Abstract:
A field experiment was conducted during kharif season (2016-2017) on Tulsi (Ocimum gratissimum) crop for screening of resistance in natural field condition against leaf spot disease caused by Alternaria alternata at Main Experimental Station, Department of Medicinal and Aromatic Plants, ANDUAT, Kumarganj, Ayodhya. The observed parameters of oil content percent, number of leaves per plant, leaf weight per plant (kg), leaf yield (q/ha) and disease severity percent were recorded in 90 days old plants. The results obtained revealed that germplasm NOB-7 showed maximum oil content (2.14%) while the maximum leaves yield recorded in NOB-1 (14.81 q/ha) with disease severity (15%).
