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.

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.

An experiment was designed with Randomized Complete Block Designed to investigate the effects of organic and inorganic nitrogen fertilizer at 90 kg N/ha on growth and leaf gas exchange in two varieties of Labisia pumila at 15 weeks after transplanting (WAT). In this study total biomass and photosynthesis (A) were significantly (P≤0.05) different among all factor. The results indicated that chicken manure enhanced the net photosynthetic rate (11.10 µmol/m²/s), stomatal conductance (0.40 mmol/m/s) and transpiration rate (5.30 mmol/m²/s) of L.pumila significantly after 31 weeks of planting. Chicken manure and Gobi indicated higher accumulation on total phenolic and total flavonoid compared to NPK green and control. Organic fertilizers (chicken manure and Gobi) were positively influenced the leaf gas exchange and growth of L.pumila as compared to the NPK green and control. This study proved that organic fertilizer can produce a quality of L. pumila compared to NPK green. Based on the principle of organic fertilizer which is slowly release from organic fertilizer will limit the nutrient availability for plant growth and allocate more carbon to produce secondary metabolites.

The reuse of drainages for cultivating more salt tolerant crops can be a useful tool especially in arid regions, where there are severe problems for crops water management. Dracaena deremensis L. plants were cultured in pots with sphagnum peat-moss and were subjected to three fertigation treatments for 8 weeks: control treatment or standard nutrient solution (D0), raw leachates from Chrysalidocarpus lutescens H. Wendl plants (DL) and the same leachate blending with H2O2 (1.2 M) at 1% (v/v) (DL + H2O2). After harvesting, ornamental and biomass parameters, leaf and root proline and total soluble sugar concentration and nutrient balance were assessed in each fertigation treatment. Plant height, leaf and total dry weight had the highest values in plants fertigated with leachates with H2O2, whereas root length, leaf number, RGB values and pigment concentration declined significantly in plants fertigated with leachates from C. lutescens with or without H2O2. The fertigation with leachates, regardless of the presence or absence of H2O2 increased root and leaf proline concentration. Nevertheless, root and leaf total soluble sugar concentration did not show a clear trend under the treatments assessed. Regarding nutrient balance, the addition of H2O2 in the leachate resulted in an increase in plant nutrient uptake and efficiency compared to the control treatment. The fertigation with leachates with or without H2O2 increased nitrogen and potassium leached per plant compared to plants fertigated with the standard nutrient solution. The reuse of drainages is a viable option to produce ornamental plants reducing the problematic associated with the water consumption and the release of nutrients into the environment.

In the years 2011–2014, winter wheat grain yield, qualitative and economic parameters were evaluated according to different fertiliser treatments: (1) control: unfertilised treatment; (2) farmyard manure (FYM) and (3) FYM + NPK (farmyard manure applied together with mineral NPK). The highest yields (8.10 t/ha) were recorded in the FYM + NPK treatment, while significantly lower yields (6.20 t/ha and 5.73 t/ha) were recorded in FYM and control treatments, respectively. Similarly, statistically significantly higher values of the quality parameters were found in the FYM + NPK treatment (13.55% of crude protein content and 43.56 mL of Zeleny’s sedimentation test), compared to control (10% and 22.44 mL, respectively). The modelling expert system (AGROTEKIS-Crop Technology and Economy) was used for the evaluation of economy. This software is based on technological methods of cultivation and norms of material input costs and costs of individual mechanised works. The economic benefits and profitability were evaluated for three different levels of grain market price. The highest gross profit per ha was recorded in the FYM + NPK treatment. According to the gross profit, the control treatment provided better results than the FYM treatment.

The present research was conducted on two factor Completely Randomized Design (CRD) with eight treatments and three replications. A set of experiments were carried out to evaluate the effect of postharvest ethephon treatment and packaging on ripening of mango cv. Maldah. The treatments consisted of ripening agent i.e., ethephon and control treatment under different packaging condition i.e., fiber with hole, fiber without hole, plastic with hole and plastic without hole. The result revealed that different packaging condition and ripening agents influenced the ripening behavior of mango. The highest TSS (15.26), sugar-acid ratio (23.66) and juice content (126.05) were recorded with fiber (without hole) and the lowest TSS (12.60), sugar-acid ratio (9.01) and juice content (116.05) with plastic (without hole). The highest TA (1.44) was recorded with plastic (without hole) and the lowest (0.66) with fiber (without hole). Similarly, the highest BT (2.83) was recorded with fiber (with hole) and the lowest (1.66) with plastic (without hole). Firmness, sweetness, TSS and juice content were the highest with the interaction effect of fiber bag (without hole) and ethephon treatment. In conclusion, mango fruits with ethephon treatment packed in fiber bag (without hole) enhances quality and ripening of mango whereas under controlled condition and without hole plastic packaging mangoes had low quality performance in terms of physio-chemical properties.
