The objective of this work was to determine the macronutrient doses that allow the highest phytomass yield and growth of basil plants. The experiment was carried out in the experimental area of ​​the Federal University of Recôncavo da Bahia, in Cruz das Almas, BA, in a greenhouse. The treatments were obtained according to the Baconian matrix statistical arrangement, in which one of the nutrients is supplied in variable amounts, while the others are kept at a referential level. Six nutrients (nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg) and sulfur (S)) were evaluated in three different doses, and two additional treatments, one with reference doses and another without nutrient addition, totaling 20 treatments that were arranged in a completely randomized design with five replications, totaling 100 experimental units. At 50 days after treatment distribution, the growth parameters were evaluated: Plant height, number of leaves, leaf dry mass, stem, root and leaf area. It was observed that the highest leaf dry mass accumulation was estimated with the dose of 250 mg dm³ of N giving an average of 8.01g per plant, being significantly higher when compared to all other tested elements, this parameter is extremely relevant because the leaves are characterized as the main product of this species. Phosphorus doses allowed significant results in height and leaf area, whereas K favored higher leaf emission. Positive responses were verified for nutrients Ca, Mg and S in all parameters tested at levels above those tested as reference.

O meloeiro tem grande importância econômica para o Nordeste brasileiro. Entretanto, em seu cultivo utiliza-se insumos que podem prejudicar o ambiente; como, os fertilizantes nitrogenados. Objetivou-se avaliar a emissão de N2O em cultivo de meloeiro amarelo ‘Goldex’. O experimento foi instalado em delineamento inteiramente casualizado, com cinco repetições. Os tratamentos foram: 0 (controle), 1,0; 1,5 e 2 vezes a quantidade de nitrogênio recomendada para cada estádio. Foi analisado o fluxo de N2O, área foliar, número de folhas, massa seca da parte aérea, massa seca dos frutos, massa seca da parte radicular, nitrogênio total do solo, das plantas e N (NH4+ e NO3-) do solo. O fluxo de N2O teve comportamento temporal irregular durante a fase de plântulas e crescente na floração. Os tratamentos afetaram significativamente a área foliar, número de folhas, massa seca da parte aérea, massa seca da parte radicular, nitrogênio da parte aérea e parte radicular das plantas e do solo. A aplicação de nitrogênio, em dosagens superiores à recomendada, não aumentou a produção do meloeiro. E o cálculo do fator de emissão mostrou que a emissão do N2O não atingiu valores prejudiciais ao ambiente.Palavras-chave: fator de emissão, efeito estufa e nitrogênio. NITROUS OXIDE EMISSION ASSOCIATED WITH UREA USE THE YELLOW MELON CROP ABSTRACT: The melon has great economic importance for the Brazilian Northeast. However, in its cultivation uses inputs that can harm the environment; Such as nitrogen fertilizers. The objective of this study was to evaluate the emission of N2O in yellow 'Goldex' cultivar. The experiment was installed in a completely randomized design with five replications. The treatments were: 0 (control), 1.0; 1.5 and 2 times the amount of nitrogen recommended for each stage. N2O flux, leaf area, leaf number, shoot dry mass, fruit dry mass, dry mass of the root portion, total soil nitrogen, of the plants and N (NH4 + and NO3 -) of the soil were analyzed.

Weeds compete with plants for water, light, nutrients and space. In sugarcane, planting pre-sprouted sugarcane seedlings (PSS) may mean a change in weed interference and management. The aim of this study was to generate information on the interference of Cyperus rotundus L. in PSS. Two experiments were carried out in a completely randomized design, one with cultivar RB985476, with seven densities of C. rotundus (0, 17, 35, 70, 140, 280 and 560 plants m-2), and the second with cultivar IACSP95-5000, with four densities of C. rotundus (0, 70, 140 and 280 plants m-2). For this weed, a 2x6 factorial design was used for the experiment with RB985476 and a 2x3 design was used for IACSP95-5000, the first factor being absence and presence of the crop, and the second factor the densities of the species. Biometric evaluations of height, diameter, number of tillers and leaves, leaf area and dry mass were carried out. The PSS had a reduction in height, number of leaves and leaf area in the main till at 60 d after planting (DAP) in RB985476. For the IACSP95-5000 cultivar, there was no reduction in the analyzed variables. The average dry mass per plant of C. rotundus decreased as the density of the species increased in the absence of PSS.

Red spinach (Amaranthus gangeticus) is one of the most popular vegetables because of its high nutritional value and easy cultivation. Efforts to increase the production of red spinach are to fertilize to meet the needs of both macro and micronutrients. This study aimed to determine the effect of ZA fertilizer dose on the growth and yield of red spinach. The environmental design used was a non-factorial, completely randomized design with four replications. The factors tested were the dose of ZA fertilizer which consisted of 6 levels, namely: without ZA fertilizer (D0); 0.4 gr/polybag (D1); 0.8 gr/polybag (D2); 1.2 gr/polybag (D3); 1.6 gr/polybag (D4); 2 gr/polybag (D5). The data obtained were analyzed using analysis of variance, and if the results were significantly different, the BNT test was continued at a 5% level. The growth and yield of red spinach showed significant differences due to the ZA fertilizer dose treatment. The ZA fertilizer dose treatment of 1.2 g/polybag (D3) resulted in the highest plant height, the number of leaves, and leaf area of red spinach at 14, 21, and 28 days after planting. The ZA fertilizer dose treatment of 1.2 g/polybag (D3) resulted in the highest wet and dry weight plants of 49.15 and 4.38 grams, respectively. The ZA 1.2 gr/polybag dose is the ideal dose to increase the productivity of red spinach.Bayam merah (Amaranthus gangeticus) termasuk sayuran penting yang disukai masyarakat karena bernilai gizi tinggi dan mudah pembudidayaannya.

