Agroecosystem in cocoa plant was once of the important thing that have to manage intend to make the cacao plantation sustain. Cocoa was the mascot of industrial plant trade in Bali Province including in Tabanan Regency. Cocoa cultivation is almost done by most plantation farmers in Bali. The Bali Government, through the Tabanan Food and Agriculture Office, strongly supports the spread of cocoa cultivation. In 2010, a free seedling assistance policy for farmers was issued in order to obtain uniformity of growth and yield of cocoa plants. The types of cocoa cultivated by farmers vary, so that since 2015 there have been stunting and of cocoa pod rot (CPB). Several studies on cocoa have been carried out, but they have not been able to provide solutions to disease attacks, especially cocoa pod rot. In this regard, this study was conducted to provide solutions in terms of cocoa crop management in order to know how to reduce the percentage of damage to cocoa plants and determine the strategies to manage the Cocoa plant in field.  This research shows that the best strategy to reduce the pod rot in cocoa plant is pruning the branch of cocoa. The pruning activity is useful to make the area of cocoa plant well maintained and clean.

Trading frequency can be said as the implementation from trader of commerce. This case based on positive or negative trader reaction given by trader information.  Stock trading in BEI always fluctuate with price of volume value and frequency particularly. Frequency itself shows the company  involved or not. In trading frequency, if the indicator frequency it self shown the higher point, it means better. In spite of the most important thing is how the fluctuation or value conversion itself. On the frequencies we also could see which stocks is interested by the investor. When trading frequency high, it  may be create sense of interest from investors.The aim of this research, in order to know how far the effect of trading frequency (X) with stock value (Y) using cover stock value. The information used is begin 2008 with sample from twelve property and real estate companies. According to the research can be conclude from twelve companies in Indonesia Stock Exchange in 2008, 75 % of trading frequency samples doesn’t have signification degree between trading frequency and stock value. This case can be explained count on smaller than t tableEvaluation of this research is the trading measuring frequency at property sector and real estate not influence to stock priceKeywords : Trading Frequency, Stock Price

Many benefits ofTrichodermainoculation for improving crop production have been documented, including growth and yield enhancement and the alleviation of biotic and abiotic stresses. However, because rice is usually cultivated under continuous flooding that creates anaerobic soil conditions, this limits the benefits of these beneficial fungi. Cultivating rice with the methods of the System of Rice Intensification (SRI) provides rice plants with a more favorable environment for their colonization by beneficial microbes in the soil because the soil is more aerobic under SRI management and contains more organic matter. This study evaluated the effects ofTrichodermainoculation of rice plants under SRI management compared with transplanted and flooded rice plants, considering also the effects of different means of fertilization and different varieties in rice. Experiments were conducted in 2015 and 2016 under the tropical climate of Nepal’s western terai (plains) during both the rainy season (July to November) and the dry season (March to July). The results indicated significantly better performance (P = 0.01) associated withTrichodermainoculation for both seasons and for both systems of crop management in terms of grain yield and other growth-contributing factors, compared to non-inoculated rice cropping. Relatively higher effects on grain yield were recorded also with organic compared to inorganic fertilization; for unimproved (heirloom) varieties compared with improved varieties; and from SRI vs. conventional flooded crop management. The yield increase withTrichodermatreatments across all trials was 31% higher than in untreated plots (4.9 vs 4.5 mt ha−1). WithTrichodermatreatment, yields compared with non-treated plots were 24% higher with organic SRI (6.38 vs 5.13 mt ha−1) and 52% higher with non-organic SRI (6.38 vs 3.53 mt ha−1). With regard to varietal differences, under SRI managementTrichodermainoculation of the improved variety Sukhadhan-3 led to 26% higher yield (6.35 vs 5.04 mt ha−1), and with the heirloom variety Tilkidhan, yield was 41% higher (6.29 vs 4.45 mt ha−1). Economic analysis indicated that expanding the organic cultivation of local landraces under SRI management should be profitable for farmers where such rice has a good market price due to its premium quality and high demand and when SRI enhances yield. These varieties’ present low yields can be significantly increased by integratingTrichodermabio-inoculation with SRI cultural methods. Other recent research has shown that such inoculation can be managed profitably by farmers themselves.

Abstract This chapter discusses planting-seed quality, variety selection, plant population, planting date and row spacing. The goal of crop management is to create the perfect environment for the growth of the crop, where the perfect environment is characterized by the absence of stress or other factors that reduce crop growth and yield. This goal may be impossible or uneconomical to achieve, but that does not detract from its usefulness as a goal. The management practices discussed in this chapter are fundamental components of grain production systems that contribute to reaching the goal of the perfect environment. There are many management options available to an individual producer; selecting the best combination is not always easy and it may be constrained by factors outside the realm of the physiological processes controlling crop yield.

