The Difference

ABSTRAK Bunga krisan (Chrysanthemum sp.) merupakan salah satu tanaman hias yang diproduksi sebagai bunga potong. Budidaya bunga krisan biasanya menggunakan metode  di guludan, namun saat ini sudah berkembang budidaya krisan menggunakan metode pot. Berkembangnya dua metode budidaya mengakibatkan adanya perbedaan kebutuhan air tanaman dan finansial pada masing-masing metode. Oleh karena itu perlu dilakukan penelitian untuk menganalisis kebutuhan air tanaman dan kelayakan finansial dari masing-masing metode. Tujuan penelitian ini adalah untuk: (1) menentukan perbedaan tingkat kebutuhan air pada budidaya bunga krisan menggunakan metode guludan  dan metode pot, dan (2) menganalisis kelayakan finansial budidaya tanaman krisan dengan kedua metode tersebut. Perlakuan penelitian ini adalah : Budidaya bunga krisan dengan metode guludan dan budidaya bunga krisan dengan metode pot. Pada masing-masing metode dianalisis kebutuhan air tanaman (ETc) dan kelayakan finansialnya. Analisis kelayakan finansial yang digunakan dalam penelitian ini adalah NPV, IRR dan BCR. Total kebutuhan air tanaman krisan dengan metode guludan dan pot masing-masing adalah 1056,72 ml/tanaman dan 866,64 ml/ tanaman, sedangkan rata-rata kebutuhan air harian masing-masing 19,57 ml/hari, dan 16,05 ml/hari. Hasil kelayakan finansial dari penelitian ini adalah NPV pada metode guludan sebanyak Rp. 5.687.537,35 lebih kecil dari metode pot yang bernilai Rp. 12.627.709,99. IRR dari metode guludan dengan persentase 15% lebih kecil dari metode pot yang persentasenya 18%. Analisis BCR dari metode guludan memperoleh hasil sebesar 1,51 yang mana lebih kecil dari metode pot yang memperoleh hasil sebesar 1,63. Walaupun kedua metode budidaya bunga krisan dikatakan layak, namun metode pot lebih menguntungakan  dari pada metode guludan dari segi finansial.   Kata kunci : kebutuhan air tanaman, analisis finansial, krisan. ABSTRACT   Chrysanthemum flower (Chrysanthemum sp.)  are one of the ornamental plants produced as cut flowers. Chrysanthemum cultivation usually uses the bund method, but nowadays chrysanthemum cultivation has develoved using the pot method. The development of two methods of cultivation resulted in differences in the plant water requirements and financial in each methods. Therefore it is necessary to conduct research to analyze the plant water requirement and the financial feasibility of each method. The purpose of this research are to : (1) determine the difference of water requirement level on the cultivation of chrysanthemum flower using the method of bund and pot, and (2) analyze the finance feasibility on cultivation of chrysanthemum flower with both methods. The treatment of this research are : cultivation of chrysanthemum flower with bund method and cultivation of chrysanthemum flower with pot method. In each method analyzed plant water requirements (ETc) and financial feasibility. The analysis of financial feasibility used in this research is NPV, IRR and BCR.  Total requirement of chrysanthemum flower water with bund and pot method are 1056,72 ml/plant and 866,64 ml/plant, while the average daily water requirement is 19,57 ml/day, and 16,05 ml/day. The financial feasibility result of this are NPV on bund method as much as Rp. 5.687.537,35 is smaller than the pot method which is worth Rp. 12.627.709,99. IRR from the bund method with percentage 15% smaller than pot method with the percentage of 18%. The BCR analysis of the bund method yields 1.51 which is smaller than the pot method which yields 1.63. although both methods of chrysanthemum flower cultivation are said to be feasible, but the pot method is more advantageous than the method of bunds in financial terms.

