<p>Esta pesquisa buscou conhecer características alelopáticas e de fertilidade de um solo oriundo de povoamento de <em>Luetzelburgia auriculata </em>(Allemão) Ducke), através da avaliação do crescimento de plantas de alface. Inicialmente, realizou-se a coleta do solo sob o povoamento da <em>L. auriculata</em> (SPL) e de uma área externa a esse povoamento (SAE), na Fazenda Cachoeira de São Porfírio, em Várzea-PB, e encaminhou-se para o Centro de Saúde e Tecnologia Rural da Universidade Federal de Campina Grande, Campus de Patos. Em delineamento inteiramente casualizado, aplicaram-se cinco tratamentos com cinco repetições, colocando-se três sementes de alface por vaso contendo os seguintes tratamentos: T1=100%SAE; T2=100%SPL; T3=75%SPL; T4=50%SPL e T5=25%SPL. Aos 63 dias da semeadura, realizou-se a colheita e mensuraram-se as variáveis: comprimento da parte aérea, da raiz, peso da massa fresca da parte aérea, área foliar e número de folhas de cada indivíduo e a análise química dos substratos. Aplicou-se a ANOVA e o teste de Tukey a 5% de probabilidade. O solo do povoamento da <em>L. auriculata</em> (SPL) apresentou uma maior quantidade de nutrientes em relação ao solo da área externa ao povoamento (SAE) e influenciou positivamente no crescimento das plantas de alface. No entanto, em apenas três dos cinco tratamentos aplicados (T1, T2 e T3), a alface se desenvolveu. Em T1, T2 e T3 as variáveis analisadas diferiram estatisticamente em função da origem dos solos utilizados e da proporção do esterco bovino. O solo oriundo do povoamento de <em>L. auriculata</em> não apresentou efeito alelopático sobre os parâmetros de crescimento da alface.</p><p align="center"><strong><em>Seedling growth lettuce (</em></strong><em>Lactuca sativa<strong> L.) in soil arising out of a settlement </strong>Luetzelburgia auriculata<strong> (Allemão) Ducke</strong></em></p><p><strong>Abstract</strong><strong>: </strong>This research aimed to know allelopathic characteristics and fertility of the soil arising out settlement <em>Luetzelburgia auriculata</em> (Allemão) Ducke by assessing the growth of lettuce plants.

<p>A agricultura orgânica se destaca como modo de produção que consiste em um sistema sustentável. Um dos desafios desse método de cultivo é a produção de alimentos com qualidade em quantidades suficientes sem comprometer o meio ambiente. Objetivou-se analisar o efeito de substratos orgânicos na germinação e crescimento inicial de alface. O experimento foi conduzido em delineamento inteiramente casualizado com quatro tratamentos (substratos) e duas repetições. Foram testados os substratos: composto de Sibipiruna, substrato comercial, composto de Sibipiruna com chorume e substrato comercial com chorume. O chorume foi obtido exclusivamente da decomposição de vegetais. Foi avaliado o efeito dos substratos pelo percentual de germinação, massa fresca, massa seca e comprimento da radícula. Pôde-se considerar que houve diferença significativa entre os tratamentos. As sementes, quando germinadas em substrato de Sibipiruna com chorume, apresentaram maior massa seca e comprimento de radícula. Com relação à massa fresca, os valores obtidos foram maiores quando o chorume foi adicionado a ambos os substratos. O chorume obtido da decomposição de vegetais aumentou a germinação e o crescimento inicial das plântulas.</p><p align="center"><strong><em>Emergence and growth of lettuce (</em></strong><em>Lactuca sativa<strong> </strong>L.<strong>) submitted to organic substrates</strong></em></p><pre><strong>Abstract: </strong>Organic agriculture stands out as a mode of production consisting of a sustainable system. One of the challenges of this method of cultivation is the production of sufficient quality food in sufficient quantities without compromising the environment. The objective of this study was to analyze the effect of organic substrates on germination and initial lettuce growth. The experiment was conducted in a completely randomized design with four treatments (substrates) and two replicates. The substrates were tested: Sibipiruna compound, commercial substrate, Sibipiruna compound with slurry and commercial slurry substrate. The manure was obtained exclusively from the decomposition of vegetables. The effect of the substrates was evaluated by percentage of germination, fresh mass, dry mass and radicular length. It was possible to consider that there was a significant difference between treatments. The seeds, when germinated in substrate of Sibipiruna with slurry, presented higher dry mass and radicle length. Regarding the fresh mass, the values obtained were higher when the slurry was added to both substrates. The slurry obtained from the decomposition of plants increased the germination and the initial growth of the seedlings.</pre>