Commercial hop (Humulus lupulus L.) production occurs predominantly in temperate climates. The objectives of this study were to characterize the phenology of hops under subtropical climatic conditions and to determine the growth and yield potential. Two field experiments were conducted in Florida, southeastern United States. Rhizomes were planted in April. Data were collected during the establishment year. In the first experiment, we evaluated 7 American, 5 European, and 1 Japanese cultivars in a randomized complete block design. Bine height, main bine number, lateral shoot number, and dry cone yield (10% moisture) were recorded. Yield varied considerably, ranging from 0 to 197 kg ha–1. The top three yielding cultivars were ‘Cascade’, ‘CTZ’, and ‘Nugget’, all of which were American cultivars. Yield had positive correlations with main bine number and lateral shoot number, but it had no significant correlation with bine height. In the second experiment, we determined the duration of each phenological stage in ‘Cascade’. Reproductive phenology was characterized by premature and nonsynchronous flowering. Prolonged flowering resulted in multiple harvests over 61 days, starting in mid-June. We also evaluated crop management treatments, which consisted of three levels of hill spacing (76, 91, and 107 cm) and two nitrogen (N) rates (109 and 130 kg ha–1) in a factorial combination. Treatments were arranged in a split-plot design with hill spacing as the main-plot factor. Yield on a per-area basis increased with reducing hill spacing and increasing N rate by 41% and 38%, respectively. Our results demonstrate unique reproductive phenology of hops under subtropical climatic conditions, which prevents once-overharvest but enables the off-season supply of fresh hops over an extended period. This study provides a benchmark to develop production strategies for hops suitable to subtropical climates.

This study aims to see (1) Know how to read waria in the community (2) To see how public acceptance of waria is. The type of research used is descriptive qualitative which describes the adaptation of the transgender community by taking the location in Pa'doang-doangan Village, Pangkajene District, Pangkep Regency. Information retrieval was carried out by purposive sampling, and obtained 14 people. The data techniques used were observation, interview and documentation. The results showed that 1) The adaptation process carried out by the transgender community in Pa`doang-doangan Village is by associating and always interacting with the community and how they uphold the values of mutual respect for each individual both in a young or adult environment and the most important thing is to keep them ethical. In addition, they provide the best service to each of their customers and are active in community social activities so as to create a high emotional sense with community members. 2) The existence of transgender women in society at first received social pressures but slowly they were able to accept it well in society. The manifestation of the acceptance of the existence of the waria community in Pa`doang-doangan Village is that they are not only accepted in their social environment, but they get legitimacy from the local government. Now they have the same social role in their social environment.

In the present scenario images have become the most suitable way to keep our past alive. Nowadays people are very busy in earning their livelihood and day to day life, even though they want to keep their golden moment alive for the rest of life. Images have touched almost all the fields like medical, sports, social networking and many more. It is the need of time to know how the images are being captured and stored into memory. To deal with images and before analyzing them the most important thing is to capture the image. This is called as Image Acquisition. Image Acquisition is achieved by suitable camera. We use different cameras for different application. If we need an X-Ray image, we use a camera (film) which is sensitive to XRays. If we want Infra Red image, we use cameras which are sensitive to Infra Red radiations. For normal images (family pictures etc.) we use cameras which are sensitive to visual spectrum.

Background: Legumes are relatively cheap, non-animal good source of valuable proteins, micro-nutrients and vitamins in human and animal nutrition for many years. Recognizing the potential of legumes in achieving the sustainable solution to the global food security, protein access, eradicate hunger and malnutrition, FAO of the United Nations (The Food and Agriculture Organization), facilitated 2016 as the International Year of Pulses (grain legumes) under the banner ‘nutritious seeds for a sustainable future’. The nutrient, nitrogen and biological nitrogen fixation is very crucial for legume’s growth, besides sulphur deficiency is very sensitive to the nodulation and nitrogen fixation. Despite the amazing beneficial properties, legumes are neglected by most of us due to having tough competition with low price and high yielding cereal varieties. Methods: Therefore keeping in mind the above points, this review discusses the importance and application of legumes in different perspectives, legume cultivation patterns, importance of sulphur nutrition to legumes, role of sulphur oxidizing bacteria in sulphur nutrition, improving soil and environment, challenges and future of legumes. Conclusion: Legumes have variety of applications including food, health, environment and many other sectors but we are not able to produce enough amount according to their genetic potential due to inefficient breeding programs. Sulphur is an important nutrient along with N effecting its growth and yield. Sulphur oxidizing bacteria (SOB) have been proved as an important tool for improving yield and symbiotic nitrogen fixation in legumes. Therefor application of biofertilizers along with SOB and improved genetic breeding programmes may prove leading steps to enhance their production.

Influences of a hairy vetch cover crop and residual herbicides were examined in field corn in 1991 and 1992. Hairy vetch was seeded in mid-August and killed the following May with tillage, mowing, or glyphosate plus 2,4-D (no-till). These cover crop management systems were compared with a no-cover treatment. Residual herbicides including atrazine plus metolachlor applied PRE at three rates and nicosulfuron plus thifensulfuron applied POST at a single rate were compared within cover crop management systems. All cover crop management systems effectively controlled hairy vetch except mowing in 1992. The corn population was reduced in mow treatments containing uncontrolled vetch. Hairy vetch mulch suppressed some weeds in the no-till treatments in 1991, but more annual grass was noted late in the season with no-till into hairy vetch than with the no-cover treatments in 1992. Residual herbicide performance was similar across cover crop management systems, except for fall panicum control which decreased in some no-till systems. Unlike soil-applied herbicides, performance of POST herbicides was unaffected by cover crop management systems.
