Effect of Spraying With Bread Yeast Suspension and The Addition of NPK+(TE) on The Chemical Content of The Leaves of Tamarind Young Plants (Tamarindus indica L.)

Abstract

Abstract The experiment was carried out during the spring season from 1/3/2019 to 1/9/2019, to study the effect of foliar spraying with a suspension of bread yeast at concentrations 0.0, 2.5, 5.0 and 7.5 g.L-1, and the addition of the compound chemical fertilizer NPK+Trace Elements(TE)20-20-20 for soil with three levels (0.0, 0.5 and 1.0 g.plant-1 ) and their interactions in the chemical content of the leaves of two years old tamarind young plants. The research was carried out as a factorial experiment (4*3) according to the randomized complete block design (RCBD) with three replications. The indicators of the study showed that the foliar spraying with bread yeast suspension led to an improvement in most of the studied traits of tamarind young plants and the foliar spraying treatment with a concentration of 7.5 g.L-1 excelled in achieving the best results in comparison with the control treatment of nitrogen, phosphorous, potassium and protein content in the tamarind young plants leaves. Total chlorophyll and carotene, yeast did not have any significant effect in any of the concentrations in the experiment. The compound chemical fertilizer NPK+Trace Elements improved all the studied characteristics of tamarind young plants, and the treatment at the level 0.5 g.plant-1. While the concentration of one g.plant-1was superior in recording a significant increase of potassium concentration in the leaves. Whereas, the interaction between foliar spraying with bread yeast suspension and the addition of the neutral chemical fertilizer NPK+Trace Elements showed a significant effect in most of the studied traits, where the treatment was superior to 7.5 g.L-1 yeast and 0.5 g.plant-1 neutral fertilizer in recording the highest content in leaves of element N andprotein in the leaves, while the treatment recorded 7.5 g.L-' yeast and 0g.plant-1 neutral fertilizer was superior in the percentage of phosphorous, while the concentrations7.5 g.L-1 yeast and lg.plant-1. Neutral fertilizer were superior in percentage of Potassium in the leaves of tamarind young plants achieved a concentration of 0.0 g.L-1 yeast and 0.5g.plant-1 neutral fertilizer an outperformance in the leaf content of total chlorophyllwhile the treatment recorded 5 g.L-1 yeast and 0 g.plant-1 neutral fertilizer was superior in the percentage of carotene.
