“…Plant growth can be inhibited by high salt concentrations through osmotic stress, nutritional imbalance, and specific ion toxicity (Alam 1994;Jacoby 1994;Munns and Tester 2008). It is known that the growth inhibition and the adverse effects induced by salinity can be alleviated by proper use of fertilizer and water management, depending on plant species, salinity level, and environmental conditions (Shen et al 1994;Soliman et al 1994;Albassam 2001;fertilization with N may contribute to soil salinization and increase the negative effects of soil salinity on plant performance (Villa-Castorena et al 2003). In addition, the potential for NO 3 leaching may increase where moderate to high amounts of salts are present in the soils because plants under salt stress can not absorb and or utilize the applied N as efficiently as the plants not subjected to salt stress (Ward et al 1986;Pessarakli and Tucker 1988;Bowman et al 2006).…”

The influences of different N fertilization rates and soil salinity levels on the growth and nitrogen uptake of cotton was evaluated with a pot experiment under greenhouse conditions. Results showed that cotton growth measured as plant height was significantly affected by the soil salinity and Nsalinity interaction, but not by N alone. Cotton was more sensitive to salinity during the emergence and early growth stages than the later developmental stages. At low to moderate soil salinity, the growth inhibition could be alleviated by fertilizer application. Soil salinity was a dominated factor affecting cotton's above-ground dry mass and root development. Dry mass of seed was reduced by 22%, 52%, and 84% respectively, when the soil salinity level increased from control level of 2.4 dS m −1 to 7.7 dS m −1 , 12.5 dS m −1 and to 17.1 dS m −1 , respectively. N uptake increased with N fertilization at adequate rates at both low and medium soil salinities but was not influenced by over N fertilization. At higher salinities, N uptake was independent of N rates and mainly influenced by soil salinity. The uptake of K decreased with soil salinity. The concentration of Na, Cl and Ca in plant tissues increased with soil salinity with highest concentrations in the cotton leaf.

“…In other studies, fertilizations above 140 kg.ha -1 of N, under greenhouse conditions with an average maximum temperature of 30 °C, caused a decrease in yields of the hybrid bell pepper "Sandia" due to an exaggerated osmotic effect from salts and fertilizers content (Villa, Ulery, Catalán & Remmenga, 2003).…”

“…In Colombia, in 2014, the national area harvested for consumption was 2378 hectares of which 320 were established in Antioquia, and about 99%, under open field conditions (Agronet, 2017). Villa, Ulery, Catalán & Remmenga (2003), found differences between the yields and treatments in "Sandia" hybrid which was grown under greenhouse conditions in two growing seasons (31 and 35°C ), with different N doses and in a soil with several salinity levels. Nevertheless; yields increased as well as N levels in lower temperature, while up to 35°C, yields decreased and soil salinity increased.…”

Some unappropriated techniques are found in bell pepper agricultural management. Those are: non-balancing nutritional profile among soil contribution, crop requirements and fertilizer efficiency, excessive use of composite sources and the lack of availability of studies on recommendations in different environments where this crop is grown. In order to mitigate the inadequate techniques in the agronomic management of bell pepper, an evaluation of four fertilization treatments under open field and protected conditions with plastic cover was conducted. Nathalie cultivar was grown during 2014-B and 2015-A at "Corporación Colombiana de Investigación Agropecuaria", -CORPOICA research center, located in Llanogrande, township of Rionegro (Antioquia, Colombia). The treatments (T) evaluated were: T1: 250, 75, 180 and 90; T2: 170, 50, 120 and 60; T3, 100, 40, 80 and 40 and T4: 60, 25, 50 and 25 kg.ha -1 of N, P 2 O 5 , K 2 O and MgO, respectively. T2 and T4 correspond to crop requirements established by previous research. In addition, simple sources were used as follows: Urea, DAP, Potassium chloride and Magnesium sulphate, which were arranged in a split-plot design. For the relative crop growth rate (TCR) and yield variables, differences were shown under two evaluated conditions. In open field condition, the highest production and stem diameter were recorded; there were not differences among treatments. T3 is recommended because it showed similar yield to the other three ones. This Treatment allowed reestablishing and maintaining soil fertility levels, with a rational, efficient and low use of fertilizers, without generating contamination and salinity problems.Key words: Agronomic management, Capsicum annuum, crop relative growth rate, open field condition, protected with plastic cover, yield.

“…Salinity hampers watermelon growth more during vegetative phase [17] .Therefore, the present study was conducted with an objective to ameliorate watermelon salt tolerance by using 24-epibrassinolide, a highly active and stable steroidal hormone [18] . For this purpose, watermelon plants were sprayed with 24-epibrassinolide solution and the effects of salt exposure for 28 days on growth and photosynthesis parameters were studied.…”

Keywords: 24-epibrassinolide, watermelon, salt stress, relative growth rate, gas exchange. Abstract. The present study investigates the role of 24-epibrassinolide (EBL) in inducing plant tolerance to salinity. Seedlings of watermelon (Citrullus lanatus L.) were grown in the presence of 70 mM NaCl and were sprayed with 10 -6 M EBL at 7 days after transplantation and were sampled at 28 day. The plants exposed to NaCl exhibited a significant decline in relative growth rate, net CO2 assimilation, stomatal conductance, transpiration and water use efficiency. However, the follow up treatment with EBL significantly improved the above parameters. EBL treated plants had greater relative growth rate compared to untreated plants when exposed to salt stress. Application of EBL increased photosynthesis by increasing stomatal conductance in both control and salt stressed plants and may have contributed to the enhanced growth. The water use efficiency was improved because CO2 assimilation is more important than the transpiration.
