The greenhouse research was conducted in the Agrotechnopark of the University of Brawijaya at Jatikerto Village, Kromengan Sub-District, Malang Regency. The utilized research method was Completely Randomized Nested Design consisting of two factors. The first factor was the concentration of nutrient solution consisting of 100 % (3.5 dS m-1), 75 % (2.6 dS m-1), and 50 % (1.8 dS m-1) concentrations. The second factor is the inoculation of biological agents consisting of no inoculation of biological agents, PGPR (Plant Growth Promoting Rhizobacteria), AMF (Arbuscular Mycorrhizal Fungi), and PGPR + AMF. The data were analyzed using an analysis of variance and continued with the test of Honest Significant Difference at 5 % level. The results showed that the interaction between the types of biological agents and nutrient concentrations significantly increased the number of flowers, number of fruits, fruit weight, fruit diameter, and sugar content of cherry tomatoes. The AMF application showed the highest fruit weight per plant and fruit diameter, especially at 100 % nutrient concentration. The AMF application also showed a higher sugar content compared to the control and PGPR but not significantly different from the PGPR + AMF treatment at all levels of given nutrient concentration. Fruit weight per plant with treatment of AMF, PGPR + AMF, and PGPR respectively produced 64.47, 48.75 and 29.39 % higher than without application of biological agents.","PeriodicalId":39205,"journal":{"name":"Journal of Applied Horticulture","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43523231","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to select the optimum water spray conditions and developmental stages of a flower for field applications, the influence of varying pressures of the power sprayer, nozzle diameters, and spray distances on flower and leaf bud thinning rate was investigated under four different developmental stages of flower such as bud sprouting, pink, balloon and flowering period using the water cut bearing branch of “Kawanakawase Hakuto” peach. The optimum conditions for the application of the pulsatory water spray gun were identified as a power sprayer pressure of 2 MPa at a nozzle diameter of 2 mm and spraying distance of 1 m in the ballooning and flowering stages. A flower bud thinning rate greater than 60 % and a leaf bud thinning rate lower than 7 % were observed under these conditions. In the field application test based on the selected conditions, the flower and leaf bud thinning rates were ideal for fruit production and showed higher fruit characteristics compared with fruits produced by a conventional fruit setting management method. In addition, the application of this system for flower thinning could considerably reduce the total work time compared with the conventional method. Hence, it is also expected that the newly developed system can be used for labor savings during fruit setting management in peach cultivation.","PeriodicalId":39205,"journal":{"name":"Journal of Applied Horticulture","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43159210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Essential oil content and its characteristics vary amongst the species and climatic factors play a major role. Essential oil, to be suitable for the specific commercial purpose should have basic characteristics. In the present study, extracted oil of selected three citrus species Citrus reticulata, C. maxima and C. jambhiri grown at different altitude of Sikkim Himalaya were characterized. The oil yield was up to 2.4 % in mature fruits and 2.5 % in immature fruits at an altitude of > 1600 m in mandarin orange with significant variations concerning species and altitude. The various analysed oil parameters and their highest values in the study are refractive index (1.49), specific gravity (0.87), free fatty acid (7.83 %), acid value (8.37 %), saponification (163.37 mg KOH / g of oil), iodine value (116 g I2/100 g), peroxide value (36.33 meq O2/ kg), thiocyanogen (77.29 %), ester value (57.63 mg KOH/g), phenol (81.92 mg/g). These parameters also showed variations with altitude and the species. The C. reticulata grown at higher altitude (> 1600 m from MSL) was found to have better essential oils than C. maxima and C. jambhiri with some exceptions. The characteristics highly endorsed the use of these essential oils for food and cosmetic industries. The waste management with simultaneous production of valuable compound is the major perspective sought in the study.","PeriodicalId":39205,"journal":{"name":"Journal of Applied Horticulture","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44836143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For a wider use of aquaponic systems increasing yields are inevitable. The aim of our research, started in 2017, was to eliminate the drawbacks of aquaponic systems using alternative solutions in order to remain in the framework of sustainable agriculture. In order to meet the above challenges, a hybrid, automated aquaponic system was installed in which the soil was not removed completely from the systems that are not completely closed as fish receive fresh water as well as keeping in this way hormones impeding growth at a low level. Crucians and African catfish were placed into two tanks of 7 m3. Further novelty of the system is the application of quail dung in a quantity determined specially for increasing the natural efficiency of the system. Three methods of cultivation were used and plant macroand micro-elements were measured. Results indicate that the system is suitable for growing different chilli types while quail dung input contributes to increase yield significantly therefore it can be integrated into aquaponic systems excellently.","PeriodicalId":39205,"journal":{"name":"Journal of Applied Horticulture","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48772820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Synthetic insecticides which are primarily used for its control, have various drawbacks. Bioactivity of Tephrosia vogelii, Tithonia diversifolia, Vernonia amygdalina and Phytolacca dodecandra aqueous extracts was evaluated against T. absoluta in laboratory. Leaflets with third instar larvae (3.85 5.65 mm) of T. absoluta in mines were collected from established tomato field. Aqueous plants extracts were evaluated at a dose of 10 % weight/volume. Sterile tap water and azadirachtin 0.03 % EC were used as negative and positive controls, respectively. Petri-dishes of 9 cm diameter (n=10) were used as bioassay arenas in a completely randomized design with four replications. Data on larval mortality were collected every 24 h for 5 days. Three bioassays were conducted on different dates. Results indicated that tested plant extracts exhibited a capacity to kill T. absoluta larvae in tomato leaf galleries with significant difference among them (P <0.0001). The killing capacity increased with exposure time. At 24 h of exposure, T. absoluta larvae mortality was in a range of 35.0 37.5 % for azadirachtin and 5.0 10.0 % for T. vogelii while all other aqueous extracts had 0.0 % mortality, except V. amygdalina which recorded 2.5 % in bioassay one. In all bioassays, the lowest mortality recorded 5 days after treatments with T. vogelii, T. diversifolia, V. amygdalina, P. dodecandra and azadirachtin was 32.2, 2.8. 2.5, 20.5 and 97.5 % while the highest mortality at this time was 35.1, 10.6, 13.3, 24.9 and 100 %, respectively.
