Low soil N nutrient content is a limiting factor in efforts to increase the maize production. Hybrid maize varieties are generally very responsive to fertilization and have high yields in optimal environments in contrast to abiotic stress conditions such as low nitrogen. Therefore, it is necessary to develop hybrid maize with low N tolerance by genotyping at low N fertilization conditions. This research aims to obtain hybrid maize genotypes tolerant to low nitrogen with high production and to determine characters that have high heritability values. The research was carried out in the Experimental Farm of the Cereals Plant Research Institute, Bajeng Subdistrict, Gowa Regency, South Sulawesi Province. The research was arranged in a Split Plot Design with the main plot is dose of nitrogen (0 kg N/ha, 100 kg N/ha, 200 kg N/ha) while subplots were hybrid maize genotypes consisted of 12 genotypes and 3 comparative varieties (Nasa 29, Bisi 18, and Jakarin 1). The results show that the hybrid genotype tolerant to low nitrogen with high production were AVLN 83-2 x AVLN 124-9 genotypes in the treatment without nitrogen fertilization and AVLN 83-2 x AVLN 32-8, AVLN 83-2 x AVLN 124-4, AVLN 83-2 x AVLN 124-9, AVLN 83-2 x AVLN 100-1, AVLN 122-2 x AVLN 124-9, AVLN 122-2 x AVLN 100-1, and AVLN 118-7 x AVLN 124-9 at a nitrogen dose of 100 kg N/ha. Characters with high heritability values were peeled cobs weight, cobs diameter, cobs length, 1000 seeds weight, and productivity.
The research used qualitative methods with a descriptive type to describe a case study that happened in Sailong Village. Data sampling used a purposive sampling technique, while data collection included in-depth interviews, direct observation, and documentation.
Based on the results of this study, labeling the status of young widows that occurs is not necessarily interpreted as having a negative (bad) connotation. A bad “label” does not indicate that the woman cannot prove that the label is wrong and is only a stereotype, stigma, and prejudice that does not apply to every individual. Therefore, the way to overcome it is by maintaining attitudes and behavior to always be good in the broader community. Furthermore, sometimes the community defines the status of widows in general based on what they saw or encountered based on experience. When seeing or meeting a widow who is not good, the definition becomes bad.
ABSTRAK
Penelitian menggunakan metode kualitatif dengan tipe deskriptif untuk menggambarkan studi kasus yang terjadi di Desa Sailong tersebut. Adapun teknik pengambilan sampel menggunakan teknik purposive sampling sedangkan teknik pengumpulan data yang digunakan adalah wawancara mendalam, observasi langsung dan dokumentasi.
Hasil penelitian ini, pelabelan yang terjadi terhadap status janda muda, sebenarnya belum tentu diartikan sebagai perempuan berkonotasi negatif (buruk). Berkaitan mengenai “Label” yang buruk bukan berarti perempuan tersebut tidak mampu membuktikan bahwa label tersebut adalah salah dan hanya sebuah stereotype, stigma dan Prejudice yang tidak berlaku untuk semua orang. Sehingga untuk mengatasinya dengan menjaga sikap dan perilaku untuk senantiasa bersikap baik di masyarakat luas sedangkan masyarakat kadang dalam mendefinisikan status janda secara umum seperti yang pernah mereka lihat atau temui berdasarkan pengalaman. Ketika melihat atau menemui seorang janda yang bersikap tidak baik, maka pendefisiniannya buruk.
The research was aimed to obtain male and female rows ratio and best pruning technique towards SINHAS 1 maize production. This research was conducted in Experimental Farm Faculty of Agriculture, Hasanuddin University, Tamalanrea District, Makassar, South Sulawesi with elevation of 22,4 meters above the sea level throughout May – August 2020. The experiment was carried out in the form of Split Plot Design with male-female row ratio as main plot, which consisted of three levels: 1:2 ratio, 1:3 ratio, and 1:4 ratio. Sub plot was pruning techniques: no pruning, male parent pruning and leaf pruning under the cob of female parent. The result showed that the favorable male-female row ratio towards SINHAS 1 maize production was 1:4 ratio. Male parent pruning was the best pruning technique for SINHAS 1 maize production. The interaction between male-female ratio and best pruning technique was 1:3 male-female ratio with male parent pruning technique. Characters that showed positively direct significance towards productivity were cob diameter, cob length, and number of seed rows per cob
