Corn is the main crop commodity in terms of business aspects and the use of the results as raw material for food and animal feed. In Takalar district there are several patterns of corn marketing channels. This study aims to determine the pattern of corn marketing channels and the efficiency of corn marketing using margin analysis and farmers share methods. The analysis shows that there are 2 patterns of marketing channels, the first channel (farmers - village collectors - sub-district collectors - large traders - end consumers) with a total margin of Rp. 800 / kg and farmers share 78.9%, while in the second channel pattern (farmers - village collectors - large traders - end consumers) get a total margin of Rp. 750 / kg and farmers share 80.3%. The difference in margins and farmers share in the pattern of the first channel with the second channel shows that the longer the market chain, the greater the total marketing margin and the smaller the value of farmers share. For stakeholders, the results of this research can be information material for more efficient implementation of corn marketing.
Technology is one factor in increasing agricultural production capacity. The use of new technologies will increase the use of inputs, making it possible to achieve production and farm efficiency. The jajar legowo (double row) system is a technological engineering to obtain a plant population of more than 160,000 per hectare. The implementation of Jajar Legowo in addition to increasing the cropping population, is also able to increase the smooth circulation of sunlight and air around the pingir plants so that the plants can photosynthesize better. Assistance in the application of engineering technology for the legowo row 2: 1 system was carried out in Panrannuangku sub-district, Polut sub-district, Takalar district. The technology engineering of the legowo row 2: 1 system is supported by other technologies that are applied through pilot farming models (demfarm) at strategic locations in the development area that have fairly good access, which can be seen by the community in the assisted area. The selection of the demfarm location is determined together with the farmer groups, field officers / PLL and stakeholders involved so that it can be ascertained that the pilot farming model can represent the conditions of the development area to be built. The results of the assistance in the area of rice farming in irrigated rice fields in Takalar Regency, South Sulawesi, show that the development of the rice crop area has a large enough opportunity to be developed with the support of legowo row 2: 1 technology engineering and institutional innovation. The results of the assistance for the paddy farming area with a 2: 1 legowo row technology engineering planting system in the irrigated rice fields of Takalar Regency also provide understanding to the relevant agencies starting from the planned mentoring model to the implementation stages. The rice technology demfarm with the legowo row system technology engineering 2: 1 showed an increase in yield from 4-5 tonnes per ha (local productivity) to 7-8 tonnes per ha.
Land management techniques in this study are grouped into a full tillage and no tillage practices. Full tillage which generally uses simple tools for heavy equipment is basically aimed at controlling weeds and loosening the soil so that aeration and soil infiltration capacity increases. This study aims to examine the effect of land preparation and land preparation on maize growth and maize production. This research was conducted at the location of farmers in Takalar Regency in the dry season. The effects of the planting system indicate that the system is without soil; plant height (240.6 cm), biomass in cobs (7.3 t / ha), straw weight (22.1 t / ha), cob length (16.6 cm) and corn production (10.1 t/ha ). OL Perfect Land technology results; plant height (239.2 cm), biomass on cob (6.7 t / ha), straw weight (19.1 t / ha), cob length (16.4 cm) and corn production (9.8 t /ha ). The effect of varieties shows that Bima-2 and Bima-3 varieties are higher in the growth and yield components of corn than other varieties. While the interaction effect shows that the Bima-2 variety with the No Grounding planting system gives straw weight (27.6 t / ha) and corn production (13.5 t / ha) higher than the same variety as the fully Soil Cultivation system, namely weight straw (26.6 t / ha) and corn production (13.2 t / ha). The Gumarang variety in the Soil planting system gives a straw weight (18.2 t / ha) and dry shell corn production (7.9 t / ha) while the Perfect Earth planting system gives a straw weight (15.1 t / ha) and dry production shells corn (7.9 t / ha). t / ha) lowest among other interaction treatments. Potential yield of corn biomass is between 15-27 t / ha. The weight of straw produced from corn biomass is generally used as a source of animal feed consisting of stems, leaves and cob. The composition of corn biomass containing cellulose, hemicellulose, lignin, ash and extractives with their chemical composition, utilization of stems, leaves and cob for the fulfilment of nutritious livestock feed is very prospective.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
