15 صفحه اولThe Effect of Phosphorus Fertilizer Rate and Application Time on Rice Growth and Yield
Three studies have been conducted since 2001 to examine rice growth, nutrition, and yield response to phosphorus (P) application rate and time. The three sites represent high-pH silt loam soils (>7.5) with a range of Mehlich 3-extractable P (8 to 41 mg P/ kg). The objective of this research was to measure rice biomass and tissue-P concentration during the growing season and rice grain yield res...
متن کاملRice Classification and Quality Detection Based on Sparse Coding Technique
Classification of various rice types and determination of its quality is a major issue in the scientific and commercial fields associated with modern agriculture. In recent years, various image processing techniques are used to identify different types of agricultural products. There are also various color and texture-based features in order to achieve the desired results in this area. In this ...
متن کاملMeasurement of Vertical Water Percolation Through Different Soil Textures of Paddy Field During Rice Growth Season
The water percolation loss beyond root zone in the soil is one of the important parameters to determine water requirement of rice plant. If the amount of water percolation rate into the soil is estimated more carefully, determination of water requirement will be evaluated better and designing for system of irrigation, drainage and related establishments will be more easily done. The purpose of ...
