Abstract

Nitrogen is a major nutrient for plant growth, nitrogen was absorbed by plant roots in the form of NO3-(nitrate) and NH4+ (ammonium). Nitrogen deficiency affects negatively on plants, like stunted plant, leaf turns yellow, and limited rooting system, while excess nitrogen causes elongated vegetative growth, easy to fall down, reduce the grain quality and its response to pests and diseases. The purpose of this study is to determine the available soil-N, plant N uptake and growth as well as the yield of paddy rice (Oryza sativa L) due to the treatment of straw compost and NPK fertilizer. Treatment was carried out in a factorial experiment designed in randomized block design, the straw compost factor consisted of  two dose levels: 0 and 3.0 ton ha-1 and NPK fertilizer factor consisted of five dose levels: 0, 75, 150, 225, and 300 kg ha-1 with three replications. Research findings indicated that the amendment of straw compost together with NPK fertilizer increased the plant uptake of N, but straw compost improved independently the soil-N, and plant growth (plant height and number of tillers/clump). Likewise, NPK fertilizer independently increased soil-N, growth parameter (plant height and number of tillers/clump) and grain yield (number of grains/panicle and number of filled grain/panicle). The straw compost amendment at 3 tons ha-1 along with 150 kg NPK ha-1 resulted the highest N-uptake of 3.51%.

Abstract

Land degradation on the upper stream area in Ambon island has reduced the availability of fresh water for the peoples. An available fresh water supports only 19.14% of total population.  This research was carried out to solve the problem of water resources shortage in Ambon city which is sourced from Batugantung.  The objectives of this research were to evaluate the impact of land use changes on the income, hydrological characteristics, erosion and sedimentation in Batugantung watershed. The result of this research showed that the increasing density and coverage of vegetation can increase the sustainability of land and water resources.  The increasing vegetation density in agroforestry land use can imitate the role of forest in sustaining watershed hydrological function, decreasing runoff, controlling erosion as well as  increasing farmer’s  income.  By keeping  at least 30% forest in dusun land use management in  Batugantung watershed, it can sustain water yield about 75.66 liters.s-1, decrease erosion to 27.62 ton.year-1, and increase farmers income up to Rp. 15.64 million ha-1.year-1.   By applying  the result of this research to other watersheds in Ambon island, the availability water resources will be about 13.07 x 105 m3.day-1. This amount of water resources can fulfill present total requirement of fresh water for  380 thousand peoples in Ambon island which is only  6.08 x 104  m3.day-1.

Abstract

In developing productive forests, seeds play a crucial role. The seeds of forests tree have physical condition of hard seed coat, especially Leguminoceae family. Silvicultural techniques that can overcome seed coat dormancy are dyeing and submersion of seeds. The knowledge and experience in breaking seed dormancy of Sengon (Paracerianthes falcataria L.) is rare, therefore it is necessary to study how to overcome seed dormancy. The objective of this study was to determine the effect of dyeing and submersion treatments to overcome seed dormancy of Sengon seed to improve its viability. This research used Completely Randomized Design (CRD) with two factors: namely Seed (Factor A), dipped in hot water at 60 º C for (A0 = Control, A1 = 2 minutes, A2 = 4 minutes, A3 = 6 minutes), Factor B, seeds soaked in cold water: (B0 = control, B1 = 6 hours of soaking, B2 = 12 hours, B3 = 18 hours, B4 = 24 hours). The parameters observed were germination percentage, germination rate and vigor index. The results showed that among all parameters observed the interaction of factors A1B2, A2B2 and A3B2 were the best treatment for germination percentage which was equal to 100 percent, the best germination rate of 3.897 days and the best vigor index of 27.02
