Abstract

Borneo Prima Mandarin (Citrus reticulata cv Borneo Prima) is a new local commodity that grown in lowland but has an interesting orange skin. As a new commodity, Borneo Prima Mandarin has to be developed in order to reduce citrus import. The research was conducted in lowland area (250 m above sea level) IPB research station, Sindang Barang, Bogor from February 2014 to February 2015. The aim of this research was to observe the effect of phosphorus and potassium (PK) fertilizer and pruning on the growth and performance of the plants. This research used Randomize Complete Block Design (RCBD) with two factors. The first factor was aplication of PK fertilizer (15 g P+ 10 g K, 15 g P+ 15 g K, 20 g P+10 g K, 20 g P+15 g K per plant) and the second factor was pruning form (without pruning, open center pruning and hedge pruning). The result showed that the combination of phosporus and potassium fertilizer just gave a significant effect to number of shoot. The highest number of new shoots formed by fertilizing 15 g P+10 g K per tree per application. Pruning treatments had significant effect to plant architecture (i.e reduce plant height, land occupation). Open center pruning and hedge pruning made the crown more open that can increase the light interception so that increase the rate of photosynthesis.

Abstract

Water availability is one of important factor to assure that a field could support increassing rice production value. These descriptive quantitative research aimed to get schedule and amount for irrigation water requirement based on climatic data, soil and crop. Data collected for these research were temperature, humidity, sunshine hours, wind speed, rainfall, plant morphology, altitude and latitude. The research was conducted on July until August 2019. Soil samples was carried out from field area in Koto Perambahan village, East Kampar sub district using purposive sampling method. Data was processed by Cropwat 8.0 software to get amount water requirement for replace the water losss caused of evapotranspiration. Based on weather condition, the field is suitable to plant rice in two season. Irrigation water requirement was writed in decade form, it means for ten days. First planting season occurred on March and irrigation water requirement was 180,6 mm/dec. Second planting season should be done on October with irrigation water requirement was 167,2 mm/dec. The highest irrigation water requirement was estimated on nursery stage, exactly in formation of rice tillers with approximately values 98 mm/dec.

Abstract

Biochar with a high organic matter composition is considered to be an ameliorant for Ultisol. Providing biochar as an ameliorant needs to be studied because it will cause an increase in micronutrients, most of which are excessive in Ultisol. This study aims to determine the effect of several levels of biochar dosage from corn cob as a base material on changes in micronutrients in Ultisol soil. This research was conducted in a greenhouse and in the Laboratory of Agrostology, Feed Industry and Soil Science, State Islamic University of Sultan Syarif Kasim Riau. Experiments with several doses of biochar as treatment, e.g., 0%, 5%, 10%, and 15% of the composition of the growing media were arranged in a Completely Randomized Design (CRD) with six replications. The parameters observed were the micronutrient content of Boron (B), Copper (Cu), Zinc (Zn), Iron (Fe) and Aluminum (Al). The experimental results showed that giving corn cob biochar with doses of 0.5%, 10% and 15% did not significantly change the levels of B, Cu and Zn Ultisol. Biochar at a dose of 10% significantly increased the soil Zn content and decreased Al-dd Ultisol solubility.
