Abstract

This study aims to determine the total costs, production volume, sales price and the amount of farm income in the village paddy Baluase South Dolo Sigi Districts. The research was conducted in January and February 2015. The Respondent is done by simple random sampling method (Simple Random Sampling), dengan consideration the number of respondents who were taken in the study of 20 farmers. The analysis used in this study is an analysis of income. The results showed that the average/ha income received by farmers for rice farming rice fields where the use of balanced fertilizer sebesar average income of Rp 20.91405 million/ha, while the average income does not use a balanced fertilizer Rp 8.2358 million /Ha. By means paddy rice farming which uses balanced fertilizer gave the comparison of real incomes by not using balanced fertilizer. Key Words: Comparative analysis of revenue paddy balanced and unbalanced fertilizer.

Abstract

The purpose of this study was to evaluate the response of the growth of the rice plant (Oryza sativa) local cultivars at different levels of soil moisture. This study uses a randomized complete block design consisting of (1) Cultivars Rice locally as the first factor consisting of (K1) = rice cultivars Ranta, (K2) = rice cultivars njengi and (K3) = rice cultivars Sampara, (2) the level of moisture soil as a second factor consisting of (T1) = The level of moisture the ground 100% (field capacity),              (T2) = level of moisture the soil 75%, (T3) = Level moisture soil 50% and (T4) = rate of moisture land 25% , The results showed that the cultivars njengi generating plant height and stem diameter is greater than the other cultivars. Ranta cultivars showed the number of leaves, number of tillers and leaf area were higher than the other cultivars. Soil moisture level of 100% (field capacity) also results in plant height, number of leaves, number of tillers, leaf greenness (chlorophyll) and a trunk diameter greater than with other soil moisture levels. Key Words : local cultivars, rice, soil moisture.

Abstract

This research aimed to identify factors influencing rubber production of people plantation in of Pontangoa village LemboRaya sub-districton North Morowali Regency. This research was carried out in November – December 2015. Respondents were determined using a Random Sampling Technique. The number of the respondents was 31 families selected from a population of 407 farmers. Data was analyzed using the Cobb-Douglas analysis. The results showed that all the variables are simultaneously highly significant affecting the production of the rubber, where F-counted is 545.377 > F-table (3.85) at α of 5%, thus H0 is rejected and H1is accepted.Such factors as land area, plant number, and labor have partially significant effect on the rubber production as shown by t-counted of land area (4.759) is >t-table (2.478), t-counted of plant number (6.236)>t-table (2.478), and t-counted of labor (-2.567)>t-table (2.478) suggesting that the H1 for these factors is accepted.  By contrast, fertilizer (SP36) and farmer experience have no significant effect as indicated by t-counted of the SP-36 (0.238)<t-table (2.499) and t-counted the farming experience (1.8538)<t-table (2.478) leading to that the H0 of these factors is accepted Key Words: People plantation and Production of rubber.

Abstract

The study aimed to find plant spacing for better growth and yield of wetland rice crops under direct seeded planting system.  The study was arranged in a Randomized Block design with two factors i.e. two different spatial plantings and three kinds of Jajar Legowo patterns.  The plant spacing of 25 cm  x 25 cm with Jajar Legowo pattern of  2:1 produced highest grain yield (8.21 ton ha-1) followed by the plant spacing of 20cm x 20cm with Jajar Legowo pattern of 3:1 (7.21 ton ha-1).  Jajar Legowo pattern of 3:1 resulted in better plant height (74.80cm), similarly plant spacing of 25cm x 25 cm also had same plant height, more tiller number (30.69) and panicles per clump, longer panicle length and more grain number. Key Words: Jajar Legowo, Plant spacing, and Rice.

Abstract

Cocoa pod disease (BBK) caused by the fungus Phytophthora palmivora is one of the prime diseases that can affect cocoa production systems in the world . This disease can cause yield losses of up to 90% , especially in the rainy season and the dry season. Objective of the research is to determine the ability of inhibitory fungus A. niger in various carriesr and storage time against Phytophtora palmivora cause rotten disease of cocoa. Result of the research is to control the disease in cacao plants. This is an experimental research designed by using Random Complete Design with 2 factorials, carries and  storage period with 3 remedials, factor 1: (P0 = control), (P1 = white glutinous rice flour + cassava starch), (P2 = Cassava starch), (P3 = white glutinous rice flour + sweet corn flour), (P4 = white glutinous rice flour), (P5 = ripe coconut flour). Factor 2: (A1 = 1 week storage period), (A2 = 2 weeks storage period), (A3 = 3 weeks storage period), (A4 = 4 weeks storage period). Result of the research proved that the carrier of white glutinous rice flour + sweet corn flour (P3) and ripe coconut flour (P5) and in A3 storage period (week-3) is more effective to inhibiting P. palmivora growth, therefore can be used as a carrier to support A. niger fungus growth. Key Words : Aspergillus niger, cacao, carrier.
