Abstract

The purpose of this study was to analyze the effect of inputs on wetland rice production and to determine their efficiency on wetland rice production in Toribulu Village of Toribulu Sub District, Parigi Moutong District. This study was conducted during March to May 2014. The number of respondents was 33 farmers out of 129 wetland rice farmer population selected using a simple random sampling technique. Data was analyzed using the cobb-douglas function and efficiency analysis. The input factors i.e land area (X1), seeds (X2), NPK fertilizer (X3), labor (X4), and pesticides (X5) both simultane ouslyand partially had significant effecton the rice production (Y). The coefficient of determination (R2) was 0.983 indicating that 98.3% of the variation in the variable factors of the rice production can be explained by all variables observed (Xi), while 1.7% is caused byother factors not included in the model. The efficiency scores of land area (X1), NPK fertilizer (X3), labor (X4), and pesticides (X5) were greater than 1 while seed (X2) was less than 1 suggesting that the former inputs used in the wetland rice production are not yet efficient but the latter is efficient in terms of price.

Abstract

This study aimed to determine media compositions supplied with BAP and IBA suitable for the growth of black grape shoots. This research was conducted at the Laboratory of Plant Biotechnology, Faculty of Agriculture, University of Tadulako, during April to September 2016. The study used a factorial completely randomized design. Two factors were tested, the concentrations of BAP i.e. 1.50 ppm, 2.00 ppm and 2.50 ppm; and the concentration of IBA i.e. 0.00 ppm, 0.25 ppm and 0.50 ppm. There were nine treatment combinations and each combination treatment was replicated three times to obtain 27 experimental units. Each experimental unit using an explant. Data were analyzed using analysis of variance and followed by Honestly Significant Difference test at level of 5% if the treatment effects were significant. The results showed that the composition of the culture media supplied with 2.00 ppm BAP without IBA is able to stimulate the formation of black grape leaves at the earliest, at an average of 18.67 days per explant, while the media added with 2.00 ppm 0.25 ppm BAP together with IBA can lead to longest shoot growth, at an average of 2.13 cm per bud. The culture media applied with 2.50 ppm BAP can trigger earliest shoot growth and highest number of leaf formation which were 11.11 days after culture and 2.44 leaves per explant. Earliest formation of black grape shoots of 11.89 days after culture is stimulated by the addition of 0.25 ppm IBA.

Abstract

An experiment was conducted at the research station of animal husbandry departement, Agricultural Faculty, University of Tadulako Palu. This experiment was carried out from April to March 2008. The objective of the study was to determine the effect of various ages of female local goats on the onset and intensity of estrus. 18 non pregnant local female goats and 3 males as teaser to detect estrus were used in this experiment. Experiment consisted of two stages; preparation period and observation period. At the first stages the animals were adaptated to the experimental condition, such as feeding concentrate and injection of PGF 2α to syncronize estrus. The estrus syncronization was done by applying twice injections of PGF 2α at day 1 and day 12. The observation period for detection of the estrus onset was done by observing the time interval between injection of PGF 2α and the first estrus onset. This parameter was expressed in hour unit. Observation of estrus intensity was done by detecting level of estrus symptom appeared to every single female goat. The symptom was characterised by different behavior of the goat females at the time of estrus and changes of physical reproductive organs. The results of analysis indicated that different ages significanly affected (P<0.01) the estrus onset and intensity of the animals. The estrus onset of the local goat after estrus syncronization took place at hour 70.06 to 138.42. The onset of estrus was earlier for animals which already gave birth more than once.  The animals which had never given birth were the last ones which showed the estrus. The estrus intensity was evident in the animal given birth more that once, whereas for those animals which only experienced giving birth once the intensity was less evident.
