Viewing Climate Change Impact through Maize Varietal Sowing at Variant Intervals

Abstract

Climate change is one of the detrimental factors for plant growth. A change in temperature can lead to a high loss in crop productivity. Keeping the detrimental effect of climate change on plant growth and productivity, research was carried out to mitigate the climate effect on crop productivity. Ten maize hybrids and varieties were selected for the experiment and were sown on five different sowing times. The experimental analysis was carried out in Randomized Complete Block Design with split plots arrangement having three replications. Sowing times were allocated to main plots while varieties and hybrids were allotted to the subplots, respectively. The results revealed that different varieties and hybrid shows a different response to variant sowing times. Maximum plant height was recorded by SB-989, maximum biological yield was recorded by Azam variety while maximum grain yield was recorded by SB-909 hybrid maize cultivar. Similarly early sowing time 5 th June showed better results in terms of plant height, grain yield and biological yield. From the results, it was concluded that maize variety showed by sown on 5th June to attain maximum output in terms of yield and yield attributes.
