Rio – de-Janeiro. The experiment was laid out in strip plot design with five replications. High density polyethylene shade materials were used for providing shade at required levels. The shade treatments were open (S0), 25 (S1), 50 (S2) and 75 (S3) per cent and mulch treatments were 25 (M1), 50 (M2), 75 (M3) and 100 (M4) per cent of the recommended dose.
The effect of shade on enhancing sprouting was found to be significant mainly during the early stages. The effect of mulch was also found to be significantly and increasing levels of mulch increased sprouting.
The effect of shade and mulch on growth parameters: leaf number, leaf area, plant height, tiller number, chlorophyll content, DMP, NAR, CGR, BR, UI, HI and top yield under low shade (25%) exhibited significant superiority with respect to growth and yield contributing factors. Most of the parameters from open were inferior to shaded conditions. In general, mulching retained more moisture, reduced soil temperature and produced positive changes in growth and yield contributing factors.
Maximum green ginger and dry ginger yield were resulted from low shade (25 %) followed by medium (50 %) and heavy shade (75 %). The trend in green and dry ginger yield obtained from open condition was significantly inferior to all shade regimes. The effect of mulch on green ginger yield was also found to be significant. Under low shade (25 %) M3 and M4 were on par. Under medium and heavy shade M3 and M4 were comparable.
In general the quality of the produce was found to be superior under shaded conditions. The uptake of N showed an increasing trend with increasing shade intensities but P and K showed an increasing trend upto 50 per cent and then a decrease. A general increasing trend in NPK uptake was also observed with increasing mulch levels.
The study suggests that ginger is a shade loving plant giving maximum yield under low shade followed by medium and heavy. Under open condition, mulching gave a progressively increasing trend in yield, and therefore the existing recommendation (30 t ha-1) is necessary. But under low shade 25 per cent of the mulch requirement can be reduced without affecting the final yield.
