Organic Nutrients

Aims: Organic nutrients such as animal manures, plant-derive compost, biosolids and bioliquids contain varying amounts of plant nutrients and can improve the biological, chemical, and physical properties of soils. They are used primarily for promoting growth of a plant or improving the quality of a crop. Study was aimed to find out the effect of conventional and fifteen different organic nutrients (peat, compost, cattle manure, chicken manure, horse manure, sheep manure, pigeon manure, vermicompost, seaweed + cattle manure, compost + humic acid, cattle manure + humic acid, chicken manure + humic acid, horse manure + humic acid, sheep manure + humic acid and peat + humic acid) on some quality properties of popcorn. Study Design: Trial was designed in complete randomized block design with three replications. Ant-Cin-98 popcorn cultivar was used in the study. Each parcel comprised 4 lines. The planting was made into a depth of 5-6 cm along the lines 5 meters long with a row spacing of 70 cm and intra row of 20 cm. Place and Duration of Study: This study was conducted in Diyarbakır - Cermik conditions of Turkey between 2010 and 2011. Methodology: The effect of conventional and fifteen different organic materials to some quality parameters of popcorn such as cob ratio, 1000-kernel weights, test weight, popping volume and number of unpopped kernel were evaluated in the study. Physical and chemical properties of the trial area were determined by taking soil sample from a depth of 0-30 cm on the trial area before planting. Results: According to the investigated results, the highest and the lowest values were ranked between 19.98% (peat + humic acid) and 17.26% (vermicompost) for cob ratio, 138.65 g (seaweed + cattle manure) and 122.48 g (chicken manure) for 1000-kernel weight, 81.29 kg hl-1 (horse manure + humic acid) and 75.62 kg hl-1 (vermicompost) for test weight, 19.71 cm³ g-1 (peat) and 17.17 cm³ g-1 (sheep manure + humic acid), for popping volume 5.92% (peat) and 3.65% (horse manure + humic acid) for number of unpopped kernel. Conclusion: Higher values were obtained from organic nutrient sources than conversional application in all tested quality parameters. The implementation of organic fertilizers together with humic acid in popcorn produced better results in comparison to alone implementation of organic fertilizers. Also it was determined that use of natural enemies of Trichogramma spp against corn borer can be possible without any chemicals.

Laboratory experiment was conducted using silty clay loam soil collected from Agriculture fields in Abu Ghraib to study the release of phosphorus from rock phosphate (10.22 P%) on  a soil treated with three types of organic fertilizers namely; peat moss , sheep manure  , poultry manure and  control treatment (soil only). Ten grams of air dried soil  mixed with 100 mg of ground rock phosphate  and  organic fertilizers added at 2.5% level (w:w) were  incubated at a laboratory temperature (298 K ) after adding  water  up  to two-thirds of the field capacity for 40, 90, 120, 150 and 180 days. Citric  acide  soluble  available phosphorous  was estimated after each incubation periods and kinetic equations used to test its release from treated samples. The additions of chicken manure was the highest in the  amount  of  dissolved phosphorus values followed by sheep manure, peat moss, rock phosphate and control treatment, reaching levels of citric  acide  extractable  phosphorus to  4.2 , 3.8, 3.3, 3.1 and 2.5 mg P kg-1 soil, respectively. The results also showed superiority of first  order equation in the description of phosphorus release from rock phosphate with  release  rate   coefficient  of 3.801 , 3.865 , 4.328 and 4.366 mg P kg -1 soil h-1 for the treatments: soil and rock phosphate only , peat moss, sheep waste and chicken manure, respectively.

The objective of this research was to study the effect of bokashi livestock on the growth and yield of tomatoes. The experiment was conducted in Bandar Lampung from October 2009 until February 2010. The experimental design was randomized complete block design with 3 replications. The treatments were: control; inorganic fertilizers at a recommended rate of (kg ha-1) 135 N, 75 P2O5, and 110 K2O (RR); chicken manure bokashi + RR; chicken manure bokashi + 50% RR; cow manure bokashi + RR; cow manure bokashi + 50% RR; sheep manure bokashi + RR; sheep manure bokashi + 50% RR; horse manure bokashi + RR; horse manure bokashi + 50% RR. Each bokashi treatment was applied at the rate of 20 ton ha-1. The result of experiment showed that chicken manure bokashi was the best among bokashi livestock. The application of 50% RR combined with chicken, cow, sheep or horse manure bokashi gave a higher yield than treatment with inorganic fertilizer at recommended rates. These results demostrated that the application of bokashi livestock could potentially reduce the use of inorganic fertilizers while maintaining higher yield.

