Agricultural Reseaerch Council, Ayub Agricultural Research Institute, Faisalabad, Pakistan
during 2019. Countries wise time series data of exported fruits and vegetables were taken
from AMIS for finding instability of commodities and countries. Current study focused on the
compound annual growth rates of production, export quantity and value of mostly exported
fruits and vegetables. Growth trends of selected commodities were executed by using semitrend growth model. Coefficient of variation technique was used to find out instability of specific
commodity for specific country/market. Selected exported vegetables (potato, tomato, onion
and garlic) indicated instability results for Sri Lanka, Malaysia, Qatar and Indonesia among
given markets and within the given period. Among fruits kinnow export shared 24.96, mango
export results showed 22.08 percent share in total fruits export followed by 13.55 percent share
of orange and 8.6 percent export share of dates dried in total export from Pakistan. Results
observed for instability of exports to countries, minimum value of coefficient of variation (24.34
percent) was recorded for Bahrein market for kinnow export and Bahrein market was stable
among given markets. Similarly, mango results showed that export of mango to Germany market
was stable among given markets and within the given period. Export of orange to Saudi Arabia
market and export of dates to Bangladesh market was stable among given markets within the
given period of time. Finally, in order to lessen the instability, it can be proposed that Pakistan
ought to take steps to boost the exports of primary commodity and value added products to raise
revenue profitable.

Advances in the adoption of conservation practices requires a better understanding of the agronomic context for cropping systems. This paper tests hypotheses about how agronomic and knowledge barriers influence the adoption of conservation practices for N management in orchard agroecosystems. Agronomic barriers are characterized by farm size, irrigation systems and access to water resources, and knowledge barriers are influenced by the availability of information and use of information sources. Our study focuses on the California’s San Joaquin Valley where we collected 879 in-person surveys from fruit and nut growers focused on ten different conservation practices related to fertilizer use, irrigation and soil health. We used logistic regression models to identify parameters influencing adoption and differences in adoption between fruit and nut growers. Our results indicate that overall growers report higher adoption for practices for fertilizer use compared to irrigation and soil health. Growers with larger parcels, microirrigation and more water security had a higher probability of practice adoption. Nut crops are more agronomically intense than fruit crops requiring higher rates of N fertilizer and water use. Nut growers adopted significantly more practices than fruit growers, and also utilized significantly more information sources and experienced significantly fewer practice challenges. Our results collectively support our hypotheses that agronomic and knowledge barriers differ between fruit and nut growers, and help to explain the variance in adoption of conversation practices in orchard agroecosystems. Furthermore, the significance of our work offers a case study for other regions and agroecosystems to address the need for linking agronomic and knowledge barriers to adoption in an effort to promote global climate-smart and regenerative agriculture initiatives.
