“…O déficit hídrico reduz frequentemente o peso das sementes (Pallas et al, 1979) e porcentagem de sementes "extra grandes" (Stansell et al, 1976) enquanto aumenta a porcentagem de sementes danificadas ou enrugadas (Boote et al, 1982). A irrigação não tem efeitos significativos nem consistentes sobre a concentração de óleo e proteínas das sementes (Boote et al, 1982).…”

RESUMO Com o objetivo de se definir a lâmina e o intervalo de irrigação para a cultura do amendoim cv. BR1, um experimento foi conduzido em Rodelas, Bahia, nos anos de 1994 e 1995. O solo na área experimental foi classificado como Regossol com mais de 89% de areia no perfil de 0 a 80cm. A demanda evaporativa do ar foi superior a 8mm por dia. Foram testados três lâminas totais de água, 300, 500 e 700mm e três intervalos de irrigação, 2, 4 e 6 dias, em delineamento de blocos ao acaso e esquema de análise fatorial 3x3, com irrigação por sulcos. Verificou-se que a produtividade de amendoim em grão e em casca foi significativamente afetada pelos dois fatores estudados, sendo o máximo, 3235kg.ha-1 de amendoim em casca, obtido com lâmina total de água de 700mm e intervalo de irrigação de 4 dias; o maior índice de colheita, de 37,4%, foi obtido no tratamento com 700mm de água e 6 dias de intervalo de irrigação, e o menor, 16,87%, no tratamento com 300mm de água e 4 dias de intervalo de irrigação, para a variável amendoim em grão.

“…The 1.83 m spaced laterals were spaced in alternate row middles. Research with drip irrigation has shown a water savings of about 25% (Sorensen et al, 2005) compared with recommendations by Irrigator Pro (Davidson et al, 2000) and Stansell et al (1976). Irrigation events were determined by Irrigator Pro, but irrigation depths were reduced by an average of 82% less than recommended by Irrigator Pro.…”

Surface drip irrigation laterals were spaced next to crop rows and in alternate row middles to document crop yield, market grade and gross/ partial economic returns compared with nonirrigated practices. A surface drip irrigation system was installed at two sites on a Faceville (Site 1) fine sandy loam and a Greenville (Site 2) fine sandy loam with 3 and 1% slope, respectively. The cultivar Georgia Green (GG) was planted in both single and twin-row configuration while the cultivar ViruGard (VG) was planted in only a twin-row configuration. Pod yield, farmer stock grade, and partial economic returns were determined for three growing seasons (2002 to 2004). Surface drip irrigated peanut had greater yield, market grade, and gross revenue compared with non-irrigated regimes. Subtracting the cost of the drip tubing showed that laterals spaced at 0.91 m are not cost effective ($-132/ha) while those spaced at 1.83 m returned an average $120/ha compared with the non-irrigated treatment. The cultivar GG had 425 kg/ha higher pod yield compared with VG (4035 kg/ha). Within irrigated lateral treatments, peanut planted in twin-row orientation had 1% higher market grade and lower OK compared with single row orientations. Pod yield and market grade was more stable at Site 2 compared with Site 1 which was probably due to slope and aspect characteristics associated with each site and not necessarily with soil series. The use of surface drip irrigation with peanut can be economically feasible if pod yield increases by at least 675 kg/ ha and growers place drip tubing in alternate row middles.

“…Decisions to apply pest management practices were determined by field scouting. Irrigation water was applied daily based on replacement of crop water use for peanut described by Stansell et al (1976) except when precipitation amounts exceeded estimated daily water use.…”

Selenium (Se) is identified as an antioxidant and anti-carcinogenic and increasing Se the peanut (Arachis hypogaea L.) plant could benefit human and animal health. In 2006, Se was applied to soil at two locations and four concentrations to determine Se concentration in the peanut plant. Selenium (Sodium Selenite) was applied at rates of 0.5, 1.0, 5.0 and 10 mg Se/kg soil. Prior to harvest, plant samples were collected, washed, partitioned, dried, and ground to pass through a 2 mm sieve and analyzed for Se. Composite soil samples were taken prior to peanut digging, air dried, and analyzed for Se. In general, the higher the concentration of Se applied to the soil the higher the concentration of Se in peanut leaf, stem, root, peg, kernel, and hull. There was no difference in Se concentration between sites for leaf, stem, root, or pegs. There was a difference of Se with hulls and kernels between sites possibly attributed to soil series. Pooled data over both sites showed the untreated areas had an average 0.495 mg Se/kg kernel. The 0.5Se and 1Se treatment had an average Se concentration of 3.97 mg Se/kg kernel which could decrease the quantity of peanuts a person would need to consume from 760 to 14 g/day to get the needed requirement of Se. The treatments 5Se and 10Se averaged 16.1 mg Se/kg kernel. Adding Se to the soil can increase Se in the peanut kernel and plant which could be beneficial to human and/or animal health. However, application of high grade Se to peanut land at 0.5 mg Se/kg would cost about $526/ha which may not be economical for the grower.
