AIt is a huge challenge for farmers worldwide to successfully increase the organic matter content of their soils and improve their water balance at the same time. Therefore, the main aim of the study is to develop and test organic-based nutrient composite materials that can be successfully used by farmers to increase soil organic matter content, improve water management parameters and implement water-efficient technologies. The study was performed in the orchard of the Institute of Horticultural Science of the University of Debrecen in Hungary (Debrecen-Pallag). The experiment was set up in a ten-year-old apple (Malus domestica ‘Pinova’) orchard. In the trial, fermented poultry manure and superabsorbent polymers (SAP) were used at different doses to study their effects on soil properties and fruit quality. Applied composite materials increased the nitrate and organic nitrogen content of the soil. Treatments did not affect the sugar content of the fruits but significantly and positiv...
Effect of Bio-Fertilizers and Organic Manures on Growth, Yield and Fruit Quality of Fruit Crops
2020
The major problem that occurs in developing countries is poor plant growth and yield due to soil infertility. Now-a-days to increase the crop production the fertilizers or pesticides used by the farmers in excess, which usually contain high amounts of chemicals, results in poor health of soil. In agriculture, use of inorganic compounds in high quantities has an impact on the sustainability of crop production, which consequently increases cultivation cost and decreases the productivity. The use of inorganic/chemical fertilizers, especially urea to the farming land lead to soil health reduced. Our farming has switched nowa-days to old age activities such as conservation agriculture. Bio-fertilizer, in general, is organic in nature and involves living organisms that synthesize the nitrogen in the atmosphere or create an environment that is useful to plants in the land or medium (in which the species are kept). On the other hand, the cost of bio-fertilizers is low and it has no adverse ...
The effect of bio and liquid organic fertilizer on weight and quality of apple
2014
This research aimed to analyse the effect of biopesticide and organic liquid fertilizer on weight and quality of apple. The study was carried out in Bumiaji, Batu, East Java (805'S, 11280'E, 1400 m in altitude) on July December 2013. The liquid organic fertilizer (LOF) was produced from water mixed with nitrogen source such as manure, urin, legume leaves, phosphoric powder and an energy source such as molasses or sugar juice This mixture was fermented with local microorganism. Biopesticide was extracted from Mahogany seed powder and Sour sop leaves and mix with LOF to get a combination (CB) treatment. Two treatments and a control were applied in different fields. First treatment consisted of application of the liquid organic fertilizer (LOF), while the second consisted of combination of the liquid organic fertilizer and biopesticide (CB). Five trees were selected per field for data collection. Application of LOF and CB were conducted every two weeks untill fruit harvest. C...
THE EFFECTS OF ORGANIC FERTILIZERS ON PERFORMANCE OF 'TOPAZ' APPLE IN ORGANIC GROWING SYSTEMS
I International Symposium on Organic Apple and Pear, 2007
The trial was conducted over two years in a 'Topaz'/M9 orchard (4000 trees/ha) using a randomized block design comprised of five fertilization treatments: 400 kg/ha Compo Guano (11% N), 880 kg/ha Maltaflor Special (5% N), 880 kg/ha Agrovit (5% N), 550 kg/ha Biosol (8% N) and an unfertilized control, and two types of orchard floor management: tree row clean-cultivated and grass within the tree row mowed. The treatments began in the third year after orchard establishment. Trunk cross sectional area (TCSA), the number of flower clusters per tree, fruit set, yield and average fruit weight were determined. The tree growth (TCSA increment) was significantly higher following treatments with Maltaflor Special and Agrovit than with Biosol. The cumulative yield per tree was higher following application of Agrovit than Biosol or Maltaflor Special, but no treatments significantly increased cumulative yield compared with the control. No significant differences were found for growth, yield and external fruit quality parameters for the other fertilizers and vegetation management methods, compared with the control.
The present study was conducted to compare the effects of natural and chemical farming system of apple production on soil, leaf nutrient status and fruit quality. Experiment was conducted in ten commercial apple orchards; five under natural farming system of apple production and adjacent to them, five were under chemical farming system of apple production for comparison. Leaf nutrient status, soil physio-chemical properties and fruit quality under both the farming systems were evaluated. The results indicated significant difference in the primary (N, P, K) and secondary (Ca, Mg) macronutrient status of leaf and soil samples collected from the study orchards (p < 0.05). Among micronutrients, status of Cu and Zn were recorded to be significantly different in both the farming systems whereas, Fe and Mn were recorded to be non-significant. Soil pH and EC were recorded to be higher (6.12, 0.48 dS m− 1) in CFS than NFS (5.77, 0.38 dS m− 1), while OC was reported to be higher (2.03%) in...
Current Trends in Natural Sciences
The present paper studied the influence of organic biostimulators and fertilizers, administrated in three applications between 70-75 BBCH, on growth and fruiting processes of three apple cultivars grown in five and six years high-density orchards at the Research Institute for Fruit Growing, Maracineni, Arges (southern part of Romania). During 2020-2021, the increase of the trunk cross-sectional area registered an average of 5.25 cm2 (0.02-21.19 cm2), and the fruit yield averaged 55.64 t/ha (0-166.98 t/ha). The mean values recorded for the fruit weight and pulp firmness, were 173.22 g (74.13-558.76) and 76.50 units Bareiss HPE-II-FFF (53.60-89.10), while the pH of the fruit juice and total soluble solids fluctuated around 3.55 (3.09-4.68) and 13.3 ⁰Brix (9.45-18.20). Foliar treatment with Cifamin BK (1.5 l/plant) significantly increased fruit yield by 49.5% compared to the untreated variant. Fruit weight increased in all three fertilization treatments on ´Decosta Jonagold de Coster´ ...