The study evaluated the agronomic performance of green maize grown on residual organomineral fertilization used in the industrial tomato crop. The randomized block design was used, with three replications and eight treatments as follows: control (without fertilizer application); mineral fertilizer; cattle manure; organomineral with cattle manure + MAP (monoammonium phosphate); chicken manure; organomineral with chicken manure + MAP; broiler litter; and organomineral with broiler litter + MAP. All of those treatments were applied to the tomato crop that preceded the green maize crop. After the tomato harvest, maize was sown in the same tomato growing row. Growth variables of green maize plants and ears were evaluated. The green maize grown in areas with residues of chicken and cattle manure, used as fertilizers in the tomato crop preceding the maize crop, resulted in a number of commercial ears similar to when mineral fertilizer was used. The same similar results were obtained for ear quality and yield. The use of organic fertilizers in the industrial tomato crop presented high viability, which made possible to replace the use of mineral fertilizers in the subsequent green maize crop.

Copper is a microelement involved in the metabolism of nitrogen compounds in plants. Good utilization of nitrogen from soil and fertilizers by plants requires an adequate supply of copper. The aim of the study was to determine the effect of increasing levels of copper (100, 200, and 300 mg Cu·kg−1 of soil) applied together with various organic fertilizers (cattle manure, chicken manure, and spent mushroom substrate) on nitrogen content and uptake by cocksfoot (Dactylis glomerata L.) and the coefficient of nitrogen utilization from organic fertilizers. The pot experiment was carried out in three growing seasons (May–September) in greenhouse, and in this cocksfoot was grown and harvested four cuts in each year. Copper and organic fertilizers were applied once in the first year before sowing cocksfoot, and the after-effect was investigated in the second and third years. Application of different amounts of copper did not influence the nitrogen content in the biomass of cocksfoot. At the same time, soil application of this micronutrient in the amount of 100 mg Cu∙kg−1 of soil caused an increase in nitrogen uptake in the biomass of cocksfoot. Application of 100 and 200 mg Cu·kg−1 of soil caused an increase in the coefficient of nitrogen utilization from the organic fertilizers, which was highest effect in the case of cattle manure. All of the organic materials used increased the content of nitrogen and its uptake by cocksfoot, but the greatest effect was noted following application of chicken manure. The study showed no synergistic or antagonistic relationships between copper and nitrogen.

Hylocereus Polyrhizus

O cultivo da pitaya (Hylocereus spp) foi introduzido, no Brasil, na década de 1990. No Estado de Mato Grosso do Sul, uma das espécies exploradas, dentro deste gênero, por produtores da agricultura familiar, é a Hylocereus polyrhizus (Weber) Britton & Rose. Apesar do crescimento da área cultivada existem poucas informações sobre as melhores condições para o cultivo das plantas, o que dificulta maiores ganhos em produtividade. Por este motivo, justifica-se investigar o uso de substratos para avaliar o crescimento inicial da pitaya, tais como: os orgânicos. Levando-se em consideração a importância da espécie para a agricultura familiar, objetivou-se avaliar o crescimento inicial de Hylocereus polyrhizus em diferentes substratos, enriquecidos com materiais de origem orgânica. O delineamento experimental foi o inteiramente casualizado em esquema fatorial 5 x 4 (5 tratamentos x 4 repetições), em que a espécie foi cultivada frente a três adubos orgânicos e duas testemunhas, durante 360 dias. Os tratamentos foram: T1 – testemunha (100% solo arenoso), T2 – testemunha (NPK), T3 – 90% solo arenoso + 10% de cama de frango, T4 – 80% solo arenoso + 20% esterco bovino e, T5 – 80% solo arenoso + 20% esterco ovino. Os resultados de crescimento inicial foram analisados aos 360 dias. A pitaya, quando em solos arenosos, cresce, floresce a frutifica mais rapidamente na condição do tratamento 4 (80% solo + 20% esterco bovino).   Palavras-chave: Desenvolvimento. Ambiente e Sustentabilidade. Hylocereus spp. Adubação Orgânica. Crescimento Inicial.   Abstract  The pitaya cultivation (Hylocereus spp) was introduced in Brazil in the 1990s. In the State of Mato Grosso do Sul, one of the species explored, within this genus, by family farmers, is Hylocereus polyrhizus (Weber) Britton & Rose. Despite the growth of the cultivated area, there is little information on the best conditions for the plants cultivation, which hinders greater gains in productivity. For this reason, it is justified to investigate the use of substrates to evaluate the pitaya initial growth, such as organic ones. Taking into account the importance of the species for family farming, the objective was to evaluate the initial growth of Hylocereus polyrhizus on different substrates, enriched with materials of organic origin. The experimental design was completely randomized in a 5 x 4 factorial scheme (5 treatments x 4 repetitions), where the species was grown before three organic fertilizers and two controls, for 360 days. The treatments were: T1 - control (100% sandy soil), T2 - control (NPK), T3 - 90% sandy soil + 10% chicken manure, T4 - 80% sandy soil + 20% bovine manure and, T5 - 80% sandy soil + 20% sheep manure. The results of initial growth were analyzed at 360 days. Pitaya, when in sandy soils, grows, blooms and bears fruit faster under treatment 4 (80% soil + 20% bovine manure).   Keywords: Development.

