The monitoring of plants growth constitutes an important activity during the crops formation, including the yellow passion fruit. In this direction, an experiment was carried out in Remigio, Paraiba State, Brazil, to evaluate the effects of saline water irrigation, bovine biofertilizer and potassium on yellow passion fruit growth plants and soil salinity. Treatments were arranged in randomized block with three replications and 12 plants per plot, using factorial design 2 x 2 x 2, relative electrical conductivity of irrigation water of 0.35 to 4.00 dS m-1 , in soil with and without biofertilizer and potassium chloride (KCl) conventional and coated with polymers. The variables studied were electrical conductivity of the soil at depths of 0-20 and 21-40 cm, plant height at 30 days after transplanting (DAT), period of the seedlings transplanting to pruning of the main haste and lateral branches, number of productive branches and stem diameter at 30, 90, 150, 210 and 270 DAT. The interaction between water salinity, biofertilizer and potassium increased the soil salinity. The biofertilizer and the slow release of KCl increased the plant growth in height, anticipating the main stem pruning and productive side branches, productive branches number and stem diameter of the plants.
Growth and Development of Passion Fruit Seedlings under Irrigation with Salt Water and Biofertilizer
Journal of Experimental Agriculture International, 2019
The yellow passion fruit is a plant climbing botanically that has a good geographical distribution in Brazil, with more than 150 species in the country. The presence of salts in soil and irrigation water is one of the main obstacles in agriculture in the world, caused by low rainfall and high evapotranspirative rates causing the salts to accumulate in the soil. However, alternatives have been sought to try to mitigate such limitations of seedling production, such as the use of biofertilizers in the soil. In this way, the objective was to evaluate the growth and development of yellow passion fruit seedlings under the effects of irrigation water salinity and the use of bovine biofertilizer on the substrate. An experiment was carried out in a greenhouse in the Center for Agrarian Sciences and Biodiversity, from october/2017 tomarch/2018, in county of Crato-Ceara, Brazil. The substrate used was the first 20 cm material of a yellow Red Argisol. The experimental design was completely rand...

EFFECT OF SALINE STRESS ON GROWTH OF FRUIT PLANTS (REVIEW ARTICLE
Mesopotamia J. of Agric, 2020
Soil and irrigation water salinity are among the main problems hindering agricultural development, especially in arid and semi-arid regions, which depends on especially surface irrigation as the main means in agriculture. The salinity lead to low growth and production of plants, including fruit, as a result of the temporal, azalotic, or nutrients imbalance. Salinity of the soil or irrigation water greatly reduces the growth, productivity and quality of fruit crops by affecting their physiological, chemical and biological functions as they cause obstruction to the absorption of some elements by the plant and if it increased absorption of salts, it causes ion poisoning of the cell, as well as increased salts cause less absorption of water by the plant due to the high osmosis of soil water. There are many ways to reduce the salt stress in the growth of fruit plants, the most important of which is adding organic fertilizers such as humic acid or spraying with the amino acid proline.
High salinity in the root zone affects the growth of many plant species. soil salinity can lead to reduced emergence and low growth of seedlings. The objective of this study was to evaluate the growth of banana passion fruit (P. tripartita var. mollissima (Kunth) L. H. Bailey) seedlings under saline stress. The salinity effect on growth and dry matter (DM) production of banana passionfruit seedlings was evaluated under greenhouse conditions at Tunja / Colombia. Plantlets were grown in plastic bags filled with soil and 0; 20; 40 and 80mM NaCl were added to the soil, which induced the following different electrical conductivity levels: 0.70; 2.38; 3.47 and 5.49 ds m -1 respectively. salt was added gradually to the soil, up to the mentioned concentration. Results indicate significant differences among treatments. Plants of the control treatment without salt had higher number of leaves, total stem + shoot length, specific leaf weight, leaf area and DM in relation to salt treated plants. Leaf area and DM production were drastically reduced by salinity, especially by 80mM NaCl. The DM partitioning was also affected by salinity, reducing dry matter accumulation in leaves and increasing the DM in petioles + stems + shoots and roots. The findings from the study indicate that banana passionfruit seedlings are moderately sensitive to salt stress.
The increase in the concentration of salts in the soil has caused reduction in the growth of the plants because these ions cause, among other negative effects, changes in the ability of plants to absorb water. So, the objective of this paper was to evaluate the influence of salinity on the development of seedlings of yellow passion fruit (Passiflora eduli f. flavicarpa Deg). They were used vessels with a capacity to 2.9 dm ³ and five levels of salinity: control = 0,42dS/m -2,0 -4,0 -6,0 and 8dS/m. The results have showed that the total dry matter, dry matter of the aerial part and number of leaves have showed some significant differences among treatments. Thus, the higher the Saline lower, the absorption of water and nutrients and carbon accumulation into yellow passion fruit seedlings.
Growth and dry matter of pitombeira seedlings under salinity levels and application of biofertilizer
Comunicata Scientiae
Pitombeira is a native fruit tree from Amazon and is exploited in an extractive way. Currently, there is no commercial cultivation of this crop since there are no technologies for cultivation, propagation methods, fertilization and irrigation. In this context, the aim of this study was to evaluate growth and dry matter of pitombeira seedlings (Talisia esculenta (A. St.-Hill.) Radlk.) under salinity levels with or without bovine biofertilizer. The experiment was performed in a nursery at the State University of Paraíba (UEPB), Campus IV, in Catolé do Rocha, Paraíba, from September to December 2015. It was adopted a completely randomized design (CRD) with 10 treatments and 4 repetitions, in factorial arrangement 5 x 2, corresponding to 5 salinity levels: (0,8; 2; 4; 6 e 8 dS m-1) with or without bovine biofertilization. Plant height, stem diameter, number of leaves, leaf area, total leaf area, Dickson quality index, dry mass of root, stem, leaf and the whole plant were analyzed. The i...

2 Growing tomatoes using saline water and in soils with poor nutrient contents is challenging. The objectives of this work were to: (i) examine the yield and quality of tomatoes (Lycopersicon esculentum L.) irrigated with different saline water [electrical conductivity (ECi) = 3, 6 and 9 dS m −1 ]; and (ii) study the effect of fertilizer: inorganic, organic, and a mixed of both on tomatoes grown under saline conditions. Fruit weight and quality attributes including size, color, soluble solids, acidity, EC, and pH were measured. Growing tomatoes under 3 and 6 dS m −1 produced the highest yield, whereas irrigating with 9 dS m −1 reduced yield. The mixed fertilizer slightly ameliorated the yield reduction caused by salinity. Using organic fertilizer alone produced the lowest fruit yield. Fruit quality was more affected by salinity than fertilizer. The best growing conditions for tomatoes were in plots irrigated with 6 dS m −1 water under mixed fertilizer treatment.
The Biofertilizer Production for Salinity Stress in Plants: A Review
Agricultural Reviews
Biotic and abiotic factors are environmental factors that play a vital role in plant growth and productivity. Abiotic stress like drought, salinity environmental pollution has done major damage to the productivity of crops. According to the study by the United Nations Environment Program approximately 20% of agricultural land and 50% of cropland in the world is under the salt-stress. Salinization of soil converts agricultural land to barren land. There is an estimate that every year 1-2% decrease in agricultural land. Salinity affects plant photosynthesis, protein synthesis, lipid metabolism. The growing population in the whole world demands a simple low-cost method to reduce the effect of salinity on lands. The tremendous use of chemical fertilizers has created environmental problems such as deterioration of soil quality and surface as well as groundwater quality. Reduced biodiversity and suppressed ecosystem function are side effects of using chemical fertilizers. Thus, to overcom...
