The current study was formulated to analyse the impact of different biodegradable and synthetic mulches on growth and yield parameters of mulberry plant. Among the selected parameters survival rate of mulberry plants was recorded to be maximum in T-2 i.e, paddy straw and husk as 95% followed by T-1 and T-3 i.e, Black polythene mulch and Green branches of tree respectively as 90% and least for Control i.e, without any mulch as 70%. Least population of weeds with minimum intensity was recorded in T-1 (05) followed by T-2 (08) and T-3 (10). Maximum weed flora with highest intensity of weeds was found in Control i.e, without any mulch (20). For the studied samples, maximum soil moisture percentage and moisture retention capacity (MRC) of 66.57 & 95.6% was recorded in T-1 followed by T-3 as 40.31 & 87% and T-2 as 16.36 & 91% and minimum in control as 13.43 & 85.56%. The pH was recorded as 6.1 in T-1 depicting the slightly acidic soiland could be viewed as the most appropriate soil pH for mulberry cultivation. Available NPK were recorded to be in the most ideal range for T-1 as 8.2, 1.3 and 9.6%. Maximum leaf size was recorded in T-1 as 126cm followed by T-2 and T-3 as 116cm and 110cm respectively and 105cm in control. Moisture percentage was recorded to be highest 76.23% followed by 74.61% and 54.16% for T-3, T-1 and T-2 respectively and 68.2% in control. Maximum MRC was observed in case of plants grown under Black polythene mulch (73.24%) and least in green branch mulch (61.39%). Therefore, it can be concluded that application of suitable bio-mulches in mulberry fields can reduce the dependency of chemical weedicides.