A study was conducted to assess the effect of drip irrigation and plastic mulch on growth and seed yield of Semialata. Two types of plastic mulch (green and silver/black) were tested at three levels of irrigation (120%, 100% and 80%) by drip irrigation and one level (100%) by furrow irrigation. The daily water requirement of Semialata was estimated by the equation ETcrop= ETox crop factor. ETcrop is crop water requirement mm/day. ETo (reference evapotranspiration, mm/day) was calculated by FAO calculator which uses temperature and humidity data. In this experiments there were twelve treatments were considered. The treatments were replicated thrice. The experiment was laid in randomized block design. It was observed that drip irrigation with or without plastic mulch is yielding better results in terms of growth parameters and seed yield as compared to furrow irrigation without plastic mulch. It was also observed that maximum suppression (67.58%) of weeds resulted with drip irrigation and silver/black plastic mulch at 80% level of irrigation.

The response of active ingredient, chlorophyll a and b contents, and chlorophyll index of henna to different rates of N fertilization and drought stress was explored in a split-split-plot experiment based on a randomized complete block design with four replications in the research farm of Jiroft Branch, Islamic Azad University, Jiroft, Iran in the 2016-2017 growing season. In the current study, the main plot was assigned to drought stress at three levels (including irrigation to supply 100%, 75% or 50% of plant water requirement), the sub-plot was assigned to N fertilization at three rates (50, 100 or 150 kg ha-1 pure N), and the sub-sub-plot was assigned to ecotype at three levels (Bami, Bushehri, and Rudbari). The results showed that the effect of drought level was significant on active ingredient and chlorophyll index at the p < 0.01 level and on chlorophyll a, total chlorophyll, and chlorophyll a/b ratio at the p < 0.05 level.  But, it could not influence chlorophyll b significantly. The effect of N fertilization was significant on most studied traits at the p< 0.01 level, but its effect was significant on the chlorophyll index at the p < 0.05 level and insignificant on dye and chlorophyll b. According to the results, it seems that the application of 100 kg ha-1 N and the irrigation to supply 75% of plant water requirement can contribute to having more fresh plants with the higher active ingredient and dye contents.

Water is essential for metabolism, substrate transport across membranes, cellular homeostasis, temperature regulation, and circulatory function. Although nutritional and physiological research teams and professional organizations have described the daily total water intakes (TWI, L/24h) and Adequate Intakes (AI) of children, women, and men, there is no widespread consensus regarding the human water requirements of different demographic groups. These requirements remain undefined because of the dynamic complexity inherent in the human water regulatory network, which involves the central nervous system and several organ systems, as well as large inter-individual differences. The present review analyzes published evidence that is relevant to these issues and presents a novel approach to assessing the daily water requirements of individuals in all sex and life-stage groups, as an alternative to AI values based on survey data. This empirical method focuses on the intensity of a specific neuroendocrine response (e.g., plasma arginine vasopressin (AVP) concentration) employed by the brain to regulate total body water volume and concentration. We consider this autonomically-controlled neuroendocrine response to be an inherent hydration biomarker and one means by which the brain maintains good health and optimal function. We also propose that this individualized method defines the elusive state of euhydration (i.e., water balance) and distinguishes it from hypohydration. Using plasma AVP concentration to analyze multiple published data sets that included both men and women, we determined that a mild neuroendocrine defense of body water commences when TWI is ˂1.8 L/24h, that 19–71% of adults in various countries consume less than this TWI each day, and consuming less than the 24-h water AI may influence the risk of dysfunctional metabolism and chronic diseases.

Enormous Variation

1. Attention is drawn to the enormous variations in yield experienced in commercial cotton growing under rain-fed conditions. Yields at Namulonge have ranged from 161 to 1163 lb./acre.2. In seeking an explanation of this enormous variation past and present fertilizer trials in Uganda have failed to show that much of this variation is due to nutrient status.3. From Manning's previous analysis of yields in relation to seasonal rainfall, over many district trials, it is evident that 20–25 in. of rainfall per season is optimum.4. The purpose of more recent studies has been to examine the effect of distribution of rainfall within the season. Clearly the pattern of crop water requirement, also within the season, must supersede a simple seasonal concept of crop water use.5. Experimental evidence, based on several seasons' data, led to the conclusion that evapotranspiration rates exceeding the commonly accepted figure of 0·8E must in fact occur in order to provide a satisfactory explanation of results recorded.6. The within-season pattern of water requirement of an annual arable crop is shown to be more dependent on its state of development than on the pattern of a physical model based on calculations of energy availability.

