Abstract

This study was conducted in vegetable field of Horticulture Department /college of Agric. and forestry / Mosul University during the winter season of 2017-2018, to study the effect of two methods of planting (plots and furrows), and spraying with different concentration levels: 0, 3, and 6 ml.l-1 of nutritious organic solution, Tecamin Max, on the growth and production of two varieties of radish, red Celesta, and black Rudi.The results have showed a significant of furrows method as compared to the plot method when it comes to the majority of the studied characteristic, including: leaves area, the length and diameter of the root, the dry weight of the roots, the weight of the single plant, and the total yield. As for spraying with the nutritious organic solution, Tecamin Max, with 3ml.l-1 concentration levels, it showed a significant advantage regarding comparison in the length and diameter of root. The black varieties was advantageous when it came to dry root weight, while the red was advantageous in the weight of the single plant, the total yield, and the root length. Dual and triple interaction have also matched single interaction of each factor, with the triple interaction of furrow planting, while spraying with 3ml.l-1 of Tecamin Max for the red varieties providing the highest ratio of the single plant of 171.6g, and the highest total of roots of 22.88 t.ha-1.

Highlights

Radish (Raphanus sativus L) belongs to the Brassicaceae family
Results of Tables (8 and 9) show a significant advantage of furrow planting over plot planting gave heighest values of length and diameter of the root, with an increase of 15.9 and 23.6%, while treating with low concentration Tecamin Max of 3ml.l-1 have resulted in the highest values of both characteristic, and had no significant difference compared with high concentration spraying of 6ml.l-1 with an increase rate of 7.58 and 6.20% for both characteristic consecutively
As for triple interaction regarding the three studied factors results were similar to the singular and dual interaction, where the furrow plants of the red varities which were sprayed with low concentration Tecamin Max resulted in the highest values regarding length and diameter of roots 8.65 and 7.06 cm consecutively, while plot plants of the red varities of radish that are untreated with the nutritious Tecamin Max solution with the least length being 4.76, while plot black varities plants untreated with nutritious Tecamin Max solution registered the least root diameter of 3.63 cm

Summary

Introduction

Radish (Raphanus sativus L) belongs to the Brassicaceae family. It is one of the stored root winter plants which are common in Iraq, and is farmed for the leafs and roots which are eaten fresh, with the roots of some of its’ varieties cooked (Hasan, 2003). Using amino-acids is one of the modern techniques which provide good agricultural produce (Cerdana et al 2009), due to its’ positive effects on plenty of physiological and biological operations within the plant, since plants do need to continue growing and producing (Hounsome et al 2008). It helps plants in responding to physiological circumstances of the environment due to its’ role in stimulating the work and production on many organic compounds (Ibrahim et al 2010).
