The fuzzy logic is an efficient tool for simulation and validation of new technologies in agriculture. The objective of the study is to adapt the fuzzy logic model for simulation of biomass and oat grain yield by nitrogen involving the nonlinearity of the maximum air temperature in the conditions of use of the biopolymer hydrogel, considering high succession systems and low release of residual N. The study was conducted in 2014 and 2015, in a randomized block design with four replicates in a 5 x 5 factorial. Five hydrogel doses (0, 30, 60, 90 and 120 kg ha-1) were added in the groove next to the seed; and 5 doses of N-fertilizer (0, 30, 60, 90 and 120 kg ha-1) applied at the fourth expanded leaf stage, respectively. The cultivar was URS Corona. The pertinence functions and the linguistic values established in the input and output variables to simulate the biomass yield and oat grains in the succession systems are adequate observed productivity. The fuzzy model makes it possible to estimate the biomass and oat grains productivity efficiently under the conditions of use of the hydrogel as a function of the nitrogen doses and maximum air temperature, adding to the existing models of simulation.

ABSTRACT Fuzzy logic can simulate wheat yield by nitrogen and temperature nonlinearity, validating the use of hydrogel biopolymer. The objective of this study is to adapt the fuzzy logic model to the simulation of nitrogen biomass and wheat grain yield and non-linearity of the maximum air temperature, under the conditions of use of the hydrogel biopolymer, in high and low N-residual release systems. The study was conducted in 2014 and 2015, in Augusto Pestana, RS, Brazil (28 ° 26 ‘30’ latitude S and 54 ° 0 ‘58’ longitude W). The experimental design was a randomized block design with four replications in 5 x 5 factorial, for hydrogel doses (0, 30, 60, 90 and 120 kg ha-1), added in the furrow next to the seed, and N-fertilizer doses. (0, 30, 60, 90 and 120 kg ha-1), applied at the phenological stage V3 (third expanded leaf) as top-dressing, respectively. The pertinence functions together with the quantitative and linguistic values for the input and output variables are suitable for the use of fuzzy logic in the wheat yield simulation. The fuzzy model made it possible to estimate the values of biomass and wheat grain yield by nitrogen and non-linearity of the maximum air temperature under the conditions of use of the hydrogel biopolymer in high and low N-residual release systems.

ABSTRACT Fuzzy logic can simulate wheat productivity by assisting crop predictability. The objective of the study is the use of fuzzy logic to simulate wheat yield in the conditions of nitrogen use, together with the effects of air temperature and rainfall, in the main cereal succession systems in Southern Brazil. The study was conducted in the years 2014, 2015 and 2016, in Augusto Pestana, RS, Brazil. The experimental design was a randomized block design with four repetitions in a 4 x 3 factorial scheme for N-fertilizer doses (0, 30, 60, 120 kg ha-1) and nutrient supply forms [100% in phenological stage V3 (third expanded leaf); (70%/30%) in the phenological stage V3/V6 (third and sixth expanded leaf) and; fractionated (70%/30%) at the phenological stage V3/E (third expanded leaf and beginning of grain filling)], respectively, in the soybean/wheat and corn/wheat systems. The pertinence functions and the linguistic values established for the input and output variables are adequate for the use of fuzzy logic. Fuzzy logic simulates wheat grain yield efficiently in the conditions of nitrogen use with air temperature and rainfall in crop systems.

ABSTRACT: Currently, biomonitoring is a methodology used to verify the environmental impact of new technologies in the agricultural environment, highlighting edaphic entomofauna that is traditionally used as a bioindicator in this sort of research. Therefore, the objective of this study was to investigate the edaphic entomofauna variation depending on glyphosate application in Roundup Ready soybeans. The experiment was carried out in Coimbra, MG during the 2007/2008 and 2008/2009 cropping seasons. The experimental design was a randomized block design with five replications. The treatments were: non-transgenic soybean with mechanical weeding of weeds; transgenic soybean with mechanical weeding of weeds; transgenic soybean with one glyphosate application and transgenic soybean with three glyphosate applications. The populations of the edaphic entomofauna were sampled during two crops. The insertion of the glyphosate tolerance gene did not affect the richness and the abundance of arthropods in the soil. The arthropod richness was reduced in treatments where glyphosate was applied one and three times. The glyphosate application in transgenic soybean reduced the density of the predatory mite Galumnidae (Acari); predator ants Neivamyrmex sp. (Hymenoptera: Formicidae) and Solenopsis sp. (Hymenoptera: Formicidae); and springtails Entomobryidae (Collembola), Hypogastrura sp. (Collembola: Hypogastruridae) and Onychiuridae (Collembola). Therefore, it is essential to follow the use recommendations of the herbicide glyphosate and adopt good agricultural practices that promote pesticide biodegradation, thereby contributing to the reduction of the toxicological potential of glyphosate on the edaphic entomofauna.

