“…Corroborating with the results of Silva et al (2009), it was observed that the nutrient application (via seeds or leaf) did not affect the peanut seed yield. This result is in contrast with Hippler et al (2011), who reported that nutrient application affects the productivity of peanuts (Arachis hypogea L.). Silva et al (2012), studied the efficiency of micronutrient products on the peanut yield and concluded that there was a significant response of productivity to Mo application, when applied through seeds.…”

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 × 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.

“…Assessing the interaction between increasing doses of P and native mycorrhizal fungi, Hippler et al (2011) concluded that phosphorus fertilization enhanced the development of peanut plants (Runner IAC 886), regardless the inoculation with native fungi. For Malavolta et al (1997) the P function is related to energy production in plants, stored as adenosine triphosphate (ATP) and adenosine diphosphate (ADP).…”

“…Calcium and phosphorus are essential for flowering and the development of pods and seeds, while K promotes the vegetative development DAVIS 1995). However, the responses of peanut crop to fertilization with nitrogen, phosphorus, and potassium are contradictory, with reports of positive (THIMMEGOWDA 1993;MARUBAYASHI et al, 1997;BASU et al, 2008;HIPPLER et al, 2011), negative (GERIN et al, 1996SPINOLA;CÍCERO 2002) and absence of responses (KASAI et al, 1998;PARKER 2006).…”

Phosphorus (P) and potassium (K) fertilization can maximize the profitability of peanut cultivation. Therefore, the aim of this study was to evaluate the basic fertilization with P and K on the grain yield and production components of creeping peanut. The experiment was performed in a randomized block design, in a 2 x 3 + 1 factorial scheme. Two doses of K (30 and 60 kg ha-1 of K2O) and three levels of P (60, 90 and 120 kg ha-1 of P2O5) at sowing and an additional treatment without the basic fertilization were used, with four replicates. The cultivar Runner IAC 886was adopted. The following traits were evaluated: pod yield, grain yield, number of pods per plant, number of pods with grains per plant, the percentage of pods without grains, 100 grains weight and number of seeds per pod. P and K fertilization at sowing promote an increase in creeping peanut of about 38 and 49% in pod yield and grain yield, respectively. The highest values of pods with grains are observed with the application of 120 kg ha-1 P.

“…Plantas inoculadas com G. rosea apresentaram os maiores índices de dependência micorrízica, entre 40 e 37% nas menores concentrações de P (0 e 75 mg kg -1 de P, respectivamente), dentre todos os tratamentos, enquanto as plantas inoculadas com G. clarum apresentaram dependência micorrízica de 27% na dose 0 mg kg -1 de P (Figura 6). Essa dependência ocorre também em relação a inoculação do amendoinzeiro com FMA nativos em diferentes doses de P, neste caso, plantas inoculadas com G. rosea, sendo que apresentam a maior dependên-cia micorrízica quando supridas com 60 mg kg -1 de P (Hippler et al, 2011). Nas maiores doses de P (150 e 250 mg kg -1 de P) o amendoinzeiro não apresentou dependência positiva para nenhum dos endófitos inoculados.…”

ResumoO amendoinzeiro responde positivamente quanto à produção de grãos quando associado a fungos micorrízicos arbusculares (FMA), porém é necessário verificar sua dependência para diferentes espécies em diferentes níveis de fósforo (P). Este trabalho teve por objetivo determinar a dependência micorrízica de Arachis hypogea L. cv. Runner IAC 886 sob diferentes concentrações de P, e avaliar o desenvolvimento do hospedeiro e do endófito após a colonização. O experimento foi conduzido em casa de vegetação, em delineamento inteiramente casualizado, com duas espécies de FMA (Gigaspora rosea e Glomus clarum) e um controle não inoculado, combinados com quatro doses de P aplicados no solo: 0, 75, 150 e 250 mg kg -1 . Após 50 dias da germinação do amendoim, foram avaliados a matéria seca (MS), a colonização radicular, o número de esporos no solo, a dependência micorrízica e a disponibilidade de P. Verificou-se que as plantas de amendoim apresentaram dependência micorrízica à inoculação com a espécie G. rosea nos tratamentos com baixo suprimento de P e com G. clarum somente na ausência do nutriente. A inoculação com G. rosea proporcionou maior produção de MS total na dose de 75 mg kg -1 de P (7,2 g por planta), sendo que houve aumento no acúmulo de P na parte aérea até na maior dose de 250 mg kg -1 de P. Já a espécie G. clarum apesar de ter proporcionado maiores números de esporos e colonização radicular, apresentou o menor crescimento das plantas e menor eficiência na utilização de P pela parte aérea.Palavras-chave: fungos micorrízicos arbusculares, Arachis hypogea, adubação fosfatada. Mycorrhizal dependence of peanut plants on phosphorus levelsAbstract Peanut grains production responds positively when associated to arbuscular mycorrhizal fungi (AMF), but it is necessary to determine its dependence on phosphorus (P) supply for in different species in plants. The aim of this study was to determine the mycorrhizal dependency of Arachis hypogea L. to different P levels and to evaluate the development of host and endophyte after colonization. A greenhouse experiment was carried out in completely randomized design, with two mycorrhizal fungi species (Gigaspora rosea and Glomus clarum) and a control without the fungus, and also with different P levels applied to the soil (0, 75, 150 and 250 mg kg -1 of P). After 50 days of groundnuts germination, there were evaluated dry weight (DW), root colonization, number of spores in the soil, mycorrhizal dependency and available P. The peanut plants showed mycorrhizal dependency when inoculated with G. rosea in low supply of P and for G. clarum only in the absence of the nutrient. The inoculation with G. rosea produced higher DW with 75 mg kg -1 of P (7.2 g per plant), whereas there was an increase in the accumulation of P in shoots up to the highest dose (250 mg kg -1 ) of P. Although G. clarum provided higher number of spores and root colonization ratio, it had the lowest plant growth and also lower P use efficiency by shoots.
