data collection was done by observing directly on the sample plants. Sampling was carried out using Yellow trap and pit fall trap. Samples were taken at each plot 10 times with intervals of 4 days. Observations included collecting the pest insects and natural enemies that were found, counting the number of populations in each species, scoring towards the damage plants. The results showed that shallot planting by polyculture with different types of plants affected the population of pests and natural enemies as well as the level of diversity of insects in shallots. Planting shallots by polyculture has been proven to control pest populations compared to planting shallots by monoculture. Polyculture planting with two types of plants proved to be better than polyculture planting with three types of plants where the best treatment was found in P1, namely polyculture of shallot and lemongrass with the smallest pest population which was 17.5.

Sweet sorghum is currently an important alternative for ethanol production in sugar cane off-season. In this study was to evaluate the effects of plant arrangements and the application of atrazine and S-metolachlor on growth and productivity of sweet sorghum. An experiment was conducted in randomized block design and, arranged in split plots with four repetitions. Plots consisted of spacing (0.25 m, 0.45 m 0.45-0.45-0.90 m) and sub-plots of weed control methods - atrazine (2000 g ha-1), atrazine + S-metolachlor (2000 + 720 g ha-1), atrazine + S-metolachlor (2000 + 960 g ha-1), atrazine + S-metolachlor (2000 + 1200 g ha-1), atrazine + S-metolachlor (2000 + 1440 g ha-1). Besides that, manual hoeing control was added. The intoxication of sorghum plants and weed control was evaluated at 7, 14 e 28 days after herbicides application (DAA). Plant height, stem diameter, total fresh matter, juice mass and total soluble solids (°Brix) were evaluated at 120 days after crop emergence (DAE).  There was no interaction between the factors spacings and control method for variables total matter fresh (TMF), height (H), stem diameter (D), juice mass (JM), and Brix. Application of the mixture (atrazine + S-metolachlor) in the highest doses reduced total fresh matter and °Brix. The spacing of 0.25 m provided the highest productivity of fresh matter, juice mass and increased the °Brix. The application of mixture (atrazine + S-metolachlor) controlled 90% of the weeds at 28 days after application. The increasing in doses of S-metolachlor elevates the intoxication in sorghum plants. The mixture (atrazine + S-metolachlor) has a potential for use in weed control in sweet sorghum, but at doses below 960 g ha-1 of S-metolachlor. metolachlor.
