abstract present study used translog cost function for determining break point of paddy farms. requested data set include inputs’ prices and quantities, and production amounts had been acquired from 500 rice farmers of guilan province at 2009. model used in this study is seemingly unrelated regressions (sur). the results showed that labor and pesticides had the highest and lowest share of produ...
The changes and relationship of climate parameters late-rice yield per unit area during the growth periods from 2010 to 2019 were quantitatively analyzed in order provide scientific guidance for countermeasures against change sustainable production late-rice. include cumulative daily sunshine hours (S), mean temperature (T), precipitation (P), relative humidity (H), highest lowest temperatures ...
Climate in its spatial and temporal inconsistency is one of the chief causes for determining agricultural productivity in a region. Climatic impacts should be kept into mind while developing long term agricultural policies. This study aimed at investigating the change in rice production in Pakistan from 1989-2009 using the GIS techniques and the impacts of climate change on rice production. Pak...
Rice yield is greatly affected by environmental stresses such as drought and salinity. In response to the challenge of producing rice plants tolerant to these stresses, we introduced cDNA encoding the transcription factors DREB1A and DREB1B under the control of the stress inducible rd29 promoter. Two different indica rice cultivars were used, BR29, an improved commercially cultivated variety fr...
26 A glass house study was conducted to investigate the accumulation of arsenic in tissues of five 27 widely cultivated rice (Oryza sativa L.) varieties of Bangladesh namely BRRI dhan 28, BRRI dhan 28 29, BRRI dhan 35, BRRI dhan 36, BRRI hybrid dhan 1. Arsenic concentrations were measured in 29 straw, husk and brown and polish rice grain to see the differential accumulation of arsenic among the...
Rice (Oryza sativa L.) is the main staple cereal crops for half of world’s population which predicted to exceed 9 billion by 2050. production needs be doubled meet future demand rice eating countries. To ensure food security growing population, sustainable needed. achieve expected yield, better understanding root systems will required. A panel cultivars, collected from Bangladesh Research Insti...
Rice (Oryza sativa L.) is the world’s most important cereal crop. The Doairgura variety (O. a low-yielding, high-quality aromatic rice-producing in Bangladesh. This study was undertaken to develop an vitro regeneration protocol through callus induction. MS media supplemented with different concentrations of 2, 4- D (0.5, 1.0, 2.0 and 3.0 mg /l) were used for induction from mature dehusked rice ...
Lean manufacturing is a systematic approach to identifying and eliminating wastes (non-value added activities) through continuous improvement by conveying the product at the pull of the customer in pursuit of production. In a more basic term, more value with less work. Since lean manufacturing eliminates many of the problems associated with poor production scheduling and line balancing, lean ma...
Soil fertility and rice production were the most frequently mentioned issues identified not only in all countries of Asia but also rest world. Hence, it is essential to pay attention for sustainable production, climate-smart agriculture soil health. Accordingly, assessments selected health indicators, such as, pH, organic matter cation exchange capacity (CEC) 17 Upazilas Cumilla district Bangla...
Seed priming has proved to be an effective pre-germination seed invigoration technique for different crops improve and seedling performance under abiotic stresses. In Bangladesh, winter rice is very often exposed cold waves just after sowing in the nursery bed resulting poor germination emergence, yellowish thin seedlings production, a low survival rate. may mitigate stress during emergence hel...
