Abstract

Jambi Province has large peatlands (621,089 ha). Utilization of that land in agricultural sector will contribute in economic development of surrounding society. Tangkit and Paun Pineapple are plant genetic resource (PGR) that must be maintained and secured from extinction and erosion of genetic potential. This is because the real PGR continues to be utilized for the survival and welfare of the community. The research purpose was to know the morphological of PGR pineapple that have potential to grow, produce and adapt in peatland of Jambi Province. Survey method was used in this research and conducted in Tangkit Baru Village, Sungai Gelam District, Muaro Jambi Regency and Sungai Baung Village, Pengabuan District of Tanjung Jabung Barat Regency, Jambi Province in 2016 and 2017. The results showed that significant different were occurred between Tangkit and Paun pineapple in leaf morphology, flowers, fruit, harvesting age and production/ha. Production of Tangkit and Paun pineapple were 13.5 ton/ha and 9.1 - 13 ton/ha respectively. The leaves of Tangkit pineapple were prickly, meanwhile, Paun pineapple was not thorny; Fruit of Tangkit pineapple was round oval, and Paun pineapple cones-like with 3-4 times bigger in size than Tangkit pineapple (3.5 - 5 kg). Paun Pineapple can only grow in peatland with 3 m depth while on shallow peat fruit production is not optimal. Tangkit Pineapple grow and produce well on peatland with pH ≤ 5.0. Paun Pineapple also well adapted to low peatlands with elevation 0 - 30 m asl and soil pH 4.5 - 6.5.

Abstract

This research was carried out on the Experimental Garden, Faculty of Agriculture, Abulyatama University, Aceh Besar. This research was conducted from September 26th to December 2nd, 2017. This research was assigned in a Completely Randomized Design (CRD) factorial with 3 replications. There were 12 combinations of treatments and 36 units of experiments. The first factor was Trichoderma viride Fertilizer (T) which consists of 4 levels: T0 = 0 gram/polybag, T1=50 g/polybag, T2=100 g/polybag, T3=150 g/polybag. The second factor was BASF NPK Fertilizers (N) consists of 3 levels: N = 0 g/polybag, N1=3 g/polybag, N2=6 g/polybag. The parameters observed in this study were plant height, bulb diameter, wet weight and dry weight of bulbs. The results revealed that various doses of T. viride fertilizer increased the plant height respectively at 20 and 40 days after planting. Surprisingly, there was no significant difference in plant height at 60 days after planting. The best results for the application of T. viride fertilizer were found in T1 (50 g/polybag). This fertilizer also exhibited insignificant results in bulb diameter, wet weight and dry weight of bulbs at all observed ages. The application of BASF NPK fertilizers did not significantly affect all observed parameters (plant height, bulb diameter, wet weight and dry weight of onion bulbs). There were no interactions due to application of T. viride fertilizer and BASF NPK fertilizers to all observed parameters.

Abstract

The ability to develop resistance has been demonstrated by Rhizobacteria in several plant species in order to providing protection against plant pathogen attacks. The use of Rhizobacteria is expected to suppress the attack of Fusarium pathogen in local pepper plants in Aceh. This study is aimed at obtaining information about the important role of Rhizobacterium in inducing the resistance of local pepper plants in Aceh to the attack of Fusarium oxysporum. The research was conducted from March to September 2018 at Seed Science Laboratory and Experimental Garden of the Faculty of Agriculture, Syiah Kuala University. The study used Completely Randomized Design (CRD) Factorial with 2 factors. The first factor was the local peppers (Odeng, Lamando Lapaben, Super Lamando 002 and Lanyoe SS). The second factor was Rhizobacteria isolates (HWI 5 (4) and HWI 8 (6)) which were obtained from the collection of Seed Science Laboratory. The parameters observed: pathogen incubation period, plant height, stem diameter and number of productive branches. The results revealed that the incubation period of F. oxysporum varied in each genotype and type of Rhizobacteria. The application of Rhizobacteria is slowing down the incubation period to 1-3 days in all tested genotypes. Rhizobacteria increased the plants growth especially in HWI 8 (6), characterized by taller plants and larger trunks. The highest interaction between the local genotype of pepper plants and the type of Rhizobacteria was found in the genotypes of Lamando Lapaben and HWI 5 (4) for its number of productive branches.

Abstract

Flooding is a natural phenomenon that often occurs in the rainy season arrives with high rainfall. This phenomenon give an effect to plant growth if it occurs in agricultural areas. This research was carried out at Samarinda, Indonesia. This study uses a completely randomized design non factorial, consists of 4 lavels ie; 4 hours height level 50% flooding (J1), 8 hours height level 50% flooding (J2), 4 hours height level 100% flooding (J3), 8 hours height level 100% flooding (J4), carried out with 4 repetitions. Flooding simulation is carried out 5 times in each growth phases of tomato plants. The data analysis used Anova. If the variance is significantly different, then followed by the LSD (Least Significance Different) at 5%. The results showed that simulation of flooding with times 8 hours height level 50% flooding had a morederate negative effect on tomato plants. The flooding simulation with times 8 hours height level 100% flooding gives the highest negative effect on tomato plants and the root, due to excess water requirements so that plants cannot meet needs of the plants.
