Description M.Sc. Dissertation
A field experiment was conducted during Rabi 2011-12 at the experimental farm
of CSKHPKV, Palampur, Himachal Pradesh to study the “Effect of plastic mulching,
planting methods and fertility levels on yield and quality of potato (Solanum tuberosum
L.)”. The experiment was laid out in split plot design with three replications. The main
plot consisted of three different mulching (black polyethylene mulch, transparent
polyethylene mulch and no mulch) and two planting methods (Ridge method and flat bed
method) whereas sub plot had three fertility levels (75% NPK, 100% NPK and 125%
NPK). Application of black polyethylene mulch resulted in highest tuber yield (316.6 q
ha-1) as well as net returns (Rs. 230446) and net returns per rupee invested (2.67) than
transparent polyethylene and no mulch. Planting potato crop in ridge method gave higher
tuber yield (289.2 q ha-1), net returns (Rs. 224283) and net returns per rupee invested
(3.45) than flat bed method. Increase in graded fertility levels from 75% to 125% NPK
improved growth characters, yield parameters, tuber yield and quality consistently and
significantly. Highest tuber yield (298.9 q ha-1), net returns (Rs. 225321) and net returns
per rupee invested (3.06) were obtained with the application of 125% NPK. Quality
parameters like starch content and graded yield of large sized tubers were found higher
with black polyethylene mulch than no mulch. Present study also revealed that for higher
tuber production potato crop should be planted on ridges with black polyethylene mulch
and 100% NPK or transparent polyethylene mulch with 125% of the recommended NPK.