The use of cover crops can reduce or even eliminate the use of nitrogenous fertilizers, contributing to a more sustainable agriculture and ensuring the conservation of natural resources. Thus, the aim of this research was to evaluate the use of cover crops to improve the biomass yield of Serjania marginata plants. The experiment was carried out at the Federal University of Grande Dourados, in Dourados-MS, from December 2009 to February 2011. A split plot design was used in a randomized block design with four replications, being evaluated in plots three species of tropical legumes (Stizolobium aterrimum, Crotalaria spectabilis and Canavalia ensiformes, and one control plot (without cover crops), and in subplots the addition or not of nitrogen (N) (at 150 days after transplant (DAT)). Plants of S. marginata in each subplot were harvested at 240 and 350 DAT. S. aterrimum and C. ensiformes showed higher accumulation of fresh (average of 37.61t ha-1) and dry (average of 6.39t ha-1) biomass of shoot in flowering, compared with the C. spectabilis (21.92 and 4.63t ha-1, respectively). The contribution of cover crops as a likely source of N only was observed for S. aterrimum and C. ensiforme, which promoted an increase in chlorophyll index, leaf area, fresh and dry weight of leaves and stem of S. marginata plants, in absence of N. In leaves of S. marginata, only C. ensiformes contributed significantly to an increase in N levels, while an increase in K levels was observed with all cover crop treatments, when compared to control. Pre-cultivation with S. aterrimum and C. ensiformes provided an increase in P levels in leaves of S. marginata. Therefore, S. aterrimum and C. ensiformes were the most promising cover crops for growing of S. marginata, improving the biomass yield and probably the N economy.

Abstract. Susanto D, Amirta R. 2020. The application of NPK fertilizer boosts the nutrient uptake status and biomass production of Vernonia amygdalina. Nusantara Bioscience 12: 114-119. Vernonia amygdalina Delile is a medicinal plant introduced in Indonesia. This study aims to determine the nutrients absorption status and growth of V. amygdalina plants planted with a spacing of 1x1 m. The study used a complete randomized block design with NPK compound fertilizer treatment with five doses of fertilizer namely 0 g (without fertilizer) as a control, 40 g, 80 g, 120 g, and 140 g, three blocks each group consisted of 10 plants so that in total there were 150 plants. The results showed that NPK fertilizer increased growth and the biomass of V. amygdalina. The best growth of V. amygdalina plant was achieved in plants applied with 160g per plant NPK fertilizer in which the average of stem diameter and plant height were 6.69 ± 0.930 cm and 611.67 ± 12.71 cm, while the estimated biomass yield was 407 tons.ha-1. The most nutritional elements accumulated in plant biomass was the calcium (1279.49 kg.ha-1), followed by magnesium (1167.0642 kg.ha-1), phosphorus (536.64 kg.ha-1), potassium (419.71 kg.ha-1) and nitrogen (134.4 kg.ha-1). We propose that these base nutrients are highly necessary for the cultivation of V. amygdalina as biomass feedstock or medicine plant.

This study aims to determine the interaction of the composition of planting media and vermicompost dosage on the growth and yield of lettuce plants. This study is a pot experiment conducted by green house located on Jl. MT. Haryono, Dinoyo Subdistrict, Lowokwaru Subdistrict, Malang with a altitude of ± 550 meters above sea level, the average air temperature ranges from 20 °C - 28 °C, which starts in February to June 2019. The study uses experimental Randomized Block Design (RBD) arranged in factorial and consists of 2 factors. The first factor was the composition of the planting medium consisting of 2 levels, namely M1: Cocopit (55%), Biochar (15%), Sand (30%) and M2: Cocopit (55%), Biochar (30%), Sand (15%) The second factor is the vermicompost dose which consists of five types, namely V1: 50 gram / pot, V2: 100 gram / pot, V3: 150 gram / pot, V4: 200 gram / pot, and V5: 250 gram / pot. Based on the two factors, 10 treatments were obtained and each treatment was repeated 3 times with 5 plant samples per treatment, until a sample of 150 lettuce plants was obtained. The results showed that the composition of the planting medium gave growth and yield of different lettuce plants, where the composition of M1 planting media (cocopeat 55%, 15% biochar and 30% sand) gave the highest growth and yield of plants at the dosage application of 200-250 g / pot while the composition of M2 planting media (55% cocopeat, 30% biochar and 15% sand), gave the highest growth and yield at 150-250 g / pot vermicompost doses. This is caused by the influence of the composition of the planting medium and vermicompost dosage on the total fresh weight of plants, fresh weight of roots and fresh weight economically valuable curly lettuce M2V4 treatment (55% cocopeat growing media, 30% biochar and 15% sand, with vermicompost 200 gram / pot), M2V1 (planting media, 55% cocopeat, 15% biochar and 30% sand, with 50 gram vermicompost / pot dose) and M2V4 (planting media, 55% cocopeat, 30% biochar and 15% sand, with dosage 200 gram vermicompost / pot) with values of 66.06, 6.24 and 61.62 grams giving the highest results. Keywords: planting media composition, vermicompost dosage

