| dc.description.abstract | The present investigation was undertaken at Vegetable Research Centre of Govind Ballabh Pant University of Agriculture and Technology Pantnagar during rabi season of years 2010-11 and 2011-2012 to study the “Response of potato (Solanum tuberosum L.) to irrigation and mulching”. The experiment was laid out in Split Plot Design with three replications consisting total 18 treatment combinations of two factors viz., 3 irrigation levels viz. I1: 50 mm CPE, I2: 100 mm CPE and I3: 150 mm CPE and 6 mulch treatments viz. Black polythene mulch (25 μm), Sugarcane leaves mulch (2.5 cm thickness), Sugarcane leaves mulch (5 cm thickness), Paddy straw mulch (2.5 cm thickness), Paddy straw mulch (5 cm thickness) and Control (without mulch). The response of potato to irrigation and mulching treatments were measured in terms of quantitative expression i.e., plant emergence (%), plant height, number of haulms per hill, number of leaves per hill, grade wise number of tubers, total number of tubers, grade wise yield of tubers, total tuber yield and moisture utilization pattern i.e., soil moisture content at various depth of soil, water use efficiency and number of irrigation and water applied. Economics of the various treatments were also worked out. On the basis of the observations, it can be concluded that the response of irrigation at 50 mm CPE resulted better growth and yield of potato tubers. Sugarcane leaves and paddy straw mulch, irrespective their thickness was recorded more beneficial for growth attributes. Sugarcane leaves mulch (2.5 cm thickness) and paddy straw mulch (2.5 cm thickness) produced maximum number of tubers and gave higher yield of potato tubers than black polythene and without mulch. The moisture status was higher when irrigated at 50 mm CPE under sugarcane leaves mulch (5 cm thickness). Irrigation at 50mm CPE with organic mulch had more water use efficiency than inorganic mulch. One irrigation along with 30.09 mm depth of water applied under organic mulch found better results. On the basis of economics, both sugarcane leaves mulch (2.5 cm thickness) and paddy straw mulch (2.5 cm thickness) gave maximum gross returns, net returns and B:C ratio. | en_US |
