Response of Walkwater Growth to Giving of Fishing Waste-Based POC to Inceptisol

Agricultural land that has low nutrient status can inhibit plant growth, so it is necessary to add nutrients to the soil without causing enviromental damage.  The research was aimed to observed growth response of kangkong on combination NPK and level doses of POC fishery wasted on Inceptisol soil.The research was aimed to observed growth response of kangkong on combination NPK and level doses of POC fishery wasted on Inceptisol soil. This research used a split plot design, the main plot consists of: V0 (without used NPK) and V1 (used NPK).Data analysis using variance with the DSAASTAT application. If the variance shows a significant effect, then it is continued with Duncan’s multiple range test (UJBD) at the 95% level of confidence. The results showed  application of POC based on fishery wasted added with NPK can provide a good responses to the heigh of the kangkong plant, the number of kangkong leaves, the fresh weight of kangkong roots and leaves, the dry weight of kangkong roots and leaves and the increase in the number of AMF spores in the rhizosphere of kangkong plants. The best responsed influence of the growth of kangkong plants was combination of NPK and 75% POC doses based on fishery wasted. Utilization of processed fishery wasted as POC can be alternative as an enviromentally friendly organic fertilizer in increasing the yield of kangkong plants

Pengaruh Pemberian Berbagai Pupuk Organik pada Media Tanam Pasir Terhadap Pertumbuhan Tanaman Pakcoy (Brassica Rapa)

Organic fertilizers are materials derived from plant residues, and animal waste, both those that have undergone decomposition and those that are undergoing a decomposition process that functions to add nutrients. Substantially organic fertilizers are composed of humus and non-humus materials so that they can improve marginal soils and sand-dominated soils. The purpose of this study was to determine the effect of various organic fertilizers on sand planting media, and to determine the growth response of pakcoy on various types of organic fertilizers. The research was conducted at the Field Laboratory I Experimental Garden and Agrotechnology Laboratory of the Faculty of Agriculture, Halu Oleo University, the research took place from September to November 2020. This study was arranged in a randomized group design (RAK) with the treatment of various organic fertilizers, which were divided into; no organic fertilizer/control (B0), cow manure (B1), chicken manure (B2), comba-sheep green manure (B3), calopogonium green manure (B4). Each treatment was repeated four times as a group, resulting in 20 experimental units. Each experimental unit consisted of six polybags, resulting in a total of 120 polybags of pakcoy plants. The variables observed were plant height, number of leaves, fresh weight and dry weight of pakcoy plants. The results showed that organic fertilizer had a very significant effect on all observed growth variables of pakcoy plants. Cow manure treatment in the first and second week plant height variables showed the highest value (5.04 cm, and 6.71 cm). But in general, in the third to fifth week, the average chicken manure gave the highest growth response on the variable of plant height, number of leaves, fresh weight and dry weight of pakcoy plants
