Human activities such as deforestation and cultivation contribute to the accumulation of carbon dioxide in the environment. Methane is emitted by energy exploration, coal mining, natural gas spills, waste, and waste dumps. Methane generated by such greenhouse gases has significantly contributed to the climate change and global warming. However, the most significant contributor to climate change and global warming is the use of fossil fuels. These fuels contribute to ozone depletion and global warming by emitting greenhouse gases into the atmosphere. The current study key objective was to determine the CO2 emission effect to key fruit production in Pakistan by taking time series annual data varies from 1970 to 2019. A non-linear autoregressive distributed lag model (NARDL) was employed to check the variables linkages. The consequences of short- and long-run estimates expose that the positive and adverse shocks of citrus fruit create expressively to upsurge the CO2 emission. Similarly, the positive and negative shocks of mango fruit expose an adverse interaction to CO2 emission. The positive shock of apple fruit has constructive but negative shock expose and adverse linkage to CO2 emission. Further, banana fruit also exposes a negative but constructive via positive shock linkage to CO2 emission. Moving towards the apricot fruit production that exposed a constructive linkage via positive and negative shocks to CO2 emission. The almond fruit productivity via positive and negative shocks exposed an adverse relation to carbon dioxide emission. Grape fruit via positive shock shows a construct, but negative shock exposed an adverse association to carbon emission in Pakistan. Finally the guava fruit production exposed a construct linkage to CO2 emission via positive and negative shocks. Since agricultural activities and CO2 emissions are essential to resolving the pollution problem, a series of practicable steps must be taken by the Pakistani authorities to tackle this issue.

Performance of seven apricot varieties (castle Bright, Sarbaghal, Narai, Gold Cort, Badami, NJA-13 and Habi) was evaluated at Horticultural Research Station, Soan Valley, Nowshehra, Khushab, Pakistan during the year 2010 to 2012. At fruit maturity, sensory and physio-chemical analysis was carried out. The results revealed that variety castle Bright topped in fruit colour with maximum prints (8.51) and orange yellow colour which is highly appreciated in local market and matures during second week of May. The data further depicted that maximum points for flavor were attained by three varieties simulataneously i.e. castle bright (8.50), Badami (8.50) and Sarbaghal (7.75) while taste of fruit was bettr in castle Bright and Badami (8.50 each). Castle bright also attained maximum fruit weight (45.75g) and fruit size (1867.67mm2) with minimum flesh stone ratio (5.27%) and more pulp. Maximum TSS was noted in variety Badami (17.25%) followed by Castle bright (17.1%) and Sarbaghal (16.25%). Variety sarbaghal also excelled in fruit yield (39.00 kg/plant) followed by Castle Bright (32.50 kg/plant). [ABSTRACT FROM AUTHOR]
