Ever increasing population of the globe and use of productive agricultural lands for housing has posed serious threat to future food supply. Low productivity of wheat due to different management practices is a serious problem. Different wheat cultivars are sown in Pakistan in same conventional row spacing ignoring their tillering potential. Optimizing row spacing for different wheat cultivars differing in tillering capacity improves the productivity and thus minimizing the future food shortage risk. Low tillering cultivars sown in narrow row spacing give higher outputs compared with wider...
