W. Puger I. M. Nuriyasa <p style="text-align: justify;">The research was intended at increasing the productivity of Bali ducks through the utilization of fermented wine waste. The study used a <em>completely randomized design</em> <em>(CRD),</em> four treatment rations, and five replications. There were 40 experimental units. Each unit of experiment used five ducks. The total of ducks used was 100. The treatments imposed on ducks were ducks fed with no fermented wine (R0), containing 5% fermented wine (R1), containing 10% fermented wine (R2), containing 15% fermented wine (R3). The variables were examined namely performance, carcass, and digest coefficient. The results showed dietary consumption, final body weight, weight gain, and feed conversion did not show significant differences (P&gt;0.05) among treatments. The conclusion is the use of fermented grape wine waste up to 15% level not significantly affect the digestibility of rations, the performance, and carcass of male Bali ducks.</p> 2019-09-27T07:41:55+00:00 ##submission.copyrightStatement## Evaluation of post-harvest tomato practices (lycopersicum sculentum) 2019-11-13T15:39:03+00:00 Jimmy Cristhian Loor Jumps Gonzalo Rigoberto Menoscal Chilán Doris Marlene Sancán Murillo Alexander Patricio García Mendoza <p style="text-align: justify;">Despite the fact that tomato is the most cultivated vegetable in Portoviejo, there is still a need for change in the production farms with respect to the post-harvest handling of the product. The work shows an analysis of the results of inadequate post-harvest management of tomatoes, which was carried out as part of a research teaching work at the Paulo Emilio Macías Higher Technological Institute. The problem is centered on the lack of good post-harvest management practices for tomatoes on farms in the Portoviejo canton. The study was applied to 20 producers from 5 populations of rural Portovejenses, whose objective was to determine and quantify post-harvest losses, in the harvest-marketing phase, analyzing the decrease in the quality of the vegetable, due to handling factors, packaging, and transport conditions between farms and the commercialization center. The results obtained show that good post-harvest practices are not carried out and that the producers are unaware of the importance of proper management during collection, transport, and marketing, concluding that it is necessary to create a post-harvest management guide for the cultivation of tomato, to be applied in farms of the Portoviejo canton.</p> 2019-11-08T11:42:04+00:00 ##submission.copyrightStatement## Overcoming the failure of fruit-set and fruit drop of siam orange on off-season period through application of mycorrhizal inoculants and ZNSO4 micro fertilizer dosage 2019-11-13T15:39:02+00:00 Ni Komang Alit Astiari Ni Putu Anom Sulistiawati Ida Bagus Komang Mahardika I Nyoman Rai <p style="text-align: justify;">This research was carried out at Kintamani District, Bangli Regency, Bali-Indonesia, from February to October 2019 with aimed to overcome the failure of fruit-set and fruit drop of Siam orange on off-season period through application of mycorrhizal inoculants and ZnSO<sub>4</sub> micro fertilizer dosage. This experiment was arranged as a randomized block design consisted of 2 factors.&nbsp; The first factor was mycorrhizal inoculant (0, 50, 100 and 150 g/tree), while the second factor was the dosage of ZnSO<sub>4</sub> micro fertilizer (0, 5, 10 g/tree). All treatments were repeated 3 times. The results showed that the interaction between mycorrhizal inoculant treatment and ZnSO<sub>4</sub> micro fertilizer dosage did not significantly affect all of the variables observed.&nbsp; Mycorrhizal inoculant dose 150 g/tree could overcome the failure of fruit-set and fruit drop and improved the quantity and quality of fruit of Siam oranges on off-season, which was reflected by increased number of fruits harvest per tree (249,00 fruits), weight per fruit (106,10 g), weight of fruit harvested per tree (26,34 kg) and total dissolved solids (13.52% Brix), or increase 31,44%; 18,15%; 54,58%; and 35,74%, respectively, compared to without mycorrhizal inoculant i.e 189,44 fruit; 17,04 kg; 89,80 g and 9,96% Brix.</p> 2019-11-11T03:41:19+00:00 ##submission.copyrightStatement##
