The purpose of this study was to determine the potential of agro-climate, technology of cultivation, harvest and postharvest chrysanthemums. This study uses survey method, through the collection of primary data and secondary data. This research is located in the village of Pancasari, District Sukasada, Buleleng Bali Province. Descriptive survey conducted on 40 respondents chrysanthemum growers using the component identification of determinants of commodity production chrysanthemum include: site selection, infrastructure, crop production processes and post-harvest handling. The survey results showed that 100% of the farmers have chosen a suitable location with agro-climatic conditions required by the chrysanthemum plant, and 86.09% of the farmers have been using the means needed to support the process of crop production. In the process of production of 78% in accordance with the operational procedures. At the stage of harvest and post-harvest handling 80% have been implemented by farmers and some still use conventional methods of handling. Thus Pancasari village has a potential location for the cultivation of chrysanthemum as a mainstay commodity.

Constraints that can affect the occurrence of induction and flowering development of Siamese citrus plants are endogenous and exogenous factors. Exogenous factors include microclimate. Microclimate, especially extreme humidity, is one of the factors that can determine the physiological process of flowering of Siamese citrus plants. Siam oranges require 6-9 wet months (rainy season) and 3-6 dry months (dry) and need enough water especially in July-August (dry season). The purpose of this study was to examine and determine the role of microclimate on the phenology of flowering Siam oranges in Badung, Bangli and Gianyar. The assessment method was observed in citrus centers from 2014 to August 2018. The results showed high rainfall occurring throughout 2014, a flowering phenology disorder that had previously flowered Siamese citrus plants 1 to 3 times a year to 4 to 6 times a year. The number of flowering periods is not supported by the number of flowers formed because the flower miscarried before the fruit-set formed, the height of the deciduous flower is supported by the large number of leaves formed at the location of the garden whose height is less than 1000 meters above sea level. Location of citrus orchards which applies an integrated management system to. New potentials are good for cultivating conjoined oranges, namely dry land or dry fields and sandy soil when compared to oranges planted in faddy fields.

The purpose of this study was to determine the effect between types of cuttings and between varieties of plant material on any type of plant material chrysanthemum cuttings. Methods trial with a randomized block design factorial nested pattern. The results showed that the treatment effect of plant cuttings type of material does not give a significant effect on all parameters observed. Influence of cuttings between varieties at any plant material gives a significant influence on the parameters, the maximum number of leaves, flower stalks weight and economical weight of fresh flowers. The average weight of the highest economical due to the influence between the varieties in each type of plant material cuttings from mother plants found in fiji white varieties 93.83 g and not significant with 93.46 g fiji yellow varieties. So also in effect between varieties on any type of cuttings from the plant material production plant gives the same result.

The growing period of fruit crops requires nutrients for growth and development; this is very important in the physiology of fruit crops. Durian plants in determining the fruit harvest are largely determined by the process of growth development in plants. Leaf budding age is the main factor determining nutrient nutrients status in durian plants (Durio zibethinus Murr.). Durian plants require sufficient nutrients to obtain growth and fruit harvest; leaf analysis can be used as a guide in diagnosing nutrient status and fertilizer recommendations on durian plants. However, standard leaf sampling techniques should be accurately determined. The purpose of this research is to study and to know the proper dosage of fertilizer for durian plants associated with vegetative growth phase of leaf buds after fruit harvest the study was conducted in three locations: Sudaji Village, Munduk Bestala Village, and Sinabun Village, Buleleng Regency, March-November 2016. The leaves in the proper period of use are used as guidelines for fertilization when leaves have the best correlation relationship with period development vegetative plants. Leaf samples are taken periodically after the fruit harvest durian plants. Starting the early shoot period until the dormant buds period, the results showed that the nutrient concentration of nitrogen in leaves decreased with the age of leaf buds, the concentration on the initial leaf buds was higher than the full leaf buds. The correlation of nitrogen concentration from the development of leaf buds of durian plants has different nutrient requirements between leaf buds development, i.e. early leaf buds, adult leaf buds and dormant leaf buds; the smallest value is obtained on the growth of dormant buds. With a correlation coefficient of 0.82 each. At the time the leaves are young, the leaves do a great activity and require a supply of nutrients, as well as organic and water in the process of physiology of growth and development of plants in relation, can produce optimum fruit harvest.

The aim of this research to get a picture of the prolific bud leaves, flowering in the framework of the formation of harvest fruit Siam. Shoots are produced from cultured vegetative vegetation, I e without going through a marriage process because it comes from one parent. The critical point of the formation of the fruit is largely determined by the flowering formation process. Environmental factors and nutritional and hormonal activity in the plant and environmental factors that influence flowering are a mineral nutrient balance, temperature, sunlight intensity and photoperiod. The study was conducted from March to November 2017, in Seming Village, Kerta District, Gianyar Regency of Bali Province. The research is descriptive so there is no special treatment given to the samples. The research is done by the descriptive method that is continuous research so that there is a thorough knowledge about the horticultural cultivation problem of tropical fruit, especially the citrus fruit so that the physiology science of flowering and flowering is obtained in relation get the fruit of the harvest. The citrus varieties used in this research are Siamese orange varieties that have been 6 years old. The number of samples observed as many as 10 plants with the observation of the shoot formation period with the observation once every two days, the percentage of leaf buds, the period of leaf buds, the number of buds that developed. The results showed that the cultivation of Siam plant experienced shoot growth period during one phase of growth 3 times in one period of growth. There are 4 stages of a period of replanting that is 1). Early budgets, 2), full repayment, 3) adult mating and 4) dormancy repayment. Description of flowering development process until the formation of blossom flowers there are 5 important stages traversed by citrus plants are: 1) flower induction, 2) initiation of flowers, 3) development of flower buds towards an thesis, 4) blooming flowers 5) pollination and conception. Siam citrus plants reach the stage of reproductive development, with some or all apical meristem shoots on the branches stop producing leaves and start forming the flower parts according to the typical sequence in the formation of broad flowers apical meristem gradually decreases as the flower parts are formed in sequence. The order of the formation of the flower parts on the citrus plant lasts from the inside out, starting from sepals. Petals, Keywords:Orange IntroductionSiam citrus plant (Citrus nobilis var, microcarpa Hasah) a type of fruit that continues to experience increased needs, because it is the most important fruit commodity in Indonesia after mango and banana. Citrus is very liked by the community, because it tastes sweet, tasty, fresh, and peel easily peeled, as well as a source of nutrients and sources of vitamin C. Citrus fruits are a complementary ingredients in supporting family nutrition The market opportunities of citrus fruit is still quite broad, because in addition to the nutritional value is also affordable, but t...
