Root growth of citrus rootstocks (sour orange and Volcamriana) affected by foliar nutrition with coconut liquid and dry yeast extract

Abstract

This study aimed to improve the root growth indicators of the citrus rootstock (Volcamriana and sour citrus) by spraying them with coconut liquid extract and yeast extract. The experiment was carried out using the Randomised complete blocks design (R.C.B.D) as a factorial experiment with three factors: the citrus rootstock (sour orange and lemon Volcamriana) and the extract of coconut liquid with three concentrations (200, 100, 0) ml. L-1 and dry baking yeast extract in three concentrations (0(8, 4, g.L-1 with three replicates. At the end of June of 2023 the measurements were taken and the results were analyzed according to the statistical design used, and the averages were compared according to the selection of the least significant difference and at the level of probability 0.05, and the most important results reached: rootstock Volcamriana excelled in the studied root qualities (root length, root diameter, root size , dry weight of root group) while the treatment of coconut liquid 200 ml L-1 and the treatment of dry yeast extract at a concentration of 8 g L-1 achieved significant superiority for the studied qualities (root length , root diameter , root size , dry weight of the root group) By giving it the highest averages. The treatment of the binary interaction between )rootstock Volca mriana + coconut liquid 200 ml L-1) and treatment (rootstock Volca mriana + dry baking yeast extract at a concentration of 8 g L-1) and treatment (coconut liquid 200 m. L-1 + dry baking yeast extract at a concentration of 8 g L-1 are the highest averages in the root qualities studied.The triple overlap treatment gave) rootstock Volca mriana + coconut liquid 200 ml L- + 1dry baking yeast extract at a concentration of 8 g L-1 significantly excelled in the majority of the studied growth qualities) root length , root diameter, root size, dry weight of the root group (.
