“…It is contradicting to various studies which have shown a positive effect of increased rainfall on agricultural productivity (Kumar et al, 2021). Further, the negative impact can be observed due to an increase in rainfall during the ripening stage (Abbas & Mayo, 2021). Due to heavy rainfall in the month of August in Meghalaya shows a significant and -0.46% impact on rice (Dkhar et al, 2017) and an increase in rainfall from 5% to 15% in the month of September-October has negatively impacted rice yield in Punjab (Mahmood et al, 2012).…”

“…The findings of the paper can be supported by various national, regional and international empirical estimations. As the countries possessing similar characteristics to India like Pakistan & Bangladesh have shown that an increase in the minimum temperature in Pakistan has positively affected the rice yield due to the growth of crop at the replantation stage during the vegetation phase, and in Bangladesh, its impact is neutral on different varieties of rice (Abbas & Mayo, 2021;Chowdhury & Khan, 2015). Whereas in China, the exact opposite results can be observed where the minimum temperature has shown a negative impact on yield although insignificant, and it happens due to an increase in respiration loss during night time (Zhang et al, 2010).…”

“…Further, maximum temperature and rainfall are affecting rice negatively by 3.87% and 0.034% but insignificantly. The reason for the negative impact might be due to a decrease in the number of plants at the ripening stage, tillering or stem elongation stage (Abbas & Mayo, 2021) and heavy rainfall in the maturity stage (Mahmood et al, 2012).…”

The present study aims to examine the impact of climate change on wheat and rice yield of the Punjab state of India. Using district-level panel data from 1981 to 2017, the study employs fully modified ordinary least squares (FMOLS), dynamic ordinary least squares (DOLS), and pooed mean group (PMG) approaches. The Pedroni cointegration has established a long-run relationship of climate variables with rice and wheat crops. The results of FMOLS and DOLS show that minimum temperature has a positive effect on both wheat and rice, while maximum temperature is found to be negatively contributing to both the crops. Rainfall has a significant adverse effect on wheat yield. Seasonal rainfall has been detrimental to wheat and rice yield in the study period, indicating that excess rainfall proved counterproductive. Pooled mean group (PMG) model confirms the robustness of the results obtained by FMOLS and DOLS techniques. Moreover, Dumitrescu-Hurlin causality test has revealed a unidirectional causality running from minimum temperature, rainfall & maximum temperature to rice and wheat yield. The findings of the study suggest that the government should invest in developing stress-tolerant varieties of wheat and rice, managing crop residuals to curb further environmental effect and sustain natural resources for ensuring food security.

“…the reproductive phase. According to Abbas and Mayo ( 2020 ), increased rainfall during the flowering stage shows a negative relationship with rice production. This is mainly due to the effects of sediments in muddy water which block the pores and hampers respiration and photosynthesis, thus resulting in reduced production of the crop (Balasubramanian et al 2004 ).…”

In recent decades, nano-scale zero valent iron is reported to have plant growth enhancement capacity under laboratory conditions, but till date, there is no report to highlight its effect on the growth and yield of field-grown plants. In this study, we have evaluated the potential of nZVI priming on rice yield. A two-year field study has been conducted with different concentrations (10, 20, 40, and 80 mg l −1 ) of nZVI for seed priming. The efficacy of nanopriming was compared with the hydroprimed control set. Seeds were treated for 72 h and sown in nursery beds and after 30 days seedlings were transplanted in the field. Root anatomy and morphology were studied in 7 days old seedlings where no changes were found. RAPD analysis also confirmed that low doses of nZVI were not genotoxic. Nanoprimed plants also had broader leaves, higher growth, biomass, and tiller number than control plants. Maximum yield was obtained from the 20 mg l −1 nZVI primed set (3.8 fold higher than untreated control) which is achieved primarily because of the increase in fertile tiller numbers (two fold higher than untreated control). Higher values of other agronomic parameters like growth rate, net assimilation rate proved that nZVI priming enhanced photosynthetic efficiency and helped in the proper storage of photo-assimilates. All these attributed to increased accumulation of phytochemicals like starch, soluble sugar, protein, lipid, phenol, riboflavin, thiamine, and ascorbic acid in the grains. The elemental analysis confirmed that nZVI priming also promoted higher accumulations of macro and micronutrients in grains. Thus, nanoprimed seeds showed better crop performance compared to the traditional hydropimed seeds. Hence, nZVI can be considered as ‘pro-fertilizer’ and can be used commercially as a seed treatment agent which is capable of boosting plant growth and yield along with minimum interference to the soil ecosystem.

Identifying the temperature change at a regional level is one of the essential parameters to determine the intensity of climate change. The current investigation provides an examination of changing trends of temperature in the Punjab province from 1970 to 2019. Sen's slope estimator method is applied to monthly data of mean temperature (Tmean), maximum temperature (Tmax), and minimum temperature (Tmin) to calculate the rate of temperature change. Statistical methods were used to find out the level of significance in terms of negative or positive trends to examine the variability among various weather observatories. Moreover, predicted values have also been observed for a detailed analysis of temperature variability and trends. Significant and pronounced changes in the mean temperature (T mean) are distinguished all over the Punjab regions with an increasing trend from North to South Punjab. In the case of maximum temperature (Tmax), a faster rate of rising in temperature is observed over the Southern and Western regions of Punjab. In contrast, the minimum temperature (Tmin) shows an increasing trend in Central Punjab. The findings provide detailed insight to policymakers for the planning of mitigating efforts and adaptation strategies in response to climate change.
