Abstract

ABSTRACT Red chili has a potential to be developed in sub-optimal land (Inceptisol, Ultisol, and peatland) by adding lime as amelioration. Besides that good characteristics of peat soils can also improve Ultisol and Inceptisol soils when is mixed. With the application of these technologies can increase the productivity of red chili. This study aimed to examine the effect of agricultural lime on several growing media and to determine the best treatment on the growth and yield of red chili. The study was conducted at the experimental farm of the Faculty of Agriculture, University of Riau from April to September 2018. The research was carried out in factorial with 2 factors and designed by completey randomized design and then tested with Duncan's new multiple range test. The first factor was media Ultisol, Inceptisol, peat, peat+Ultisol, and peat+Inceptisol. The second factor consisted of lime 0,0 x Al-dd, 1,0 x Al-dd and 2,0 x Al-dd. The observed parameters were stem diameter, flowerage, number, length, diameter, and weight. The results showed that lime application 1,0 x Al-dd for Inceptisol provided a good effect on stem diameter, flowerage, number, length, diameter, and fruit weight. The best treatment was found in 1,0 x Al-dd on peat+Inceptisol with a productivity of 135,10 per plant. Keywords: Lime, Planting media, Chili, Ultisol, Inceptisol, Peat,

Abstract

The purpose of this study is to determine the effect of the interaction of sago pulp compost and phosphorus fertilizer, the single factor of sago pulp compost and phosphorus fertilizer, and to obtain the optimal dosage of sago pulp compost and phosphorus fertilizer for growth and production of okra plants. The study was conducted at the Experimental farm of the Faculty of Agriculture, University of Riau. The study used a factorial randomized block design (RCBD). The first factor is the dosage of sago pulp compost (K) K0 : 0 kg per plot (0 tons.ha-1), K1 : 1,75 kg per plot (8,75 tons.ha-1), K2 : 3,50 kg per plot (17,50 tons.ha-1) and K3 : 5,25 kg per plot (26,25 tons.ha-1). The second factor is the dosage of SP-36 phosphorus fertilizer (P) P0 : 0 g SP-36 per plot (0 kg.ha-1), P1 : 10 g SP-36 per plot (50 kg.ha-1) and P2 : 20 g SP-36 per plot (100 kg.ha-1). The parameters observed were plant height, number of fruits per plant, fruit length, fruit diameter, fruit weight per plant, number of fruits per plot, and fruit weight per plot. The data obtained were statistically analyzed using variance and continued with Duncan's New Multiple Range Test at the level 5%. The results showed that the interaction of sago pulp compost and phosphorus fertilizer could increase plant height, fruit length, fruit diameter, fruit weight per plant, number of fruits per plot, and fruit weight per plot. The best dosage of the growth and production of okra plants is 5,25 kg of sago pulp compost per plot and 20 g SP-36 of phosphorus fertilizer per plot, but the replicated 5,25 kg of sago pulp compost per plot and 10 g SP-36 of phosphorus fertilizer per plot was the optimal dosage that able to produce okra as much 7,01 tons.ha-1.

Abstract

Soybean production in Indonesia has decreased year by year. This is caused by high rainfall potentially causing water-saturated land. This is due to heavy rain which can cause the water to become saturated. Implementation of drainage and groundwater depth control is expected to increase soybean productivity. The purpose of this study is to determine the best groundwater depth for growth, production and physiological quality of soybeans produced. The study was conducted at the Experimental farm of the Faculty of Agriculture, the University of Riau from February to May 2019. The depth of the groundwater used was 5 cm, 10 cm, 15 cm, 20 cm, and control treatment. The parameters observed were plant height and number of nodes, flowering age, age of harvest, number of seeds per plant, dry weight of seeds per plant, the weight of 100 seeds per plant, the suitable percentage for seed, standard germination test, and index value test. Data were analyzed by analysis of variance then continued with Duncan's New Multiple Range Test at the 5% level. The results showed that a depth of 5 cm, which produces poor aeration, leads to unoptimal absorption of nutrients, thus plant height and number of nodes, number of seeds per plant, dry seed weight per plant, 100 seed weight per and the suitable percentage for seed decreased. In the treatment, a water level of 20 cm from the soil gave the best results in terms of seed growth, production and physiological quality due to good ventilation, sufficient water availability and optimal absorption of nutrients.
