Background: Continuous rice cultivation has a negative effect on sustainable production. Crop rotation can increase the yield and soil quality. This study aimed to provide information morpho-physiological fingerprints of cultivars in different crop systems. Methods: Twelve were evaluated terms their three systems, i.e., rice-rice-rice, maize-maize-rice (M-M-R) vegetable-vegetable-rice, at Agrot...

The production of conidia of entomopathogenic Beauveria bassiana by solid-state fermentation was studied for the development of a biocontrol agent against aphid Myzus persicae. The optimal conditions for conidia production on polished white rice were 40% moisture content, 25℃ culture temperature, 2-day-old seeding culture grown in 3% corn meal, 2% rice bran, 2% corn steep powder medium, initial...

Many cultivation practices have been improved in order to decrease environmental burdens of paddy rice production in Japan. Therefore, the importance of life cycle assessment (LCA) to assess the environmental impacts of whole production systems particularly that of rice production has increased. However, the applications of LCA to rice production are still limited, although rice is the staple f...

This study endeavors to evaluate the effects of farmers’ training program on the adoption of improved farming practices, the output of rice farming, and the income as well as the profit from rice farming by employing an ex-post non-experimental data in Sierra Leone. It was established that participating in farmers’ training program increased the possibility of adoption of the improved farming a...

The sustainability of rice productivity in Bangladesh is likely to face major threat due to water shortage during boro (winter season). The conventional transplanted boro rice requires huge amount of irrigation water due to wastage of various means. It is an imperative task that water saving production technology is needed to replace the conventional system for sustaining boro rice production i...

Italian rice production is progressively threatened by water scarcity. Some strategies have been developed to reduce water use. Nevertheless, reducing water irrigation amounts may lower paddy rice production. This publication compares the productivity and the economic performances of traditional and modern rice varieties in northern Italy using two different water management systems. The object...

Rice is one of the most important model crop plants whose heterosis has been well-exploited in commercial hybrid seed production via a variety of types of male-sterile lines. Hybrid rice cultivation area is steadily expanding around the world, especially in Southern Asia. Characterization of genes and proteins related to male sterility aims to understand how and why the male sterility occurs, a...

The distribution of nitrogenase activity in the rice-soil system and the possible contribution of epiphytic cyanobacteria on rice plants and other macrophytes to this activity were studied in two locations in the rice fields of Valencia, Spain, in two consecutive crop seasons. The largest proportion of photodependent N(2) fixation was associated with the macrophyte Chara vulgaris in both years ...

Natural resource base degradation, forest denudation, instability in crop production due to scarcity of water necessitates a thorough insight on sustainable agricultural development for conservation of natural resources not only for the present generation but also for the posterity. An attempt had been made to study the natural resource inventory of part of eastern plateau of India, using LISS ...
