TL;DR: In this paper, the effect of BioField Energy applied to two separate crops under typical growing conditions, namely ginseng and organic blueberry in commercial plantings in Wisconsin and California, was tested.
Abstract: This study tested the Null Hypothesis for the effect of BioField Energy applied to two separate crops under typical growing conditions, namely ginseng and organic blueberry in commercial plantings in Wisconsin and California, respectively. Following treatment to replicated plots in standard experimental design, data were collected at harvest for yield quantity and quality. Ginseng plants treated both pre-harvest and a combination of pre- and post-harvest showed market grade increases of 33.3% and 40.0%, respectively. Point of sale gross return for this crop is dependent upon tuber quality, and from these data the economics of these treatments were calculated. Based on stand adjusted yields and quality values, a combination of pre- and postharvest treatment increased gross income by 57.4%. The second crop showed similar trends in positive responses. In the two blueberry varieties studied, Emerald treated plants showed 96% statistical increase in yield, while Jewel showed 31% increase. At the time of treatment, each variety was in a different stage of flowering. The Emerald variety was in the flowering stage, and Jewel was predominately in the fruiting stage. Both treated cultivars however demonstrated increased yield quantity and quality. The specific mechanisms that lead to these preliminary results need further investigation.

TL;DR: It is better to use osmo-priming (PEG 200 g L -1 ) for teaching aerobic rice seed against drought stress and more research is needed to confirm benefits of seed treatment with PEG to cultivated crops under water stress, drought and salinity conditions.
Abstract: This study compared hydro- and osmo-priming to determine period needed for seed priming indicator to emerge and its effect against water stress on germination percentage of some aerobic rice cultivars ( Oryza sativa L.). Experiments were arranged in completely randomized design using three aerobic rice cultivars and PEG with four replications. Rice varieties (Inpago-8, IR64 and Situ Bagendit) were combined with four different PEG concentrations. Drought stress was simulated by different PEG solutions and with distilled water as control. Results indicated differentiations between hydro and on priming indicator time, while varietal difference was not significant. Fastest recorded time was obtained between 30-36 hours under hydro priming, PEG 100 g L -1 (63-69 hours) and 83-93 hours in PEG 200 g L -1 solution. Thus showing increased solution concentration led to prolonged priming indicator time. The highest germination percentage was obtained in Situ Bagendit treated with PEG 200 mg L -1 (90.25%) and the lowest obtained in Inpago-8 (75.75%) under control. It is better to use osmo-priming (PEG 200 g L -1 ) for teaching aerobic rice seed against drought stress. More research is needed to confirm benefits of seed treatment with PEG to cultivated crops under water stress, drought and salinity conditions.

TL;DR: Fruit characters of Pisang Berlin and Ambon Hijau are close related to their ancestral parents’ Musa acuminata wild species, whereas Pisang Kepok and Pisang Raja Bandung as hybrid cultivars have intermediate characters between Musa Acuminata and Musa balbisiana wild species.
Abstract: Aims of this research were to describe the morphology and analyze nutrient values of mature fruits at three different genomic groups of Indonesian banana cultivars including Pisang Berlin (AA), Ambon Hijau (AAA), Raja Bandung (ABB) and Kepok (ABB). Fruit characterization results show that each banana cultivar had specific characteristics related to their genomic group. Pisang Berlin has bright yellow peel and pulp, sugary taste. Pisang Ambon Hijau has fine curved fruit shape, sweet taste and aromatic. Pisang Raja Bandung has medium thickness and yellow peel, firm flesh, sweet and slightly acidic taste. Pisang Kepok has thick coarse and yellow peel with dark brown blotches, mild sweet taste. Fruit characters of Pisang Berlin and Ambon Hijau are close related to their ancestral parents’ Musa acuminata wild species, whereas Pisang Kepok and Pisang Raja Bandung as hybrid cultivars have intermediate characters between Musa acuminata and Musa balbisiana wild species. Nutrient analysis revealed that mature banana pulp contain of high carbo-hydrates (16.72-35.24 g 100g -1 ), total sugar (12.12-20.82 g 100g -1 ), vitamin C (16.45-30.27 g 100g -1 ) and potassium (275-375 g 100g -1 ); moderate protein (1.48-1.78 g 100g -1 ) and low fat (0.03-0.08 g 100g -1 ). About 100 g edible portion of banana fruit produce 73.43 to 148.80 calories.

TL;DR: Results showed no differences among cultivars tested but interaction of factors studied were found in all parameters observed, and LEDs spectral gave significant influence on the morphogenetic processes from callus induction to complete plantlet formation.
Abstract: This paper elucidates the effects of LEDs spectral on callus induction, proliferation and shoot development of anthurium plantlet derived from leaf explants. The research was conducted at the Ornamental Research Station, Fukuyama, Japan from January to August 2008. Three experimental series were designed to determine the effects of LED-based spectral compositions i.e. 100% red, 75% red + 25% blue, 50% red + 50% blue, 25% red + 75% blue and 100% blue LEDs on morphogenetic process of callus formation derived from leaf explants up to plantlet formation on two anthurium cultivars, Violeta and Pink Lady. The results showed no differences among cultivars tested but interaction of factors studied were found in all parameters observed. LEDs spectral gave significant influence on the morphogenetic processes from callus induction to complete plantlet formation. Progressive initial callus was promoted with the decrease of blue LEDs portion. Conversely, to proliferate globose to torpedo callus formation, more blue light was required than red LEDs. During shoot induction and formation, hastened shoot initiation and number of shoots were achieved in higher blue LEDs portions, but not in root formations.

TL;DR: For at least fifteen years, with ever increasing frequency and extent, weather modification and/or climate alteration investigations have been conducted without public disclosure to perfect a covert methodology for inhibiting rainfall to deliberately damage a sovereign nation's agri-cultural economy as discussed by the authors.
Abstract: For at least fifteen years, with ever increasing frequency and extent, weather modification and/or climate alteration investigations have been conducted without public disclosure to perfect a covert methodology for inhibiting rainfall to deliberately damage a sovereign nation’s agri-cultural economy. This research discloses methodology for inhibiting rainfall, the evidence of coal combustion fly ash utilization, the adverse consequences on agriculture, and the adverse health implications on biota, including humans. The harm to agriculture comes primarily from aluminum addition to soil, changing soil pH and changing historic weather patterns. Aluminum in a chemically mobile form, not only harms plants, but is toxic to most biota, including humans. The micron and submicron particulates are used for weather modification contain heavy metals and radioactive elements which pose potentially grave human health threats including, but not limited to, cardiovascular disease, diabetes, respiratory diseases and reduced male fertility. Understanding that methodology and its adverse consequences by the agricultural community is crucial to identify and stop covert operations aimed at damaging the agricultural economy of a sovereign nation.
