Abstract:
The system of rice intensification (SRI) became very popular in terms of higher production, but it was also noticed that implementation of all the components of SRI is very difficult for the farmers. To investigate the most appropriate component of SRI the field experiment was conducted at research farm of Bihar Agricultural University, Sabour, Bhagalpur, India during Kharif 2019. The experiment was laid out in completely randomized block design with eight treatments replicated thrice. The first treatment was conventional puddled transplanted rice (CPTR), thereafter six treatments were also CPTR with an addition component of SRI in each treatment and the last treatment was sole SRI. Results revealed that all growth parameters i.e., plant height, leaf area index and dry matter accumulation obtained highest in the SRI at all growth stages. The highest grain yield (6020 kg ha-1) was recorded in the SRI, which was statistically at par with CPTR with 12 days seedling (5693 kg ha-1). The highest straw yield (6693 kg ha-1) was recorded in the SRI, which was statistically at par with CPTR with 12 days seedling (6473 kg ha-1), CPTR with 1 seedling/hill (6447 kg ha-1), conventional PTR (6170 kg ha-1), CPTR with spacing of 25cm × 25cm (5943kg ha-1) and CPTR with N-Organic: inorganic (5873 kg ha-1). Based on these findings the 12 days old seedling and single seedling/hill were found most effective among the SRI components in conventional puddled transplanted rice.
