“…High temperature may affect the pollen viability and fertilization which result in large yield reduction in maize (Jones and Thornton, 2003;Lobell et al, 2008;Rowhani et al, 2011). Among different hybrids, YH-1898 produced maximum grain yield (9443 kg ha -1 ) which was statistically similar to KJ.…”

Each genotype has an optimum range of temperature for growth and development, when the temperature increases beyond this critical limit, it generates temperature stress which affects its performance adversely. The aim of the study was evaluate the variation exists among genotypes regarding heat stress, 25 maize hybrids were tested at Maize and Millets Research Institute, Yusafwala-Sahiwal, Pakistan. The studies were focused on screening for heat tolerant maize hybrids that are adaptable in agro-climatic conditions of Pakistan. Results indicate that the all the maize hybrids were significantly affected by high temperature stress. Maize hybrids YH-1898, KJ. Surabhi, FH-793 ND-6339 and NK -64017 showed reasonable tolerance against high temperature and they produced higher grain yield per unit area as compared to other maize hybrids.

“…Studies have revealed that the poor performance of the agriculture sector is attributed to over dependence on rain-fed agriculture as well as increasing erratic climate change and variability (Ehrhart and Twena, 2006;Enfors and Gordon, 2008;Müller et al, 2011). Moreover, previous studies by (Mwandosya et al, 1998;Agrawala et al, 2003;IPCC, 2007;Thornton et al, 2009Thornton et al, , 2010Ahmed et al, 2011;Arndt et al, 2011;Rowhani et al, 2011) have indicated that, the future climate change and variability may present even more serious challenges on agriculture sector in Tanzania. The Intergovernmental Panel on Climate Change (IPCC, 2007) has emphasized that in developing countries, including Tanzania, by 2020, between 75 and 250 million of people are predicted to be exposed to increased water stress due to climate change.…”

“…Therefore, examining the nature of the relationships on a finer spatial scale is essential to properly assess the impacts of climate change and to instigate suitable adaptation measures. Most studies reported in the literature are on coarser spatial resolution, often on global, regional and nation scales (e.g., Parry et al 2004;Rowhani et al 2011;Lobell et al 2011).…”

Climate trends and impacts on crop production in the Koshi River basin of Nepal

Understanding crop responses to climate is essential to cope with anticipated changes in temperature and precipitation. We investigated the climate-crop yield relationship and the impact of historical climate on yields of rice, maize and wheat in the Koshi basin of Nepal. The results show significant impact of growing season temperature and precipitation on crop production in the region. Rice, maize and wheat cultivated at altitudes below 1,100, 1,350 and 1,700 m amsl (above mean sea level), respectively, suffer from stress due to higher temperatures particularly during flowering and yield formation stages. Responses of crop yields to a unitary increment in growing season mean temperature vary from -6 to 16 %, -4 to 11 % and -12 to 3 % for rice, maize and wheat, respectively, depending on the location and elevation in the basin. In most parts of the basin, we observe warming trends in growing season mean temperatures of rice, maize and wheat over the last few decades with clear evidence of negative impacts on yields. However, at some high-elevation areas, positive impacts of warming are also observed on rice and maize yields. If the observed trends in temperature continue in future, the impact is likely to be mostly negative on crop production in the basin. However, crop production may gain from the warming at relatively higher altitudes provided other conditions, e.g., water availability, soil fertility, are favorable.
