| Five wheat genotypes including two commercial cultivars (Mist1 and Misr2) and three Ug99-race specific genes (Sr24, Sr25, and Sr31) were screened for stem rust resistance based on phenotypic and genotypic reaction. Based on phenotypic reaction, Sr24 (LcSr24Ag) and Sr31 (Seri-82) exhibited seeding and adult plant resistance while the wheat cultivars, Misr1 and Misr2 were susceptible. Sr25 Agatha (CI 14048)/9*LMPG-6 DK16 exhibited seedling resistance while showed susceptibility at adult plant stage. Based on genotypic reaction, DNA markers showed that gene Sr25 was only found to be present in Misr1 and Misr2 while Sr24 and Sr31 were absent in both cultivars. Although, virulence to Sr25 was detected. However, avirulence to Sr24 remains this gene as a suitable... |

| Direct measurement of saturated hydraulic conductivity (Ks) and dry bulk density (rb) is often laborious, time consuming, and expensive. Predicted dry bulk density (rb-ADR) using Amplitude Domain Reflectometry (ADR) probe has been employed to predict saturated hydraulic conductivity (Ks_ADR) after a slight modification on the previously available Non-Similar Media Concept (NSMC) model. All the predicted values were validated using the corresponding measured data of 108 undisturbed samples for each of 0-15 and 15-30 cm soil depths observed. The proposed “Dielectric NSMC” model could describe rb_ADR dependencies of Ks_ADR better than the other proceeding models for the both ranges of soil depths observed. The proposed model tended to slightly underestimate... |

| This study evaluates the performance of a modified flour mixer for use as a wet bean de-hulling device. The effect of soaking time, running time and operating speed was investigated. The machine was driven at 150, 200, 250, 300 and 350 rpm, for operating times 1, 2, 3, 4 and 5mins in dehulling beans soaked in water at ambient temperature of 29 ± 2oC for 2, 4, 6, 8 and 10 minutes. The results showed that soaking time, operating speed and machine running time have significant effect (at 5% significance level) on all the performance indices of the machine. The highest de-hulling efficiency of 92.68% with percentage seed breakage of 31.35% was observed for black eye pea; corresponding values for brown beans were 91.65% and 25.20% respectively. These values... |

| Overall objective of this study was to evaluate the dispersion of aerosol plumes generated by a truck-mounted ultra low-volume (ULV) applicator and a hand-held thermal fogger under open field conditions. Experiments were also planned to determine the relative capture efficiencies of various sampling techniques in such applications. The ULV applicator was used at three travel speeds (8.5, 16.8, 24.8 km/h) and the thermal fogger at two release heights (0.6 and 1.1 m above ground) to investigate the effect of speed or release height on deposition at 6, 12, 24, and 48 m downwind. High volume air sampler (HVS), low volume air samplers (LVS), spinning cotton ribbon (CR) samplers, polypropylene green plastic cards (GC), acetate cards... |

| Engineering parameters of the bed planter and the inclined plate planter for bed planting, minimum tillage, strip tillage and conventional tillage cum hand planting methods were estimated at Gazipur. Field tests of the machines for different tillage practices were conducted at Gazipur, Pabna, and Barisal. Field tests were conducted with four treatments: Bed planting with inclined plate seed metering, minimum tillage with inclined plate planter, strip tillage with inclined plate planter and conventional tillage and hand planting. All the treatments were replicated thrice with RCB design. The planter was tested for sowing maize, wheat and mungbean during 2012-13. Bed planting, minimum tillage and strip till methods required 26%, 30% and 57% less energy and... |

| Bio-speckle can be used as a method for analysing the activity of biological materials illuminated with laser beam. Physically, bio-speckles are the result of scattering of coherent light on moving particles inside living tissue. Therefore, the aim of this study was to investigate bio-speckle activity in lemons and determine the age of the lemon fruit from the observation of its dynamic speckle pattern. The speckle pattern of laser light scattered in lemon fruits were measured through their quantification. For the quantification of the variation by bio-speckle, two different methods of image analysis were used: moment of inertia and the spatial temporal speckle correlation coefficient. The bio-speckle activities were also characterized by the line... |

| The main research aims to detecting the linear and nonlinear variability modeling in analyzing the variability patterns of rainfall series. For rainfall linear and nonlinear variability modeling, the ARIMA models and ARCH family models has been used for predicting the monthly and annual rainfall series extracted from IRIMO during 1975-2014 within 140 stations in Iran. Several ARIMA and ARCH (six models) models have been used and their validity has been confirmed by evaluating different accuracy indicators, using the hybrid model for the variability modeling. The analysis of ARIMA and GARCH selective models indicates existence of random and non-random in the rainfall time series. The combination model of (1, 0, 0) and GARCH (1, 1) is applied for the... |

| The present experiment was carried out to assess influence and inter-relationships of soil properties in grasslands of three wildlife protected national parks in Central India. Aboveground biomass samples of grass and soil samples were collected during different seasons based on specified measurement protocol by the state forest department. Aboveground biomass of grass demonstrated a characteristic growth pattern throughout the year, increased and achieved maximum biomass during at the end of rainy season (September), while started decreasing and attained minimum biomass during pre-summer (March) season. Mean aboveground biomass in the study regions was varied from 2.03 (Bandhavgadh National Park) to 5.44 Mg ha-1 (Kanha National Park) with an average... |

| The study was undertaken to assess the impact of prime movers (40 hp and 50 hp) and agricultural machinery (cultivator, disc harrow and rotavator) on soil compaction. Initially, the prime movers were operated at three speeds (2 kmph, 3 kmph and 5 kmph) for 1, 2 and 3 passes and responses were measured in terms of bulk density (gcm-3), particle density (gcm-3), porosity (%), cone index (kPa), infiltration rate (cmh-1), hydraulic conductivity (cmh-1) and particle size distribution (mm). The experiments were planned as per Randomized Block Design (RBD). It was observed that bulk density, particle density and cone index increased with an increase in the number of passes from 1 to 3. Maximum percentage increase of 5.82 % bulk density, 2.78 % particle density... |

| The effect of drying behaviour on the drying rate and quality characteristics of potato slices in a vacuum-infrared drying system was studied. In this research, the effect of the infrared radiation powers (100, 150, and 200 W) and vacuum levels (20, 80, 140 mmHg and atmosphere pressure) at different slice thickness (1, 2 and 3 mm) on drying rate and shrinkage percentage and rehydration capacity were investigated. It was concluded that infrared radiation power amount has a significant effect on processing time and drying rate. With increasing radiation power, drying time is reduced and consequently drying rate is increased. The drying rate curve of potato slices at initial drying time is in the ascending phase because of surface moisture evaporation and... |

| Several methods were developed to assess the flowability of bulk material. Jenike introduced flowability values toassess the flowability of bulk material like mineral raw material under given loads. A method developed by Carr usesseveral granulometric parameters to describe the flow properties without influence on the load. The aim of the own studywas to evaluate the recommendations of Jenike and Carr regarding to their application onto crushed grain. Thereforemeasurements with grainy and powdery grain products were carried out to determine flow properties regarding Jenike andCarr. Additionally unloading tests with a level model silo were performed to find out the influence of the outlet diameter.The evaluations of the flow properties according to Jenike... |
