Genotype X Tillage Interactions of Basmati and non-Basmati Indica rices (Oryza sativa L.) and Impact of Genotypic Expression on Biological Weed Control under Aerobic Planting Patterns

Twenty four genotypes of Basmati and non-Basmati rice (Oryza sativa) were evaluated under transplanted aerobic planting patterns, zero-till unpuddled flats and permanent raised beds in a core experiment of Collaborative Participatory Rice-Wheat Consortium for the Indo-Gangetic Plains. The soil microbes made soil ready and maintained for the next crop by bio-burning and Bio-tilling. The varieties Pusa Basmati-1, Basmati 370, Type-3, N-10B, Vallabh Dhan-1 and Vallabh Basmati-8 are tall growing and had more foliage whereas Sugandha-2, Sugandha-3, CT-6510-24-1-R, IR-64, IR-55-423, and Magadh have early growth vigour; hence all these suppressed the weeds efficiently. The varieties Type-3, N10 B, Pusa Basmati-1, CT-6510-24-1-R and Anjali varieties gave higher yield when transplanted on raised beds and suppressed the weed growth significantly and thus reduced cost of cultivation.
