Peanut ('Arachis hypogaea' L.) is one of the widely cultivated legume in tropical and subtropical regions. The aim of this study was to evaluate the agronomic characteristics of peanut (BR1) under ...different doses of dairy residue. The experiment was conducted as a randomized block design with three replicates. The treatments consisted of doses of milk residue: 0, 2.5, 5, 7.5, 10 m3 ha-1 and an additional control containing phosphors and potassium (PK) at dose of 15 and 50 kg ha-1. The following characteristics were determined in plants: leaf area, number of stems, shoot and root system length, dry weight of shoot and root system, number of pods and grain yield. The dose of 5 m3 ha-1 provided the highest agronomic characteristics. The grain yield was greater for the dose of 10 m3 ha-1. The dairy residue can be used as a source of fertilizer on peanut crop by meeting their nutritional requirements.
'Chorisia speciosa' A. St.-Hil., popularly known as paineira, barriguda, paineira-branca and paineira-rosa, belongs to the Bombacaceae family, being used to fill mattresses, pillows and cushions. The ...trees can be used in the construction of boats, boxes and mainly in the recovery of degraded areas. Among the most important tests of vigor, temperature is a factor that can directly interfere with germination and seedling growth. The accelerated aging might be emphasized as the most suitable to estimate seed vigor. The experiment was conducted in a laboratory of the Federal University of Alagoas/UFAL, aiming to determine the cardinal temperatures and to study the influence of accelerated aging on the germination and seed vigor of C. speciosa. The seeds were submitted to temperatures of 20 degrees C, 30 degrees C, 35 degrees C and 40 degrees C in paper roll substrate. For the accelerated aging test, temperatures of 41 and 45 degrees C were tested during the periods of 24, 48, 72 and 96 hours. The variables analyzed were: first germination count, germination, germination speed index (IVG), dry mass and seedling length. The results showed that temperature of 30 degrees C can be indicated as optimum for the germination of the species, since it provided the best values for the evaluated characteristics. Accelerated aging after 24 hours affected the physiological quality of C. speciosa seeds, promoting a reduction in viability and vigor.
Nowadays, the search for increase in the crop productivity with high organoleptic, physical and physiological quality of seeds remains one of the main objectives. Considering the importance of ...peanuts ('Arachis hypogaea' L.) for Brazilian agriculture and for the production of seeds, it is indispensable to use technological innovations aiming at the advancement of productivity and profitability for the seed producer. This study aimed to evaluate the yield and the components of peanut seed production of cultivar BR1, subjected to the foliar and seed application of Ca + B, Mo + P and Stimulate. The design was randomized blocks with the use of three products (Ca + B, Mo + P, Stimulate), two types of applications (via foliar and seed), the PK culture, and the absolute control, following a factorial scheme of (3 x 2) + 2. The doses of 2.0 mL/kg (Ca + B), 1.6 mL/kg (Mo + P), and 15 mL/kg (Stimulate) via seeds were indicated the best for the development of the peanut crop due to its profitability and efficiency. The application of Ca + B, Mo + P, and Stimulate via seeds is beneficial for the initial counting, emergence, emergence speed index, biological productivity, pod production, seed production and leaf area.
The variables related to the agro-industrial quality in sugarcane considered as main tools are being used by producers to choose the varieties to be planted. In general, cultivars that present a ...better industrial yield for the manufacture of sugar and alcohol have great importance promoting crop sustainability. In this research, the objective was to evaluate the industrial quality of four sugarcane varieties during plant-cane, first and second ratoon crops. The experimental design was a randomized block, with four treatments and five replications. The varieties studied were RB867515, RB92579, SP813250 and VAT90212. In first and second ratoon cycles, the industrial quality of the four varieties was evaluated by determining the fiber content, apparent sucrose (Pol), purity, soluble solids (Brix) and total recoverable sugars (TRS). The results showed that varieties RB867515, RB92579, SP813250 and VAT90212 were similar for agro-industrial quality. In first ratoon crop, only fiber was same between varieties. The RB867515 evidenced larger soluble solids and recoverable sugars. In second ratoon crop, the RB92579 evidenced larger apparent sucrose (Pol) and soluble solids (Brix) and total recoverable sugars (TRS).

