Abstract

Mulching is essential for sustainable horticulture practices in this region as it helps reduce soil moisture loss,
regulate soil temperature and minimize erosion. Examining different types of mulch in this specific climate can aid in
developing adaptive strategies to mitigate the adverse effects of climate variability and enhance horticultural resilience. In
the experiment, two factors were considered: five types of mulching materials—maize straw, polythene (25 microns), woven
mulch, and silver mulch—and two fertilizer levels—75 % and 100 % of the RDF (120:100:100 NPK kg/ha). The experiment
was conducted under the All India Coordinated Research Project on Potato at JNKVV, Chhindwara. Results revealed that all
mulched treatments significantly outperformed the control (without mulch). The highest yield was recorded with polythene
sheet mulch (31.73 t/ha), followed by maize straw mulch (30.13 t/ha). Maize straw mulch provided an additional yield of
10.24 t/ha over the control. Among fertilizer levels, 100% RDF (120:100:100 kg/ha NPK) produced the highest yield (31.73
t/ha). The combined effect of mulch and fertilizer showed that the highest yield (30.93 t/ha) was obtained in the F2M2
treatment (100% RDF with polythene mulch), whereas the lowest yield (18.73 t/ha) was recorded in the F1M0 treatment
(75% RDF without mulch). These results highlight the importance of mulching and optimized fertilization in enhancing
potato yield in the central plains of India.
