| dc.description.abstract | Field experiment was conducted during winter season, Nov to Feb (2003-2004 and 2004-2005) at Vegetable Research Centre of G. B. P. U. A. & T. Pantnagar, to study the effect of nutrients and irrigation on the performance of potato on a Mollisol, Haldi loam in potato variety (JW-160). The treatments consisted of three levels of irrigation i.e. Control (I0), irrigation at 30 days after planting(I1) and irrigation at 30 and 50 days after planting(I2) and five levels of nutrients i.e. Control (F0), Zn Cu Mn B (F1), N100P100K100 Zn Cu Mn B (F2),N150P100K100 Zn Cu Mn B (F3), N200P100K100 Zn Cu Mn B (F4).Results of present investigation revealed that the application of irrigation at 30 and 50 days after planting (DAP) with N200P100K100 Zn Cu Mn B had significant effect on growth, yield attributing characters nutrient concentration of plant and tuber and nutrient uptake of tuber. Soil properties viz. available nitrogen, phosphorus, potassium, Zinc, copper, manganese and Boron were improved by the irrigation and nutrient treatment imposed on potato crop. Highest water use efficiency found in control irrigation treatment and also maximum and minimum nutrient use efficiency found in control and N200P100K100 Zn Cu Mn B nutrient treatments. Correlation between tuber yield and soil properties highest in available phosphorus and correlation between tuber yield and growth and yield attributes was highest at 60 DAP shoot number. Thus, the results achieved from the present investigation overall demonstrated that application irrigation I2 and nutrient F4 treatment on potato crop increased tuber yield, it effect on soil properties, water use efficiency and nutrient use efficiency under the condition of Tarai region of northern India. | en_US |
