The discussion focused on the effect of NPK fertilizer named Phonska on the growth rate of red onion, and the crops production. In this study, the method used is descriptive study lasted three months, from July 2011 to October 2011. The data collection techniques used in the preparation of this paper is a randomized block design (RBD ) and documentation . Based on the results, this study showed that the effect of NPK fertilizer Phonska on onion production are very significant. Phonska influence the number of tillers, because it meet the nutrient needs of plants so the crops able to produce well. For better results in the production of red onions we suggested that the cultivation of onion crop use NPK Phonska because it influence the development of onion growth. We recomended the relevant institutions to distribute NPK fertilizer and applying Phonska on onion crop growth to increase the production.

The present work aimed at determining the effects of the association between the periphyton-based system with the bioflocs-based system in the intensive culture of juvenile Nile tilapia (1.56 ± 0.07 g; 72 fish m-3), on variables of water quality, growth performance and effluent quality after 10 weeks. The experiment was arranged in a 2 x 2 factorial randomized block design with four treatments and five repetitions each. The factors tested were the following: ‘underwater structure’ (absence and presence) and ‘adjustment of the C: N ratio of water’ (no and yes). The final fish body weight, specific growth rate and yield were higher (p < 0.05) in the C: N-adjusted tanks. The presence of submerged structures in the tanks had no significant influence on those same variables. It was concluded that the periphyton-based system is not indicated for intensive farming of Nile tilapia, in which there is a high allowance of artificial feed to fish.

<p>ABSTRACT</p><p>Rainfed ricefield, planted at least for one cropping season in a year, depends heavily on rainfall for its water supply. This land generally is low in fertility as indicated by the limited availability of essential plant nutrients in particular nitrogen (N), phosphorus (P), and potassium (K) as well as organic matter. Its productivity is relatively low with a rather erratic precipitation distribution. In order to overcome fertility issue in rainfed land, it is necessary to conduct an integrated nutrient management; one of which is by implementing location specific nutrient management. This study aims to seek the appropriate nutrient management in rainfed paddy field of Semawung village in the sub-district of Andong of Boyolali regency to be provisioned as a technological tool of location specific nutrient management. Research on nutrient management of gogo rancah system-based paddy production was carried out from October 2014 to January 2015. The field experiment was arranged in a Randomized Block Design involving eight treatments and three replications for each treatment. Treatments were combinations of NPK fertilizer, Organofosfat, and straw-based organic fertilizer. Nutrient management using NPK fertilizer and its combination with Organofosfat or organic fertilizer had very significant effect on plant height and number of stem per hill, significantly affected number of panicle per hill, panicle length, and number of fully-filled grain but did not result in difference of fully filled grain percentage and weight of 1000 grains. There was no significant difference between the treatment of 100% of NPK fertilizer and the combination of 75% of NPK fertilizer with straw-based fertilizer regarding these variables: number of stem per hill, number of panicle per hill, panicle length, number of grain per hill, number and percentage of fully-filled grain, weight of 1000 grains, and weight of fresh grain and milled grain yield. Therefore, the latter treatment is feasible as an option of location-specific nutrient management Semawung village.</p>

       Watermelon come from arid tropical and subtropical regions of Africa. Watermelon is an annual plant that grows and requires full sun. Lebak swamp soil is known to have the properties and properties of acid sulphate soils that affect the physical, chemical and biological properties of the soil. Fertilizers are the key to soil fertility. Compound fertilizer is a fertilizer that contains several nutrients, for example nutrients (nitrogen), potassium (K) and phosphorus (P). This study aims (i) to obtain influence and (ii) the best dosage of various applications of NPK Compound fertilizer dosage on the growth and yield of watermelon plants on lebak wetland. The study was conducted in Teluk Buluh Village, Banjang District, Hulu Sungai Utara Regency in July - September 2013, this study used a single randomized block design (RBD) with 5 treatments and 5 replications so that there were 25 experimental units. The factors tested were various doses of Compound NPK fertilizer, namely m1: 0.333 t.ha-1 (200 g / bed), m2: 0.666 t.ha-1 (400 g / bed), m3: 0.999 t.ha-1 ( 600 g / bed), m4: 1,332 t.ha-1 (800 g / bed) and m5: 1,665 t.ha-1 (1000 g / bed). The results of this study indicate that the dosage of Compound NPK fertilizer given to watermelon plants in swampland area had a significant effect on plant length and number of leaves aged 25 HST and 30 HST and had a very significant effect on the fruit weight and number of watermelon plants with the best treatment is  m3: 0.999 t.ha-1 (600 g / bed).