The number of fruits per bunch and nutritional quality of the fruits are important horticultural and breeding selection indices in Musa improvement programs. Three plantain hybrids ('30456-3', 'PITA 14' and '29525') and a landrace genotype, 'Agbagba', were evaluated for response to organic and inorganic fertilizers in a 4 x 3 factorial in a randomized complete block design (RCBD) in triplicate. Fruit parameters measured were fruit weight, edible proportion and pulp dry matter content; also, the concentrations of nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), iron (Fe) and zinc (Zn) in fruits were determined. These parameters were measured in two cropping cycles, the plant and ratoon crops, respectively. The hybrid, '29252' had the highest pulp N, K, Ca, Fe and Zn concentrations in the plant crop. In the ratoon crop, N and P were highest in '29525' and '30456-3', while the concentrations of the other nutrients did not differ among the genotypes. The landrace, 'Agbagba', produced the heaviest fruits, accumulated the highest pulp dry matter and fresh edible proportion in both crop cycles. Although in the plant crop, the fertilizer treatment did not affect most of the pulp nutrient concentrations, the P concentration decreased by 14.29 and 118.18%, respectively when inorganic fertilizer and poultry manure was applied. The N, K and Zn concentrations, respectively, increased by 6.45, 14.55 and 62.50% with inorganic fertilizer application, while all the nutrient concentrations were lowest when no fertilizer was applied. The fresh fruit weight, pulp dry matter content and fresh edible proportion were highest when poultry manure was applied.
Plant nutritional and environmental aspects of organic apple production in East Hungary
Ecocycles, 2017
The recent surge in interest in fruit growing without the use of agrochemicals in order to safeguard environmental and human health has led to increased awareness of organic fruit production (OFP). Despite the widespread use of the method, there is little information on its nutritional aspects, especially in Hungary. Therefore, the aim of this three-year study was to investigate the nutrient status in an organic apple management system and the impact of nutrient applications on nutrient uptake and on the environment. The research was undertaken at the orchard Fruit Research Station of the University of Debrecen in Debrecen-Pallag, Hungary, during 2009-2011. Three cultivars ('Reanda', 'Rewena', and 'Retina') were selected for the study. In the plantation, only organic manure was applied (stable manure, 30 t ha-1 , in 2007). The effect of organic methods was monitored by soil and leaf analyses, as well as field observations. Leaf analysis results indicated significantly lower N, K, Mn, Cu and Zn content in cultivar 'Retina' than in 'Reanda' and 'Rewena'. Results suggested that mobility and availability were unbalanced and obstructed, especially in the case of Ca. The study also demonstrated that the lower nutrient content of soil and also the generally poorer uptake of Ca and Zn in organic apple orchards resulted in higher production risks as compared with conventional or integrated ones. We conclude that a more balanced and more efficient nutrient supply system is needed for organic farms in order to achieve good quality and profitable yield.
Agronomic Traits and Fruit Quality of Pineapple with Different Levels of Chicken Manure Application
Silpakorn University Science and Technology Journal, 2014
The responses of the pineapple (Ananas comosus (L.) Merr cv. Pattavia) grown in a fine-silty soil to various levels of chicken manure, in terms of plant growth, and fruit yield and quality, were investigated at a farm plantation in Petchaburi, Thailand. A randomized complete block design with 4 replications was used. Treatments were the chicken manure applied in levels equivalent to 0 (control), 3, 6 and 9 g nitrogen (N) plant-1. The manure was manually and thoroughly mixed with the soils, which was incubated for 30 days prior to pineapple planting. Agronomic traits of the pineapple plants and chemical composition of the pineapple fruits were determined. Plant growth and fruit size were linearly increased (p<0.05) with the increased manure levels. Fresh fruit weight from the highest level of manure application was 60% higher than that of the control treatment. Similarly, citric acid and vitamin C contents were linearly increased (p<0.05) as the manure rates increased. It can be concluded that growth and yield of the pineapple positively respond to increased chicken manure application. In terms of productivity, the moderate application rate of chicken manure cannot yet be recommended because curvilinear response has not been detected in this study. Therefore, further study with respect to a wider range of application rate is required to find out the most appropriate rate.
Effect of organic manure on soil physicochemical properties under fruit based agroforestry system.
An experiment was conducted under peach based agroforestry system for two consecutive years during 2010 and 2011 in experimental farm of Department of Fruit Science, Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh. The experiment was laid out in Randomized Block Design with three replications and comprised of 10 treatments, which included three different doses of Vermicompost (2t/ha, 4t/ha, 6t/ha) and three different doses of FYM (15t/ha, 20t/ha, 25t/ha) in combination with and without Peach. The results reveled that soil pH was the highest (7.41) under peach where, FYM @ 25t/ha was applied as compared to other doses of organic manures. Soil electrical conductivity was recorded maximum (0.28 dSm-1) under 6t/ha vermicompost, while soil bulk density was the minimum (1.02 Mg m-3) under 25t/ha FYM. Soil organic carbon content at 0-15cm and 15-30cm soil depth was recorded higher 2.16% and 1.75% respectively, under higher dose of FYM (25t/ha) as compared to other doses of organic manures. Available macronutrients were significantly affected by the intercropping of medicinal herbs and the application of organic manures under peach based agroforestry system. Soil nitrogen, phosphorous, sulphur and magnesium were found maximum under peach where, 6t/ha vermicompost were applied as organic manure, while soil potassium were recorded higher where, 25t/ha FYM were applied. The physicochemical properties and nutrient status of soil were comparatively better under peach than in the control.
