Abstract

The aim of this research is to determine  the response of various tidal swamp varieties of paddy rice (Oryza sativa L.) on various ground water levels. The experiment was conducted in an experimental field of Faculty of Agriculture, Riau University, from July until December 2016. The experiment was conducted by experiment using completely randomized design (RAL) with two factors, namely rice field varieties, and water table height. Varieties are used: IR-42, Inpari 13 and Bamban Lentik. Height of ground water used 5 cm, 10 centimeter, 15 cm and 20 centimeter. The observed parameters were: plant height, tillers maximum number, number of productive tillers, age of panicles, panicle length, harvest age, percentage of unripe rice per hill, weight of dried grain per clump, and weight of 1000 grain of pithy rice. The results obtained in the analysis using anova and HSD of 5%. The results showed that the responses of IR-42 and Inpari 13 varieties to the 10 cm height of the ground water surface resulted in the age of panicles and the fastest harvest age, and yielded the weight of dry grain per clump, the percentage of unlogged rice per hill and the weight of 1000 rice grains. Response of Bamban Lentik varieties to 20 cm high water levels showed the age of panicles and the fastest harvest age, and yielded the weight of dry grain per hill per hill, the percentage of pithy rice per hill and weight of 1000 grain of the highest pine rice.Keywords: Water level, varieties, rice

Abstract

This study aims to describe the profile of P3A group members that influence production unit in supporting the success of rice farming of tidal land in Indragiri Hilir District. Research has been conducted in Indragiri Hilir District in Kempas, Reteh and Keritang District started from September 2016 until February 2017, using survey method with descriptive analysis of regression and correlation. The results of this study indicate that members of P3A tidal land rice paddy in Indragiri Hilir, the majority members of P3A are senior high school educated, male, productive age, have small family members, had narrow land area, the majority work on private land and 68,67% of P3A farmers rice productivity in Indragiri Hilir District rice increase and highly increase. The any change in attitude of P3A paddy farmers in Indragiri Hilir District has an effect on rice productivity increase of 0,313 ton.ha-1 and has a pretty positive relationship to the variable self efficacy, motivation, interaction member, cohesion member and norms members in supporting the success of paddy rice farming tidal land. Self efficacy factors, work motivation, member among interaction, member cohesion, member norms and norms of P3A members in Indragiri Hilir Regency have a relationship with each other with strong correlation value. Keywords: Member profile, P3A, paddy rice farming, productivity

Abstract

This research was aimed to determine the effect of interaction between goat’s urine and bokashi fertilizer, and to get the decent dosagein the growth of cocoa seeds. This research was conducted at the experimental station of Agriculture Faculty of Riau University, from september 2016 to january 2017, factorial by using completely randomized design (CRD) method, 3 replicarions, which consist of two factors. The first factor, goat’s urine dosage consisted of 3 levels (0, 50, and 100 ml/polybag) and the second factor, bokashi fertilizer dosage, consisted 3 levels (0, 50 and 100 g/polybag).The parameters observed were seedling height, leaf number, stem diameter, root volume, leaf area, plants dry weight, and  the shoot to root ratio. Observationts of each parameter were analyzed statistically using analysis of variance and Duncan's new multiple range test (DNMRT) level of 5%. The results show that the interactionbetween goat’s urine and bokashi fertilizer has no significant effect on all parameters, and the goat’s urine dosage of (50-100) ml/polybag and bokashi fertilizer dosage of(50-100) g/polybag is thedecent dosage to increase the all parameters. Keywords: goat’s urine, bokashi fertilizer, cocoa.
