ABSTRACT The objective of this research was to evaluate the growth and formation of fresh and dry weight of ‘Crioula’ guava rootstock irrigated with waters of different saline levels and nitrogen (N) doses, in an experiment conducted in plastic tubes under greenhouse conditions. The experimental design was randomized blocks, in a 5 x 4 factorial scheme with four replicates, and the treatments consisted of five levels of water electrical conductivity - ECw (0.3, 1.1, 1.9, 2.7 and 3.5 dS m-1) and four N doses (70, 100, 130 and 160% of the N dose recommended for the cultivation of guava seedlings, cv. ‘Paluma’). The dose referring to 100% corresponds to 773 mg of N dm-3. The highest growth of ‘Crioula’ guava rootstock was obtained with ECw of 0.3 dS m-1 and fertilization of 541.1 mg N dm-3 of soil; increasing N doses did not reduce the deleterious effect of the salt stress on the growth and phytomass formation of ‘Crioula’ guava rootstock; irrigation with water of up to 1.75 dS m-1, in the production of guava rootstocks, promotes acceptable reduction of 10% in growth and quality of the seedlings.

This study aimed to evaluate growth and quality of soursop seedlings cv. Morada Nova, as a function of saline water irrigation and exogenous applications of hydrogen peroxide (H2O2), under greenhouse conditions. The experimental design used was randomized blocks in 5 x 5 factorial scheme, corresponding to the combination of five levels of irrigation water electrical conductivity – ECw (0.7, 1.4, 2.1, 2.8 and 3.5 dS m-1) and five concentrations of hydrogen peroxide (0, 25, 50, 75 and 100 µM). The results showed that Hydrogen peroxide concentrations were applied by soaking the seed for 24 h and by spraying on all leaves of soursop seedlings. Irrigation water above electrical conductivity of 0.7 dS m-1 negatively affected growth and quality of soursop seedlings cv. Morada Nova. The dry phytomass of root was the most sensitive variable to saline stress. Hydrogen peroxide concentrations of 31 and 100 µM led to highest relative growth rate in leaf area and dry phytomass of leaves and stem, respectively. The quality of soursop seedlings cv. Morada Nova was not compromised by using water with electrical conductivity of 3.5 dS m-1 in irrigation.

ABSTRACT The study was conducted to evaluate the growth and physicochemical quality of West Indian cherry cv. BRS 366-Jaburu, as a function of saline water irrigation and potassium fertilization. The research was conducted under greenhouse conditions in Campina Grande-PB. The experimental design was randomized blocks in a 2 x 4 factorial arrangement, which consisted of two levels of irrigation water electrical conductivity - ECw (0.8 and 3.8 dS m-1) and four levels of potassium of 50, 75, 100 and 125% of the recommendation, in which the dose of 100% was equivalent to 19.8 g of K2O per plant year-1, with three replicates and one plant per replicate. Water salinity of 3.8 dS m-1 inhibited the absolute and relative growth in diameter of the rootstock and scion of West Indian cherry plants, in the period from 100 to 465 days after transplanting. The interaction between saline levels and potassium doses was significant for hydrogen potential, soluble solids and anthocyanins levels in BRS 366-Jaburu West Indian cherry fruits, with the highest values obtained in plants fertilized with 125, 125 and 50% of the K2O recommendation and under water salinity of 3.8, 3.8 and 0.8 dS m-\ respectively. Increasing doses of K did not attenuate the effects of salt stress on the relative growth in rootstock stem diameter, fruit polar diameter and anthocyanin contents of West Indian cherry. Soluble solid contents in West Indian cherry pulp increased with application of K2O.

O delineamento experimental foi inteiramente casualizado, com cinco repetições, em esquema fatorial 5 × 2, relativo à condutividade elétrica da água de 0,5; 1,0; 2,0; 3,0 e 4,0 dS m-1, no substrato sem e com biofertilizante bovino. Aos 95 dias após a emergência foram avaliadas a condutividade elétrica do extrato de saturação do solo, o crescimento das mudas em altura da haste principal, diâmetro do caule, número de folhas, área foliar, comprimento da raiz principal, biomassa seca total e índice de qualidade de Dickson. O biofertilizante, exceto no comprimento radicular, promoveu maior crescimento e melhor qualidade em mudas de jaqueira sob irrigação com água salina. A irrigação com água de até 1,75 dS m-1 não compromete a qualidade das mudas de jaqueira.   Palavras-chave: Artocarpus heterophyllus Lam., salinidade, insumo orgânico, crescimento inicial     MESQUITA, F. de O.; CAVALCANTE, L.

BOVINE BIOFERTILIZER AND SALINE WATER ON JACKFRUIT SEEDLING PRODUCTION     2 ABSTRACT   The objective of the present experiment was to evaluate bovine biofertilizer as an attenuator in the formation of salted irrigated jackfruit seedlings in a protected environment, at Centro de Ciências Agrárias, Universidade Federal da Paraíba, Areia, Paraíba, Brazil. The experimental design was completely randomized, with five replications, in a factorial scheme 5 × 2, relative to the electrical conductivity of water of 0.5; 1.0; 2.0; 3.0 and 4.0 dS m-1 on the substrate without and with bovine biofertilizer. Electrical conductivity of the soil saturation extract, the growth of the main stem height, stem diameter, number of leaves, leaf area, main root length, total dry biomass, and Dickson quality index were evaluated at 95 days after emergence. The biofertilizer, except for root length, promoted greater growth and better quality in jackfruit seedlings under irrigation with saline water. Irrigation with water up to 1.75 dS m-1 does not compromise the quality of jackfruit seedlings.   Keywords: Artocarpus heterophyllus Lam., salinity, organic input, initial growing.
