CN- method was used to arrive at runoff volume which was converted into drainage coefficients. Drains were designed to carry these drainage volumes safely and quickly from the blocks to the outlets. To meet out the shortage of water during critical dry spells experienced during crop growth period, 4 Lift Irrigation Schemes (LIS) were proposed in the study to utilize the available flows in the rivulet during Kharif period and also during the initial phase of Rabi crop. Besides this surface water utilization was proposed to be increased by repair and maintenance of the existing diversion canal of Bharri Dam. Peak carrying capacity of the diversion canal was worked out to be 85 lps and the irrigation command of it is 32.5 ha. It was found that there are 42 no. of bore wells in which 32 is working and 10 bore wells is not working. The average discharge and water level fluctuation for 5 year period was found to be 5.8 lps and 12.35 m respectively. The potential of water resources was estimated. The available surface water and ground water during study period was found 0.71 MCM and 0.50MCM. Keywords: drainage, Rabi crop. Introduction Water is the most precious gift of nature. Drainage is the artificial application of removal excess water from land. Some land requires drainage before it is possible to use it for any agricultural production; other land profits from either practice to increase production. Some land of course does not need either. Although either practice may be or both often are used for nonagricultural purposes to improve the environment, this article is limited to their application to agriculture. Water productivity can be improved by choosing well-adapted crop types, reducing unproductive water losses and maintaining healthy, growing crops through optimized water, nutrient, agronomic management, irrigation and drainage plan. In general, improving agricultural water productivity, thus freeing up water for ecosystem functions, can be achieved by creating synergies across scales and between various agricultural sectors and the environment, and by enabling multiple uses of water and equitable access to water resources for different groups in society. Investigating and explaining the irrigation and drainage management indicators and their ability to define the status of a system to the system users is important. This applies to the Irrigation and drainage network systems in India. Without a proper understanding of the concept and relevance of such indicators, strengthening the network infrastructure with more and more interventions will not succeed in getting the desired benefit from such networks. This paper presents definition, measurement and practical application of water productivity. It is also widely accepted fact that there is no substitute for irrigated agriculture in terms of its production volume and drainage has a role to play here. The slogan of engineering science "No irrigation without drainage" can be extended: no sustainable agriculture without drainage. Materials and methods Study Area: Raipur district in located under the agro-climatic zone “Chhattisgarh plains” in the state of Chhattisgarh. The study area (IGKV farm Raipur) is situated 7 km away from Raipur district on Mahasamund road. The IGKV Raipur situated in 81 o 41′ 20′′ to 81 o 43′ 15″ E longitude 21 o 13′ 35′′ to 21 o 14′ 15′′ N Latitude at elevation is 285-295 meter (MSL) and area of IGKV is 200 ha and Climate is Sub-tropical, annual rainfall recorded (yearly) 1064.7mm. The exact location of study site is depicted in Fig. Agro climate: Chhattisgarh state has been divided into three Agro-climate zones namely Chhattisgarh plains, Baster Plateau and Northern hill zone covering 51.0%, 28.0% and 21.0% of the geographical area, respectively as per NARP classification.