Irrigating plants based on their water requirements enhances water use efficiency and conservation; however, current irrigation practices for container-grown greenhouse plants largely relies on growers’ experiences, resulting in leaching and/or runoff of a large amount of water. To address water requirements of greenhouse-grown plants, this study adapted a canopy closure model and investigated actual evapotranspiration (ETA) of Calathea G. Mey. ‘Silhouette’ and Stromanthe sanguinea Sond. from transplanting to marketable sizes in a shaded greenhouse. The daily ETA per Calathea plant ranged from 3.55 mL to 59.39 mL with a mean cumulative ETA of 4.84 L during a 224 day growth period. The daily ETA of S. sanguinea varied from 7.87 mL to 97.27 mL per plant with a mean cumulative ETA of 6.81 L over a 231 day production period. The best fit models for predicting daily ETA of Calathea and Stromanthe were developed, which had correlation coefficients (r2) of 0.82 and 0.73, respectively. The success in modelling ETA of the two species suggested that the canopy closure model was suitable for quantifying water use of container-grown greenhouse plants. Applying the research-based ETA information in production could reduce water use and improve irrigation efficiency during Calathea and Stromanthe production.

AbstractPerformance of 80 (tests 1 and 2) or 60 (tests 3 and 4) weaned pigs were compared when using ‘Tubetype’ feeder (T), allowing the animals to mix meal and drinking water, or another type (V) where drinking and eating places are separated. The difference in growth rate was not significant but the mean daily water consumption (1 per pig per day) was higher with T than with V in each test but significantly only in tests 1 and 3 (1·84 v. 1·40, and 2·11 v. 1·26, P < 0·01).Feeding behaviour was assessed during tests 2 and 4. Multifactor analysis of variance revealed effects (P < 0·01) of feeder, group size and period of the day on the occupation time and the average number of animals using the feeders simultaneously. These two variables were higher for V than for T (test 2: 23·4 per 24 h v. 21·5 per 24 h and 4·5 v. 3·7, P < 0·05; test 4: 20·0 per 24 h v. 18·2 per 24 h, P< 0·01). In each test, both feeders were used for a longer time and by more piglets during the ‘day’ than during the ‘night’ (P < 0·01). When grouping 40 pigs, animals used both feeders during almost all the day period (V: 15·9 per 16 h and T: 15·8 per 16 h). During the night period, this was only true with V (V: 7·4 per 8 h; T: 5·8 per 8 h). The use of feeder V in crowded conditions thus prevented preferential diurnal feeding activity, commonly described in pigs. In conclusion, even if productivity is not affected, feeding behaviour and thus eventually welfare are influenced by the type of feeder, especially with high numbers of animals.

Drought Tolerance Indices

Drought is the main limiting factor of crops production in major regions of the world. Forage plants such as pearl millet and sorghum are drought tolerant and suitable for arid regions to grow. In this study, for selecting and introducing the best drought tolerant genotypes, seven pearl millet and five sorghum genotypes in three locations (Kerman, Jiroft, and Bardsir in Kerman Province) were studied with different climatic conditions. The experiments were conducted for three consecutive years of cultivation (2016, 2017, and 2018) under regularly irrigated conditions and the 100% (I100, full irrigation) plant water requirement and under water deficiency, (50%) plant water requirement (I50) in two randomized complete block designs in triplicate separately at each location. Eight drought tolerance/susceptibility indices were used. Multivariate factor analysis (FA) and stress tolerance score (STS) methods were employed to compare the most drought tolerant genotypes in each region. The STS method was more efficient and effective than the FA method for detecting the most drought tolerant genotype with any number of used genotypes. Based on the results of drought tolerance indices and STS, the IP13150 and IP13151 genotypes of pearl millet and speed feed genotype of sorghum in Kerman, Jiroft, and Bardsir respectively, were introduced as the most drought tolerant genotypes for three consecutive years of cultivation.