Os compostos alelopáticos podem afetar o crescimento e inibir a germinação das espécies. O objetivo deste trabalho foi analisar a fitoquímica e o efeito alelopático do extrato das folhas de Schinus terebinthifolius Raddi na germinação e crescimento de plântulas de Lactuca sativa L. e, posteriormente, aplicar a metodologia em eucalipto vermelho (Eucalyptus camaldulensis). Os compostos químicos foram determinados em extrato alcoólico das folhas, comparados e contrastados observando a alteração de cor. As sementes de alface e eucalipto vermelho foram distribuídas em gerbox contendo papel filtro como substrato, umedecido com 7 mL do extrato aquoso das folhas frescas, nas seguintes concen trações: (0; 12,5; 25; 50; 75 e 100%). Para todas as análises e experimentos foram utilizados três repetições. Os gerbox foram distribuídos em um delineamento inteiramente casualizado, mantidos em câmara de germinação com temperatura de 20 °C para alface e 28°C para eucalipto e fotoperíodo de 12 horas. Durante o segundo e quinto dia foram realizadas contagens das sementes germinadas de alface. O período de avaliação do experimento foi de cinco dias para alface e 12 dias para eucalipto. Ao final, foram determinadas as porcentagens de germinação, comprimento da raiz e de parte aérea das plântulas. Os resultados demonstraram interferência negativa na germinação e crescimento de alface e eucalipto em função do aumento da concentração do extrato. Entre os aleloquímicos predominantes estão os compostos fenólicos e derivados, com destaque aos flavonoides, terpenos e heterosídeos cardioativos o que pode estar relacionados ao efeito alelopático negativo da aroeira. O uso da aroeira associado ao eucalipto deve ser feito com um manejo adequado.   Palavras-chave: Alface. Aleloquímicos. Anacardiaceae. Eucalipto. Efeito Alelopático.   Abstract Allelopathic compounds can affect growth and inhibit species germination. The objective of this work was to analyze the phytochemistry and the allelopathic effect of  extract of  Schinus terebinthifolius Raddi leaves on the  Lactuca sativa L. seedlings germination and growth and later apply the methodology in red eucalyptus (Eucalyptus camaldulensis). The chemical compounds were determined in the leaves alcoholic extract, compared and contrasted observing the color change. The lettuce and red eucalyptus seeds were distributed in a gearbox containing filter paper as a substrate, moistened with 7 mL of the fresh leaves aqueous extract in the following concentrations: (0; 12.5; 25; 50; 75 and 100%). For all analyzes and experiments, three repetitions were used. The gearbox was distributed in a completely randomized design, maintained in a germination chamber with a temperature of 20 °C for lettuce and 28 °C for eucalyptus and a photoperiod of 12 hours. Germinated lettuce seeds were counted during the second and fifth days. The experiment evaluation period was five days for lettuce and 12 days for eucalyptus. At the end, the germination percentages, root length and the seedlings aerial part were determined. The results showed negative interference in the germination and growth of lettuce and eucalyptus due to the extract increased concentration. The most frequent allelochemicals were flavonoids, terpenes, tannins, anthocyanins and heterosides, which are probably related to the negative allelopathic effect. The use of  aroeira associated with eucalyptus must be done with proper management.   Keywords: Lettuce, Allelochemicals Anacardiaceae. Eucalyptus. Allelopathic Effect.

