Plant Distance Effect on Rice Cultivation System of Rice Intensification (SRI) Method on Tillers and Yield Numbers in East Sumba Regency

Abstract

SRI is known as a set of methods to increase the productivity of paddy fields by changing the management of yields, soil, and fertilizers/nutrients. The main components of using the SRI method include: transferring young seedlings, planting one seed per hole, wide spacing, keeping the soil moist and not stagnant, controlling weeds by manual weeding, and adding soil organic matter. The study aims to determine the number of SRI rice tillers based on different spacing treatments and their effect on yield productivity. The results of the two treatments of plant spacing, namely 30 x 30 cm (A) and 20 x 10 cm (B) based on statistical tests using the T-Test, showed no significant difference between the two treatments on the number of tillers produced. While the yield showed that treatment A produced 4.27 tons/ha and treatment B was 4.7 tons/ha, so it concludes that spacing (A) had higher crops than spacing (B).
