The objective of this study was to evaluate eighteen genotypes of safflower and their absorption of macronutrients in an experiment conducted in the western region of the state of Paraná. The experiment was conducted under humid subtropical climate on Typic Hapludox soil with very clayey texture. The treatments were carried out in randomized blocks with four replications. The following traits were evaluated: shoot dry mass production, seed yield, shoot and seed macronutrient accumulation, and oil production. Data were submitted to analysis of variance and the means compared by Scott-Knott test at 5%. The mean seed yield was 4,531.8 kg ha -1 and the mean oil content was 26%. The descending order of safflower macronutrient uptake was N > K > Ca > P > Mg > S, in all genotypes, and macronutrient export was N > P > K > Mg > S > Ca. Mobility of macronutrients extracted from seeds was low for K and Ca, medium for Mg and S, and high for N and P. The genotypes with higher average yield were less efficient in their utilisation of nutrients.
As bacias hidrográficas possuem aspectos físicos influenciadores no seu comportamento hidrológico. Desta forma, este trabalho objetiva analisar a morfometria de um segmento da bacia hidrográfica do Rio Piquiri, localizada no município de Palotina. Em seguida, realizar o zoneamento climático para a região de estudo, com o intuito de definir a viabilidade para o cultivo de pinhão manso e a distância média de transporte (DMT) deste para as usinas de biodiesel do Paraná. A partir da análise dos dados foi possível concluir que a área corresponde a 378,506 km2, fator de forma 0,25, coeficiente de compacidade 1,10, índice de conformação 0,39, declividade média da área da bacia de 333,86 metros, declividade do curso d’água 0,00585 m.m-1 (S1), 0,00543 m.m-1 (S2) e 0,0047 m.m-1 (S3), densidade do curso d’água 0,00449 km e de drenagem 0,384 km/km2.Considerando-se as características desta área este trabalho conclui que o município estudado revela-se apto para o cultivo de pinhão manso em relação às necessidades térmicas e hídricas. E a DMT é mais favorável dentro do estado do Paraná são para as cidades de Céu Azul, Santa Helena e Tuneiras do Oeste, onde a distância total a ser percorrida não é maior que 250 Km.
