Abstract. This research aims to determine the effect of broiler manure doses and BiotamaxTM biofertilizers on growth and yield of Chinese cabbage in the Selat Village, Buleleng Regency, Bali from November - December 2018. The randomized block design (RBD) factorial, consisting of two factors was the experimental design used in this research. The first factor is the dose of broiler manure (A), composed of 3 levels, namely control (A0), a dose of 15 tons.ha-1 (A1), and 30 tons.ha-1 (A2). The second factor is the application frequency of biological fertilizers with four levels, namely control (B0) which was administered concurrently for seven days before planting at a dose of 0.09 g.plots-1. B1 with an administrative frequency of 7 and 14 days before and after planting (HST), respectively, with a dose of 0.045 g.plots-1. (B2) with a 3times administrative frequency of 7, 14, and 28 days before, after birth and after each dose of 0.03 g.plots-1 (B3). The results of the study, the frequency of giving BiotaMaxTM biological fertilizer at the same time, provided the heaviest oven-dry weight per crop, which was 9.39 g. The treatment of broiler chicken manure dose of 30 tons.ha-1 (A2), resulted in the best oven-dry weight canopy per plant at 9.26 g. The relationship between the dose of broiler chicken manure with canopy oven-dry weight per plant showed a linear relationship, namely y = 0.0608x + 7.2483 (R2 = 32.53). The best economic weight per hectare is obtained in the provision of 30 tons.ha-1 (A2) broiler manure, weighing 30.10 tons.ha-1. The relationship between the dose of broiler manure and economic weight per hectare shows a linear relationship, y = 0.3247x + 21.699 R² = 59.88%. The frequency of giving BiotaMaxTM biofertilizers at the same time is 7 days before planting at a dose of 0.09 g.plots-1 (B1) gave the heaviest economic weight per hectare, at 28.21 tons.ha-1. The combination of broiler chicken manure dose and the frequency of BiotaMaxTM biofertilizer gave no significant effect (p≥0.05) on the growth and yield of Chinese cabbage.Keywords: broiler manure, biofertilizer frequency, petsaiAbstrak.

Abstract Nowadays, shallot is important horticultural crops in Maluku include in Tual City, Maluku Province. For ensuring the macronutrients level in soil and yield during shallot cultivation, fertilization composed of chemical, organic and bio fertilizer is needed. The objective of field experiment was to evaluate the effect of mixed biofertilizer integrated with organic matter on total nitrogen and available phosphorous in soil as well as shallot yield grown in Vertisols of Tual. The experiment was setup in randomized block design with four treatments of compost and chicken manure amendment with and without biofertilizer containing N-fixing bacteria and P-solubilizing. At the vegetative stage, consortia biofertilizer combined with either compost or chicken manure increased plant height and soil reaction but decreased the available phosphate (P) and didn't change nitrogen (N) total in soil. Chicken manure amendment combined with biofertilizer inoculation increased dry weight of shoots and bulbs even though didn't significantly differ with other treatments. Nonetheles, that treatment resulted in high yield of shallot bulbs up to 14 t/ha.

Dioscorea is potentially used as staple food to support food security. The research was aimed to determine the effect of stake length and time of stem twining on the growth of Dioscorea sansibarensis Pax. The experiment was conducted in Purwodadi Botanic Garden from December 2014 until May 2015 using split plot randomized block design consisted of two factors, i.e. the stake length and time of stem twining. The stake length was the main plot consisted of 150 cm, 100 cm and 50 cm above soil surface and without stake (control). The time of stem twining as subplots, i.e. stem twined early, twined at the time of 4 leaves stage, and twined at 8 leaves stage. Each combination of the treatments was replicated three times. The results showed that there was significant effect on the stake length and the time of stem twining treatments on the plant growth and yield. The stake length of 150 cm treatment produced the highest fresh tuber and total plant dry weight, i.e., 257.24 g and 132.77 g per plant, respectively. On the contrary, the plant without stake produced the lowest fresh tuber and total dry weight of plant, i.e., 112.10 g and 48.65 g per plant, respectively.<br /><br />Keywords: biomass,leaf area, photosyntesis, tuber weight
