Impact of Climate Warming on Cotton Growth and Yields in China and Pakistan: A Regional Perspective

Year to year change in weather poses serious threats agriculture globally, especially developing countries. Global climate models simulate an increase global temperature between 2.9 5.5 °C till 2060, and crop production is highly vulnerable warming trends. Extreme causes a significant reduction yields by negatively regulating the phenology. Therefore, evaluate impact on cotton (Gossypium hirsutum L.) management practices, we quantified agrometeorological data of 30 years applying multiple modelling tools compute expected rise temperature, phenology, yield loss, provision agrometeorology-services, agronomic technologies, adaptation climate-smart agriculture. Model projections 15 agrometeorology stations showed that growing duration sowing-boll opening sowing-harvesting stages was reduced 2.30 5.66 days decade?1 4.23 decade?1, respectively, Pakistan. Temperature China also advanced planting dates, sowing emergence, 3–5 leaves, budding anthesis, full-bloom, cleft-boll, boll-opening, boll-opening filling 24.4, 26.2, 24.8, 23.3, 22.6, 15.8, 14.6, 5.4, 2.9, 8.0 days. Furthermore, present findings exhibited effect sowing-harvest time observed 2.16 premature, delayed for 8.2, 2.4, 5.3 1970s, 1980s, 1990s China. APSIM-cotton quantification revealed sowing, flowering, maturity were correlated with ?2.03, ?1.93, ?1.09, ?0.42 °C?1 average, respectively. This study provided insight into smart better improving agrotechnological services.
