Abstract
The experiment was planned and executed at Plasticulture farm of CTAE Udaipur
(Rajasthan) during June, 2017 to Sep, 2017. This study included objectives, to study
about the impacts of mulch on microclimate of the soil, tostudy the effect of mulch
and drip (Supplemental) irrigation on growth and yield parameter of black gram
(Vigna Mungo L.), to evaluate the economic feasibility of mulch and drip
(Supplemental) irrigation on kharif black gram. The experiment was laid out in
randomized block design with nine main treatments No irrigation with Polypropylene
Woven Mulch (PPWM) (T1), Black Plastic Mulch (BPM) (T2), No Mulch (NM) (T3),
One irrigation first at 10 days dry spell with PPWM (T4), BPM (T5), NM (T6) and
Two irrigation first at 10 days and second at 10 days dry spell with PPWM (T7), BPM
(T8), NM (T9) with three replications. The minimum depletion of soil moisture was
observed in PPWM and BPM compare to NM. The highest soil temperature observed
under BPM and PPWM mulch which was 2.2°C to 3.5°C and 1.3°C to 2.3°C more
than the NM. Significant effect of plastic mulch and supplemental irrigation on plant
height, number of leaves per plant, number of branches per plant, pods per plant
,seeds yield per plant, yield per plot and yield per ha was observed at all growth stages
where one and two irrigation with PPWM and BPM gave superior performance over
NM and no irrigation treatments.The highest net income of ₹. 41,946 (T7) and ₹.
40,846 (T4) per hectare with O: I ratio of 1.94 and 1.91 was recorded in PPWM.The
lowest net income of ₹. 4708 per hectare was recorded in BPM and no irrigation (T2).
PPWM and BPM found better net income than NM, however, O: I ratio in
supplemental one and two irrigation PPW and BPM mulch was found higher than in
NM and no irrigation treatments.
