Abstract: An experiment was conducted during rabi season at the research farm of Agronomy, College of Agriculture, Central Agricultural University, Imphal, 2011-2013. The results of the experiment revealed that T6 (10 t ha-1 of rice husk) produced the maximum plant height, number of leaves, number of stem hill-1, maximum fresh and dry weights of aerial portion hill-1. Significantly highest soil moisture content was found in T7 (11 t ha-1 of rice husk) compared to other treatments. The weight of tubers hill-1 (288.60 g hill-1) and yield per hectare (95.77 q ha-1) was significantly recorded highest with T6 (10 t ha-1 with rice husk) treatments. Yields were statistically same by using mulch @ 7, 8, 9 and 11 t ha-1. Almost all the parameter recorded, T1 (control) treatment reveals lowest values compared to others. Harvest index showed some variation among the treatments but not up to the level of significant. T5 (9 t ha-1 with rice husk) gave the maximum value of harvest index. The highest net return of Rs.292138 ha-1 was obtained by growing potato mulching with 10 t ha-1 of rice husk (T6) which was followed by the mulching with 9 t ha-1 of rice husk (T5) of Rs.245380 ha-1 with a benefit: cost ratio of 4.2 and 3.7, respectively.
