Yield and quality of traditional scented rice varieties in organic cultivation under foothills of Shivalik Himalaya, India

Abstract

To study the performance of traditional scented rice varieties under organic cultivation, a field experiment was conducted at G.B. Pant University of Agriculture and Technology, Pantnagar, Uttarakhand during kharif 2020 to evaluate 10 traditional scented rice varieties namely Kubri Mamhani, Kudrat-5, Chinar-20, Kesho Pohu, DRK, Kudrat-5, Pusa-1121, Type-3, Taraori and Tilak Chandan. The results revealed that the Kudrat- 5 achieved the highest grain yield (42.46 q/ha) and Chinar-20 with the highest harvest index(48%). Regarding quality parameters, higher hulling percentage was recorded in variety Kubri Mamhani (84.4%) and Tilak Chandan (84.4%), milling percentage in DRK (98.5%) and head rice recovery (79%) in Kudrat-1. The varieties namely Type-3 and Taraori were susceptible for lodging while all other varieties were tolerant.Higher corticated grain length was observed in Pusa-1121 (10.93 mm) and width in Tilak Chandan (3.01mm). Similarly, maximum decorticated grain length was recorded inPusa-1121 (8.5mm) and width in Kesho Pohu (2.03mm), respectively.
