Modelos de crescimento para cultivares de capim-sudão em épocas de semeadura
Pezzini, Rafael VieiraCoordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES; The objectives of this work were to fit the Gompertz and Logistic models to describe the growth of morphological and productive traits as a function of accumulated thermal sum and accumulated solar radiation, comparing the adjustments and indicating the best to describe the growth of two sudangrass cultivars in four sowing seasons. Eight unifo...
Models for leaf area estimation in dwarf pigeon pea by leaf dimensions
Wartha, Cleiton Antonio; Pezzini, Rafael Vieira; Cargnelutti Filho, Alberto; Alves, Bruna Mendonça; Follmann, Diego Nicolau; Kleinpaul, Jéssica AndiaraThis study aims to determine the most suitable model to estimate the leaf area of dwarf pigeon pea in function of the leaf central leaflet dimension. Six samplings of 200 leaves were performed in the first experiment, at 36, 42, 50, 56, 64, and 72 days after emergence (DAE). In the second experiment, seven samplings of 200 leaves were performed at 29, 36, 43, 49, 57, 65, and 70 DAE, totaling 2600 leaves. The le...

Wartha, Cleiton Antonio; Cargnelutti Filho, Alberto; Lavezo, André; Bem, Cláudia Marques de; Carini, Fernanda; Schabarum, Denison EsequielThe aim of this study was to determine the optimum plot size to evaluate the fresh matter of aerial part of dwarf pigeon pea (Cajanus cajan (L.) Millsp), cultivar IAPAR 43 (Aratã), in scenarios formed by combinations of numbers of treatments, number of replications, and precision levels. The fresh matter of aerial part was weighed on basic experimental units of 1 m × 1 m in three uniformity trials with size of ...
