“…According to Nakagawa and Rosolem (2011), peanut sensitivity to water stress is lower in the period from seedling emergence to early formation of the floral organs and expressively increases during the flowering and fruiting stages, which occurred in the treatments with deficit irrigation for both sowing dates. These results also corroborate those observed by Barbieri et al (2017), who found differences in the yields of the cultivars IAC Tatu (erect) and Runner IAC 886 (dwarf) under water replacement levels.…”

Water deficit is considered the most critical environmental factor for peanut production in Brazil, as it constitutes one of the major constraints to the expansion of its cultivation in the suitable crop zones of the country. Determining crop water demand is fundamental to increasing yield with lower water consumption. The present study aimed to evaluate the effects of full and deficit irrigation levels (L1 = 8%, L2 = 27%, L3 = 63%, L4 = 94% and L5 = 100% replenishment of crop evapotranspiration) on the development, growth and yield of peanut crop sown in two times, February and March. Treatments were distributed in a split-plot randomized complete block design, with four replicates, using a line-source sprinkler system. Irrigation depths from 65 to 314 mm were applied with the levels L1 to L5 during the first and second cropping cycles. Full irrigation with sowing in March was more advantageous due to yield increase of up to 30% compared to sowing in February, but crop cycle was 25 days longer. Water stress caused by deficit irrigation reduced plant height, seed mass and pod yield, while full irrigation (L5) led to yields from 4,141 to 5,102 kg ha-1 for February and March, approximately three times higher than those obtained with the lowest irrigation level (L1). Highlights Peanut has great importance in the food and industry of several countries. The results of this research apply to regions that require irrigation, which is of about 70% of the areas of the globe with this legume. This paper contributes with information that emphasizes the possibility of cultivation in the drought season, aiming at the expansion of the crop and the production of quality seeds using irrigation.

“…Kandil et al (2007) founded that the nitrogen level was increased stems, leaves number, total pods, and pod dry weight in per plant. Barbieri et al (2017) stated that the treatments of ET0 as 30% and 70% of the allowed more growth as height, but small productivity. Chung et al (1997) found that water deficits reduce the number of leaves per plant, leaf areas and leaf weight.…”

“…Wen et al (2001) reported that the maximum recommendable amount of nitrogen was 120 kg N ha -1 for the sandy soil condition in Japan. Barbieri et al (2017) designed an experiment that 4 evapotranspiration levels (30,70,110 and 150%,ET0) and different nitrogen doses (0, 30, 60, 90 and 120 kg/ha) were studied with two peanut varieties in Brazil. Irrigation stages were 110% of ET0.…”

The aim of research about irrigation and nutrition of peanut is to determine most suitable irrigation level and nitrogen fertilizer dose for peanut in the Harran conditions (Şanlıurfa, Turkey).In this study, different amounts of the nitrogen (N1:0, N2:40, N3:80, and N4:120 kg N ha -1 ) were applied as ammonium nitrate in two times as planting and flowering times to peanut plants. The irrigation levels were determined as 100, 75, 50, and 25% of the irrigation required and labeled as I1 (first irrigation), I2 (second irrigation), I3 (third irrigation), and I4 (fourth irrigation), respectively. In this study, positive and significant effect were found that the need protein and the increasing of peanut yield with its components were increased with 120 kg ha -1 nitrogen fertilization (N4) and no-deficit water (100%:I1) while the variable 100 fruit weight were increased with 80 kg ha -1 nitrogen fertilization (N3) and no-deficit water (100%:I1) application on plant. The plant height and 100 seed weight except 2 nd year were also increased with 80 kg ha -1 nitrogen (N3) and no-deficit water (100%:I1).

“…A maior produtividade dos sistemas irrigados frente aos cultivos de sequeiro é indiscutível. Entretanto, pensando em produtividades econômicas, curvas de respostas são essenciais na tomada de decisão sobre a quantidade de insumo a ser aplicada (BARBIERI et al, 2017). Desta forma, o objetivo deste trabalho foi avaliar a produtividade do amendoim submetido a diferentes lâminas de irrigação e sistemas de preparo do solo.…”

RESUMOA cultura do amendoim tem sido uma alternativa para melhorar a renda do produtor e, devido à fixação biológica de nitrogênio, possibilita reduzir a quantidade de adubo nitrogenado em cultivos subsequentes. Com o objetivo de avaliar a produtividade do amendoim submetido a diferentes lâminas de irrigação e condições de mobilização do solo, desenvolveu-se um experimento em solo arenoso, no munícipio de Cidade Gaúcha/PR. Empregou-se o delineamento experimental em faixas, com quatro repetições, sendo o fator sistema de cultivo (com e sem mobilização do solo) na parcela e o fator lâmina de irrigação (I0 = 0%; I1 = 22%; I2 = 64%; I3 = 100% e; I4 = 175%) na subparcela. A lâmina líquida (IL) de irrigação para elevar a umidade do solo à capacidade de campo foi definida como o tratamento I3 (100% da IL). A produtividade de amendoim com e sem casca foi estimada para a umidade de 8%, em base úmida. Concluiu-se que, a interação entre os sistemas de preparo do solo e lâminas de irrigação não proporcionou respostas significativas em termos de produtividade de amendoim; o sistema de preparo do solo com mobilização proporcionou maior produtividade de amendoim que o sistema sem revolvimento do solo; a produtividade do amendoim apresentou resposta quadrática às lâminas de irrigação aplicadas, e; quando o custo do milímetro de água for 13 vezes maior que o custo do quilograma do amendoim, a irrigação não traz retorno econômico.
