Spatial Dependence of Physical Attributes and Mechanical Properties of Ultisol in a Sugarcane Field
This study investigates the effect of conventional tillage and application of the monoculture of sugar cane on soil health. Variables like density, moisture, texture, consistency limits, and preconsolidation stress were taken as indicators of soil quality. The measurements were made at a 120 × 120 m field cropped with sugar cane under conventional tillage. The objective of this work was to char...
متن کاملPhysical Properties of an Ultisol under Plastic Film and No-Mulches and Their Effect on the Yield of Maize
Film mulching is an important agricultural practices used to improve crop productivity. Field experiments were conducted using maize (Zea mays L. ) to determine the effect of film mulching on soil physical properties and maize yield in 2006 and 2007 cropping seasons. The experiment was a randomized complete black design (RCBD) with four film treatments viz. Black film (BM), white film (WM), Bla...

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 اولAgeing of Stored Rice: Changes in Chemical and Physical Attributes
Rice ageing is a complicated process, which involves changes in physical and chemical properties of the rice grain. Starch, protein and lipids are the main rice grain components which affect cooking and eating quality. While the overall starch, protein and lipid contents in the rice grain remain essentially unchanged during storage, structural changes do occur. These changes affect the pasting ...
متن کاملINVITED REVIEW Sustainable intensification in agricultural systems
†Background Agricultural systems are amended ecosystems with a variety of properties. Modern agroecosystems have tended towards high through-flow systems, with energy supplied by fossil fuels directed out of the system (either deliberately for harvests or accidentally through side effects). In the coming decades, resource constraints over water, soil, biodiversity and land will affect agricultu...
