Positive Effect

SUMMARYIn a preliminary laboratory experiment in Iran, not reported here, 5 out of 30 plant materials incorporated into a highly calcareous soil had a positive effect on increasing the DTPA- (diethylenetriaminepentaacetic acid)-extractable Fe and all except one significantly increased the vegetative growth of sorghum. The plant materials included Lawsonia inermis L., Malva silvestris L., Zyzyphus nummularia Wak. and Lavandula carnopifolia L. A glasshouse study was repeated with two California soils pretreated with 0·5% Fe2O3 to determine if these organic materials have practical value in making Fe available to plants. A calcareous, Fe-deficient Hacienda (fine-loamy, mixed, thermic aquic natrargid) and a non-calcareous Yolo (fine-silty, mixed, non-acid, thermic typic xerothents). The previously mentioned organic materials and Laminaria saccharina L. (Lamour) were incorporated into the soils at two rates, 15000 and 20000μg/g, as air dry and in ash form. An adequate supply of major and micronutrients other than Fe was ensured. Other treatments included 5 μg Fe/g as FeSO4, Fe-138 chelate and control. All of the plant materials with the exception of L. carnopifolia significantly increased dry-matter yield and Fe, Zn, Cu and Mn uptake by sorghum in the Hacienda soil. In the Yolo soil the above were not significant. Thin-layer chromatography of the extracts of the plant materials revealed the presence of significant quantities of phenolic substances.

A study of the effectiveness of the use of feed additive Liatoxil in vivo in broiler chickens to study the ability of feed additives to improve digestion and affect the digestibility of nutrients. For research was formed on the principle of analogues -day age. Feeding of the control group was carried out with standard feed. Feeding of the experimental group was carried out with standard feed, in which the feed additive Liatoxil was added at the rate of 2 g / kg. The calculation of the digestibility of nutrients of the experimental and control feed was determined by their content in the feed and manure in terms of absolutely dry matter. It is established that the studied feed additive has a positive effect on the digestibility of feed nutrients. As a result of the use of feed additive Liatoxil, the digestibility of organic matter increased by 2.8 % compared to the control. The coefficient of protein digestibility in animals of the experimental group exceeded this indicator of the control group by 4.2 % and was 93.3 % against 89.1 % in the control. The digestibility of crude fat in poultry of the experimental group was 77.8 % and also exceeded by 2.0 % the value of the control group, which was 75.8 %. The studied feed additive did not significantly affect the digestibility of crude fiber, which was 23.3 % in the control and 23.5 % in the experiment. At the same time, the obtained data show that in the animals of the experimental group the digestibility of nitrogen-free extractives was 87.5 %, which is 2.8 % higher than this indicator of the control group.

In connection with a decrease in soil fertility, it is necessary to revise the doses of mineral fertilizers when growing watermelons of the Shirin variety in the Tashkent region of Uzbekistan. It is also necessary to establish the doses of fertilizers that have a positive effect on the yield and quality of the products obtained. The research was carried out at the experimental base of the Research Institute of Vegetables - Melons and Potatoes, located in the Tashkent region. The soils where the studies were carried out are typical gray soils of old irrigation with a humus content in the upper 0-25 cm horizon of about 1%, in the lower 25-40 cm horizon - about 0,7%. Calcareous soil, in texture referring stay to the dark loam average at density. During the research, the previously recommended doses of fertilizers were taken for control. During the experiments, the doses of mineral and organic fertilizers were increased accordingly. Studies have shown that the highest yield of good quality watermelons was obtained when applying 25,0 t/ha of manure in combination with N225 P225 K150  kg/ha and was equal to 21,2 t/ha, which is 37,7% higher than on the control variant (N150 P150 K100  kg/ha) and had good biochemical indicators of product quality: sugars 8,11%, dry matter 9,1%, ascorbic acid 21,6 mg%, nitrogen nitrates 20,6 mg/kg, on the control these indicators were equal to 6,65%, 8,6%, 17,9 mg%,13.2 mg/kg, respectively.

AbstractThe nutritional value of different categories of peas was measured in mash or pelleted diets using adult cockerels. Twenty-five round and white-flowered peas (feed peas), 12 round and coloured-flowered peas and five wrinkled and white-flowered peas were used in mash diets. From the same batches, 11 feed peas, five coloured peas and four wrinkled peas were tested in pelleted diets.Mean apparent metabolizable energy (AME) values were 12·02, 11·35 and 10·50 MJ/kg dry matter (DM) for feed peas, coloured peas and wrinkled peas respectively in mash diets and 13·18, 12·72 and 11·63 MJ/kg DM for the same categories in pelleted diets.Mean starch digestibility was 0·905, 0·887 and 0·802 for feed peas, coloured peas and wrinkled peas respectively in mash diets and 0·985, 0·984 and 0·840 for these categories in pelleted diets.Mean protein digestibility was 0·788, 0·643 and 0·798 for feed peas, coloured peas and wrinkled peas respectively in mash diets and corresponding values for peas in pelleted diets were 0·855, 0·743 and 0·853.Pelleting thus had a positive effect on the nutritional value of peas and this improvement was all the more important because the AME and protein digestibility of the pea in mash diets was low.The nutritional value of feed peas for cockerels was not strongly correlated with chemical composition or to digestibility data obtained in the pig.

ABSTRACT: An experiment was conducted during the years 2009 and 2010 to evaluate the effects of Urochloa forage straw and nitrogen fertilization on soil properties, nutritional foliar content, index of foliar chlorophyll (IFC) values, production components, and grains yields of winter bean (Phaseolus vulgaris 'Pérola') in the Cerrado lowlands region of Brazil. The treatments consisted of planting bean crops under straw of Urochloa brizantha 'Xaraés' and Urochloa ruziziensis, fertilized with urea-sourced N (0, 50, 100, 150, and 200 kg N ha-1). The experimental design was randomized blocks with four replications, and a factorial scheme of 2 × 5. The greater yield of U. brizantha dry matter in the two years of evaluation increased bean leaf nutrient levels. The nutritional increase with increasing N application rates showed that the straw produced by the forages had a positive effect on bean nutrition. The grain yield was satisfactory but was not affected by the forage species nor by changes in the N application rates. The Urochloa straw increased the soil organic matter (SOM), Ca, and Mg content in both evaluated years, affected the decomposition and mineralization of organic residues, and ensured the proper development of the bean plants.
