the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...
In general, the ultimate goal of a sustainable system is to maximize the benefits of existing resources and to minimize the threats to the environment that occur due to the present conventional agricultural activities. Meanwhile, seed, as a rice cultivar in the present study, is presented as an important factor in sustainability. Therefore, identifying the most suitable cultivar of rice for sus...
India is the largest producer of rice (Oryza sativa L.) next to China in the world. Rice cultivation is a huge water demanding enterprise. In recent years, water table has depleted at a very rapid rate throughout the globe, thus, posing alarming threats and limiting the scope for cultivation of high water consuming crops especially rice. Challenges in maintaining the sustainability of rice farm...
Arbuscular mycorrhizal fungi (AMF) in an agricultural ecosystem are necessary for proper management of beneficial symbiosis. Here we explored how the patterns of the AMF community in rice roots were affected by rice cultivation systems (the system of rice intensification [SRI] and the conventional rice cultivation system [CS]), and by compost application during growth stages. Rice plants harves...
In order to integrate web with crop growth simulation and decision-making support system, the field experiment of different basal levels was carried out in experiment area of Jiangsu Academy of Agricultural Sciences in 2005 adopting 4 cultivars such as “Wuyungeng 7”, “Yangdao 6”, “Yueyou 948” and “Nangeng 41”, which mainly were used in collecting cultivar parameters and updating database of the...
one of the most important aspects of sustainable development is sustainable agriculture. therefore, nowadays, achieving a sustainable agricultural system is an important policy in agriculture department of countries. the main objective of this study is identifying factors affecting stability of rice cultivation in the city of shirvan and chardavol in ilam province. this study was a survey and i...
Rice is the staple food in Tamil Nadu and is grown in an area of 2.6 Mha with a production of 8.19 Mt and productivity of 3.2 t/ha. In the context of high water demand by rice farmers, any strategy that would produce higher rice yield with less water is the need of the day. One such system is “System of Rice Intensification” (SRI), which was developed by Fr. Henri de Laulanie in Madagascar in 1...
BACKGROUND Rice-duck cultivation is the essence of Chinese traditional agriculture. A scientific assessment of the mechanism and its capacity is of theoretical significance and practical value in improving modern agricultural technology. RESULTS The duck's secretions, excreta and their treading, pecking and predation decrease the occurrence of plant diseases, pests and weeds, enrich species d...
Cultivation of legume species as the second crop in rotation with rice and using plant growth promoting bacteria can be a good approach to improve rice production sustainability. This experiment was carried out to evaluate the effect of plant growth promoting bacteria on accelerating vegetative growth of crimson clover (Alborz 1) and rice (Hashemi) yield in a rice-based cropping system. A facto...
2-bromoethanesulfonate (BES) is a structural analogue of coenzyme M (Co-M) and potent inhibitor of methanogenesis. Several studies confirmed, BES can inhibit CH4 prodcution in rice soil, but the suppressing effectiveness of BES application on CH4 emission under rice cultivation has not been studied. In this pot experiment, different levels of BES (0, 20, 40 and 80 mg kg-1) were applied to study...
