Abstract

The purpose of the study was to select several Trichoderma sp based on its sporalation capabilities, and antagonistic character, and effectiveness to control P. palmivora on cocoa pod.  The study consisted of two stages. In the first stage, a Completely Randomised design was used which consisted of seven treatments with three replicates: T. viridae, collection of  Laboratory of Plant Pest and Diseases of Bogor Institute of Agriculture (T-A), T harzianum, collection of Laboratory of Plant Pest and Diseases of Bogor Institute of Agriculture (T-B), T harzianum,  collection of  Coffee and Cacao Research centre of Jember (T-C), T koningii, collection of  Coffee and Cacao Research Centre of Jember (T-D), T. Trichoderma sp 1, collection of Laboratory of Microbiology  Life Sciences Centre of Bandung Institute of Technology    (T-E), Trichoderma sp 2, collection of Laboratory of Microbiology  Life Sciences Centre of Bandung Institute of Technology (T-F) and Trichoderma sp, collection of Laboratory of Plant Pest and Diseases University of Tadulako (T-G). Parameters measured were sporulation capability of Trichoderma sp, percentage of antagonisticity of Trichoderma sp towards in vitro P. palmivora . The second stage of the study was to determine the effectiveness of Trichoderma antagonisticity, either individual or mixed cultures in controlling the development of  P. palmivora on cocoa pod. The study was designed with seven treatments with three replicates:  T-D, T-E, T-G, T-DE  (mixed culture of T-D and T-E),  T-DG  (mixed culture of T-D and T-G), T-EG ( mixed culture of T-E and T-G), T-DEG (mixed culture of  T-D, T-E, and T-G). The results of the study showed that at in vitro condition the kinds of Trichoderma sp which had the highest antagonisticity on P. palmivora were  Trichoderma sp (T-G, T-E and T-D). They were effective to control P. palmivora on cocoo pod either in individual or mixed cultures.  However, T-G will be further developed due to its highest effectiveness as a biological control compared to the others.

Abstract

The  objective of the research was to identify  the level of soil development in paddy soil in Kaluku Tinggu Village Donggala Regency Central Sulawesi. The method used in this research was a survey method in which observation and soil sample were taken systematically using a grid system.  The distance between observation points was 250 m.  The observation on soil sample distribution is carried out by using soil auger.  Soil profile for observation of soil morphological characteristics was determined based on the result of the soil auger data.  The data of soil resulted from field and laboratory analysis were used to compare soil characteristics among horizon.  The average of each parameter was calculated using formula of balance average. The morphological soil characteristics observation on paddy field showed that the profile thickness was 0-80 cm, horizon thickness  >12 cm, soil color was  grayish to grayish red, texture was sandy loam and clay loam, soil structure was granular and rounded blocky, and soil consistency were sticky and plastic. Such soil characteristics indicated that the soil development was at a recent stage.  A long period under submerged condition has impeded the soil development.

Abstract

The study to identify the effects of different concentrate supplementation on the reproductive performance of the local rabbits fed with basal ration (i.e.: sweet potato forages – ad libitum) was carried out in Jono Oge village - Biromaru, Donggala–Central Sulawesi. The study used 12 multifarious does which were allocated to four treatments using a Randomized Block design (RBD).  The treatments were as follows: does fed with basal ration (R0); does fed with basal ration supplemented with concentrate at 1% (R1), 2% (R2), and 3% (R3) of body weights.  Litter sizes, weights at birth   and weaning of kids were then recorded.  Results showed that concentrate supplementation for the  local rabbits fed with basal ration of sweet potato forages did not significantly affect the litter size and  birth-weight of kids but the treatments did significantly affect their weaning-weights (21 day old).

Abstract

The research aim was to identify the effect of liquid organic fertilizer at low dosage on weeds growth and corn yield in no tillage agriculture. The research was conducted in farmer’s land in Donggala Regency, and in the laboratory of agricultural Faculty of  Tadulako University from May 2007 to  September 2007. The research used a Randomized Block Design in a Factorial experiment with three replicates.  Two factors applied were no tillage agriculture and complete liquid fertilizer. The first factor included no tillage (TOT), TOT + mulch, TOT + glysofat, and TOT+mulch+glysofat.  The second factor consisted of no fertilizer, complete liquid fertilizer at 1/3 recommended dosage (1 L ha-1), complete liquid fertilizer at 2/3 recommended dosage (2 L ha-1), and complete liquid fertilizer at equal to recommended dosage (3 L ha-1).  The research results showed that there was no interaction effect on weeds dry weight ha-1, dry kernel yield ha-1, 100 kernel weight, kernel number per cob, and cob length.  The NJD of weeds changed from broad leave weeds group of  Alternanthera sessilis (L.) DC to teky weeds of  Cyperus rotundus L. The no tillage+mulch+ glisofat treatment resulted in the lowest weeds dry weight of 20.556 g, the highest dry kernel yield of 4,338 ton ha-1, and 100 kernel weight of 34.876 g.

Abstract

The study was aimed to estimate the body weight of Donggala sheep based on their body length and chest diameter using Lambourne and Schoorl equations.  Survey method was used to select the sheep randomly from east Palu, west Palu, and Biromaru. The research results showed that the correlation value of chest diameter with body weight was higher than that with body length. Additionally, t test values of Lambourne and Schoorl equations were lower than the t-Table. This indicates that the body weight of Donggala sheep resulting from direct weighing and from those two equations was no significantly difference. Therefore this study suggested that Lambourne and Schoorl equations are feasible to use for estimating the body weight of Donggala sheeps.

Abstract

The research aimed at determining the age of nangka rootstock and the level of Nutrifarm-SD fertilizer on the successful knitting of grafting.  The research was arranged in a Randomized Block design in a factorial experiment in which grouping was based on the rootstock length.  Two factors applied included the age of the rootstock: 1 month after sowing (BST), 2 months after sowing, and                 3 months after sowing and the levels of Nutrifarm-SD: control, 5 g seed kg-1, 10 g seed kg-1, and 15 g seed kg-1.  Grafting using younger rootstock (1 month after planting) resulted in the largest number of successful bonding.  Either the single effect of Nutrifarm-SD fertilizer or combined effect with the age of the rootstock was insignificance on all parameters observed.
