Abstract
The present investigation entitled “Effect of irrigation methods and planting dates
on yield of potato (Solanum tuberosum L.)” was studied at Research farm of Department of
Vegetable Science, CCS HAU, Hisar during the year 2017-18 and 2018-19. Among different
irrigation methods, micro-sprinkler irrigation method (I2) significantly enhance total tubers
yield of potato (230.0 and 252.2 q/ha harvested at 75 DAP and 246.1 and 295.2 q/ha
harvested at 90 DAP) over furrow irrigation method, whereas, among different dates of
planting, 15th October (D4) gave significantly maximum total tubers yield of potato (341.6
and 363.4 q/ha harvested at 75 DAP and 383.2 and 417.3 q/ha harvested at 90 DAP) over rest
of the other planting dates during 2017-18 and 2018-19, respectively. While comparing the
interaction between irrigation method and date of planting, maximum yield of potato was
observed in treatment D4I2 and comparing the combinations of different dates of planting with
different methods of irrigation, maximum total tubers yield of potato (349.0 and 371.8 q/ha
harvested at 75 DAP and 392.3 q/ha and 435.8 q/ha harvested at 90 DAP) were recorded in
treatment D4I2 (where potato planted on 15th October under micro-sprinkler irrigation) which
was statistically at par with D4 I1 (334.3 q/ha) during 2017-18 harvested at 75 DAP and D4 I1
(414.8 q/ha) during 2018-19 harvested at 90 DAP but potato planted on 15th September and
harvested at 75 DAP with micro-sprinkler irrigation method to be a good substitute for
existing planting dates and duration, which gave highest benefit cost ration (due to high price
of fresh potato) under Hisar conditions.
