determination of some physical and mechanical properties red bean
چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...
15 صفحه اولIntegrated nutrient management using deoiled Jatropha cake for sustained and economic food production
With growing environmental and energy concerns, Jatropha plantations are promoted in degraded/waste lands for the biodiesel production. Nutrient rich nonedible deoiled seed cake, a by-product of Jatropha left out after oil extraction was evaluated at the ICRISAT centre at Patancheru, India as an environment friendly source of nutrients for rainy season maize and soybean followed by postrain...
متن کاملEffect of Acidic Biochars on Some Chemical Properties and Nutrient Availabilities of Calcareous Soils
Low organic matter content and alkaline pH of calcareous soils in arid and semi-arid regions are the main reasons for the low nutrient availabilities for plants in these soils. One way to improve the chemical properties and fertility of calcareous soils is the application of organic substances such as biochar produced from pyrolysis of organic wastes. However, biochars have an almost predominan...
متن کاملRelationships between soil physicochemical, microbiological properties, and nutrient release in buffer soils compared to field soils.
The retention of nutrients in narrow, vegetated riparian buffer strips (VBS) is uncertain and underlying processes are poorly understood. Evidence suggests that buffer soils are poor at retaining dissolved nutrients, especially phosphorus (P), necessitating management actions if P retention is not to be compromised. We sampled 19 buffer strips and adjacent arable field soils. Differences in nut...
متن کاملElectrical and Physical Properties of Coimbatore Soils at Microwave Frequency
The aim of this paper was to study the variations of the electrical properties like electrical conductivity and dielectric constant of soils with their physical properties. Eight soil samples were collected from different locations of Coimbatore (Tamilnadu) at the depth of 0 – 15 cm. Soil samples were analysed for physical properties like texture, bulk density and porosity. The electrical condu...
