Efforts to Produce Siamese Citrus Fruit Out of Season and Fruit Quality Improvement Through Application of Potassium Nitrate and Agrodyke Fertilizer

The research aimed to find out the efforts to produce off-season orange fruit and increase the quality of fruit through the application of potassium nitrate and agrodyke organic fertilizer. The study used a factorial randomized block design with 2 treatment factors. The first factor is the flower induction application using potassium nitrate (K) consisting of 3 levels, namely (K0 = 0 g/tree), (K1 = 20 g/tree), and (K2 = 40 g/tree). While the second factor is the application of agrodyke organic fertilizer (P) consisting of 4 levels, namely (P0 = 0 g / tree), (P1 = 15 g/tree), (P2 = 30 g / tree) and (P3 = 45 g/tree). There are 12 combination treatments and each of them is repeated 3 times so that 36 tree plants are needed. The results showed the interaction between potassium nitrate treatment with agrodyke organic fertilizer treatment had no significant effect on all observed variables. Potassium nitrate treatment and agrodyke organic fertilizer can significantly improve the quality of orange citrus fruit out of season physically. In the treatment of potassium nitrate 40 g/tree, the weight of the harvested fruit per tree was obtained, the weight per fruit and the highest fruit diameter were 13703.90 g; 99.92 g and 6.81 cm or an increase of 62.24%; 16.32% and 9.49% compared with no treatment of potassium nitrate which is 8446.60 g; 87, 42 g and 6.22 cm

Identification of Development Phases and Changes Shoots Flowering Orange Siam Plants

Citrus is a tropical fruit that is preferred by the majority of the Indonesian people. But availability does not comply with this requirement due to the increase of population, income generation, public awareness of the importance of nutrition in addition to the development of agro-industries This is because one of them is the presence of buds induced and not induced in which to manipulate flowering citrus crop is still relatively difficult, because information limited to flowering as the flowering phase and an endogenous substance which causes the flowers induced or not induced. This study uses the citrus crop was ten years old, aims to identify phases-phase of the development of flowers and learn the changes in endogenous substances suspected to affect flowering buds flowering shoots induced or not induced. The results showed that the flowering buds induced marked by enlargement and swelling at the base of prospective new shoots, while the buds are not induced longitudinal prospective new shoots grow straight, and do not experience enlargement and swelling at the base Citrus plants flower development consists of four phases

Flower Position on Main Stem and Branches Affect Fruit Set in Citrus Plant (Nobillis Var, Microcarpa L)

The aim  of the research  is to  find  out  best  citrus  flower  position  (shot  tips or axillary shoot) in relation to fruit formation ‘Seam\u27 citrus. The research was done on Citrus which belongis to the farmer at Catur village, district Kintamani, Bangli Regency, Bali. The research was conducted from May 2014 -April 2015. Ten years old Citrus plants were used in this study.  Five Plants were chosen.  Flower  development  and  fruit  formation  were observed  on six  different  positions on  the  plant,  i.e. main stem: lower  part, middle  part  and an upperpart, and  branch which include lower axillary part of the branches, middle axillary branch and on the tips. Variable observed were a number of flowers developed, both in main stem and branches during on-season and off-season flowering time. Another observation was a number of fruits developed on each position. Results show that flower best on lower axillary branches, both during on-season (54,16%)the base and off-season (45,02%). Flower developed on the tips were much lower, bot on-season (6,90%) and off-season (12,50%). The highest number of fruits was also achieved attheloweraxillary branch during on-season (52,23 %) and off-season (35,27 %

Flower Growth Position Determines with Formation of Fruit-set on Citrus Siam Plants

The purpose of this study was to find out the position of the emergence of flowers associated with the formation of fruit-set as a potential fruit on the citrus Siam plant. This study used a randomized block design with two factors observed that is flower position on the branch and flowering period. The results of the statistic data tabulation show that. The interaction between the positions of the flowering period on citrus Siam plants is not significantly different. The position of the emergence of the flower determines many fruit-set are formed. Top branch. The position of the top branch shows the percentage of fruit-set is formed more that is 97,95 %  and the lowest in rootstock, that is 91,30. This incident was supported by more interest formed when the top branch that's is 224,95 florets more 53,65 % if it is stretched in the lower stem position 104,27 florets. This is supported by  relative water content, chlorophyll,  N, P, K and sucrose leaves i.e. 46,78 %, 28,82 %, 1,40 %, 0,74 %, 3,42 % and 3,42 % bigger than the lower stem i.e. 41,36 %, 18,64 %, 1,16 %, 0,19 %, and 2,17 %

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

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 ZnSO4 micro fertilizer dosage. This experiment was arranged as a randomized block design consisted of 2 factors.  The first factor was mycorrhizal inoculant (0, 50, 100 and 150 g/tree), while the second factor was the dosage of ZnSO4 micro fertilizer (0, 5, 10 g/tree). All treatments were repeated 3 times. The results showed that the interaction between mycorrhizal inoculant treatment and ZnSO4 micro fertilizer dosage did not significantly affect all of the variables observed.  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
