Abstract

The purpose of this experiment was to investigate the effect of various levels of seed maturity and conservation methods on seed vigor and seedling vigor of broad bean( Phaseolus vulgaris L.). The experiment was conducted at Darmaga IV Experimental Station, seed Science and Technology Laboratory - Leuwikopo IPB and BIOTROP, Tajur. Broad bean no. 1058 was used in this experiment. Seed vigor testing was carried out in the laboratory, using Completely Randomized Design, while Randomized Complete Block Design was applied to field experiment for testing seedling vigor. The treatment consisted of two factors as followed:(I) Levels of seed maturity: MI = 27 daf (days after flowering), M2 = 30 daf, M3 = 33 daf, M4 = 36 daf, and M5 = 39 daf (2) Conservation methods: K 1 = pods were spread out in the processing unit room for about 1 week, the seed moisture content was dropped to 40%; K2 = sun drying; K3 = artificial drying, using seed dryer 400C. Seed moisture content was dropped to 9 - 10% in K2 and K3 methods. Broad bean seeds harvested at 36 daf, the time when physiological maturity was reached, followed by either sun drying or artificial drying, showed a maximum seed vigor. However, a higher seedling vigor resulted from sun drying as compared to artificial drying. Before physiological maturity seed vigor and seedling vigor was still lower, while the vigor was reduced after physiological maturity.

Abstract

Oil palm is one of Indonesia’s major plantation commodities and plays an important role as a source of national foreign exchange. The decline in oil palm productivity due to the high proportion of damaged and unproductive plants has increased the need for replanting supported by the production of high-quality seedlings. The success of seedling production is influenced by growing media and fertilization, particularly in Ultisol soils, which are characterized by low organic matter content. This study aimed to evaluate the growth response of oil palm seedlings to the application of rice straw compost and NPKMg fertilizer and to determine the best treatment combination in the main nursery. The experiment was conducted for three months using a Completely Randomized Design (CRD) with five treatments: p0 = 100% of the recommended dose of NPKMg p1 = 200 g rice straw compost + 50% of the recommended dose of NPKMg; p2 = 250 g rice straw compost + 50% of the recommended dose of NPKMg; p3 = 300 g rice straw compost + 50% of the recommended dose of NPKMg; and p4 = 350 g rice straw compost + 50% of the recommended dose of NPKMg, with four replications. Data were analyzed using analysis of variance (ANOVA), followed by the Least Significant Difference (LSD) test at the 5% significance level. The results showed that the combination of rice straw compost and NPKMg fertilizer improved seedling height and shoot dry weight, whereas leaf number, stem diameter, root dry weight, shoot-to-root ratio, and seedling quality index did not improve. The application of 250 g rice straw compost combined with 50% of the recommended dose of NPKMg (15-15-6-4) was the best treatment and produced seedling growth comparable to that obtained with the 100% recommended dose of NPKMg. Therefore, this combination is recommended as an alternative to reduce the use of inorganic fertilizer by up to 50%.

Abstract

Opencast mining caused heavy deforestation and barren land in Jambi. This ex-mining land must be reclaimed by planting crops based on biofertilizers containing mycorrhizae, this is a potential alternative that provides benefit both agronomy plant and ecosystem specially replanting with oil palm. Those are the technology for reclamation ex-coal mining soil. This research aim is to examine the effect of four combinations indigenous isolate of Arbuscular Mycorrhizae Fungi (AMF), which is originated from ex-coal mining soil that combined with Phosphorous fertilizers to minimize utilizing P fertilizer at oil palm pre-nursery, to improve soil fertility, and seedling growth. Hence, this research was arranged in factorial experiment with 2 factors, using a complete randomized design with three replications. The first factor is five different mycorrhizae isolates, representing a broad range of endomycorrhizae fungi, there are: without indigenous AMF, isolate of Glomus sp. 3, isolates of Glomus sp. 6, isolates of Glomus sp. 15 and isolates of Glomus sp. 16. The second factor is P fertilizer: control (without P fertilizers), fertilizer dosage P 25%, 50%, 75%, and 100%. Variables measured are shoot height, number of leaves per plant, total leaf area per plant, and plant stem diameter. The data were analyzed by analysis of variance to see whether there was an interaction between the MVA isolate and the P fertilizer dosage. The result showed a significant effect on palm oil seedling growth, shoot height, number of leaves per plant, total leaf area per plant but there is no interaction on the stem diameter. Plants that are inoculated with mycorrhizae have greater P content in leaves than those not inoculated. The types of isolated Glomus sp.3 and dosage P 75% of recommended dosage, give the best seedling growth. This research concluded that inoculation with AMF could minimize P fertilizers doses.
