“…Comprova-se com este resultado, a grande influência da matéria orgânica para que se tenha uma produção satisfatória da cultura, tendo em vista que, a utilização de esterco bovino pode contribuir para melhorar a tolerância das plantas aos sais, e proporcionar uma melhor estruturação do solo, melhor drenagem e maior disponibilidade de nutrientes, respeitando as limitações de dosagem (SOUTO et al, 2015). De acordo com a equação de regressão (Figura 4) referente ao diâmetro do caule aos 91 DAP, verifica-se que o aumento dos níveis de esterco bovino proporcionou efeito quadrático, alcançando os maiores diâmetros (9,97; 10,92; 10,96 e 11,57), nos níveis estimados de 0, 5, 10 e 15% de MO.…”

RESUMO:A pesquisa foi conduzida em ambiente protegido no CCTA/UFCG onde objetivou-se avaliar o crescimento de plantas de algodoeiro de fibra naturalmente colorida cv. BRS Topázio, no segundo ciclo produtivo pós-poda, em solos salinosódico sob esterco bovino. Usou-se o delineamento de blocos casualizados em esquema fatorial 5 x 4, com 3 repetições, cujos tratamentos consistiram de cinco percentagens de sódio trocável -PST (13,6; 22,4; 30,1; 39,0 e 48,0%) e quatro doses de esterco bovino (0; 5; 10 e 15%). Ao encerrar a produção das plantas de algodoeiro (primeiro ciclo) realizou-se uma poda drástica, onde, após as brotações (segundo ciclo) avaliaram-se aos 51 e 91 dias após a poda (DAP) as variáveis: comprimento do ramo (CR), diâmetro do ramo (DR), diâmetro do caule (DC) e número de folhas (NF). Doses de 10% de matéria orgânica favoreceu o comprimento do ramo e, de 15% o diâmetro do ramo e do caule de plantas de algodoeiro cv. BRS Topázio aos 51 e 91 dias após a poda. Percentagens de sódio trocável de até 48% não influenciou o comprimento e o diâmetro de ramos, o diâmetro do caule e o número de folhas do algodoeiro aos 51 e 91 dias após a poda. A interação entre os fatores (PST x MO) promoveu efeito significativo sobre o diâmetro do caule de plantas de algodoeiro aos 91 DAP. Palavras-chaves:Gossypium hirsutum L., Sódio trocável, adubo orgânico. SUMMARY:The research was conducted in protected environment in the CCTA / UFCG which aimed to evaluate the growth of naturally colored hp fiber cotton plants. BRS Topaz, the second post-pruning production cycle in saline-sodic soils manure. It used the randomized block design in a factorial 5 x 4, with 3 repetitions and the treatments consisted of five percentages of exchangeable sodium -PST (13.6; 22.4; 30.1; 39.0 and 48.0 %) and four doses of cattle manure (0, 5, 10 and 15%). To cease production of cotton plants (first cycle) held a drastic pruning, where, after the shoots (second cycle) were evaluated after 51 and 91 days after pruning (DAP) variables: branch length (CR), branch diameter (DR), stem diameter (DC) and number of leaves (NF). Doses of 10% organic matter favored branch length and 15% of the diameter of the branch and cotton plants cv stem. BRS Topaz after 51 and 91 days after pruning. Exchangeable sodium in percentages of up to 48% did not influence the length and diameter of branches, the stem diameter and the number of cotton leaves at 51 and 91 days after pruning. The interaction between the factors (PST x MO) has promoted significant effect on stem diameter of cotton plants at 91 DAP.

“…In the Northeast region, okra finds favorable edaphoclimatic conditions for its development, standing out as a popular crop among small farmers (A. P. de Oliveira et al, 2014). However, in this region, due to the scarcity of rains and high evapotranspiration demand, the contents of salts in the waters usually increase during the dry season (Souto et al, 2015).…”

Excess salts in water and/or soil are a critical factor that adversely affects the physiology and growth, besides limiting the production of crops in the semiarid region of Northeast Brazil. One way to reduce the effect of salt stress on plants is by using silicon (Si) fertilization. In this context, the objective of this study was to evaluate the gas exchange, growth, and production of okra cv. Valença as a function of irrigation with saline water and Si doses. The experiment was conducted in a greenhouse in the municipality of Pombal - PB, Brazil. The experimental design adopted was randomized blocks in a 5 × 2 factorial scheme corresponding to five levels of electrical conductivity of water ECw (0.3, 1.0, 1.7, 2.4, and 3.1 dS m-1) and two doses of Si fertilization (100 and 200 g of Si per plant), with four replicates. Salt stress increased the intercellular concentration of CO2 in the substomatal chamber and reduced the CO2 assimilation rate, instantaneous carboxylation efficiency, growth, and production of okra plants. Intrinsic water use efficiency and average weights of okra fruits were not influenced by irrigation with saline water and Si doses. The supply of 200 g Si per plant reduced the deleterious effect of salt stress on stomatal conductance and leaf area of okra, at 45 days after sowing but did not increase production.

“…This species has aroused the interest of consumers due to its medicinal properties. This plant is highly adaptable to tropical countries, standing out for its ability to develop in soil, climate and extreme environment conditions (Basar et al, 2010;Souto et al, 2015a). It is considered a salinity-tolerant crop for surviving in areas flooded by tsunamis and saline environments, without presenting symptoms of foliar toxicity .…”

Irrigation is a limiting factor for the development of crops, and all water sources contain salts, which can accumulate in the soil and in the plant, compromising its development. The use of vermicompost is one of the alternatives to mitigate the negative effects of salts on plants. This organic compost is a soil conditioner and a nutrient source for plants. Thus, this study aimed to evaluate the growth and chorophyll of noni (Morinda citrifolia L.) in response to the salinity of irrigation water in substrates with and without vermicompost. A completely randomized design in a 4 × 3 factorial scheme was used, corresponding to four levels of electrical conductivity of the irrigation water (0.5, 1.5, 3.0 and 4.5 dS m-1), in three soil substrates (without humus, with 33.33 and 66.66% of humus). Three months after germination, the following variables were evaluated: plant height; stem diameter; number of leaves; chlorophyll index (a, b and total) in the leaves; and fresh and dry matter of shoots and roots. The increase of salinity in irrigation water negatively influences growth in height, stem diameter, biomass production and chlorophyll a and total indexes, but with lower intensity in substrates with humus, that improves the fertility of the substrate and favors the growth of noni plants, regardless of the salinity of the irrigation water; however, its beneficial effect decreases with the intensification of electrical conductivity of irrigation water.
