Abstract

This study aim of the research is to find  the  growth and production of three varieties of sweet potato in different heights of maps. The resulted conducted in the experimental farm of Faculty of Agriculture,  Hasanuddin University in Makassar from March to July 2011.  The experiment was prepared using the design plots split consisted of 15 cm high, 30 cm and 45 cm high and three varieties of sweet potato as a sub plot, consisting of Japanese variety, Power variety and Purple/Poiret variety.  The results of the research reveal that  Japanese variety produces an average of the highest number of leaves (125.78 strands), the largest number of branches (6.19 strands), the heaviest leaves (164.00 g),  the highest weight of tubers per hectare (19.96 tons / ha ) and highest weight per tuber (171.73 g) The Power of varieties produced on average the heaviest stalk (295.75 g), the heaviest weight of tuber per plant (539.35 g), the heaviest   economical tuber weight per plant  (473.03 g), heaviest biomass (969.44 g), the longest shoots (451.18 cm) and the highest number of tubers (4.77 pieces). The plot with 30 cm high (p2) produces an average heaviest leaves (146.70 g), while the plot 45 cm (p3),  product  an average  longest tubers (14.57 cm).

Abstract

The research was aims to determine the effect of giving types and doses of organic liquid fertilizer on red chili plants. The use of the right type and dosage of fertilizer will affect the production of red chili plants better. The method used in this study used a factorial Randomized Block Design (FRBD) with the treatment of 2 types of fertilizers and 3 different doses of fertilizer then combined, so that there were 6 test treatments. The study was conducted 3 times, so we got 18 units of experimental design. The results showed that the interaction between treatment types and doses of organic liquid fertilizer did not have a real effect on all variables observed for growth components such as plant height and number of branches, but had a significant effect on the observed variables of production components, namely the total sample of fruit plants, sample crop production, and production per plot, with the type treatment and fertilizer dosage of 10 ml / liter of water.

Abstract

This study aims to look at the application of acetoin-producing rizobacteria as biofertilizers for boosting the growth of rice plants in dissolving phosphates and fixing nitrogen. The experimental design used was a randomized block design (RBD), consisting of 6 (six) treatments, 4 (four) treatments with rizobacteria isolates (Rg21 isolates, Pd13 isolates, Pd7 isolates, and Bb7 isolates), one treatment with synthetic acetoin, and one control. Each treatment was repeated 4 (four) times so that there were 24 experimental units consisting of 10 pots of rice plants. The size of the pot used is a surface diameter of 30 cm, filled with growth media in the form of a layer of paddy soil (taken to a depth of 20 cm from the soil surface) and compost with a ratio of 3: 1. The results showed that the treatment of rhizobacteria producing acetoin was able to spur the growth of rice plants by dissolving phosphates that were still bound by colloidal soil so that it was not available for plants to become available P. Likewise, rhizobacterial treatment is able to fix Nitrogen by changing enzymatically organic N compounds into ammonium
