Contribution of Morphological Variables in Garlic Bulb Yield

Abstract

<jats:p>The objective of this work was to investigate the direct and indirect relationships of morphological variables on garlic bulb yield. The primary components of garlic bulb yield, including clove mass, number of cloves per bulb, and bulb diameter and bulb length, are the variables that affect garlic bulb yield directly. Leaf length and growth of a secondary bulb had a negative correlation to garlic bulb yield. Growth of a secondary bulb also had a negative correlation with the number of cloves per bulb and root dry mass. Irrigation with the deficit, applied at the stage of bulb formation, had a positive correlation with garlic yield and a slightly negative correlation with total plant mass, bulb length, and secondary bulb growth.</jats:p>

Contribution of Soil Attributes and Morphological Variables to Yield of Irrigated Garlic

“…Determination coefficients above 0.70 are considered high. Authors such as Silva et al, 2017b, Teodoro et al, 2015, Oliveira et al, 2018, and Oliveira et al, 2020 have also found coefficients of determination higher than 0.70. 5.…”

“…Thus, in the presence of multicollinearity, all variables evaluated in the path analysis can be included, but a constant (k = 0.05) must be added to the diagonal of correlation matrix to solve this problem. The method used by Oliveira et al, 2020 for a garlic trail analysis study.…”

“…Path analysis has been used by many authors in several crops with economic importance, such as cotton (Farias et al, 2016), sorghum (Silva et al, 2017a), sugarcane (Silva et al, 2017b), soybeans (Teodoro et al, 2015), beans (Oliveira et al, 2018), and garlic (Oliveira et al, 2020). This study aimed to investigate relationships between the soil attributes that most affect garlic yield, which can be useful to choose a new area for the growing of this vegetable.…”

Efeito da frequência de irrigação e fósforo nas características biométricas do milho

“…Tem sido relatada a existência de relação direta entre a demanda hídrica e teores de nutrientes no solo (Oliveira et al, 2020b). Neste sentido, o estudo da influência da frequência de irrigação e doses de fósforo, pode fornecer subsídios para escolha da melhor forma de condução da lavoura e, consequentemente, contribuir para melhorar a eficiência na absorção deste nutriente.…”
