Tujuan dari analisis adalah untuk mengetahui pcubah bebas yang sangat mempengaruhi peubah yang tidak bebas, indeks mutu dan kadar nikotin daun, sehingga dapat mengurangi banyaknya pengamatan yang dilakukan. Data pengamatan agronomis yang meliputi : jumlah daun/pohon, luas daun ke-7, luas daun ke-15, bobot rajangan kering/ha, indeks mutu dan indeks tanaman diperoleh dari percobaan pemupukan tiga galur harapan tembakau Virginia di kebun percobaan Pekuwon Bojonegoro dari bulan Mei sampai dengan Oktober 2002. Hasil analisis lintas antara indeks tanaman dengan peubah bebas di atas menunjukkan bahwa indeks tanaman sangat ditentukan oleh bobot rajangan kering dengan koefisien lintas pm-1.03367 dan koefisien dcterminasi parsial 102%. Hubungan lintas bcrantai melalui pcubah rajangan kering dan indeks mutu menunjukkan bahwa luas daun kc-7 sangat mempengaruhi rajangan kering dengan koefisien lintas (p„i)- 0.85257 dan rajangan kering sangat mempengaruhi indeks tanaman dengan koefisien lintas (p,x,)= 0.95639, indeks mutu pengaruhnya terhadap indeks lanaman sangat kecil dengan koefisien lintas p,M = 0.12316. Analisis lintas antara kadar nikotin daun dengan ke lima peubah tidak baik (unfit) dengan koefisien sisa p„,= 0.6827 melebihi koefisien lintas yang lainnya. Dengan pentingnya peubah rajangan kering ini maka penjualan daun segar yang dilakukan oleh petani tidak dianjurkan.<br /><br />Kata kunci: Nicotiana tabacum, tembakau Virginia, analisis lintas, jumlah daun, luas daun, indeks tanaman, indeks mutu, kadar nikotin, bobot rajangan ABSTRACT Path analysis of agronomical characteristics on crops index and nicotine content of Virginia tobacco Bojonegoro The relationship between agronomical characteristics and crops index or leaf nicotine content has been studied by using path analysis. The purpose of this analysis was to determine the independent variables which most affected the dependent ones as crops index and leaf nicotine contain, so that it could reduce the number of independent variables. The agronomical characteristics consist of leaf number/plant, seventh and fiteenth leaf area, dried slice leaf/ha, grade index and crop index obtained from fetilizer experiment on three Virginia tobacco lines at Pekuwon Experimental Garden Bojonegoro, from May to October 2002. The results of this path analysis showed that crop index was strongly affected by dried slice leaf with path coeficient poi = 1.03367 and patial determination coefficient 102%. It was indicated that dried slice leaf was strongly affected by seventh leaf area with path coefficient p,n- 0.85257 and dried slice leaf strongly variable affected the crop index with path coeficient poi= 0.95639, while the grade index had little effect on crop index with path coefficient poi= 0.12316. The path analysis between leaf nicotine content and ive variables above was unfit with residual path coeficient pou= 0.6827, it was higher than each path coefficient of the orther variables. The dried slice leaf was the main independent variable affecting the crops index, so that selling of fresh tobacco leaves by farmers is not recomended.</p><p>Key words : Nicotiana tabacum, Virginia tobacco, path analysis, leaf number, leaf area, crop index, grade index, nicotine content, dried slice leaf</p>

Pig population in East Nusa Tenggara Province in 2019 was recorded at around 2 million pigs. In east Nusa Tenggara around 85% of the households raise at least 1 (one) pig per household. Pig farming industry has its own challenges and resistances, one of the challenge is the threat of infectious diseases such as Hog cholera disease. Hog cholera is a disease caused by virus and has become endemic in most of the area in East Nusa Tenggara with relatively high prevalence. In Kupang City the prevalence of HC in 2018 was recorded at around 20,5%. The aim of this study is to analyse the relationship of pig farmer characteristics with knowledge level, attitude and practice regarding HC controlling and eradication in Kota Raja Sub-distric Kupang City. In this study, data was obtained by questionnaire and interview of pig farmers which was done in Kota Raja Sub-distric from August until October 2018. Data was analyzed with descriptive statistic and KAP studi data was analyzed with path analysis to measure the relationship between observed characteristics and HC controlling practice. The result of this study shows that variable that has the stongest relationship to practice is level of education with path coefficient (r) of -0,438 (P 0,027), followed by attitude with path coefficient (r) of 0,233 (P 0,000), and then followed by knowledge with path coefficient (r) of 0,224 (P 0,008) and the weakest realationship to practice is farmers age with path coefficient (r) of -0,049 (P 0,016).