Biofertilizers may be a better eco-friendly option to maintain soil fertility. The study was conducted to investigate the effect of Azotobacter and Trichoderma on the vegetative growth of maize (Zea mays L.) plants. The experiment was carried out in medium sized pots, at IAAS, Lamjung (Feb 2017 - May 2017) in completely randomized design (CRD), consisting eight treatments and three replications. Treatments were namely T1 (control), T2 (Azotobacter), T3 (Trichoderma), T4 (Azotobacter + Trichoderma), T5 (NPK), T6 (Azotobacter + Trichoderma + FYM), T7 (Azotobacter + Trichoderma + FYM + NPK), T8 (FYM). Azotobacter showed a positive increase in plant height, stem girth, dry shoot weight, root length and width, and root weight while Trichoderma displayed either negative or minimal impact. Effect of FYM was lower than Azotobacter but considerably higher than Trichoderma. Trichoderma seriously inhibited the expression of Azotobacter when used together. Trichoderma even suppressed the outcome (except shoot weight) of FYM when used together. Root length was the longest in Azotobacter inoculation. The highest number of leaves was in T7 followed by Azotobacter (T2) and NPK (T5). Unlike leaf width, Azotobacter showed a negligible increase in leaves length while Trichoderma wherever present showed the negative impact. Minimum chlorophyll content was found in Azotobacter or Trichoderma after 73 days. Azotobacter treatment showed early tasseling than Trichoderma. The association of Azotobacter and Trichoderma increased the biomass. Azotobacter has significant effects on growth parameters of maize and can supplement chemical fertilizer, while Trichoderma was found to inhibit most of the growth parameters.

Lettuce Growth

As the human population rises, the demand for high nutritional foods, such as green vegetables, also increases. However, agricultural land, especially in urban areas, is increasingly narrowing. Hydroponics can be one of the solutions to answer this problem. In addition to complete nutrition, hydroponic plants also require appropriate media for root attachments, water absorption, and aeration. However, no studies have compared the growth of hydroponic plants using rockwool and sponge as affordable growing media. Therefore, this study aimed to determine the effect of local rockwool, imported rockwool, and sponge as growing media on the growth of spinach (Amaranthus sp.) and green lettuce (Lactuca sativa) using Deep Flow Technique (DFT). This study used a Completely Randomized Design with three treatment groups, i.e., three different growing media, for spinach and lettuce. At the harvest period, the number of leaves on each plant was counted, the crown fresh-weight was balanced, and the chlorophyll content was determined. Plant height was also measured for spinach. The results showed no significant differences in all observed parameters except for the crown fresh-weight of the lettuce. The crown fresh-weight of the lettuce grown on sponge media was found to be the lowest significantly (81.47 ± 9.50 g) among all treatment groups. Other hydroponic growing media’s influences can be investigated for further research, with additional growth parameters such as crown dry-weight, root fresh- and dry-weight, as well as the determination of plant phytochemical contents. Moreover, the composition of nutrients can also be further examined to reveal the type of growing media and nutritional formulations that are most optimum for hydroponic spinach and lettuce growth.

This study was to evaluate the growth response of Archachatina marginata as influenced by four natural diets: Pawpaw (Carica papaya) cocoyam (Colocasia esculenta), cocoyam (Xanthosoma sagittifolium), and cassava (Manihot esculenta) leaves and growers mash (a compounded ration). One hundred and twenty (120) grower snails (Archachatina marginata) were purchased from a farm in Ibadan, Oyo State. Data were collected on the growth parameters (weight, length and circumference of shell of the snails arranged in a Completely Randomized Design and replicated three (3) times. The results showed that pawpaw (Carica papaya) recorded the highest mean in all the parameters measured and throughout the duration of the experiment. Cocoyam (Colocasia esculenta) leaf had a better mean than the Cassava (Manihot esculenta) leaves in terms of weight gained whereas the reverse is the case in terms of length and circumference of shell. Pawpaw (Carica papaya) is therefore, recommended to both local and small scale farmers in Abia State and in Nigeria for feeding their snails and cocoyam (Colocasia esculenta) leaves and growers mash as an alternate feed.

