In the Bazhenovskoye chrysotile–asbestos deposit (Middle Urals), nephrite bodies of the serpentinite type were found on the contact of after gabbro rodingites and serpentinites. The color is uniform to non-uniform, green to light green, bluish green, greyish green, and whitish. Spots, streaks, lenticules of bright bluish-green or, on the contrary, light green color are sometimes noted. The nephrite is mostly comprised of tremolite. Chromite decreases the quality of the ornamental stone, but it is replaced by chrome grossular, which gives the nephrite a brighter bluish-green color locally. Crushed grains of chromite contain increased concentrations of Zn and Mn. The quality of the nephrite is decreased by serpentine and talc, as well as by fractures due to drilling and blasting works. The specific feature of the nephrite in the Bazhenovskoye deposit is the formation of nickeline, maucherite, and uvarovite. The green color is associated with Fe2+ ions. The nephrite of the Bazhenovskoye deposit meets the requirements for an ornamental stone. The origin of this nephrite includes a combination of metasomatic and metamorphic processes.

Miller, J. J., Beasley, B. W., Drury, C. F., Larney, F. and Hao, X. 2015. Influence of long-term manure application on mineral composition of irrigated barley silage. Can. J. Plant Sci. 95: 759–770. The long-term effect of land application of manure type (composted vs. stockpiled manure), bedding type (wood-chips vs. straw), and application rate on feed quality of barley silage as feed for beef cattle is unknown. We measured selected minerals [P, Ca, Ca:P ratio, Mg, K, K:(Ca+Mg) ratio, Na, Fe, Mn, Zn, Cu] of irrigated barley silage (Hordeum vulgare L.) on a clay loam soil after 4 (2002), 7 (2005) and 11 (2009) years of annual applications of composted (CM) or stockpiled (SM) feedlot manure with wood-chips (WD) or straw (ST) bedding at three application rates (13, 39, 77Mg ha−1 dry wt.). The treatments also included an unamended control and inorganic fertilizer treatment. Manure type generally had inconsistent or no significant (P≤0.05) effect on the concentrations of these minerals in barley silage. Most crop minerals were generally greater under ST than WD. The findings for P, K, Na, and K:(Ca+Mg) ratio generally supported our hypothesis of greater crop concentrations with greater application rate, but Ca and Mg decreased at higher rates. Overall, our findings suggest that bedding and application rate have more potential than manure type for managing the feed quality of barley silage.

Anogeissus Leiocarpus

This study investigated the compost quality of sericulture waste on the growth of Anogeissus leiocarpus using two composting methods. The two-method adopted were M1 (pile method) and M2 (bin method). Sericulture waste which includes mulberry leaves and silkworm excreta were air dried for 24hours, measured (1 kg) and set in layers for both methods adopted. Samples of compost from each method were taken before planting to the laboratory for proximate analysis. Descriptive statistics and analysis of variance (ANOVA) were used to analyze the data obtained. Anogeissus leiocarpus seeds were soaked for 10 minutes at 35oC and at 9.5oC for 24 hours to enhance the breaking of its dormancy. Anogeissus leiocarpus seeds was planted using sericulture compost from both adopted methods. Result shows that M1 had the highest mineral composition. M1 recorded the highest (N %) with the value of 0.93%; (P %) with 0.089%; (K %) with 0.58%; (Ca %) with the value of 1.78% and (Mg %) with the value of 0.72% while M2 had a lower mineral composition. The result obtained for the early growth parameters shows that M1 had a higher plant height and stem girth which was significantly different from M2, the mixture of the two compost had the highest leaf count which was also significant while the control recorded the lowest value for all the parameters assessed. This result suggests that pile composting method is the best method for composting sericulture waste and can be used as a good and preferable alternative for inorganic manure in raising seedlings and trees species.  Adopting the use of sericulture waste as compost will help in reducing the waste management problem, enhance economic use of farm waste and also help to ease the low germination rate and germination percentage of Anogeissus leiocarpus.

