Abstract :
This study was conducted to determine the
effect of RWUE under different dates of planting and
mulching treatment during rabi, 2017-18 in the
Instructional-Cum-Research (ICR) Farm of Assam
Agricultural University, Jorhat. The variety – Kufri Jyoti
was grown in split plot design with 3 dates of planting
(P1- 10th Nov, P2- 20th Nov and P3- 30th Nov) in main plots
and mulches (M0- non mulch, M1- water hyacinth and
M2- black polythene) in sub-plots, following
recommended agronomic practices. Microclimatic
parameters like daily soil temperature (5 cm and 10 cm
depth) and soil moisture content at 10 days interval from
two depths (0 - 15cm and 15 - 30 cm) were recorded
throughout the period of experiment. A total of 98.1 mm
rainfall was received during the growing period and
weekly average BSSH ranged from 1.3 to 9.2 hr.
Irrespective of mulching treatments, the highest tuber
yield of 112.8 q/ha was recorded in first date of planting
(P1), which was reduced by 11.68 and 14.22 per cent in
second (P2) and third (P3) planting dates, respectively.
The obtained result indicated that highest tuber yield of
120.8 q/hawasrecordedunder water hyacinth, followed
by black polythene (103.5 q/ha) and non-mulched
treatment (85.0 q/ha). Increased in tuber yield under
water hyacinth was 42.12 per cent, while it was only 21.6
per centunder black polythene as compared to nonmulched condition. In potato cultivar Kufri Jyoti,
irrespective of planting dates and mulching treatments
the rain water use efficiency (q/ha/mm) varied from 2.72
to6.85 q/ha/mm with the overall mean of 4.60 q/ha/mm.
Irrespective of mulching treatments, the highest RWUE
was recorded in first date of planting (P1) and lowest was
recorded under second date of planting (P2) of 4.81
q/ha/mm.