Physiological process of germination depends on several factors such as temperature, water potential, light and nutrients. A laboratory study was carried out to asses, the effect of different Vermiwash sources on germination and seedling growth of fenugreek. A factorial design was used with four replications. Treatments were factorial of different Vermiwash (water as a control=W0, Vermicompost extract of wheat straw=W1, horse manure=W2, sheep manure=W3, 25% straw + 75% horse manure =W4, 25% straw + 75% sheep manure =W5, 50% straw + 50% horse manure =W6, 50% straw + 50% sheep manure =W7, 25% alfalfa residue + 75% sheep manure =W8, 50% alfalfa residue + 50% sheep manure =W9, 25% chicken manure + 75% straw manure =W10) and two levels of Vermiwash concentration (20% and 40%). Results showed that germination rate was significantly affected by all treatments. The maximum germination rate was observed at concentration of 40 percent of vermiwash with 25% alfalfa residue + 75% sheep manure. The maximum percentage of germination was obtained in 20 percent of vermiwash with sheep manure treatment and concentration of 40% in wheat straw. A significant difference was observed through treatments at 1% level in root length. In addition, root dry weight differed significantly among treatments at the 5% level. Also, a significant increasing was considered in root length by increasing the concentration of vermiwash.

Composting is an environmentally friendly way to turn plant and animal wastes into organic fertilizers. However, it is unclear to what extent the source of animal waste products (such as manure) affects the physicochemical and microbiological properties of compost. Here, we experimentally tested how the type of livestock manure of herbivores (sheep and cattle) and omnivores (pig and chicken) influences the bacterial and fungal communities and physicochemical properties of compost. Higher pH, NO3-N, Total carbon (TC) content and C/N were found in sheep and cattle manure composts, while higher EC, NH4-N, Total nitrogen (TN) and total phosphorus (TP) content were measured in pig and chicken manure composts. Paired clustering between herbivore and omnivore manure compost metataxonomy composition was also observed at both initial and final phases of composting. Despite this clear clustering, all communities changed drastically during the composting leading to reduced bacterial and fungal diversity and large shifts in community composition and species dominance. While Proteobacteria and Chloroflexi were the major phyla in sheep and cattle manure composts, Firmicutes dominated in pig and chicken manure composts. Together, our results indicate that feeding habits of livestock can determine the biochemical and biological properties of manures, having predictable effects on microbial community composition and assembly during composting. Manure metataxonomy profiles could thus potentially be used to steer and manage composting processes.

Sugar apple (Annona squamosa L.) is one of the most widely grown member of the Annonaceae family in several regions, but there is still a lack of agronomic data regarding the management of its initial growth stages under Cerrado conditions. The aim of the present study was to evaluate the production of Annona squamosa L. seedlings under different environmental conditions achieved by using shade nets (E1: ChromatiNet® Silver 50%; E2: ChromatiNet® red 50%; E3: ChromatiNet® red 35%; E4: ChromatiNet® Silver 35%) in combination with four different substrates (S1: soil + sand + chicken manure; S2: soil + sand + cattle manure; S3: soil + sand + cattle manure + chicken manure; S4: soil + sand + sheep manure). An experiment was set up using a completely randomized design with treatments in a split-plot arrangement, with four replicates and ten plants per experimental unit. Seedling growth parameters and quality indices were evaluated. The tested environments had higher local temperatures relative to the external environment, which had a negative effect on plant growth. Environment E2 resulted in the highest plant height and dry weight, but led to uneven growth among the evaluated plant parts. The substrate with sheep manure (S4) did not benefit seedling production. The best results for seedling growth and quality were obtained with substrates S2 (soil + sand + cattle manure) and S3 (soil + sand + cattle manure + chicken manure), which are therefore promising for Annona squamosa L. seedling production in the Roraima Cerrado.

Copper is an element necessary for the proper growth and development of plants, but when taken in excess amounts, it can be toxic. Its availability for plant can be reduced by using organic fertilizers or soil liming. The aim of the study was to investigate the effect of increasing doses of copper (100, 200, and 300 mg Cu·kg−1 of soil) application in combination with various organic amendments (cattle manure, chicken manure, and spent mushroom substrate) on the yield of cocksfoot and its content and uptake of this metal, and to determine its coefficient of bioaccumulation and tolerance indices. The toxic effect of copper manifested by significant decrease in the yield of the test plant was after the application of 300 mg·kg−1 of soil. Increasing doses of copper application increased its content and uptake by the test plant, while observing the decreasing bioaccumulation factor. All the soil amendments reduced the toxic effect of copper on cocksfoot. The most effective organic amendment in terms of yield and protective effects against high levels of copper was cattle manure, in the case of which the Org/Cu and Cu/Org tolerance indices were highest.
