Abstract
The experiment entitled “Effect of irrigation methods and nitrogen levels and its application on
growth and yield of potato” was conducted at Research Farm of the Department of Vegetable Science
and in Laboratory of the Department of Soil Science, CCS Haryana Agricultural University, Hisar
during Rabi season of 2015-16 and 2016-17. To find out the effect of irrigation methods and nitrogen
levels on potato for getting higher yield as well as keeping quality of potato tubers. The potato variety
used for the investigation was Kufri Bahar. The treatments comprising of drip and furrow irrigation
methods and five recommended dose of nitrogen (60, 80, 100, 120 and 140 % of RDN) were laid out in
split plot design with three replications in plot size of 3.60 x 3.60 m2. The ten competitive plants were
selected randomly from each treatment to record data on various parameters, which were influenced
significantly by different irrigation method and nitrogen levels. The irrigation methods showed
significant differences in all the growth and yield parameters expect plant emergence, dry matter in
tubers in both the years. Whereas, dose of nitrogen had significant effect on all the parameters expect
plant height at 30 days after planting and number of shoots per hill during 2015-16 and 2016-17,
respectively.
The maximum value for plant emergence (%), plant height at 30, 60 and 90 days after planting
(cm), number of shoots per hill, foliage weight (kg/m2), biological yield (q/ha), marketable yield (q/ha),
total tuber yield (q/ha), yield of 50 to 75 g and more than 75 g size tubers per square meter (kg/m2),
number 50 to 75 g and more than 75 g size tubers per square meter, harvest index (%), nutrient use
efficiency (kg/ha/kg), water use efficiency (kg/ha/cm), dry matter content in tubers and foliage (%),
nutrient uptake by tubers and foliage (kg/ha) and soil nutrient (kg/ha) were recorded with 100 % of
RDN and drip irrigation.The highest benefit: cost was calculated with 100 % of RDN and drip
irrigation. Hence, 100 % of RDN with drip irrigation condition have shown the best treatment
combination for potato production under semiarid conditions of Hisar, Haryana.
