A field experiment was conducted at the experimental field, All India Coordinated Research Project on Dryland Agriculture, Biswanath Chariali centre, Biswanath College of Agriculture, Assam Agricultural University, Biswanath Chariali during the Rabi season of 2013-14 to study the "Efficiency of harvested rainwater on potato under rainfed condition". The treatment comprised of four irrigation levels in the main plot viz. No irrigation, one irrigation at 25 days after planting, two irrigation at 25 and 60 DAP, & three irrigation at 25, 60 and 80 DAP, in combination with two sub-plot of organic viz. no organic and with organic (i.e. vermicompost @ 2 t ha-1) treatment. These treatments were evaluated under split plot design with three replications. The finding revealed that harvested rainwater applied three times at 25, 60 & 80 DAP recorded the highest total tuber yield (22.69 t ha-1) over other irrigation levels. Application of organic in terms of vermicompost @ 2 t ha-1 significantly increased the tuber yield of potato (17.55 t ha-1) over non-organic treatment (15.87 t ha-1) by 10.59 %. Organic recorded the highest water use efficiency (188.85 kg ha-1 mm-1), which was 16.64 per cent higher over non-organic treatment. Though, irrigation at 25, 60 and 80 DAP with vermicompost gave the higher yield (23.39 t ha-1), yet the highest B:C ratio (2.17) was recorded in the treatment receiving harvested rainwater applied at 25, 60 and 80 days after planting under no organic treatment. Thus, it may be inferred that with a rainwater harvesting volume of 270.11 ha mm, an area of one hectare potato crop can be irrigated applying 233.14 mm irrigation in furrow system at 25, 60 and 80 days after planting with recommended dose of organic and inorganic fertililizers for obtaining economically viable tuber yield of potato under prevailing situations.
