Germinative potential of Ocimum basilicum L. seeds in commercial substrate and soil conditioner

In the production process Ocimum basilicum seeds, the substrate selection is an important characterist in qualitative terms, as way to obtain a great culture development, in addition to reducing the production costs. The objective of this reserach was to analyze the effect of the substrate based on tanned bovine manure, at diferent concentration, on the germination of O. basilicum seeds. The research was conducted under greenhouse conditions, ans composed by six treatments, related with the comercial substrate Carolina Soil® and also by tanned bovine manure, analyzed alone, but also in misture with diferente concentrations. For each treatment, six replicates were carried out, directed into plastic polyethylene trays, and each replicate was characterized by 10 cells from the tray. After filling the cells with each treatments, sowing was carried out, and after second day of planting, evaluation were carried out regarding the average number of germination seeds, germination speed index (GSI) and the average germination time (AGT). The best results were related to the treatments based on commercial substrate and also commercial substrate (80%) + tanned bovine manure (20%), with average seed germination above 78.33%, and addition to higher GSI, with average above 1.21, and lower AGT, whose average was below 6.78 days, showing the positive effect of the addition of up to 20% tanned bovine manure in the commercial substrate Carolina Soil®, regarding the germination of O. basilicum seeds.In the production process Ocimum basilicum seeds, the substrate selection is an important characteristic in qualitative terms, as way to obtain a great culture development, in addition to reducing the production costs. The objective of this research was to analyze different concentrations of commercial substrate associated with a soil conditioner, based on tanned bovine manure, in the germination of O. basilicum seeds. The research was conducted under greenhouse conditions, in a completely randomized experimental design, and composed by six treatments [commercial substrate (100%) (T1); commercial substrate (80%) + tanned bovine manure (20%) (T2); commercial substrate (60%) + tanned bovine manure (40%) (T3); commercial substrate (40%) + tanned bovine manure (60%) (T4); commercial substrate (20%) + tanned bovine manure (80%) (T5); and tanned bovine manure (100%) (T6)], and six replicates, and each replicate was characterized by 10 cells from the tray. The seeds were placed into plastic polyethylene trays, under steel countertops. After filling the cells with each treatment, sowing was carried out, and after second day of planting, evaluation was carried out regarding the average number of germination seeds, germination speed index (GSI) and the average germination time (AGT). The best results were related to the treatments based on commercial substrate and also commercial substrate (80%) + tanned bovine manure (20%), with average seed germination above 78.33%, and addition to higher GSI, with average above 1.21, and lower AGT, whose average was below 6.78 days, showing the positive effect of the addition of up to 20% tanned bovine manure in the commercial substrate Carolina Soil®, regarding the germination of O. basilicum seeds

Efeito de substratos orgânicos no desenvolvimento vegetativo de brachiaria brizantha cv. Marandu

Agricultural activity has great national relevance, mainly due to extensive management, based on the use of forages, for which they still need to be better studied from the nutritional point of view, mainly about the use of organic substrates. The objective of this research was to analyze the effect of organic substrates on development Brachiaria brizantha cv. Marandu, in greenhouse conditions. The experiment was conducted at School Farm of University of Araraquara (UNIARA), with the treatments related to standard soil (100%) (T1), in addition to other treatments with different concentrations of organic substrates: Standart soil (80%) + Genesolo® (20%) (T2); Standart soil (80%) + Tanned cattle manure (20%) (T3); Standard soil (80%) + Tanned chicken manure (20%) (T4); and Standard soil (80%) + Organic soil (10%) (T5). For each treatment were conducted five replicates, each corresponding to a 15L polyethylene vessel. Seedling transplantation was performed between 15-20 days after emergence and, as parameters of analysis, three cuts were made, at 10-cm in height from the soil surface, conducted every 60 days after seedling transplantation, aiming to collect material to evaluate the average weight of fresh and dry matter of the aerial part of plants. The organic substrates significantly improved the development of B. brizantha cv. Marandu, with emphasis on the use of tanned chicken manure and tanned cattle manure, especially when related up to 120 days after seedling transplantation.A atividade agropecuária apresenta grande relevância nacional, principalmente frente ao manejo extensivo, balizado no uso de forrageiras, pelas quais ainda necessitam ser melhor estudadas do ponto de vista nutricional, principalmente no que condiz ao emprego de substratos orgânicos. O objetivo da pesquisa foi analisar o efeito de substratos orgânicos no desenvolvimento de Brachiaria brizantha cv. Marandu, sob condições de casa-de-vegetação. O experimento foi conduzido nas dependências da Fazenda Escola da Universidade de Araraquara (UNIARA), com os tratamentos relacionados ao Solo Padrão (100%) (T1), além deste adicionado de diferentes concentrações de substratos orgânicos: Solo padrão (80%) + Genesolo® (20%) (T2); Solo padrão (80%) + Esterco Bovino curtido (20%) (T3); Solo padrão (80%) + Cama de Frango curtida (20%) (T4); e Solo padrão (80%) + Terra Orgânica (10%) (T5). Para cada tratamento foram conduzidas cinco repetições, cada qual correspondente a um vaso de polietileno de 15L. O transplante de plântulas foi realizado entre 15-20 dias da emergência e, como parâmetros de análise, foram realizados três cortes, a 10 cm de altura da superfície do solo, conduzidos a cada 60 dias após transplantio, visando a coleta de material para avaliação do peso médio de matéria fresca e seca da parte aérea. Os substratos orgânicos melhoraram significativamente o desenvolvimento de plantas de B. brizantha cv. Marandu, com destaque ao uso da cama de frango e também do esterco bovino, principalmente quando relacionados até 120 dias do transplantio
