“…O crescimento vegetativo da planta está diretamente relacionado com a temperatura, de tal forma que a velocidade de surgimento das folhas na haste principal aumenta com a temperatura, sendo maior em torno dos 30 o C (Ono, 1979;Leong & Ong, 1983). A temperatura, além de afetar o crescimento vegetativo, influencia o início do florescimento; as temperaturas abaixo de 25-27 o C ocasionaram um retardamento deste estágio (Ketring, 1979).…”

RESUMO -Este trabalho teve por objetivo estudar o efeito do calcário, como fornecedor de cálcio, em diferentes épocas de semeadura, na cultura do amendoim cultivar Tatu, sobre os componentes da produção e a produtividade de vagens em semeadura na época considerada seca. O experimento foi conduzido em um Latossolo Vermelho-Escuro, argiloso, em Selvíria, MS. Foram estudadas quatro épocas de semeadura do amendoim da seca (21/1, 4/2, 18/2 e 4/3), combinadas com quatro doses de Ca (0, 45, 90 e 135 kg ha -1 de Ca), aplicadas no sulco de semeadura, usando como fonte calcário dolomítico com PRNT de 90,1% e com teores de 21% de CaO e 18% de MgO. Foram avaliados o número de vagens por planta, o número de grãos por vagem e por planta, o peso de 100 grãos, o rendimento e a produtividade das vagens. Conclui-se que: 1) à medida que se atrasa a semeadura, há a probabilidade de ocorrer deficiência hídrica nos períodos vegetativo e reprodutivo, reduzindo a produtividade do amendoim da seca; 2) há boa produtividade de vagens quando a semeadura é realizada até o início do mês de fevereiro; 3) a resposta do amendoim da seca ao Ca é baixa em solos onde inicialmente se tem alto teor de Ca e saturação por bases considerada média, principalmente, quando a disponibilidade hídrica também é um fator limitante; 4) a aplicação de calcário no sulco de semeadura como meio de fornecimento de Ca para a cultura do amendoim é uma prática viável.Termos para indexação: calagem, rendimento de colheitas, vagens, peso. PRODUCTIVENESS AND YIELD COMPONENTS IN DRY SEASON PEANUT AS AFFECTED BY PLANTING TIME AND CALCIUM FERTILIZATIONABSTRACT -The effect of Ca fertilization and sowing time on yield components and peanut pod yield in the dry season was studied. The experiment was conducted under field conditions in a DarkRed Latosol, loamy texture, in Selvíria, MS, Brazil. Four sowing times (Jan. 21, Feb. 4, Feb. 18, and Mar. 4) were combined with four calcium levels (0, 45, 90 and 135 kg ha -1 of Ca), applied at the sowing time, into the furrows, utilizing dolomite limestone with PRNT 90.1% (21% of CaO and 18% of MgO). The number of pods per plant, number of grains per pod and per plant, 100 grains weight, hulled grains yield and peanut pod yield were determined. It is concluded that: 1) as the sowing is delayed, a water stress may occur in the growing period, and in the reproductive period, reducing the dry-season peanut crop productiveness; 2) there are good yields if planting is accomplished at the beginning of February; 3) the response for Ca fertilization is low in soils with high Ca level and medium basis saturation, specially when water conditions are also a limiting factor during dry season crop; 4) lime applied at the sowing time into the furrows is recommended.

“…It is evident that extremes of soil temperature limit reproductive growth and yield of peanut (Ono, 1979;Ong, 1986). Studies of effects of air temperature on peanut are most commonly reported, but information about the effect of soil temperature is comparatively sparse (Cox, 1979;Leong and Ong, 1983;Nigam et al, 1983).…”

Extremes of soil temperature limit yield development of peanut. To obtain information relevant to improving yield by agronomic management and breeding, the in fluence of the soil temperature regimes (day/night) of 20/14 (Tl), 26/20 (T2), 32/26 (T3), and 38/32 C (T4) imposed from the time of peg penetration into the soil until maturity on growth and development of three Spanish genotypes of peanut (Arachis hypogaea L.) was investigated in a greenhouse. $oil temperature treat ments were imposed by placirfg pots with individual plants in large temperature-controlled water baths. With increasing soil temperature from Tl to T3, leaves, stems and lateral roots became thinner. The leaf area increased from Tl to T3. The lateral root length increased up to maturity more at higher than at lower temperatures. The number of mature pods per plant, mature single seed mass, and therefore mature total seed mass per plant were highest at the intermediate temperature regimes, less at the warmest, and lowest at the coldest treatment. In early reproductive stages, pod inititation rate in creased with decreasing soil temperature. Total pod growth and development of mature pods was lowest in Tl, although pod initiation was high. Suboptimal soil temperatures slowed pod filling and maturation. At T4, one reason for the lower mature pod number compared to the intermediate temperature treatments seems to be the low pod initiation rate at early reproductive stages. These responses to temperature suggest agronomic management and genetic options for increasing yield at

“…Bagnall and King [31,32] later proposed that peanut should be classified as a short day plant because flowering was significantly enhanced during short-day photo periods. Thus far, many authors [33][34][35] continue to refer to species in the genus Arachis as day neutral plants with respect to their reproductive performance. The results presented in this paper agree with other field studies [31][32][33] indicating short day-length-induced flowering in Arachis.…”

Arachis paraguariensis, a wild peanut species, is a potential experimental system for studying the molecular mechanisms of flowering in the genus Arachis. The present study was carried out to investigate the effect of photoperiod on in vitro reproductive behavior of five genotypes of A. paraguariensis. Day-lengths of 12, 16 and 24 h were tested to monitor in vitro flowering using growth chambers kept at 26˚C ± 1˚C and 60% ± 5% relative humidity under an illumination of 40 μmol·m . Flowering percentage of plantlets ranged from 35% to 93%, 20% to 75%, and 5% to 53% for 12, 16 and 24 h day-lengths, respectively. Genotype PI 262842 displayed the highest frequency of flowering under all the day-length treatments but in vitro flower bud initiation was delayed. The highest mean flowering percentage of 65% across all the genotypes for plantlets exposed to 12 h photoperiod is indicative that flowering induction actually occurred. The results presented in this paper provide evidence for photoperiodic flowering response as well as the occurrence of short day-length-enhanced flowering in A. paraguariensis.