ABSTRACT The study aimed to evaluate the initial development, as well as, the chemical characteristics of lettuce plants grown in substrate with high concentrations of bioagent (trichoderma). A completely randomized design with four replicates was used. The treatments, applied to a substrate composed of a blend of vermicompost and commercial substrate, were established by the following doses of the commercial product ICB Nutrissolo Trichoderma: T1) 0.0; T2) 1.0; T3) 2.0; T4) 4.0; T5) 8.0 and T6) 16.0x1011 conidia kg-1 of product. After inoculation, the substrate was placed in trays, where 50 lettuce seeds were sown on each replication. Plants were thinned after emergency stabilization, maintaining ten seedlings per tray. At 28 days after sowing, the characteristics percentage and emergence speed index, leaf area, fresh and dry leaf biomass, volume, length and surface area of the root were evaluated. We also determined the chemical characteristics of the leaves. The percentage of seed germination and the emergence speed index were lower at doses higher than 4.0x1011 conidia kg-1 of the biological product. All the studied doses influenced negatively in shoot and root development of the plants. The percentage of nutrients in the leaves was higher in treatments with ICB.

This study aimed to evaluate the allelopathic effect of various concentrations of an aqueous extract of eucalyptus leaves on Urochloa decumbens and Panicum maximum seeds. The extract was prepared from Eucalyptus urograndis leaves that were milled and mixed with distilled water in a 1:9 milled leaves: water ratio to obtain an extract with a defined concentration of 100%. In addition, dilutions of 50%, 25% and 12.5% were prepared, and a 0% dilution was used as a control. The experiment followed a completely randomized design, with four replicates, each of 50 seeds of U. decumbens and 50 seeds of P. maximum, arranged on filter paper moistened with each concentration of extract in a Gerbox plastic box. The results demonstrated the allelopathic potential of E. urograndis aqueous extracts applied to the seeds of U. decumbens and P. maximum. The 50% and 100% concentrations of leaf extract most strongly inhibited the germination, vigor and seedling growth of U. decumbens and P. maximum. The germination speed index and the root length were the characteristics that were most affected by the potentially allelopathic substances contained in the eucalyptus extracts at all concentrations.

Twenty five weaned male rabbits of mixed breeds were used to investigate the effect of replacing bone ash with fresh water snail shell ash on the performance of weaned rabbits. The experiment was conducted at the Teaching and Research Farm, University of Agriculture, Makurdi, Benue State, Nigeria for a period of 12 weeks. The rabbits were randomly assigned to the five dietary treatments and replicated five times giving a total of one rabbit per replicate in a completely randomized design (CRD). Rabbits were raised intensively in hutches of about 4ft × 4ft. Five experimental diets tagged T1 to T5 were formulated such that fresh water snail shell ash replaced bone ash at 0%, 25%, 50%, 75% and 100%. Feed and water were served ad libitum. Bio sanitary and bio security measures were strictly adhered. The study showed that the growth parameters were not affected (P=.05) by the dietary treatments. This study had shown that fresh water snail shell ash can serve as a substitute for bone ash in weaned rabbits diet up to 100% without compromising their performances.

ABSTRACT: The inclusion of sesame oil associated with soybean, linseed and freshwater fish residue oil in the diets fed to Lambaris Astyanax altiparanaewas evaluated by the growth performance parameters, body composition and possible physiological changes (GARUTTI & BRISTSKI, 2000). The experiment was a completely randomized design in two factorial parameters tested: three oil types (soy oil (SO), linseed oil (LO) and freshwater fish residue oil (FRO)), combined or not with sesame oil (SEO), totalizing six treatments and four replications 24 cages, capacity of 0.70m3 (density of 251 fish m-3). The fish (mean weight 2.35g±0.62g and mean length 5.25cm±0.68cm) were fed with the experimental diets twice a day. After 75 days, the following parameters were determined: body chemical composition and fatty acid profile, glycemia, liver (LG) and muscle glycogen (MG) levels, and lipid peroxidation (TBARS). Fish fed with diets containing SEO had higher desaturation index values of LNA while those fed with SEO combined with LO displayed reduced hepatic lipid oxidation. Inclusion of SEO improved the fatty acid profile and stability, without causing problems related to fish performance and health.
