Vermikompost Uygulamalarının San Andreas (Fragaria x ananassa Duch.) Çilek Çeşidinin Bazı Verim ve Kalite Değerlerine Etkisi

In this study, in which the effects of different applications of vermicompost on the yield and quality of San Andreas strawberry variety were investigated 15, 30, 45, 60 g vermicompost was applied per plant. First flowering, first and last harvest dates, number of fruits per plant, yield per plant (g/plant), fruit weight (g), fruit flavor, macro and micro nutrient content, organic acid amounts were examined. The results showed that the differences between treatments in yield per plant were statistically significant. The highest total yield per plant was obtained from V45 and V30 applications with 972.8 g and 878.9 g respectively and the lowest yield was obtained from the control application with 384.2 g per plant. The largest fruits were obtained from the V60 (19.5 g) application. It was determined that nitrogen, phosphorus, potassium, magnesium, sulfur, manganese, iron, zinc and boron concentrations in the leaves of strawberry plants fertilized with vermicompost were higher than the control. The highest values in organic acid values were determined in oxalic, propionic, malonic, lactic, fumaric and succinic acids in V60 application (5.62, 11.16, 49.00, 104.98 µg/100 g respectively). It seems that the application of vermicompost fertilizer in strawberry cultivation has a positive effect on yield and quality characteristics.

Path-coefficient and correlation analysis in Bambara groundnut (Vigna subterranea [L.] Verdc.) accessions over environments

In a breeding program, studies of genotypic and phenotypic relationships among agricultural crop traits are useful to design, evaluate, and develop selection criteria for desirable traits. Using path coefficient analysis, the present study was executed to estimate the phenotypic, genotypic, and environmental correlation coefficients between yield and yield-related traits and to determine the direct and indirect effects of yield-related traits on yield per plant. A total of 30 genotypes of Vigna subterranea were studied under tropical conditions at two sites over two planting seasons (considered as four environments). The experiment at each site used a randomized complete block design with three replicates. Data were collected on vegetative and yield component attributes. Based on analysis of variance, pooled results showed that there were positive and highly significant differences (p ≤ 0.01) among the 30 genotypes for all attributes studied. Highly significant and positive strong correlation at phenotypic level was observed for dry seed weight (0.856), hundred seed weight (0.754), fresh pod weight (0.789), and total pod weight (0.626) with yield in kg per hectare, while moderate positive correlations were observed for harvest cut (0.360) and days to maturity (0.356). However, a perfect positive correlation was observed for the dry weight of pods with seed yield. In contrast, days to 50% flowering (− 0.350) showed a negative significant relationship with yield per hectare. The dried pod weight attribute (1.00) had a high positive direct effect on yield. Fresh pod weight had the greatest indirect effect on yield per hectare, followed by the number of total pods by dry pod weight. As a result, dry pod weight, hundred seed weight, number of total pods, and fresh pod weight could be used as selection criteria to improve the seed yield of Bambara groundnut (Vigna subterranea).

DETERMINATION OF HERBAGE YIELD AND QUALITY OF DIFFERENT SOYBEAN VARIETIES

Objectives of the present study are to determine the variations in forage yield and quality of soybean cultivars. Experiments were conducted in randomized complete blocks design with 3 replications during the growing season of 2016. A total of 10 cultivars were used as the plant material of the experiments (Bravo, A3127, Traksoy, İlksoy, Mersoy, Nova, SA-88, Arısoy, Safir, Atakişi). Cultivars had a significant effect on yield and chemical composition. Results revealed that green herbage yields varied between 826.39 - 1199.17 kg/da, dry hay yields between 247.71 - 357.90 kg/da, crude protein yields between 16.91 - 39.86 kg/da, acid detergent fiber (ADF) ratios between 26.56 - 34.61%, neutral detergent fiber (NDF) ratios between 38.43 - 44.85%, crude ash contents between 7.20 - 11.22%, crude protein contents between 6.66 - 13.53%, dry matter digestibility (DDM) values between 61.94 - 68.21%, dry matter intake (DMI) values between 2.68 - 3.12% and relative feed values (RFV) between 2.68 - 3.12. The results of the study showed that A3127 cultivar was found to be prominent with green herbage yield (1199.17 kg/da) and dry hay yield (357.90 kg/da) and Safir cultivar was found to be prominent with crude protein yield (39.86 kg/da). It was concluded that the soybean cultivars A3127 and Safir could be recommended for hay production.

