Post-harvest operations are assuming importance due to higher yields and increased cropping intensity. Harvesting is important as the crop is reaped early to make way for another crop. It sometimes coincides with heavy rainfall or severe cyclone and floods. Therefore, suitable technology is necessary for reducing time and safe storage at the farm level. The post-harvest losses are estimated to be about 25 per cent.

7 Smokable Plants You Can Grow That Aren’t Marijuana
Quite a few plants may be safely, and pleasurable, lit up in a pipe or rolling papers. Those listed below are legal, unregulated, and totally safe to use. They are also non-hallucinogenic and non-addictive – perhaps that explains their lack of popularity? While they won’t get you high, when blended according to the instructions below, …

Adaptation to Climate Change
Adaptation refers to adjustment in natural or human systems in response to actual or expected climate stimuli, or their effects. Adaptation can be Autonomous or planned Autonomous: Those adjustments that are carried out without knowledge of climate change. Planned: Planned adaptations are those made deliberately in order to express climate change impacts. In Pakistan most of the …
Specific Effects of Climate Change on Agriculture with special reference to Pakistan
Specific Effects of Climate Change on Agriculture with special reference to Pakistan (1) Increase in Temperature in arable areas (Threats to food security) Duration of crop growth cycle are related to temperature. An increase in temperature will speed up development. In case of an annual crop, the duration between sowing and harvesting (growing season length …
Specific Effects of Climate Change on Agriculture with special reference to Pakistan
(1) Increase in Temperature in arable areas (Threats to food security) Duration of crop growth cycle are related to temperature. An increase in temperature will speed up development. In case of an annual crop, the duration between sowing and harvesting (growing season length GSL) will shorten, which will affect productivity. Heat stress at critical reproductive …
POSSIBLE IMPACTS ON AGRICULTURE
Agriculture is open to environment and depends heavily on it. Effect on crops: Maize crop in southern Africa may decrease by 30% of its main crop by 2030, in South Asia rice, millet and maize may decrease by 10%. Effects in different climatic zones: In tropical and sub-tropical regions, crop yield may decrease due to …

January 2016 Was the Most Abnormally Warm Month Ever Recorded, NASA Says
Hottest January On Record Meteorologist Danielle Banks discusses how a NASA study revealed that January 2016 is the hottest January on record. January 2016 was not only Earth’s warmest January on record, but also featured the largest warm departure from average for any month, according to two separate analyses released this week. The first month …

Climate Change and Green House gases
Change in steady state temperature of earth by the presence of atmosphere containing greenhouse gases (CO2, Methane, Nitrous oxide, Ozone, halocarbons (CFC + Hydro CFC), Water vapours/ clouds) that absorb radiation. Any systematic change in the long-term statistics of climate elements sustained over several decades or longer (The American Meteorological Society) Thus when climate for …
Weather and Climate
Weather: The actual state of the atmosphere at a particular time. We refer to weather when we say that the low and high temperature on 10 June 2015 at the University of Agriculture Peshawar were 22oC and 40oC, respectively, and there was no rain Climate: The weather condition averaged over a longer period of time usually …
