“…The increase in temperature results in decrease in yield over this region. The present study being observational based, found that during kharif season, the decrease in average temperature occurred until July agreeing with the findings of Krishnan et al (2007). However, the subsequent rise was found to be until September instead of October as demonstrated by Krishnan et al (2007) though ~ 0.9 °C difference in temperature observed between the mean values of these 2 months (Fig.…”

“…Though temperature-specific analysis is relatively less, few studies like that of Krishnan et al (2007) emphasized upon the impact of temperature on rice yield by taking into account various stages of growth. According to this study, temperature is usually on higher side during the sowing stage followed by a decrease in average temperature in the tillering stage and increase in temperature is observed during panicle initiation and flowering stage.…”

A Study on Land Suitability for Rice Cultivation in Khordha District of Odisha (India) Using Remote Sensing and GIS

With the global population on the rise, it is important to address the increasing demand for food. According to FAO (Food and Agriculture Organization, United Nations), by 2050, the developing countries must double their food production to meet the growing demand. Proper land utilization can be one of the solutions for this problem. In view of this, the current study focussed on land suitability analysis for Khordha district of Odisha (India) for rice crop. This study estimated that the amount of land suitable for rice cropping was 195,731 ha against the currently cultivated land of 122,183.38 ha. Therefore, there was a possibility of more amount of land that could be available for rice cultivation in Khordha district than the currently cultivated area. In order to perform this exercise, the land use and land cover data from IRS (Indian remote sensing satellite), soil nutrient parameters like pH values and nitrogen, potassium, phosphorous and organic carbon contents were considered. In addition, the climatic parameters such as near surface temperature, rainfall and number of rainy days were taken into account. The unused land identified in Khordha district in this study might be utilized for cultivating rice crop in this region.

“…Field crops in particular have received considerable attention, with most research scenarios including a doubling of the atmospheric carbon dioxide concentration (Bertrand et al 2007;Kim et al 2007;Marhan et al 2008) and/or a temperature increase by 2 • C or more (Estrella et al 2007;Krishnan et al 2007;Xiao et al 2007), reflecting the most likely future climate estimates proposed by the Intergovernmental Panel on Climate Change (IPCC 2007) and other climate modeling efforts. Field crops, such as maize (Zea mays L.), wheat (Triticum aestivum L.) and rice (Oryza sativa L.) are by far the largest contributors to meeting the food energy demands of a growing human population.…”

Climate change effects on winter chill for tree crops with chilling requirements on the Arabian Peninsula

2009

Fruit production systems that rely on winter chill for breaking of dormancy might be vulnerable to climatic change. We investigated decreases in the number of winter chilling hours (0-7.2 • C) in four mountain oases of Oman, a marginal area for the production of fruit trees with chilling requirements. Winter chill was calculated from long-term hourly temperature records. These were generated based on the correlation of hourly temperature measurements in the oases with daylength and daily minimum and maximum temperatures recorded at a nearby weather station. Winter chill was estimated for historic temperature records between 1983 and 2008, as well as for three sets of synthetic 100-year weather records, generated to represent historic conditions, and climatic changes likely to occur within the next 30 years (temperatures elevated by 1 • C and 2 • C). Our analysis detected a decrease in the numbers of chilling hours in high-elevation oases by an average of 1.2-9.5 h/year between 1983 and 2008, a period during which, according to the scenario analysis, winter chill was sufficient for most important species in most years in the highest oasis. In the two climate change scenarios, pomegranates, the most important tree crop, received insufficient chilling in 13% and 75% of years, respectively. While production of most traditional fruit trees is marginal today, with trees barely fulfilling their chilling requirements, such production might become impossible in the near future. Similar developments are likely to affect other fruit production regions around the world.

“…Krishnan et al (2007) point out that limitations in rice production caused by extreme temperatures can be mitigated, at least in part, by changing the sowing time and selecting genotypes that produce more panicles per m 2 and with greater spikelet fertility. Another advantage of using cultivars responsive to the increase in the number of panicle per m There was interaction among cultivars, sowing times and crop sites for grain yield (Table 2).…”

Rice phenology and development are events controlled by environmental and genetic factors, and the yield potential of the crop is defined by their interaction. This study aimed at analyzing the performance of irrigated rice genotypes in contrasting ecosystems and their effects on morphophysiological characteristics. Two ecosystems (tropical and subtropical) were analyzed, as well as cultivars recommended for tropical (BRS Catiana and BRS Jaçanã) and subtropical (BRS Pampa, BRS 7 Taim and IRGA 424) regions. The experiments were arranged in a complete randomized block design, with four replicates, being the factors the genotypes, sowing times and sites. The phenological development, biomass dynamics, radiation use efficiency and grain yield were evaluated. The accumulated degree-days demand for flowering decreased faster in the tropical ecosystem than in the subtropical ecosystem for late sowing. The radiation use efficiency values were similar in the subtropical ecosystem and yield was high for all sowing dates. On the other hand, the tropical ecosystem showed a high variation for radiation use efficiency values and yield. The higher accumulation of degree-days and solar radiation during the reproductive and grain-filling phases contributed to increase yield in both ecosystems.