ABSTRACT Jambu has spilanthol and phenolic compounds that are responsible for several medicinal properties. Besides improving nutrient absorption, arbuscular mycorrhizal fungi (AMF) can change secondary metabolites’ yield. Thus, the aim of the current study was to evaluate AMF inoculation and P influence on shoot dry biomass yield, macronutrient content (N, P, K, Ca and Mg), total phenol contents and spilanthol percentage in jambu plants. The experiment followed a randomized block design at 3x4 factorial arrangement, with two AMF (Rhizophagus clarus and Claroideoglomus etunicatum) and without AMF, at four P doses (0, 30, 60 and 90 mg/kg of soil), with four replicates. Plants inoculated with R. clarus and C. etunicatum, grown without phosphate fertilization, presented increase by 23 and 12 times, respectively, in comparison to plants without AMF. The relative spilanthol area in plants inoculated with R. clarus, without phosphate fertilization, reached 2.4%. Shoot dry biomass yield of jambu plants and the P, K, Ca and Mg contents were higher when plants were inoculated with R. clarus at the lowest P doses. The AMF also increased the contents of total phenols in plants fertilized with 60 mg kg-1. This P dose increased spilanthol concentration in jambu plants inoculated with C. etunicatum.

Maize is one of the main cereals produced worldwide and, in association withsoybean crop, can result in benefits to the production system. The objective of this study was to evaluate the biomass yield for silage and grain yield in maize crop, in the maizesoybean intercropping system. The study was conducted in the municipality of Dois Vizinhos - PR, Brazil, using a randomized block design, with nine treatments and four replicates. The treatments were composed of three maize hybrids grown in monoculture and in intercropping with two soybean cultivars (P1630+TMG7062, P1630+P95R51, P1630, LG6030+TMG7062, LG6030+P95R51, LG6030, P30F53+TMG7062, P30F53+P95R51 and P30F53). The data were subjected to analysis of variance and, when there was significance, Scott-Knott test was applied. Maize biomass yield for silage was approximately 4,000 kg ha-1 higher when the hybrids LG6030 and/or P30F53 were used. The cultivar TMG7062 stands out from P95R51 in terms of dry biomass yield for silage. The higher the percentage of soybean biomass added to the silage, the higher its crude protein content. However, crude protein yield per area was similar for the evaluated treatments. Some yield components (number of grains per row and thousand-grain weight) and grain yield of maize differ according to the hybrid used, but similarity is observed between intercropping and monoculture. There is evidence that the soybean cultivar TMG7062, intercropped with P1630, has the potential to reduce the grain yield of the cereal.

The soybean (Glycine max L.) plant is economically important for the food and animal feed industries due to its nutritional qualities. Soybean crops are highly productive and responsive to new technologies. The aim of this study was to assess the effect of Penergetic-P and Penergetic-K on the dry weight of shoot (DWS), dry weight of root (DWR), total dry weight (DWT), dry weight of nodules (DWN), number of nodules per plant (NNP), level of N in the shoot (NS), chlorophyll index, plant height and soybean yield. The experiment was conducted in a randomized block design with three replications. The means were compared by ANOVA and Duncan test (p ≤ 0.05). Differences among treatments for NNP were not significantly evident, but observed for DWN. The application of Penergetic-K in soil increased significantly the DWN in comparison with the application of only NPK and micronutrients. The DWR, DWS, DWT and the DWS/DWR ratio didn’t differ significantly among the treatments as well as the chlorophyll index and NS. The grain yield was significantly lower with the addition of NPK + micronutrients and significantly higher with the addition of Penergetic-K. The Penergetic-K promoted an increased soybean yield, up to 20% compared to the treatment with only NPK + micronutrients. It was concluded that the use of Penergetic benefits the soybean production and the soil quality.

Originating from backcrossing generations between wild and commercial sugarcane varieties, “energy cane” technology promises to revolutionize global energetic scenario, once full use of feedstock is allowed. Therefore, the aim of this study was to assess juice technological quality, lignocellulosic physical-chemical composition, and biomass yield of nine energy cane. The experiment had a randomized block design with five replications for each clone (treatment) (VX12-1659, VX12-1658, VX12-1356, VX12-1191, VX12-1022, VX12-0277, VX12-0201, VX12-0180, and VX12-0046) with five replicates. Following to tillage harvest, stalk samples were assessed for total soluble solids (ºBrix; % juice), sucrose (Pol; % juice), purity (Prt; % juice), reducing sugars (RS; % juice), theoretical sugars recoverable (TSR; kg t-1 stalks), Pol (% cane), RS (% cane), moisture (% cane), fibers (Fib; % cane), and dry biomass yield (DBY; t ha-1). The obtained data was subjected to the following statistical tests (p < 0.05): Shapiro–Wilk, Fisher, Tukey, and Pearson’s linear correlation. Findings revealed null hypothesis rejection, suggesting the clones significantly affected all assessed traits. The individuals VX12-1659, VX12-1658, VX12-1356, VX12-1191, VX12-1022, and VX12-0277 exhibited the highest °Brix (% juice), Pol (% juice), Prt (% juice), TSR, Pol (% cane), moisture (% cane), and Fib (% cane) values. In addition, the clones VX12-1659, VX12-1658, and VX12-1356 resulted in DBY averages higher than other individuals of the population. In fact, all clones showed Type II energy cane typical characteristics due to a low sucrose/fiber ratio. Thus, the energy cane clones are suitable for bioelectricity co-generation.
