Abstract

Susilawati S, Irmawati I, Sukarmi S, Kurnianingsih A, Mutia A. 2019. The application of biochar and water table at one month after planting on growth and yield of shallot. Jurnal Lahan Suboptimal: Journal of Suboptimal Lands. 8(2):202-212. The success of onion self-sufficiency is the arrangement and growth of production centers that are not only concentrated in Java. The research aimed to evaluate the effect of biochar application and water table treatment on growth and yield of shallot plant. The research was conducted in Experimental Farm of Agriculture Faculty, Sriwijaya University at 2019. Materials used consisted of shallot bulb of Bima Brebes variety, oil palm shells biochar, paper bag, and plastic bag. While the tools used were hoe, gauge, pH meter, basin, scale, and oven. Factorial Randomized Block Design was used with two factors and three replicates. The first factor was biochar dosages consisting of P1 (51 g/plant) and P2 (102 g/plant) and the second factor was soil water table consisting of T0 (no water table treatment), T1 (10 cm of water table below soil surface), T2 (15 cm of water table below soil surface) and T3 (30 cm of water table below soil surface). The observed parameters included plant height, leaf number, tiller number, total bulb fresh weight, bulb fresh weight, bulb dry weight and root length. Results showed that the application of biochar and water table treatment statistically affected the growth and yield of shallot plant. The effect on both growth and yield parameters were obtained from the combination of P2T3. Correlation was found between plant height and leaf number, total bulb fresh weight and bulb fresh weight.

Abstract

Surahman H, Sulaksono G, Sembiring Z, Kurnianingsih A, Priadi DP, Asmono D. 2020. Effect of plant gowth regulator on the gowth of zygotic embryos in three types of oil palm fruit (Elaeis guineensis Jacq.) in tissue culture. Jurnal Lahan Suboptimal : Journal of Suboptimal Lands 9(2): 149-159.Embryo culture is a widely used and effective way of overcoming the dormancy nature of seeds in oil palm.  At the germination stage, the influence of gowth regulators play an important role although in relatively lower concentrations in the germination media. This aim research determined the effect of adding various concentrations of gowth regulator on the three types of oil palm fruit based on the thickness of the shell. This research carried out at the Tissue Culture Laboratory of PT. Sampoerna Ago Tbk. from September 2018 to January 2019. The gowth regulator substances used in this study were NAA, BAP and GA3. The composition of the gowth regulators used were H1 = 0.05 mg/L NAA + 0.1 mg/L BAP + 0.1 mg/L GA3, H2 = 0.05 mg/L NAA + 0.3 mg/L BAP + 0.1 mg/L GA3, H3 = 0.05 mg/L NAA + 0.5 mg/L BAP + 0.1 mg/L GA3 and H4 = No gowth regulator. While the types of oil palm fruit used were C1 = Dura, C2 = Tenera and C3 = Pisifera. This research used a factorial complete randomized design with three replications. The results showed that in general the use of gowth regulator substances H1 = 0.05 mg/L NAA + 0.1 mg/L BAP + 0.1 mg/L GA3 and the type of dura fruit showed positive results based on viability, scoring, survival and height of plantlets when compared with other treatments.
