Title : Yield and quality of aromatic rice (Oryza sativa L) as influenced by organic nutrient management in rainfed condition of Assam

Abstract :

A field experiment was conducted at Instructional-cum-Research Farm of Assam Agricultural University, Jorhat, Assam, India during kharif season of 2018 and 2019 to study the effects of organic nutrient management on growth, yield attributes, yield and quality of aromatic rice varieties. The variation in the growth, yield attributes and yield among the aromatic rice varieties was found significant and the highest grain yield was recorded in Keteki joha which was found to be statistically at par with Chakhao poireiton. Among the organic nutrient management treatments, application of vermicompost @ 30 kg N/ha+ in situ green manuring with Sesbania aculeate+seedling root dip treatment with Azospirillium and phosphorus solubilizing bacteria (PSB) @ 3.5 kg /ha each (N3) produced the highest number of panicles /m2, longest and heaviest panicle and the highest grain and straw yield during both the years. The quality profile in terms of crude protein content and content of Fe, Zn, Mn were influenced by the organic nutrient management and found highest with the N3 treatment. The aromatic rice varieties showed significant variations in their quality parameters. The cultivar Kola joha was found superior in respect of Fe, Zn and Mn content whereas Keteki joha was found superior in respect of crude protein, Ca and Mg content, head rice recovery percentage and length and breadth ratio over others. The lowest amylose content (6.23%) was recorded in case of Chakhao poireiton.
