Leaf being the essential economic part in tobacco, the number of leaves per plant, leaf area Index and net leaf dry matter production per unit area are the deciding factors in realizing higher productivity. Drought/moisture stress can substantially decrease the number of leaves, leaf thickness and expansion of individual leaf resulting in lower productivity and poor quality. Nearly two thirds of the tobacco growing areas in KLS falling under dry and semi-dry regions have been periodically experiencing drought/moisture stress severely affecting the sustainable productivity and quality. Field Experiments and large...
