The role of biofertilizers in improving vegetative growth, yield and fruit quality of apple

Abstract

Apple trees which grafted on M.M. 106 stocks were planted at the beginning of spring 2014 in pots at the Research Institute of Horticulture in Skierniewice, Poland. The used treatments in the experiment were: NPK fertilization and bioproducts: Fertigo (Manure), Micosat, Humus UP, Humus Active + Aktywit PM, BioFeed Quality, BioFeed Amin, Vinassa, Florovit Natura and Florovit Eko. In the spring, these treatments were applied to apple trees alone or enriched with Pantoea sp., Pseudomonas fluorescens, Klebsiella oxytoca and Rhizobium sp. bacterial strains. Growth, yield and fruit quality parameters were evaluated. The results revealed that photosynthetic rate was greatly improved by the addition of bacteria to Fertigo (Manure), Micosat, Humus UP and Humus Active + Aktywit PM as compared to NPK. Tree trunk thickness was significantly enhanced with Vinassa, Florovit Natura and Florovit Eko enriched with bacteria. The application of bacterial strains increased the effectiveness of Fertigo (Manure), Humus UP, Humus Active + Aktywit PM, Biofeed Amin and Yeast in increasing significantly number and weight of fruits as compared to NPK.

Effectiveness of indigenous endomycorrhizal biofertilizer prototype on organic salak (Salacca zalacca) plantations and its effect on nutrient and carbohydrate content of leaves

“…The administration of indigenous endomycorrhizae resulted in the absorption of nutrients and water through the endomycorrhizae structure that enlarges the surface area of salak root, so that the plant roots can absorb the nutrients and water (Baslam et Thus, a correlation between indigenous endomycorrhizae biofertilizers prototype and salak trees can be suspected, which increases the yield, the quality of the yield, and the physiological processes of salak trees. The results of this efficiency test are in accordance with those of previous studies wherein endomycorrhizal fungi biofertilizer can increase the growth, production and quality of pineapple yield (Nurhandayani et al 2013), chill (Tanwar et al 2013), teak (Proborini, 2013), tea (Nepaleon et al 2012) and apple (Fediala et al 2018). Endomycorrhizae plays a role in increasing plant resistance to drought or lack of water in the dry season because the root of the plants possess mycelium that can reach water in the wider rhizosphere area of the soil and adsorb water despite h t e d availabihty .…”

The Role of Nanozeolite and Biocapsule in Improving Growth, Yield and Fruit Quality of Low Chilling Apple (Malus × domestica Borkh.) Cv. HRMN-99 in Prayagraj Agro-Climatic Condition

“…Biocapsules and nanoziolite with combination of NPK enhanced the reproductive growth that's why this type of result has to be seen. These results are in support with Verma et al [11] and Fediala et al [10].…”

Potential Use of Beneficial Microorganisms for Soil Amelioration, Phytopathogen Biocontrol, and Sustainable Crop Production in Smallholder Agroecosystems

“…Modern farming encourages the integration of bio-inoculants with other farm management practices and this has been shown to have complementary and synergistic effects in improving growth and yield quality characteristics in apple fruit farming (Mosa et al, 2018). The positive association between agronomic management practices and ecosystem functioning could be exploited to enhance soil fertility amelioration and plant productivity (Costanzo and Bàrberi, 2014).…”

“…Additional methods efficient in augmenting indigenous soil PGPMs can be integrated to enhance microbial bio-functionality. These include the use of organic amendments such as farmyard manure and vermicompost (Mosa et al, 2018;Koskey et al, 2020), biotechnological approaches such as plant breeding (Bakker et al, 2012), crop management practices such as agroforestry, rotation, intercropping, cover cropping, and practicing reduced soil disturbance (Ventorino et al, 2012;Hontoria et al, 2019;Elagib and Al-Saidi, 2020).…”
