An integration of technology with crop yielding prediction methodology brought a major transformation in the production level globally. Machine learning concept has boosted that such manner further optimized situation farmer and agricultural industry. The combination different types algorithm enhances competency technological device to where becomes very effective least deviation can be expecte...
India's dependence on a climate sensitive sector like agriculture makes it highly vulnerable to its impacts. However, agriculture is highly heterogeneous across the country owing to regional disparities in exposure, sensitivity, and adaptive capacity. It is essential to know and quantify the possible impacts of changes in climate on crop yield for successful agricultural management and planning...
This paper examines the contribution of women’s labour input to productivity and efficiency in crop farming using a large survey dataset of 1,839 households from 16 villages in two agroecological regions of Bangladesh. Results reveal that female labour accounts for a substantial 28% of total labour use (mainly supplied from the family) and contributes significantly to productivity as well as te...
Many weeds interfere with the productivity of wheat and other winter annual crops; however, one common weed Medicago denticulata, appears to have a beneficial effect. An experiment was conducted at Agricultural Experimental Farm of the Indian Statistical Institute, Giridih, Jharkhand to observe the effect of M. denticulata (a legume) on different crops yield of barley (Hordeum vulgare Sensu lat...
The world's crop productivity is stagnating whereas population growth, rising affluence, and mandates for biofuels put increasing demands on agriculture. Meanwhile, demand for increasing cropland competes with equally crucial global sustainability and environmental protection needs. Addressing this looming agricultural crisis will be one of our greatest scientific challenges in the coming decad...
The world population is projected to become a staggering 8.3 billion by 2030 from about 6 billion today, which will aggravate food insecurity especially in developing countries [31]. By 2050, developing countries will account for 93% of cereal and 85% of meat demand growth [73]. In agricultural crop production systems, insects, diseases and weeds continue to threaten sustainability and account ...
background and objectives: although more than 90 percent of consumed water used in agricultural sector, water is the major limiting factor for agricultural development in iran. over the past few years increasing agricultural crop water productivity thorough deficit irrigation methods has been studied by agricultural researchers and planners. although lorestan province is one of the major produc...
This study evaluates the potential impact of improved agricultural technologies on smallholders’ crop productivity and welfare. We use household-level data from Ethiopian Rural Household Survey collected by IFPRI in 1989-2009. The survey covers around 1500 rural households drawn from four regions and 15 rural villages. Endogenous treatment effect model is employed to account for the selection b...
Agricultural Drought is characterized by a deficient supply of moisture, resulting either from sub-normal rainfall, erratic rainfall distribution, or higher water with respect to a crop. In spite of technological developments in providing improved crop varieties and better management practices, in India, agriculture has been considered a gamble due to higher spatial and temporal variability. Th...
Convincing data now show that temperatures are increasing, and that changing precipitation patterns are already affecting agriculture. Predicted future impacts vary by region, but all are projected to suffer productivity declines by the late twenty-first century unless successful mitigation measures are implemented soon. Exacerbating the climate change challenge, doubling of overall crop produc...