Influence of Planting Systems and Feeding Regimes on Dry Mass Accumulation of Cotton

Annotation: In order to increase the organic biomass in a bush, at least 15 t / ha of semi-rotted cattle manure before plowing, if possible plowed to 30 t / ha in autumn and then sowing in spring, retains the ability to absorb root activity longer, which has a positive effect on yield. reaches

Climate Change and Sustainability in Czech Wheat Production

The paper deals with the analysis of Czech wheat production and its determinants. We use the Just and Pope (1979) stochastic production function to estimate the effects of economic and weather variables, together with technological progress and climate change, on wheat yield in the Czech regions in the period 1961–2018. The results suggest that both economic and environmental factors play important roles in the wheat yield function. The output/input price ratio has a positive effect on the wheat yield. The effects of temperature and precipitation are month-specific and highly non-linear. Technological change also has a positive effect on yield, whereas climate change has a rather negative effect on wheat yield.

Effect of foliar spray of micronutrients and hormones on cauliflower (Brassica oleracea var. botrytis L.)

In order to achieve optimal plant growth and production, essential nutrients must be readily available in adequate quantities and in a balanced proportion to give a good yield, especially cauliflower which has health benefits that may not be found in many other plants. For this purpose, this experiment was carried out during the seasons 2020-2021 in the on station of Bangladesh Agricultural Research Institute, Khulna under Smallholder Agricultural competitiveness project. Although the treatments showed a positive effect on yield, quality and economics but, T1 revealed most significant influence on all parameters under study as compared to T0 (control). For micronutrients and hormone, T1 treatment produced the highest curd yield (29.99 t ha-1) and the lowest (17.04 t ha-1) was control from the varietal effect the highest curd yield was (35.14 t ha-1) from V4 (It Amazuku 33) and the lowest was (16.21 t ha-1) from V5 (BARI Fulcopi-1). In case of combined effect, the highest curd yield (45.16 t ha-1) was obtained from T1V4 and the lowest curd yield (10.27 t ha-1) from T0V1. Therefore, it can be suggested that the highest curd yield and good shape cauliflower curd can be obtained application of Zn 8.83 kg/ha, B 3.5 kg/ha, Ma 8.43 kg/ha and Flora (Hormone) 2 ml/1 L of water. Therefore, foliar application of micronutrients and hormone is suitable way to feed the cauliflower crop to enhance the marketable yield and quality.

Effect of hydrogen peroxide treatment on the concentration of volatile compound in coriander seeds oil

Coriander seeds essential oil have shown some remarkable biological properties and health benefits. The coriander seeds used in Indonesia are imported and also treated with hydrogen peroxide before reaching consumers. Hydrogen peroxide is known to be a strong oxidizer, but so far, there has been no information that explains its effects on the essential oil composition and concentration in coriander seed. This study aims to determine the effect of using hydrogen peroxide and the drying method on the composition of essential oils in coriander seeds. Yield and volatile oil compounds were measured, and the results were compared between the hydrogen peroxide concentration (0,35 and 50% ) and drying method (mechanical drying (50 ℃) and room temperature drying). GC-MS analysis detected linalool as the most common volatile constituent in all treatments. The highest concentration of linalool compounds (70.16%) was found in seeds without hydrogen peroxide (0%) treatment combined with mechanical drying, followed by without hydrogen peroxide (0% H2O2) combined with room drying (23.74%), then by 35% hydrogen peroxide combined with room drying (18.71%), 35% hydrogen peroxidecombined with mechanical drying (18.84%), 50% hydrogen peroxide combined with room drying (22.18%) and by 50% hydrogen peroxide combined with mechanical drying (15.45%). Therefore, the yield was clearly affected only by hydrogen peroxide treatment where no hydrogen peroxide treatment gave the highest yield. The drying method did not have any significant effect on yield.
