| Visando avaliar o crescimento e a capacidade produtiva de diferentes genótipos de gergelim em função de lâminas de irrigação, foi realizado um experimento na Estação Experimental da Embrapa, em Barbalha, CE, onde foram estudados cinco lâminas de irrigação e seus efeitos em três genótipos de gergelim. Esses fatores combinados resultaram em 15 tratamentos. O delineamento experimental foi em faixas, com quatro repetições, resultando em 60 unidades experimentais. Foi realizada análise de crescimento destrutiva com amostragens de 15 em 15 dias para avaliação de área foliar e fitomassa. As variáveis de crescimento foram estudadas em 10 plantas da área útil das parcelas. Ao final do ciclo foram avaliados a produção e seus componentes. Os maiores valores dos... |

| ABSTRACT The study aimed to evaluate the effects of irrigation with saline water and fertilization with nitrate (NO3--N) and ammonium (NH4+-N) ratios on growth, flowering, water consumption and water use efficiency of the sesame cv. CNPA G3. The treatments were distributed in randomized blocks in a 5 x 5 factorial with three replicates, referring to five levels of electrical conductivity of the irrigation water - ECw (0.6, 1.2, 1.8, 2.4 and 3.0 dS m-1) and nitrate (NO3--N) and ammonium (NH4+-N) (200/0, 150/50, 100/100, 50/150, 0/200 mg kg-1) ratios. Irrigation with saline water above 0.6 dS m-1 inhibited the growth, delayed flowering and promoted early maturation of capsules of sesame, cv. CNPA G3. The proportion of 0/200 mg kg-1 of NO3--N/NH4+-N promoted... |

| ABSTRACT The sesame crop has stood out due to the high nutritional content of its seeds, in addition to being able to be cultivated in the tropical and subtropical regions such as Northeast Brazil. Thus, it is necessary to identify the physiological, biochemical and productive changes related to the tolerance to stress. Objective of this study was to evaluate the physiological, biochemical and productive aspects of sesame genotypes as a function of different rates of water replenishment. The experiment was carried out at the Embrapa Cotton Experimental Unit, located in the municipality of Barbalha-CE, Brazil, under field conditions. The experiment was carried out in a randomized complete block design, with treatments in a factorial scheme (4 × 6),... |

| ABSTRACT Sesame is an oilseed that has low demand of water; it is widely grown in tropical regions, but few studies had been conducted on its mineral nutrition. The objective of this study was to evaluate physiological and production variables of two sesame genotypes (BRS-Seda and Preto) varying the organomineral fertilizer doses, via fertigation. The genotypes were grown under field conditions during the 2014/2015 dry season, in an agricultural area in Lagoa Seca, PB, Brazil. The two genotypes were subjected to five doses (0, 30, 60, 90 and 120% of the nutritional requirement of the crop) of an organomineral fertilizer based on sugarcane vinasse, and to an additional treatment consisting of mineral fertilizer (100% of the crop requirement). The experiment... |

| ABSTRACT Sesame is an important crop in Northeast Brazil, where climate conditions require adapted genotypes and alternatives for plant defense against drought. This study aimed to evaluate the salicylic acid as drought attenuator in sesame genotypes. The experiment evaluated six genotypes (BRS Seda, CNPA-G2, CNPA-G3, CNPA-G4, LAG-Branquinha and LAG-Pretinha), five osmotic potentials (0, -0.2, -0.4, -0.6 and -0.8 MPa) and three seed treatments (soaking in distilled water, in salicylic acid and no treatment). CNPA-G4 is tolerant to drought in the germination stage. Salicylic acid at 10-5 M induced tolerance to drought stress in sesame, but it is necessary to test other concentrations. |
