Abstract

The research conducted to estimate the heritability value and genetic correlation of growth traits of crossbred F (indigenous hens X Bangkok cocks) were done over 28 weeks. Five groups of pen mating poultry were used in which one cock and five hens were used for each group. Therefore, there were 5 cocks and 25 hens as parent stock and 152 crossbred F. Variables of the research were body weight of DOC, body weight of 4th weeks and 8th weeks. The variations of body weight by sex were eliminated by transforming the female body weight to male body weight using correction factor. Estimation of heritability value (h²) used an anova of nested design method. Estimation of genetics correlation (rG) used an  ancova of nested design. Results of heritability estimates and genetic correlation showed that the h² was 0.13 for Doc body weight, 0. 67 for 4th weeks, and 0,59 8th weeks. The rG was 0.89 for DOC to 4th week body weight, and 0.55 for DOC to 8th week body weight

Abstract

The purpose of the research was to apply sustainable fertilizing system in organic farming                 by System of Rice Intensification (SRI) method. The research was conducted at Sukarasa village, Tasikmalaya West Java. The experiments were conducted using various levels of compost (0, 5, 7.5, 10, 12.5, and 15 tons/acre) and local microorganism (LMO) with different spraying frequencies (0, 4 and 8 times) over the planting season. The results showed that there were no significant effects of yield from organic farming developed by the variety of system introduced above. This result reveals                     no positive correlation between adding more compost and LMO to the yield. The average yield was 4.29 tons/acre. The availability of organic material taken from household garbage and straw                    is 1216. 82 tons. However the need of this organic material to form compost in Sukarasa village is only 922. 35 tons per planting season.

Abstract

The effects of guano and P fertilizer on pH (H2O), available–P and P-uptake of Peanuts in Inceptisols were studied in a pot experiment.  The experiment was carried out from August to November 2007 at the Green House of Agricultural Faculty of Tadulako University.  A Randomized Block Design (RBD) in a factorial experiment was used in which each treatment was replicated three times.  The first factor was guano fertilizer levels: 0 t ha-1; 7.5 t ha-1; and 15 t ha-1.  The second factor was P fertilizer levels: 0 kg P ha-1; 21.85 kg P ha-1; and 43.70 kg P ha-1. The test plant used was Kelinci Variety.The result of the experiment showed that the interaction effect of guano and P fertilizer significantly increased pH (H2O), available-P and uptake-P. The highest increases of pH (H2O), available P and P uptake was found in the 15 t guano ha-1 combined with 43.70 kg P ha-1 treatment.

Abstract

The research was conducted at Dolo District, Donggala Regency from April to June 2007. The aim of the research was to identify the effect of feeding time on income, expenditure and income over feed cost of local cattle. The experimental design used was a Randomized Block Design in which the treatment included were feeding time between 7 am to 5 pm, between 7 am to 9 pm, 7 am to 11 pm, between 7 am to 1 am, and between 7 am to 3 am. The results showed that the effect of feeding time was significant on income of local cattle feed cost, and expenditure, but not significant on income over feed cost of local cattle.
