The Cauliflower (Brassica oleracea L.) PM 126 F1 is one of the vegetable commodities with a high enough demand because this vegetable is widely consumed by the public. This experiment purposes to get a dose combination of oyster mushroom waste organic fertilizer and NPK fertilizer which gives the highest growth and yield of cauliflower. The method of research used is the experimental method. The design of experimental used was randomize block design (RBD) with a single factor that consisted of 8 treatments with 3 replications, that is : A (control), B (10 ton/ha Organic fertilizer), C (20 ton/ha Organic fertilizer), D (30 ton/ha Organic fertilizer), E (NPK 800 kg/ha), F (10 ton/ha Organic fertilizer + NPK 800 kg/ha), G (20 ton/ha Organic fertilizer + NPK 800 kg/ha), H (30 ton/ha Organic fertilizer + NPK 800 kg/ha). the result highest curd weight is 7,75 ton/ha achieved by treatment G is 20 ton/ha waste compost of oyster mushroom and 800 kg/ha NPK fertilizer.

ABSTRACTFinding the appropriate method of fertilizer application to simultaneously enhance farm productivity and ensure ecosystem sustainability has been receiving a lot of attention. A field experiment was carried in the Research Plot Agriculture Faculty Bengkulu University Campus Indonesia in 2017. The purpose of this study was (1) to assess the significant effects of inorganic N fertilizer (IF) substitution with bio-fortified compost (BC) under equal N conditions on growth, N accumulation, and yield of sweet corn, and (2) to determine the appropriate level to which inorganic N fertilizer could be reduced and equivalently replaced by bio-fortified compost to promote sweet corn growth and yield. The treatments consisted of six different proportions of inorganic N fertilizer (IF) substitution with bio-fortified compost (BC). Each treatment was designed on the basis of equal amount of total N input from a combination of both fertilizers (138 kg N ha-1).  They were arranged in a randomized block design with 3 replications. They included (1) 100% IF plus 0% BC, (2) 75% IF plus 25% BC, (3) 50% IF plus 50% BC, (4) 25% IF plus 75%, (5) 0% IF plus 100% BC, and (6) no IF and no BC. The results showed that the increasing proportion of IF replaced by BC resulted in an increase for all variables (except for plant height) but they decreased when 100% IF substitution with 100% BC was applied. Among the partial substitution treatments, 50% IF plus 50% BC consistently produced the best growth, N accumulation, and yield increase. Treatments of 50% IF plus 50% BC and 25% IF plus 75% BC produced the highest green cob weight with husk per plot (10.74 – 10.84 kg plot-1), which was 16% to 19% higher than treatment of 100% IF plus % BC. The three partial substitution treatments produced crop yield components as good as treatment of 100% IF plus 0% BC. Treatment of 0% IF plus 100% BC reduced plant growth, N accumulation, and crop yield and its components. The appropriate level to which IF could be reduced and equivalently replaced by BC was at the range of 25% to 75%. Hence, a suitable replacement of inorganic N fertilizer with bio-fortified compost is considered a reasoned way to simultaneously increase crop yield and reduce environmental degradation.Keywords: organic fertilizer, chemical fertilizer, bio-fortification, chemical fertilizer substitution, bio-fortified compost

The use of inorganic fertilizer in agriculture as well as on sweet corn cultivation is quite high. Inorganic fertilizer recommended for sweet corn is  35 kg urea ha-1, 150 kg TSP  ha-1 and 150 kg KCl ha-1. Besides high prices, its difficult to find when needed. To overcome this, an experiment was carried out by utilizing TM plants for reducing urea input. This research was carried out in Air Kuti Village, South Lubuklinggau District I, Lubuklinggau City, South Sumatera Province with an altitude of 110 meters above sea level (ASL), from April to June 2017. The experiment was arranged out in a randomized completely block design (RCBD) factorial 4 x 3 and repeated three times. The first factor was treatment combination of inorganic N fertilizer (urea) and TM plants consisted 4 kinds i.e: 75% urea and 1 TM plant, 50% urea and 2 TM plants, 25% urea and 3 TM plants, and 0% urea and 4 TM plants. The second factor was a frequency of urea application consisted of 3 levels i.e: 1-time application 15 days after planted (15 DAP), 2 times application (15 and 30 DAP), and 3 times application (15, 30 and 45 DAP). The results showed that application of urea fertilizer dosage of 25% recommended (108,75 kg urea ha-1) combinated with 3 stem of TM plants produced the best growth and yield of sweet corn. The frequency of urea application 3 times produced the best growth and yield of sweet corn.

This research was purposed to find out whether there was any significant correlation of the composting time of teak sawdust and EM4 dose on the growth and yield of lowland flower cabbage plants or not. This research was carried out at the Experimental Field of Universitas Merdeka Pasuruan (Sultan Agung Street), Pasuruan City at an altitude of 4 m-asl. This research used factorial Randomized Block Design (RBD) method consisted of two factors and repeated three times. The first factor was the length of composting (L) with L1: one month, L2: two months and L3: three months. The second factor was the dose of EM4 (D) with D1 : 10% EM4 dose, D2 : 20% EM4 dose and D3: 30% EM4 dose. Overall there were nine combinations of treatments. The results showed that there was 20% EM4 dose with a 2 months composting time yielded higher results on all observed parameters. Flower cabbage with a dose of 20% EM4 with composting time of 2 months produced fresh weight of 15.97 tons ha-1, at a dose of EM4 20% with a composting time of 1 month produced fresh weight 13.86 tons ha-1, while the lowest yield at dose of 20% EM4 with a composting time of 3 months produced fresh weight 9.79 tons ha-1.
