Abstract

This experiment was intended to study effects application time of bokashi cocoa pod husk and dosage of inorganic fertilizer mixture on the growth and yield of sweet corn.  The experiment employed a factorial randomized block design with two factors. The first factor was two levels of the bokashi application time: two or one week before planting time. The second factor was three dosages of organic fertilizer:  133.3 kg/ha of urea + 100 kg/ha of SP-36 + 83.3 kg/ha of KCL, 266.6 kg/ha of urea + 200 kg/ha of SP-36 + 166.6 kg/ha of KCl, and 400 kg/ha of urea + 300 kg/ha of SP-36 + 250 kg/ha of KCl. Data were analyzed with honestly significant difference (HSD) at 5 % significant level. Results showed there was no interaction between the two factors in affecting the parameters observed. It showed that time application of bokashi cocoa pod husk significantly affected the length of corn cob, while the inorganic fertilizer significantly affected the weight of corn cob. Results of the HSD test indicated that the best corn cob length (22.96 cm) was obtained for one week bokashi application prior to planting with inorganic fertilizer of  400 kg/ha of urea + 300 kg/ha of SP-36 + 250 kg/ha of KCl.

Abstract

Exploration of phospate solubizing bacteria (PSB) was carried out to know the population density and diversity of PSB in any rhizospore of vegetation in the area of Lore-Lindu National Park.      The Rhizospore sampling used meyhod of ‘Polar Institu-Bromophenol Blue (NBRI-BPB), Pikovskaya media and Tadulako-2 media. The result showed that 52 isolates of bacteria had been differentiated from 25 rhizospere sample with population density range between 19.0 and 192.5 (x104 cfu g-1), yellow and white of colony colors, and colony diameter between 1.5 mm and 3.5 mm. Screening these bacteria in NBRI-BPB media found 25 isolates classified as phospate solubizing bacteria based on clear zone showed in media. The diameter of clear zone range between 3.0 mm and 4.5 mm. Continuing tested of these 25 PSB isolates showed that seven isolates clustered as superior PSB based on their ability to solve tricalsium phospate in liquid Pikovskaya media with phospate concentration range between 671.5 and 895.7 (mg L-1+ media). These isolates also showed better viability with population density rangr between 87.5 and 142.0 (x106 cfu g-1) after 80 days inoculated in Tadulako-2 media. These seven isolates were SED-01, WUA-07, KAD-08, WAN-03, WAT-03, TAL-02, and ROM-05. Key Words : Exploration, NBRI-BPB, phospate solubizing bacteria, polar sampling plans, tadulako-2 media.

Abstract

The  attack  of  pod borer  Helicoperva  armigera  Huebner  (Lepidoptera:Noctuidae)  on  corn  ear  stems  represent  the main constraint of sweet corn planting development in Donggala Regency Central Sulawesi.  The biological control using a pathogen  insect  (entomopathogen)  as  one  of  the  integrated  pest  control  components  can  be  developed  to  overcome  this problem.  One type of the pathogenic insect is a Beuverria bassiana fungi.The research aims were to identify the effectiveness of various concentrations and application time interval of B. bassiana as bioinsecticide to control of H. armigera pod borer. The experiment used a Randomized Block design with two factors consisting of B. bassiana concentrations (K): k 1 = 0,4, k 2 = 0,6 and k 3  = 0,8, and time interval of B. bassiana applications (W) : w 1  = 5 d, w 2 = 7 d, and w 3 = 9 d.  Each treatment was replicated 3 times; therefore, there were 27 experimental units in total. The parameters observed were: (i) density of larva population (ii) mortality of larva, and (iii) percent of ear corn stem damage.  Data were analysed using the analysis of variance, and differences between means was tested using honest significant difference (HSD) test at 5%. The research results showed that the concentration and the application time interval of B. bassiana each had significant effect on all parameters observed but their interaction effect was insignificant. The treatment k 2 w 3  (0.6 mg B. bassiana/L water applied every 9 d) was more effective in suppressing the population density, the larva mortality and the ear corn stem damage percent than other treatments. Considering the negative impacts of using chemical insecticide, B. bassiana bioinsecticide can be used as an alternative control of sweet corn pod borer H. armigera.
