Application of New Superior Varieties of Irrigated Land Rice within Integrated Crop Management

Abstract

Rice is an important food crop commodity and a priority of the agriculture program in Riau Province. In Siak Regency, the total production of irrigated land rice in 2018 was 21,937.02 t Milled Dry Grain (MDG) with average productivity of 5.47 tons/ha of Harvested Dry Grain (HDG). In general, the productivity of irrigated land rice in Siak Regency is quite high, with varies between locations (4.68-6.60 tons/ha HDG). The purpose of this study was to determine the production of Logawa, Ciherang and Inpari 42 varieties on the application of ICM for irrigated land rice in Siak Regency, Riau Province According to the results of research on irrigated land rice production of new superior varieties (Logawa, Ciherang and Inpari 42) in integrated crop management (ICM) obtained an average production of 8.50 tons/ha HDG. Low productivity of rice is caused by (i) the use of inferior quality varieties, (ii) the use of fertilisers that are not following the recommendations, and (iii) the location-specific technology has not been applied yet. Increasing rice production and productivity can be carried out by using new superior varieties within ICM. The results showed that the application of new superior varieties within ICM resulted in higher HDG production (8.25 - 8.90 tons/ha) compared to non-ICM (6.20 - 6.50 tons/ha). The increase of HDG production are ranging from 2.05 - 2.40 tons/ha (33 - 37%) compared to non-ICM. The application of new superior varieties within ICM increasing profit of Rp 21,963,750 - 24,609,000 (30 - 33%) each planting season/ha. The total costs incurred by ICM farmers for one planting season are Rp. 15,161,250 - Rp. 15,441,000/ha with an income of Rp. 37,125,000 - Rp. 40,050,000/ha/season and RCR value of 2.45-2.59 and BCR of 1, 23 - 2.59.