Path analysis depicted the strength of association of all independent variables under study on the grain yield. Thus, the study aimed at examining changes in associations and path analysis of yield related traits to yield in post-monsoon and monsoon season. A total of 14 maizegenotypes were evaluated in two growing seasons at the Maize and other Cereal Crops Research Section, Department of Agricultural Research (DAR), Yezin, Nay Pyi Taw, Myanmar. Genotypic correlation and path coefficient analyses were carried out to examine the relationship among the traits under both environments. Yield was positively correlated with ear length, row length, ear diameter, rows per ear, kernels per row, shelling percent and 1000 seed weight but had a negative correlation with days to tasseling and days to silking in both growing seasons with different magnitudes. These traits can be used as the main criteria for grain yield improvement of maize yield in the respective growing seasons. Some traits showed similar direct effects in both growing seasons, however,the link between direct and indirect effects on grain yield depends on respective growing season.

Abstract Correlation and path coefficient analysis were worked out for ten morphological traits in 30 three-way crosses of maize. Phenotypic and genotypic correlation analysis indicated that ear length; row numbers per ear, grain numbers per row, leaf area and leaves numbers had a positive significant correlation with grain yield per plant. Further partitioning of correlation coefficients into direct and indirect effects showed that traits days to silking, row numbers per row and leaves numbers had a positive direct effect on grain yield per plant. The traits ear length, grain numbers per row and leaf area had a maximum total effect on grain yield. Furthermore, PCA analysis has gave interested results and it supported the results of correlation and path analysis. The correlation and path analysis obviously indicated that direct selection based on these attributes may be useful in raising grain yield in maize.

Lincat is a disease caused by a complex<br />invasion of three pathogens i.e. Meloidogyne spp. (root-knot nematode),<br />Ralstonia solanacearum (bacteria) and Phytophthora nicotianae (fungus).<br />Hybridization between variety Sindoro 1 (moderately resistant to R.<br />solanacearum but susceptible to Meloidogyne spp. and highly susceptible<br />to P. nicotianae) and virginia tobacco (resistant to these three pathogens)<br />has resulted in six lines. These lines were planted in three locations for 3<br />years and were evaluated for their yield, grade index, crop index, and<br />resistance intensity to these three pathogens, using randomized block<br />design with 3 replications. Two promising lines were resulted from this<br />evaluation i.e. (1) Line A, that has productivity of tobacco sliced : 0.880<br />ton per hectare, grade index: 40.28 crop index: 35.47 and nicotine content:<br />5.52%. In comparison to standard variety, the productivity, grade index,<br />and crop index of this line increased of 48.08%, 4.87%, and 53.73%,<br />respectively, and nicotine content decreased of 15.06%. Moreover, this<br />line is moderately resistant to R. solanacearum and tolerant to<br />Meloidogyne spp. (2) Line E, that has productivity of tobacco sliced:<br />0.869 ton per hectare, grade index: 36.01 crop index: 31.87 and nicotine<br />content: 6.00%. This line also has increase productivity, and crop index of<br />46.23% 38.12%, respectively, and has decrease grade index and nicotine<br />content of 6.25% and 2.56%, respectively compared to standard variety.<br />This line is moderately resistant to R. solanacearum and tolerant to<br />Meloidogyne spp.<br />Key words : Tobacco, Nicotiana tabacum, Temanggung, promising line,<br />Ralstonia solanacearum, Meloidogyne spp., Phytophthora<br />nicotianae, lincat land, East Jav
