Abstract

Nitrogen is the most dominant element affecting plant growth compared to other elements. Whereas Fe is rare. The occurrence of symptoms in parts of the plant (especially leaves) is then expressed as a lack of Fe availability because of the imbalance in the Fe availability with Calcium in the soil which is excessive on Calsium and alkaline. The purpose of this research was to knowing the symptoms of agility and poisoning of macro and micro-nutritional elements on physiological properties and growth of tomato plants. The research had been conductedin January - March 2017 at Green House and Laboratory of Agriculture of STIPER Petra Baliem Wamena, Papua. The treatments were assigned in Completely Randomized Design with addition of N and Fe i.e. without Fe (-Fe), 3x Fe (3Fe), 3x N, treatment of N + Fe (complete) and without N (-N), then followed by Duncan's multiple ranges test at level 0.5. The results showed the treatment of 3xN and 3xFe of the Hoagland dose 2 solution had not reached the maximum level so that it had not shown any toxic symptoms, symptoms of N deficiency were chlorosis (pale green to yellow) in old leaves, stunted growth, and more leaf necrosis bottom in cases of severe N deficiency, and 3xFe treatment of Hoagland 2 doses resulted in the lowest plant height estimated due to iron toxicity. Keywords: Hara, Physiology, Pomatoes

Abstract

ABSTRACTThe main problems of rice cultivation in Ultisol medium are acid reactions, Al saturation and height P fixation, as well as low availability macro, micro nutrients especially Mo and Si. Rice plants need silicate in large quantities even though it is not an essential nutrient, therefore husk ash can be used as a source of Si. Pavailability increased by applying P fertilizer which was classified as slow realease so that fixation can be supported. The research aims to study the interaction of rice husk and rock phosphate is able to improve Si and P uptake and the growth of upland rice growth on Ultisol medium. The research was conducted at the Green House of the Faculty of Agriculture, University of Riau, Pekanbaru from January to March 2019. The research in form factorial experiment 4×3 was arranged in a completely randomized design, 3 replications. The first factor wasrice husk consist of 4 levels (0, 1,5, 3, and 4,5 ton ha-1). The second factor wasrock phosphate consist of 3 levels (0, 25, 40 kg P2O5 ha-1. The results showed the application of rice husk dose of 3 ton.ha-1 and rock phosphate dose of 25 kg P2O5 ha-1 increased Si and P uptake, P uptake efficiency, the root volume, dry weight, root canopy ratio, and plant growth rate.

Abstract

ABSTRACTSugar Palm (Arenga pinnata Merr,) has a high economic value and has the potential to be exported and can be processed into a variety of food and non-food products. Sugar palm is a multipurpose tree because all parts of the tree can be used, such as stems, palm sap, leaves. Characterization of local palm trees had been carried out in Pandegelang, Serang, and Lebak Regencies (Banten Province) which were used as making nursery material to make better sugar palm in the future (superior varieties). This study used a survey method based on guidelines for plantation germplasm management from the Indonesian Plantation Research and Development Center. The results showed the diversity of stems and leaves of palm trees in the three districts. The diversity of stem phenotypes on sugar palm was seen in the height and circumference of the stem. Diverse appearance of palm leaves seen in the length and circumference of the ptiole, the length of the rachis, the length and width of the leaflets. The study conclude that the accessions used in this study showed variations in the appearance of stems and leaves from the accessions of palm trees observed.

Abstract

ABSTRACTKnowledge of good fertilization for oil palm on smallholder farmers is still limited.The availability of fertilizer knowledge both from primary sources and in theliterature as a secondary source, does not make it easy for farmers. An expert system is built in the form of a mobile application to implement the available knowledge base to provide fertilizer recommendations. The oil palm fertilization expert system in this research is called SmartFerti. SmartFerti is developed with a reasoning approach using a forward chaining method. The application design is based on the type of nutrients, planting density (stand per hectare, SPH), land area, type of fertilizer, and location. SmartFerti was built using 8 knowledge bases collected from reputable sources which were processed to obtain conclusions. SmartFerti provides fertilizer recommendations which include doses per semester and application time for 11 provinces in Indonesia. Nutrients that can be recommended include nitrogen, phosphorus, potassium, calcium, and magnesium. SmartFerti fertilization expert system uses an android-based interface built using App Inventor 2,0 (www,appinventor,mit,edu).
