Abstract

The Study of the Droght Stress and The Nitrogen Fertilizer Doses For the Plant Gogo Produce. The research had taken place in glasses house BPTP Naibonat Kupang from Junni to October 2008. The aims of the research is  to know the influences of the value of the drought sress and the nitrogen of Fertilizer doses for the  product of Rice plant Gogo. The research was done by using Randomized Complete Design factorial research which consist of two factors which is used without barren, the droght stess  21 -25 HST, 76 -80 HST and 111 – 115 HST. The secont factor is Nitrogen fertilizer doses which used and without nitrogen fertilizer, 45 kg N/ha, 90 kg N/ha and 135 kg N/ha, with 3 replication. The variabel which observed is the number of plant seed, the panicle number the qualiy of one thousand seeds, the qualiity of the seeds, and harvest index per plantation. The result of the research souws that the effect of drounght and doses nitrogen fertilazer of Riceland field for the fariabel which observed is seed number, the seed quality and the quality of the seed per plantation. The treatmen of the second droht stress (C2) with nitrogen fertilizer doses 90 kg/ha (N2) gives the average seed quality per plantation, whichis higher  than the onther tretment.Keywords: Droght Stress, The Nitrogen Fertilizer Doses and Plant Gogo Produce

Abstract

Strategy of dryland farm management in improving food security in East Nusa Tenggara; One of the promising opportunities but often to be neglected is the use of arable dryland suitable for food crops production, The potential of available dryland agroecosystems is quite extensive and technically suitable for agriculture. The potential land will be able to produce sufficient food if managed using effective technology and appropriate development strategies. Strategies for utilizing potential dry land are: 1) emelioration measures to improve soil quality by utilizing in-situ local resources 2) increased land productivity and sustainable commodity production of dry land sustainably, and 3) rain harvesting  technology, and 4) improvement of economic infrastructureKeywords: Dryland, land management strategy, food security

Abstract

Model Plan Usahatani Conservation As Dry Farming ProductivityEnhanced Efforts. In the effort erosion trouble-shooting and the low of dry farming productivity, has been executed serangkian research which in focussed in area of Praktek Politani Kupang having location in Oesao Kabupaten Kupang. Research aim to study specific usahatani model of dry farming. Three kinds of model usahatani conservation has been checked, yakti bench terrace, terrace;core gulud and without terrace;core. Measurement of level of erosion is done in emperis with method USLE. To evaluate farm productivity also is done cultivation of green peanut crop Result of research indicates that technically, model usahatani conservation of bench terrace and terrace;core gulud gives repair impact to degradation of erosion speed and improvement of farm productivity. Bench terrace earns effectively lessens erosion until under admissible erosion boundary, however memerlukn technical clauses in its(the making in order not to harm plant growth. Terrace;core gulud is one of alternative of conservation that need to be considered, especially at soil;land;grounds having [shallow/ superficial] solum, because cost in its(the making is cheap and doesn't require many labours, and top layer soil is not annoyed.

Abstract

The aim of this study was to evaluate the effect of application of biourin fertilizer and Mycorrhizal Vesicles Arbuscula (MVA) dosage on P dynamics, P uptake and yield of shallots in vertisols. This study was designed with a factorial design pattern on the basis of a randomized block design (RBD). The treatment tested was the concentration of  biourin (B), with four levels: B10: Concentration of 10 ml.l-1 water, B20: Concentration of 20 ml.l-1 water, B30: Concentration of 30 ml.l-1 of water and B40: Concentration 40 ml.l-1 of water. The second treatment was MVA dose with four levels, namely: M0: Without MVA, M10:10 g.plant-1, M20: 20 g.plant-1 and M30: 30 g.plant-1.  The results showed that the biourin concentration of 40 ml.l-1 of water and the MVA dose of 30 g.plant-1 significantly affected the dynamics of available P in Vertisol. The application of biourin at a concentration of 30 ml.l-1 water showed a P absorption of 15.07% and increased shallot yields by 41.07%. The best application of MVA biofertilizer in vertisols was achieved at a dose of 30 g.plant-1, able to increase plant nutrient P uptake by 152% and increase shallot yield by 72.38% from without MVA.Keywords: Concentration of biourin; MVA dose; P dynamics, Shallot yield

Abstract

Calcareous soils have great potential for the development of food crops and horticulture, but they are constrained by high pH, low organic matter content, and less than optimal cation exchange capacity, thus affecting the availability of nutrients. This study aims to evaluate the effectiveness of organic fertilizer enriched with humic acid on soil chemical quality, nutrient uptake, and yield of shallots on calcareous soils. The study was designed with two factors, namely type of organic fertilizer (manure and bokashi) and concentration of humic acid (0%, 10%, and 20%) added to the organic fertilizer. The results of the study showed that the application of organic fertilizers, both manure and bokasih, had a similar effect on soil quality and shallot yields. However, the addition of humic acid at a concentration of 20% significantly improved the chemical properties of the soil, nutrient uptake (especially nitrogen and potassium), as well as the yield component of shallots when compared to the concentration of 10% and control. The addition of humic acid has been proven to be effective in improving nutrient availability and supporting plant growth. This innovation can be an effective solution to improve the quality of calcareous soils and agricultural products, especially shallots, which supports sustainable and environmentally friendly agriculture. Keywords: Calcareous soil, Humic acid, Nutrient uptake, Organic fertilizer, Shallots.
