paddy straw is one of the most abundant agricultural by-products in tamil nadu, india. itcontains high amounts of cellulose and lignin. the fungal strains were isolated from naturally decomposingsites of paddy straw. eight fungal strains were isolated and later these eight fungi were used for finding outtheir potential for the degradation of lignin and cellulose content of paddy straw. among ei...

The main objective of this research is to develop a methodology for identifying different varieties of paddy seeds using morphological features. Morphological features are powerful tool which could separate the different varieties of seeds. Three varieties of paddy seeds are taken that are classified according to their morphological feature range. Image of paddy seeds was acquired by a canon di...

PADDY is an experimental free-text retrieval engine for the Fujitsu AP1000. Considerable development of PADDY has occurred since the work reported at the second CAP Workshop. Search patterns now include generalised regular expressions, set operations may now be applied to the results of searches, and proximity operators have been implemented. The speed of literal searches has been increased and...

Although bubble ebullition through water in rice paddy fields dominates direct methane (CH4) emissions from paddy soil to the atmosphere in tropical regions, the temporal changes and regulating factors of this ebullition are poorly understood. Bubbles in a submerged paddy soil also contain high concentrations of carbon dioxide (CO2), implying that CO2 ebullition may occur in addition to CH4 ebu...

The importance of controlled water supply is indispensable for the sustainability in low land paddy production, which varies enormously from region to region and country to country. What essential is the degree of importance given to the three elements of water management namely (i) resource management within the watershed (ii) conveyance to the crop fields and (iii) management within farm fiel...

The paddy soil-rice system has efficient nutrient replenishing mechanisms. Basic cations and silica are supplied by irrigation water, while biological fixation works as an inexhaustible source of N in the system, and phosphorus availability is enhanced under anaerobic conditions. This, along with almost perfect resistance to soil erosion, gives the paddy rice system high productivity as well as...

The purpose of this study was to determine the difference in income earned by Lowland Rice Farming with Power Threshers and combine harvesters South Sangatta Village, District. method data analysis technique used is quantitative through economic analysis: cost analysis, revenue an activity after from all respondents. research population paddy rice farmers. sampling purposive sampling, farmers w...

The growth of organic farming practices in the last few decades is continuing to stimulate the international debate about this alternative food market. As a p art of a PhD project r esearch about embeddedness in Alternative Food Networks (AFNs), this paper focuses on the promotional aspects of organic farms websites from the Madrid region. As a theoretical tool, some knowledge categories drawn ...

Paddy is one of major crops grown in China. Fractal dimension is an important parameter used to describe geometrical characteristics of many natural objects. The objective of this study is to investigate mathematical relationships between the fractal dimension and the yield of the paddy spike based on the fractal theory and the image processing technologies. The color images of paddy spikes wer...

No validated models in Europe are capable of simulating the environmental fate of pesticides under the specific conditions of rice fields. Rice water quality--vadose zone flow and transport (RICEWQ-VADOFT) is a model developed from the coupling of a surface runoff model (RICEWQ) and a vadose zone flow and transport model (VADOFT) for determining predicted environmental concentrations in paddy w...
