Abstract

The experiment has been taken up at Turmeric research station, Kammarpally for the four consecutive years from 2019-20 to 2022-23 to assess the effect of different plastic mulches on growth and yield of turmeric under different plastic mulch conditions. Turmeric crop is severely invaded with weeds during initial stages. Prolonged weed free period is needed for good crop stand and better plant growth. Labour availability during critical weed control stages of crop trigger the pressure on weed management and turmeric crop also sensitive to soil moisture throughout its crop period. Plastic mulching is one of the best alternates to control the weeds and improve the water use efficiency. In this trial, different plastic mulches black plastic mulch 25 microns and 30 microns, gray plastic mulch with 25 microns and 30 microns have been taken as plastic mulching material and without any plastic mulching was taken as control. The experimentation was done in a randomized block design and replicated four times. The results enunciated that the plants with black plastic mulch with 30 microns thickness recorded maximum mean fresh rhizome yield (42.99 t/ha) followed by black plastic mulch with 25 microns thickness (37.03 t/ha) as compared to other mulches and control (Without mulching).

Keywords

Turmeric, mulching, fresh rhizome yield, plant height, black plastic mulch

Conclusion

In accordance with the results attained under present study and possible reasons for the higher growth and yield having discussed, it can be concluded that higher growth characters and higher turmeric fresh rhizome yield was obtained under mulching of turmeric crop with black plastic mulch of 30 microns followed by black mulching of 25 microns. It also suppresses with weed growth and control the soil run off due to the heavy rains to greater extent.