The application of Trichoderma fungus can be used to obtain seedlings of higher quality for plantations. The objective of this study was to evaluate the effects of Trichoderma isolates on the germination and initial growth of açaí seedlings. Two trials were set up. In the laboratory, the seeds were inoculated in suspensions prepared with each of the isolates for 24 h, and they were arranged in trays containing filter paper in a completely randomized design with five replicates containing 50 seeds each. For the control, the seeds were submerged only in water. Part of the seedlings resulting from seeds treated and not treated with Trichoderma were transferred to bags containing forest soil and were submitted to seven modes of application of Trichoderma and kept in a nursery. The speed of germination and hypocotyl were not influenced by the biological treatment. The application of the different Trichoderma isolates positively influenced the height, collar diameter, number of leaves, root size, leaf area and root, and aerial part dry mass of the açaí seedlings. The application of the Trichoderma isolate TAM01 on the preplanting substrate and biweekly applications on the postplanting substrate was the combination that most positively influenced the development of açai seedlings.

[EFFECT OF CONCENTRATION AND APPLICATION TIME OF ORGANIC FERTILIZER LIQUID BANANA PEELS ON GROWTH AND YIELD OF JAVA TEA (Orthosiphon aristatus)]. Java tea are medicinal plants that have many health benefits but java tea production is very low. Efforts are made to increase the growth and yield of java tea, namely the use of liquid organic fertilizer (LOF) banana peels. This study aims to obtain concentration, application time of LOF banana peels, and interactions between the two that produce high growth and yield of java tea. The study was conducted from November 2018 to February 2019 in the city of Bengkulu. The experiments were arranged based on a completely randomized design factorial pattern. The first factor is the LOF concentration of banana peels 25 mL/L, 50 mL/L, 75 mL/L, and 100 mL/L. The second factor is the time of LOF application which consists of 1 week application, 2 weeks application, and 3 weeks application. The results showed that independently giving concentration and application time and interaction did not significantly influence the variable thickness of leaves, total leaf area, shoot length, number of leaves, fresh plant weight, root length, and dry plant weight.

Objective: The objective of this study was to evaluate the response of different concentrations of a fungal consortium on the growth and yield of Cenchrus purpureus ecotypes under storm conditions.Design/Methodology/Approach: An experiment was established under a completely randomized design with a 9X2X4 factorial arrangement. The factors were 9 ecotypes of Cenchrus purpureus, two seasons of the year (Summer-Fall and Winter-Spring), and four levels of mycorrhizal consortium. The variables evaluated were: number of buds, number of leaves, height of the bud, leaf length, total biomass, and leaf-stalk ratio.Results: The response of the ecotypes had a differential effect on the variables NB, LLL, TB and L/SR, while the season affected the variables LN, PH, LLL, MLL, SLL, TB and L/SR. Low inoculation levels increased the variables NB, PH, LLL, MLL and TB.Study Limitations/Implications: The evaluated factors indicate that the level of inoculant and the season determine the growth and yield of Cenchrus purpureus.Findings/Conclusions: The mycorrhizal consortium dose and season of the year mainly determined the growth and yield of C. purpureus. Ecotypes respond differently to changes in the season and in mycorrhizal consortium dose. The evaluated factors indicate that the mycorrhiza dose and the season of the year determine the growth and yield of C.purpureus. Two growth strategies of the ecotypes are visualized: 1) many buds, with few small leaves and 2) few buds with many large leaves

Fruit waste can be a good source of liquid organic fertilizer (LOF) because it contains macro and micronutrients needed by plants. This study aims to determine the type and concentration of LOF for the growth and yield of leek (Allium fistulosum, L.). This research was conducted from June to August 2019, in Pematang Gubernur, Muara Bangkahulu, Bengkulu City, Indonesia. Treatment consist of types of Liquid Organic Fertilizer (LOF) which were cow manure (CM) and guava waste (GW) at concentrations of 25%, 50%, and 75%. Experimental treatment included; without LOF, CM LOF (25%), CM LOF (50%), CM LOF (75%), GW LOF (25%), GW LOF (50%), GW LOF (75%), CM LOF + GW LOF (25%), CM LOF + GW LOF (50%) and CM LOF + GW LOF (75%). The study used a completely randomized design (CRD), one factor, repeated five times. Differences in LOF concentration and source significantly affected the number of leaves and tiller diameter. Nonetheless, it did not affect the number of tillers, plant height, and fresh weight. Cow manure liquid organic fertilizer at a 50 % concentration raised the number of leaves by 35 %, whereas guava waste increased the leaves numbers by 25%. With the application of guava waste liquid organic fertilizer at a concentration of 75%, so the number of tillers increased by 23%.

The objective this work was to investigate the competitive ability between resistant and susceptible ryegrass biotypes and of these with soybean crop. Four experiments were carried under greenhouse, in a completely randomized design with four replications, in 2011 and 2012. Treatments were arranged in additive series and replacement series assay. In each series, the proportions among ryegrass resistant and susceptible plants related to soybean were: 100:0, 75:25, 50:50, 25:75 e 0:100. Leaf area and shoot dry mass were evaluated. Competitiveness statistical analysis consisted in applying diagrams to the replacement series and alternative interpretations of the competitiveness indexes. The soybean crop had equivalent competitiveness to the susceptible ryegrass biotype and inferior to the resistant biotype, while the biotypes, both susceptible and resistant to glyphosate, present equivalent competitive ability. In general, the intraspecific competition is more harmful to ryegrass when in competition with soybean, while interspecific competition is predominant for culture.
