\textbf{Abstract}
\begin{abstract}
\normalsize{
The continuation of same cropping patterns over the last three decades with inefficient and indiscriminate use of natural resources as well as agro"=chemicals inputs have resulted into mounting environmental problems.  Therefore the study of utilisation pattern of land, water and agro"=chemicals in perspective and to formulate suitable farm plans for sustainable production was undertaken. 



The data with regards to land use pattern, irrigation water, cropping pattern etc. were scanned from various published sources. Linear Programming Technique (LPT) was employed to make rescheduling of resources on sustainable lines. 



The results of the study reveal that area under forests does not indicate any appreciable increase over the years. The cropping pattern exhibited the acreage concentration of resource exhaustive and less risky crops like cotton, wheat and rice and most of irrigation water were used amongst these crops. Increased consumption of nitrogenous fertilisers and pesticides, continuation of same cropping pattern over the time period resulted into accentuating the area under problematic soils, depletion of underground water, infestation of weeds, insect"=pests and diseases. The optimal sustainable production plans showed increase in gross returns as well as accrued benefits through saving the water and agro"=chemicals. The optimal plans in incorporated the crop enterprises like green gram, black gram, soybean, cluster bean etc. not only improved the soil health but also reduction in use of natural resources and agro"=chemicals. The optimal plans further make sure to accommodate the economic, ecological and social aspects paving the path for sustainable development in agriculture. The agro"=climatic zone wise planning of agriculture is also essential for sustainability of crop production.}
