“…Due to the simultaneous actions of salinity and sodicity, the presented data are similar to those observed by Diniz et al (2013) and Mesquita et al (2015), and Pazhanivelan et al (2006) and Campos et al (2011), respectively. The first two studies showed that although common biofertilizer inhibited the action of salinity in irrigation water during neem seedling formation, plant growth was compromised with increasing electrical conductivity of the irrigation water.…”

Growth and Regrowth of Neem After Cutting in Saline - Sodic Soil Treated With Organic Inputs

et al. 2017

-Soil salinity and sodicity are global problems since both promote the physical, chemical and biological degradation of soil, jeopardising the productive capacity of agricultural fields. Inorganic correctives or organic inputs are applied as an attempt to reduce the problem, alongside the use of salt-tolerant plants. This study aimed at evaluating the effects of organic inputs on the growth of neem (Azadirachta indica) strains in saline-sodic soil after cutting. Treatments were arranged in a randomised block design, with four replicates in a 3 × 5 factorial. Organic inputs -bovine manure, common bovine biofertilizer (equal parts of water and fresh bovine manure) and chemically enriched biofertilizer (common biofertilizer components combined with plaster, sugarcane molasses and cow's milk) -were applied only once, after soil washing, two days prior to seeding, at the levels of 0, 3, 6, 9 and 12% of the substrate volume. Except effects on the stem diameter, the most efficient input was bovine manure, with strong effects on the height increase and biomass yield of neem plants after cutting, especially in treatments at a level greater than 6%. The organic inputs, despite increasing the soil salinity and sodicity in the interval between washing and cutting, stimulated biometric growth and biomass formation in saline-sodic soil.Keywords: Azadirachta indica.

REBROTA E CRESCIMENTO DO NIM APÓS O CORTE EM SOLO SALINO -SÓDICO TRATADO COM INSUMOS ORGÂNICOSRESUMO -A salinidade e a sodicidade dos solos são problemas mundiais porque promovem a degradação das propriedades físicas, químicas e biológicas dos solos e comprometem a capacidade produtiva das áreas agrícolas. Uma das tentativas de redução do problema é a aplicação de corretivos inorgânicos ou insumos orgânicos associados com plantas tolerantes aos sais. Pelo exposto, o trabalho objetiva avaliar o efeito de insumos orgânicos na rebrota de cepas de nim (Azadirachta indica) após o corte no crescimento das plantas em solo salino -sódico. Os tratamentos foram arranjados em blocos ao acaso, com quatro repetições em esquema fatorial 3 × 5, referentes aos insumos orgânicos -esterco bovino, biofertilizante bovino comum (partes iguais de água e esterco fresco de bovino) e biofertilizante enriquecido quimicamente (componentes do biofertilizante comum associados a gesso, melaço de cana -de -açúcar e leite de vaca), aplicados uma única vez, após a lavagem do solo, dois dias antes da semeadura das sementes, aos níveis de 0, 3, 6, 9 e 12 % do volume do substrato. Exceto no diâmetro caulinar, o esterco bovino foi mais eficiente que os biofertilizantes no crescimento em altura e rendimento em biomassa das plantas de nim após o corte, principalmente nos tratamentos em níveis acima de 6 %. Os insumos orgânicos apesar de elevarem a salinidade e a sodicidade do solo no intervalo do final da lavagem até o corte das plantas, estimularam o crescimento biométrico e a formação de biomassa do nim em solo salino sódico.Palavras-chave: Azadirachta indica.

