Farmers’ Perception to The Role of Extension Workers on Kaligesing Goat Farm Management in Kaligesing, Purworejo

Abstract. The aims of this research were to describe the characteristics of Kaligesing goat farmers; to analyze the farmers’ perceptions on the role of extension workers as conduit of information, as mentors, organizers and dynamic factor, technicians and liaisons; to discover the relationship between the farmers’ characteristics with farmers’ perceptions; and to investigate the relationship between farmers’ perceptions to goat maintenance management. The respondents were goat farmers in Kaligesing, Purworejo, Central Java Province. Data were obtained from questionnaire survey method. Determining location, the research applied combination of stratified sampling method with purposive random sampling. Total respondents were 159 farmers with nine farmer groups as samples. Analysis was subject to Spearman Rank, resulting that age, education level and farming experience were not significant to the farmers’ perceptions to the role of extension workers, but the ownership of livestock had a very significant relationship with a correlation coefficient of 0.240, group classes had also very significant relationship with a correlation coefficient of 0.414, and frequency of meeting with extension workers have a significant relationships with a correlation coefficient of 0.202. Farmers’ perceptions to the role of extension workers had very significant relationships to the maintenance management with a correlation coefficient of 0.393. Key words : farmers’ characteristics, farmers’ perceptions, Kaligesing goat, role of extension workers Abstrak. Penelitian ini bertujuan untuk mengetahui karakteristik peternak, persepsi peternak terhadap peran penyuluh, hubungan antara karakteristik peternak dengan persepsi, dan hubungan antara persepsi peternak dengan manajemen pemeliharaan. Responden penelitian adalah peternak Kambing Kaligesing di Kecamatan Kaligesing Kabupaten Purworejo Jawa Tengah dengan metode penelitian survei kuesioner. Penentuan lokasi penelitian dengan kombinasi cara stratified sampling dan purposive random sampling. Jumlah kelompok tani sebagai sampel penelitian sebanyak sembilan kelompok dan jumlah total responden sebanyak 159 peternak. Analisis Rank Spearman digunakan untuk analisis data.  Hasil analisis menunjukkan  bahwa umur, tingkat pendidikan dan lama beternak tidak secara nyata memiliki hubungan dengan persepsi peternak terhadap peran penyuluh, sedangkan kepemilikan ternak memiliki hubungan sangat nyata (P<0,01) dengan nilai koefisien korelasi 0,240. Kelas kelompok memiliki hubungan sangat nyata (P<0,01) dengan nilai koefisien korelasi 0,414 dan frekuensi bertemu penyuluh memiliki hubungan nyata (P<0,05) dengan nilai koefisien korelasi 0,202. Persepsi peternak terhadap peran penyuluh memiliki hubungan sangat nyata (P<0,01) terhadap manajemen pemeliharaan dengan nilai koefisien korelasi 0,393Kata kunci:  karakteristik peternak, persepsi peternak, kambing Kaligesing, peran penyuluh

The effects of aquaculture on farm household economy: a case study in Omon District, Cantho Province, Vietnam

A study of the farming systems in the Mekong River Delta (Vietnam) indicate that fish culture brings to the household a higher level of net farm income and family labor use. In general, adoption of fish culture is strongly affected by: (1) decline of wildfish; (2) location of the farm; (3) farm size per person and available water bodies within the farm; (4) income of farm, excluding income from fish; (5) guidance from agricultural extension workers; (6) policies of local government on the development of agriculture including aquaculture.

Hardpan and maize root distribution under conservation and conventional tillage in Agro-Ecological Zone IIA, Zambia

Hardpans (plough/hoe pans) are commonly believed to restrict plant root growth and crop yields under conventional small-scale agriculture in sub-Saharan Africa. This study questions the notion of widespread hardpans in Zambia and their remedy under conservation tillage. Soil penetration resistance was measured in 8x12 grids, covering 80 cm wide and 60 cm deep profiles in 32 soil pits. Large and fine maize roots were counted in 8x6 grids. Soil samples from mid-rows were analysed for pH, exchangeable H+, exchangeable Al3+, cation exchange capacity, total N and extractable P (Bray 1) at six depths from 0-10 to 50-60 cm. Cultivation-induced hardpans were not detected. Soils under conservation tillage were more compact at 5 cm depth than soils under conventional tillage. No differences in root distributions between conservation and conventional tillage were found. Maize ( Zea mays L. ) roots were largely confined to a relatively small soil volume of about 30 cm x 30 cm x 30 cm. Root growth appeared to be restricted by a combination of low concentrations of N and P. Soil acidity and Al saturation appeared to play a minor role in root distribution. L-shaped taproots in soils under manual tillage reported earlier were not necessarily due to hardpans, but may rather be caused by temporarily dry, impenetrable subsoils early in the rain season. There is no scientific basis for the recommendation given to farmers by agricultural extension workers to “break the hardpan” in fields under manual or animal tillage in the study areas.