Abstract Eastern goat’s rue (Galega orientales Lam.) possesses high fodder productivity and accumulates a large amount of vegetative mass with high humidity for harvesting for seeds. This greatly complicates the harvesting of grass stand for seeds. One of the ways to solve this problem is to carry out desiccation of the grass stand. A complicating factor in choosing the optimal harvesting period is the extended flowering and ripening period of goat’s rue beans, the duration of which reaches 25-35 days. The use of the drug Reglon Super based on diquat is a highly effective agrotechnical method that allows increasing the collection of seeds by 24%. The desiccation of the herbage contributes to the production of seeds with high sowing qualities. The seeds with the best sowing qualities are found in beans with yellow, brown, brown or dark brown color of the beans. In light green beans, the seeds are fully formed, but have a high moisture content. Goat’s rue beans do not crack or crumble at the onset of the full ripeness phase. This allows the seed to be harvested when most of the beans are ripe. A comparative assessment of the timing and method of harvesting the seed herbage of the goat’s rue showed that with a ripening of 39% and the presence of 47% of light green and yellow beans, the yield losses ranged from 26 to 56%. The highest seed yield in one confidence interval of 422-453 kg / ha and 444 kg / ha was obtained, respectively, by direct threshing with preliminary desiccation of the grass stand in the ripening phase of 74-97% of beans or by separate harvesting when mowing into swaths during ripening 74 % beans.

The effects of N and K fertilizer applications on yield, leaf mineral composition and fruit quality were studied at four locations in commercial cranberry plantings in experiments of 3 yr duration. Nitrogen applications at all locations increased leaf K content in the 1st and 3rd yr and decreased leaf Zn content at one location in the 2nd yr. Potassium applications increased leaf K content in all 3 yr of the experiment and decreased leaf Mg in the 2nd and 3rd yr. A significant location × N × K interaction influenced leaf K composition in the 3rd yr. Yield and fruit quality variables depended upon location but did not respond significantly to fertilizer application.

Madidi was produced from different formulations of pearl millet ogi and bambara nut flours. Five madidi products were produced at the laboratory scale using 100:0 (control), 95:5, 90:10, 85:15 and 80:20 millet to bambara groundnut flours, respectively. Bambara ground nut were cleaned, sorted (to remove foreign materials), soaked in cold water for 2 hours, dried and toasted for 30 minutes by using oven. The five formulated products were subjected to proximate, minerals and sensory analysis. The results showed that the protein contents increased with increased addition of bambara groundnut flour. The protein contents ranged from 1.79 to 3.51% on dry weight basis. The fat contents ranged from 0.26 to 1.22%. Carbohydrate content decreased from 22.00 to 13.21% as the proportion of bambara flour increased. Magnesium and phosphorous increased significantly (p=0.05), however potassium and iron were not significant affected (p=0.05). The 100% millet (0.17 mg/100 g) was significantly high in magnesium (p=0.05) followed by 95% millet and 5% bambara nut (0.09 mg/100 g). The phosphorous composition increased with increase in bambara nut (0.17– 0.22 mg/100 g). The average scores of parameters for all the products are relatively high. Product 85:15 millet to bambara flour was most acceptable. It is concluded that an acceptable madidi can be produced from millet and bambara nut at 15% substitution level.

Vegetable products are foods that are popular with many people. One vegetable product such as green chili is a vegetable commodity that cannot be abandoned by society in daily life. This was followed by demands for quality of green chili products. so that an analytical tool is needed that can analyze the freshness of green chili easily and practically. This study aims to develop an edible freshness sensor based on anthocyanin indicators from purple sweet potato extract (Ipomoea batatas L.) with a membrane mixture of cassava starch and chitosan. The edible freshness sensor can be applied as a freshness sensor and know the freshness level of green chili with various parameters. Tests for green chili freshness test included pH test, weight loss, texture value, and sensory evaluation test. The color change of the edible freshness sensor was observed visually and tested using the ImageJ program to determine the mean green value. The results show the color change of the freshness sensor is dark purple when the green chili is fresh, the light purple is still fresh and the light green is no longer fresh or rotten. The mean value of the green sensor for edible freshness increased along with the decline in the quality of green chili in the packaging. Keywords: Anthocyanin, tapioca starch, chitosan, green chilli