“…On the other hand, Diniz et al (2013) and Mesquita et al (2015) found that neem behaves as a moderately salt stress sensitive plant. The present study aimed at evaluating the effects of bovine manure and biofertilisers applied after washing on soil salinity and sodicity and on growth and regrowth after cutting of neem cultivated in pots.…”

“…Although the soil without leaching has higher saline level compared to the soil with leaching when irrigated with nonsaline water (0.5 dS m -1 ), the increment of salts in the irrigation water significantly increased the saline condition of the soil in the treatments with leaching. This situation, as also observed by Diniz et al (2013), evidences that, despite the positive effect of soil leaching, this practice does not avoid the increment of salts in the soils through the irrigation with water of increasing salinity.…”

“…Chemical attributes regarding fertility and salinity and physical attributes, before installing the experiment leaching fraction equivalent to 10% was applied and the volume was recorded. After that, all the values were added in order to obtain the total volume applied each week (Ayers & Westcot, 1999;Diniz et al, 2013). For the treatments without leaching, irrigation continued to be based on the weighing method.…”

The response of plants to salt stress is an extremely complex phenomenon that involves morphological, physiological and biochemical changes, modifying the leaf contents of chlorophyll and carotenoids, among others and affecting plant growth, development and production. An experiment was carried out from July 2010 to June 2011, in order to evaluate the contents of chlorophyll a, chlorophyll b, total chlorophyll, carotenoids, the chlorophyll a/b ratio and biomass accumulation of shoots and roots of noni plants, when subjected to irrigation and leaching with water of increasing salinity. The experiment was carried out in a greenhouse, at the Center of Agricultural Sciences of the Federal University of Paraíba, in the municipality of Areia-PB, Brazil. Treatments were distributed in randomized blocks, in a 5 × 2 factorial scheme with four replicates and two plants per plot, and corresponded to levels of electrical conductivity of irrigation water (0.5; 1.5; 3.0; 4.5 and 6.0 dS m-1) in pots with and without leaching. The increase in irrigation water salinity impairs the leaf contents of chlorophyll a, b, total chlorophyll, carotenoids and biomass production of noni plants, but to a lesser extent in all the treatments in which same irrigation water was used for leaching.

“…Cavalcante et al (2010), evaluating seedling growth of the same crop under irrigation with saline water from a surface dam and with water enriched with NaCl and Na2SO4, with 0.4, 2.0, 4.0, 6.0, and 8.0 dS m -1 EC, without using the leaching fraction, observed that salinity reached 11.05, 8.80 and 7.56 dS m -1 , respectively. Lower salinity levels indicates the importance of the 10% leaching fraction in addition to soil by the agriculture's restrictive water (Rhoades et al, 2000;Diniz et al, 2013), and provides greater plant growth even under salt stress.…”

Water used for irrigation in semiarid regions of the world is not always of good quality, and may contain salts levels that inhibit plants growth. This study was conducted to evaluate the growth of papaya (Carica papaya L.) 'Golden' seedlings irrigated with saline water in soil with and without bovine biofertilizer produced by anaerobic fermentation of a mixture of fresh bovine manure and water. The experiment was carried out in Areia County, Paraiba State, Brazil. Treatments were distributed in randomized blocks using a factorial design 5 × 2 relative to five salinity levels in irrigation water of 0.5, 1.0, 2.0, 3.0 and 4.0 dS m -1 in soil with and without bovine biofertilizer, corresponding to 10% of the substrate volume. At 90 d after emergence (DAE), both the electrical conductivity (EC) in soil saturation extract, biometric growth and DM production of papaya seedlings were evaluated. Increased salinity from 0.5 to 4.0 dS m -1 raised, within 90 DAE, soil EC of saturation extract (ECse) from 1.19 to 3.95 dS m -1 and from 1.23 to 3.63 dS m -1 in treatments with and without bovine biofertilizer, respectively. Also, the increase in water salinity from 0.5 dS m -1 to the estimated maximum values ranging from 1.46 to 2.13 dS m -1 stimulated seedling height to 11.42 and 18.72 cm in soil with and without bovine biofertilizer, respectively. Higher salinity levels in irrigation water increased soil salinity levels to values that inhibited both growth and quality of papaya seedlings, but with less severity when treated with bovine biofertilizer.
