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 Due to water limitations in terms of both quantity and quality in the semi-arid region of northeastern Brazil, the use of waters with high concentrations of salts become necessary in irrigated agriculture. Thus, this study aimed to evaluate the growth and production of grafted West Indian cherry under saline water irrigation and potassium fertilization. The experiment was carried out in drainage lysimeters under protected environment conditions, using a Regolithic Neosol with sandy loam texture. Treatments resulted from the combination of two levels of electrical conductivity - ECw (0.8 and 3.8 dS m-1) of irrigation water and four doses of potassium (50, 75, 100 and 125% of the recommendation of Musser), arranged in a randomized block design, with...

Provedor de dados: Revista Brasileira de Engenharia Agrícola e Ambiental
Autores: Nobre,Reginaldo G.; Sousa,Welligton B. da; Lima,Geovani S. de; Gheyi,Hans R.; Dias,Adaan S.; Pinheiro,Francisco W. A.
ABSTRACT The cultivation of sunflower allows its use as bio-fuel and alternative forage. It is a viable alternative in the semiarid regions. Current study evaluates the effect of saline water use, sources and doses of nitrogen fertilization on the production of sunflower in the experiment conducted in drainage lysimeters between May and August 2012, under protected conditions, at Pombal - PB Brazil. The experiment consisted of a randomized block design, with a 2 x 3 x 4 factorial arrangement and three replications. The treatments consisted of two levels of electrical conductivity of water - ECw (0.3 and 3.0 dS m-1), three sources of nitrogen (urea, ammonium sulfate and calcium nitrate) and four levels of N (40, 80, 120 and 160% of recommended dose - 100 mg...

Cultivation of cherry tomato under irrigation with saline water and nitrogen fertilization
Provedor de dados: Revista Brasileira de Engenharia Agrícola e Ambiental
Autores: Vieira,Ianne G. S.; Nobre,Reginaldo G.; Dias,Adaan S.; Pinheiro,Francisco W. A.
ABSTRACT The study was carried out from August 2013 to January 2014 to evaluate growth and production of cherry tomato cultivated under irrigation with water of different salinity levels and fertilized with different nitrogen (N) doses, in experiment conducted in drainage lysimeters under greenhouse conditions, at the Center for Agrifood Science and Technology of the Federal University of Campina Grande. The statistical design was randomized blocks in a 5 x 4 factorial scheme, with three replicates, and the treatments consisted of five levels of electrical conductivity of water (0.3, 1.5, 2.5, 3.5 and 4.5 dS m-1) and four N doses (60, 100, 140 and 180 mg kg-1). Growth and production variables of cherry tomato decrease linearly from the irrigation water...

Autores: Lima,Geovani S. de; Dias,Adaan S.; Soares,Lauriane A. dos A.; Gheyi,Hans R.; Nobre,Reginaldo G.; Souza,Leandro de P.
ABSTRACT This research was conducted in order to evaluate the growth and production of colored-fiber cotton, cv. ‘BRS Rubi’, irrigated with water of different salinities and nitrogen (N) doses. The experiment was carried out in drainage lysimeters filled with soil material from an eutrophic Regolithic Neosol with sandy-loam texture under greenhouse conditions in Campina Grande, PB. The experiment was conducted in a randomized block design and the treatments consisted of five levels of irrigation water salinity with the following electrical conductivities - ECw (5.1, 6.1, 7.1, 8.1 and 9.1 dS m-1), combined with five N doses - ND (65; 100; 135; 170; 205 mg of N kg-1 of soil), distributed in a 5 x 5 factorial scheme with three replicates. The growth of the...

ABSTRACT The problem of the lack of adequate water resources for agriculture has intensified in recent years, making it necessary to use waters with relatively high concentration of salts for the irrigation of crops all over the world. The objective of this study was to evaluate the influence of potassium (K) fertilization as a salt stress attenuator on gas exchanges and photochemical efficiency of West Indian cherry. The crop was cultivated under greenhouse conditions in the municipality of Campina Grande, PB, in lysimeters filled with 250 kg of sandy loam soil. Treatments were distributed in randomized blocks, in a 2 x 4 factorial scheme, with two levels of electrical conductivity of irrigation water - ECw (0.8 and 3.8 dS m-1) and four K doses (50, 75,...
