Abstract

Wide space among oil palm Mature Stage I (MS  I) plantations has a potential to be planted with soybean by using intercropped system. One type of soil in oil palm plantations in Indonesia is Inceptisol which generally has low P availability. Efforts possible to increase P availability are the applications of inorganic P fertilizer and phosphate solubilizing bacteria (PSB). This study aims to learn the effects of various inorganic P fertilizer and PSB doses on the growth and yield of soybean in oil palm MS I plantation and determine the effects of intercropping soybean on the growth and physiology of oil palm MS I. The research was conducted at Ciparanje Experimental Field, Faculty of Agriculture, Universitas Padjadjaran, from February to May 2023. The study used randomized block design with seven treatments and four replications. Treatment consisted of different doses of Bacillus sp. and SP36 which included: 100% SP36, 50 kg/ha PSB + 25% SP36, 50 kg/ha PSB + 50% SP36, 50 kg/ha PSB + 75% SP36, 75 kg/ha PSB + 25% SP36, 75 kg/ha PSB + 50% SP36, and 75 kg/ha PSB + 75% SP36. Results showed PSB and P fertilizer had a significant effect on the dry weight of 100 seeds and leaf chlorophyll index of soybean. Dose of 50 kg/ha PSB + 50% SP36 increased the dry weight of 100 seeds by 3,99% and leaf chlorophyll index by 15,35%.

Abstract

Among problems encountered in the availability of quality seedlings in nurseries is a low percentage of seedlings ready to plant. The seedling will remain stunted if no treatment is provided. Therefore, there must be some treat-ments carry in the nursery, as increase seedling ready to plant. One of the problems causing lack of good seedling growth is less than optimal growth and the role of the root, thus, the increase in the growth of the tea plant seeds can be cultivated among others through im-proved root system. The objective of this re-search was to determine the effect arbuscular mycorrhizal fungi (AMF) and plant growth regulator (PGR) against the percentage of root seedlings were ready to plant. Root growth can be accelerated by the application of PGR roots, ability to function and role of the roots can be improved by application of biological fertilizers such as AMF. The experimental design used was a randomized block design combined con-centration of PGR roots consisting of Z0: 0 mg/mL; Z1: 25 mg/mL; Z2: 50 mg/mL; Z3: 75 mg/mL with a dose of FMA consisting of: F0: 0 g FMA/plant; F1: 5,0 g FMA/plant; F2: 7,5 g FMA/plant and F3: 10,0 g FMA/plant. The experiment was conducted at the Gambung Experimental Station at the Research Institute for Tea and Cinchona, Bandung, West Java, at a height of ± 1.350 m above sea level with the type of Andisols. Rainfall including B-type according to the classification of Schmidt and Fergusson (1951). The experiments resulted in the conclusion FMA 7,5 g dose combination treatment plants PGR-1 with a concentration of 25 mg/mL root, generating growth in both the percentage of root infection, seedling height, the number of leaves, and the amount of leaf chlorophyll and the percentage of tea planting material. The treatment resulted in a 35% increase in plant height, a number of leaves nearly 68% and the amount of chlorophyll is 83% higher compared to treatment without the FMA and without PGR. The percentage of 12 months old planting material with treatment reached 78,11% higher than the treatment without AMF and PGR which reached 49,28%.

Abstract

The intercropping system in oil palm plantations is an effort to optimize land, especially at the immature stages (IS), which have a large open space between the trees, so it can be used for cultivating annual crops such as maize. Oil palm trees are generally planted on marginal lands, such as Inceptisol, which generally lacks in phosphor (P). These problems can be reduced by applying arbuscular mycorrhizal fungi (AMF) to elevate P. This experiment was to determine the dosage and effectiveness of AMF that can improve the growth and yield of maize intercropped with a 4-year-old oil palm. The experiment was conducted at the Ciparanje Experimental Station, Faculty of Agriculture, Universitas Padjadjaran, from February to May 2022. The experiment used a randomized block design (RBD) with six treatments and was repeated four times. The treatment consisted of giving AMF doses, which included: without AMF, 2 g AMF/plant, 4 g AMF/plant, 6 g AMF/plant, 8 g AMF/plant, 10 g AMF/plant. The results showed that the application of AMF can increase growth and better yield maize. A dosage of 10 g AMF/plant is the best treatment, increasing plant height, cob length, cob diameter, dry shelled weight, and 100 seed weight, each 3, 04%, 5.5%, 8.1%, 50.21%, and 8.42% compared to no AMF.Keywords: arbuscular mycorrhizal fungi, intercropping, maize, oil palm

Abstract

The growth of Liberica coffee in the 2-year immature plant phase can be improved by applying cytokinin-based plant growth regulators (PGRs) and topping. Toppings applied to plants can inhibit apical dominance, while cytokinin PGRs such as 6-Benzylaminopurine (BAP) and coconut water can stimulate plant shoot growth. This research aims to determine the effect of topping and PGR application on the vegetative growth of Liberica coffee plants. This experiment was carried out at the Ciparanje experimental field, Universitas Padjadjaran, West Java, with an elevation of ± 750 meters above sea level from March to June 2024. The experimental design used a randomized block design with six treatments: control (no topping and no added PGR), topping, topping + 60 ppm BAP, topping + 50% coconut water, 60 ppm BAP, and 50% coconut water. Each treatment was repeated four times. The results showed the best results were (a) topping treatments (topping, topping+coconut water, and topping+BAP) on canopy width and primary branch length; and (b) a combination of 50% coconut water and 60 ppm BAP on increasing the number of branches. This study provides information on efficient maintenance methods for Liberica coffee plant growth in the immature phase.

Abstract

Oil palm is a plant that has a long seed dormancy period. The existence of barrier on the seed coat causesdisturbance on imbibition so the process of germination of oil palm seed is hampered. This study aimed todetermine the effect of interaction between the heat treatment by dry-heat treatment method and the submersionof growth regulator gibberellin on oil palm dormancy breaking. The experiment was conducted using a factorialrandomized block design with 2 factors, i.e. 3 levels of dry-heat treatment duration (40 days, 50 days, 60 days)and 3 levels of gibberellin concentration (0 ppm, 100 ppm, 200 ppm) and repeated 3 times. The result showed thatno interaction between the duration of dry heat treatment and concentration of gibberellin on breaking the oilpalm dormancy. Treatment of dry heat treatment of 50 and 60 days had a good effect on percentage of germination,vigor index, radicle length and plumule length. Concentration of 100 and 200 ppm gibberellin had a good effecton percentage of germination, vigor index, radicle length and plumule length. Fifty days-period of dry heattreatment and concentration of 100 ppm gibberellin gave more effective effect than other treatment.Key words : dormancy, Dry-Heat Treatment, gibberellin, oil palm ABSTRAKKelapa sawit merupakan tanaman yang memiliki masa dormansi benih yang panjang.
