The objective of this experiment was to study the response of rice genotypes to nitrogen under low temperature stress condition. This experiment was done at Sesean rural area, Tana Toraja Regency, South Sulawesi, 1500 m above sea level with mean temperature 18oC. Experiment was designed in Completely Randomized Block Design with two factors. The first factor comprised of 3 levels of Nitrogen dosage (0, 50, and 100 kg N / ha) and the second factor was cultivar i.e. Pulu' Mandoti, Pinjan, Lambau, Fatmawati, Sintanur and Gilirang. The results showed that at low temperature stress condition, nitrogen, cultivar and their interaction gave significant effect on percentage of pollen fertility, percentage of filled spikelet and weight of filled grain per spikelet, while interaction between nitrogen and cultivar did not significantly affect the flag leaf length and flowering date. Rice yield decreased with increasing N levels under low temperature stress condition. There were significant positive correlations between growth components (percentage of pollen fertility, flag leaf length and flowering date) and yield components (number of tiller and grain per panicle and weight of 1000 grain). Key words: low temperature stress, nitrogen fertilizer, rice, highland, pollen fertility

One of the definite successful of rice breeding programs for increasing yield and tolerance to environmental stress condition is selection method. Selection method will be effectively if it is supported by a perfect knowledge of genetics character inheritance. The objectives of this study is to investigate the information of inheritance pattern adapted of rice towards low temperature stress condition. The experiment was conducted in both Sesean rural area, Toraja regency, South Sulawesi on 1500 m above sea levels, an mean temperature 15 o C, type of soil is Podzolic and at Bogor Agriculture Institute. This experiment is done in January 2006 until July 2007. The result showed that tolerance parental grew well and higher yield than sensitive parental. There were no significant differences between F1 and F1 reciprocal for all characters. Tolerance parental is more superior than sensitive parental in all characters have been tested. Mean of F1 generation is in between tolerance parental and sensitive parental. BCP1 has spheres wider than parentals and F1 generation, but BCP2 smaller than parentals and F1 generation. F2 generation is spheres wider than the average of both parentals. The m [d] [h] genetic model is the most suitable for all characters. Except, date of flowering and weight of filled rice where appropriate models is m [d] [h] [l]. Broad sense and narrow sense heritability is range between low to high. Based on the degree of dominant, additive effect is higher than dominant effect. The negative F value reached on date of flowering and fur lenght; and others characters, F value is positive.

Ubi jalar atau ketela rambat (Ipomoea batatas. L) merupakan salah satu bahan makanan yang mempunyai daya adaptasi tinggi pada berbagai tekstur dan struktur tanah, serta dapat tumbuh dengan baik di dataran rendah sampai dataran tinggi. Faktor genetik dan lingkungan juga berperan penting dalam produksi ubi jalar. Pembalikan batang tanaman ubi jalar dapat meningkatkan produksi dibandingkan tanpa pembalikan batang. Usaha–usaha lain untuk menunjang peningkatan produksi adalah pemupukan terutama pupuk SP-36. Penelitian ini bertujuan untuk mengetahui pengaruh pembalikan batang tanaman dan pupuk SP-36 terhadap pertumbuhan dan produksi ubi jalar. Percobaan dilaksanakan di kebun percobaan kampus II UKI Toraja, Kakondongan, Kecamatan Rantepao, Kabupaten Toraja Utara. Penelitian ini disusun berdasarkan RAK-faktorial yang terdiri atas 2 faktor yaitu frekuensi pembalikan batang dan dosis pupuk SP-36. Hasil percobaan menunjukkan bahwa pembalikan batang satu kali berpengaruh baik terhadap pertumbuhan dan hasil tanaman ubi jalar. Dosis SP-36 100 kg/ha berpengaruh baik terhadap komponen pertumbuhan dan hasil tanaman. Interaksi pembalikan batang satu kali dan pupuk SP-36 100 kg/ha berpengaruh baik terhadap indeks luas daun. Karakter laju pertumbuhan tanaman, jumlah umbi dan diameter umbi berperan penting dalam meningkatkan produksi tanaman ubi jalar.
