Abstract

In a long dried season, oil palm plant that planted in peat soil will hindered by drought stress. Drought stress is one of the main limiting factors in growth, nutrient uptake and yield of oil palm. One of the alternatives to overcome this drought stress problem on many plants is through inoculation with AMF. This research was conducted to observe the adaptability of oil palm seedling inoculated with AMF on drought stress in peat of used forest soil.  The experiment on this soil type was arranged in a Factorial Completely Randomized Design with two factors. The first factor was AMF inoculation (M0= without AMF and M1 = inoculation of AMF) and the second factor was drought stress levels (available water 100%, 75%, 50% and 25%). Research  result indicates  that AMF inoculation improved the adaptability of oil palm seedling on every level of drought stress, as shown by the responses of growth and nutrient uptake. The adaptation of non-inoculated seedling on drought stress was solely by tolerance mechanism, either osmoregulation as shown by higher production level of osmoticum components or cell turgor regulation by leaf ABA accumulation. On the inoculated seedlings, however, there were synergism between those two tolerance mechanism and escape mechanism.  Two important escape mechanisms were intensifying root system and decreasing transpiration surface of seedlings.   Key words : oil palm, AMF, drought stress, adaptation mechanism

Abstract

Oil palm (ElaeisguineensisJacq) is a plantation which plays an important role for Indonesia as the leading commodity for export or for the commodity that is expected to increase farmers' income. Of the various factors that cause the production of palm oil decreased by one of them is the problem of drought during the dry season as it is known that palm oil has a shallow root system (root fibers) so that the easy availability of water shortages. This research was carried out experimentally by using Completely Randomized Design (CRD) consisting of4 treatments with 3 replications, so there are 12 experimental units. Each unit consists of two plants were taken 1 (one) of plant samples. The tested combined treatment consisting of four levels: A (The Water 2400 ml Marihat D × P), B (Giving Water 2400 Topaz ml D × P), C (Provision of Water 1200 ml Marihat D × P), and D (Provision of Water 1200 ml of D × P Topaz). The parameters observed were plant height increment, number of leaves, corm girth increment, dry weight, seed quality index and proline content. The data obtained were analyzed using ANOVA and followed by further tests DNMRT at level 5%. Result showes that treatment of water supply volume provides significant results on the observation parameters plant height increment, whereas the parameters observed in the number of leaves, corm girth increment, dry weight, and seed quality index showed no significant results after further testing DNMRT at   5%  level   Key words : water supply,  corm girth, drought.

This studyaims at determine the interactionbetween the different level of 2.4-D andTDZ concentrations, to induction theembryogeniccallus of physic nut. This Research used completely randomized design with factorial treatment pattern, which consists oftwofactors :concentration of2,4 –D, which consists of 5levels : 0.0, 2.5,  5.0,  7.5, 10.0 ppm, and the concentration ofTDZconsists of 5levels: 0.0,  0.5,  1.0, 1.5, 2.0 ppm. The results showes that there are interactions between 2,4-D andTDZ to  formingcallus   ofthe apicalbudexplants of physic nut.The combination of5.0 ppm2,4-D + 1.0ppmTDZand7.5ppm2,4-D + 1.5ppmTDZproducedthe time appearing of callusfastestcompared toother  treatments.

Abstract

The potato cultivation in the highland area has been redistricted due to the facts of small area that suitable for potato cropping. The suitable landispurposed to be conservation practice. Therefore, inorder to increase potato yield could be established by the expansion to the lowlands area. But in the lowlands has been redistricted by the negative effects of high temperatures for tuber formation and the lack of well adapted variety. Those limitations could be overcome by finding the well variety that could be adapted in the lowland. The experiment aim is to observe the adapted cultivars. The treatments arecultivars: Granola I (G2), DTO 28, Atlantik andtwo varieties, Granola II (G3) and Eigenheimer (highed land at Jambi Provincial). The parameter to evaluate is number of tubers, tuber growth rate, sinc strength and source strength. This experiment used Randomized Block Design (RBD). The results shows that the  highest source strength, sinc strength, tuber weight per plant, numbers of tubers, and tuber growth rate was achieved at variety Granola II. Key words:  sinc, source, tuber formation.

Abstract

This research aim is  to evaluate the effect of Palm oil liquid waste  to the cacao seedling growth. This research was conducted at Faculty of Agriculture Research Farm. This research was arrangement with Completely Randomized Block Design (CRBD) consisting of  six treatment of dosage with  four replications, so there are 24  polybag. The treatment are  dosage 0.0 Lpolybag -1 , 0.4 Lpolybag -1,0.8 Lpolybag -1, 1.2 Lpolybag -1, 1.6 Lpolybag -1 dan 2.0 Lpolybag -1. The Results showed  that there were significantly effects of dosage to all growth parameter, such as cacao seedling height, diameter of branch, total leaf area, root dry weight and plant dry weight. Dosages 1.6 L polybag-1, was the best effect on all growth parameters.