The cactus pear is a culture of long cycle, which require the producer to find alternative source of income and can be a viable practice the consortium. The present study aimed to determine the appropriate dose of dairy waste to meet the nutritional needs of the peanut variety BR1 and determine the best population in peanut intercropped with forage cactus. The experiment was conducted under field conditions in the municipality of Garanhuns. In two stages, where the first was to determine the best dose of the milk residue able to meet the nutritional needs of peanuts. And a treatment fertilization (PK chemistry with) the doses of milk residue (0.0; 2.5; 5.0; 7.5 and 10.0 m3 ha-1) treatments were used. The experimental design was a randomized block design with three replications and six treatments, five doses of milk residue and a treatment containing P and K. The yield of groundnut was higher in the dose of 10 m3 ha-1. The second step was to determine the best population of peanut intercropped with being fertilized with the dose of milk residue determined in the previous step cactus pear. The treatments were T1 = Single Cultivation of cactus pear , T2 = Growing a single line of peanuts per plot, T3 = 2 Growing Single peanut lines per plot, T4 = 3 Growing Single peanut lines per plot, T5 = Palma 1 row intercropped with forage peanut, T6 = forage Palma intercropped with 2 rows of peanuts, T7 = forage Palma intercropped with 3 rows of peanuts. The characteristics evaluated were: shoot height, stem number, stem diameter, diameter of the main root diameter of pods, number of days for early flowering, number of gynophores not throw the soil, total biomass, number of pods, peanut production in the bark, productivity grain. In cactus pear were assessed the number of cladodes, length, width and diameter of the cladodes, plant height, yield and percentage of dry mass. The dose of 5.8 m3 ha-1 was efficient on the agronomic characteristics of peanut. The best production was obtained for the cultivated peanut with 225,000.00 plants per acre. The intercropping system does not impair the initial development of cactus in early do. The efficient use of land was efficient regardless of intercropping population.
A palma forrageira é uma cultura de ciclo longo, o que exigem do produtor encontrar outra fonte alternativa de renda e uma pratica viável pode ser o consórcio. O presente trabalho teve como objetivos determinar a dose de resíduo lácteo apropriada para suprir as necessidades nutricionais do amendoim,variedade BR1 e determinar a melhor população de amendoim a ser consorciado com palma forrageira. O experimento foi conduzido em condições de campo no município de Garanhuns. Em duas etapas, em que a primeira consistiu em determinar qual a melhor dose do resíduo lácteo capaz de suprir as necessidades nutricionais do amendoim. Foram utilizados doses de resíduo lácteo (0,0; 2,5; 5,0; 7,5; 10m3 ha-1) e uma testemunha adicional adubação (química com PK). O delineamento experimental foi em blocos ao acaso com três repetições e seis tratamentos, sendo cinco doses de resíduo lácteo e uma testemunha adicional contendo P e K. A produtividade de amendoim foi maior para a dose de 10 m3 ha-1. A segunda etapa consistiu em determinar qual a melhor população de amendoim a ser consorciada com a palma forrageira adubada com a dose de resíduo lácteo determinada na etapa anterior. Os tratamentos foram T1 = Cultivo solteiro da palma forrageira, T2 = Cultivo solteiro de uma linha de amendoim por parcela, T3 = Cultivo solteiro de 2 linhas de amendoim por parcela, T4 = Cultivo solteiro de 3 linhas de amendoim por parcela, T5 = Palma forrageira consorciada com 1 linha de amendoim, T6 = Palma forrageira consorciada com 2 linhas de amendoim, T7 = Palma forrageira consorciada com 3 linhas de amendoim. As características avaliadas foram: altura da parte aérea, número de haste, diâmetro do caule, diâmetro da raiz principal, diâmetro das vagens, número de dias para o início do florescimento, número de ginóforos que não atiram o solo, biomassa total, número de vagens, produtividade do amendoim na casca, Produtividade de grão. Na palma forrageira foram avaliados o número de cladódios, comprimento, largura e diâmetro dos cladódios, altura das plantas, produtividade e percentual de massa seca. A dose de 5,8 m3 ha-1 foi eficiente sobre as características agronômica do amendoim. A melhor produção foi obtida para o amendoim cultivado com 225.000 plantas por hectares.
