Optimization of Rice Plant Production (Oryza Sativa L.) in Swamp Land through Integrated Plant Management
Abstract
Swampland is a suboptimal land which is an alternative to the expansion of rice planting areas due to reduced irrigation paddy fields. Among the obstacles to increasing rice production in swamps are cultivation techniques that still use local seeds and traditional planting methods. The purpose of this study is to improve the technique of rice cultivation in swamps by integrating the use of superior varieties and planting methods to increase production. Field experiments are arranged based on Spit-plot design. As the main plot is the planting method (C), namely C1 = conventional planting method, C2 = the seeding method (spread direct seedlings) without planting spacing, C3 = Planting Method Jajar legowo 4: 1; For subplots, there are varieties (V), namely V1 = Ciherang, V2 = Inpari-30, V3 = Mikongga; thus there were 9 treatments. Each treatment was repeated three times so that there were 27 experimental plots. The parameters observed were plant height (cm), the total number of tillers per clump, number of productive tillers, number of grain per clump, percentage of empty grain (%), the weight of 1000 grains (g), grain weight per clump (g), and grain weight per 2 x 2 m (g) trial plot. The resulting data were analyzed using Analysis of Variance, if the treatment showed a real effect, then proceed with the BNJ test. The results showed that: (1) planting method Jajar legowo 4: 1 can increase yield by 28% compared to spread direct seedlings, and 11.59% compared to conventional planting methods. (2) Inpari 30 varieties in swampland fields can produce better than Ciherang and Mikongga varieties, which reach an average of 8.54 tons/ha. (3) The potential of Inpari 30 variety of rice production in a swampland by planting Jajar Legowo 4: 1 is 9.16 tons/ha.
