Effect of concentration and p]spraying date of thiamine on growth and yield of two cultivars of mung bean

Abstract EN

A field experiment was conducted during the spring and autumn season for 2019.

In a private farm in Al-Mussaib project area, north of Babylon province, with the aim of studying the effect of thiamine concentrations and dates on the growth and yield of two cultivars of Mung bean.

The experiment was conducted according to the arrangement of split split plots and distributed the treatments using the Randomized complete block design( R.

C.

B.

D) with three replicates, The cultivars(local and Uzbekistan) obtained from local markets represented the main plots.

As for the secondary plates, the three spraying stages (a stage after 30 days of emergence, a stage after 45 days of emergence and a stage after 60 days of emergence) and the sub-plots included thiamine concentrations and were as follows (spraying with distilled water only, 100 mg.

L-1, 200 mg.

L-1 and 300 mg.

L-1 ).

The results of the statistical analysis of the data were as follows: The local cultivar excelled the Uzbekistan cultivar in the number of pods, the pod length for the autumn season, the seed yield, the protein percentage, the Uzbekistan cultivar excelled in the weight of 1, 000 seeds.

The second date excelled the number of pods, the number of seeds, the weight of 1000 seeds, the seeds yield, the third date excelled in the protein percentage.

The fourth concentration 300 ppm excelled in pod length, the number of seeds, protein ratio, second concentration exceeded in a number of pods, the weight of 1000 seeds, seed yield.

The interaction between the cultivars and the dates led to a significant effect on the studied traits.

The combination the local cultivars with the second date excelled in the number of pods, the number of seeds, while the combination between the local cultivar with the third date excelled in the protein percentage of the autumn season, the combination the Uzbekistan cultivar with the second date excelled in Number of seeds, weight 1000 seeds.

Significant interaction appeared between the cultivars and concentrations in the studied traits, where the combination the local cultivar with the fourth concentration 300 mg.

L-1 excelled in the pod length, number of seeds, and the protein percentage of the spring season, The interaction between the local cultivars with the second concentration 100 ppm excelled in the number of pods, seed yield, for the autumn season, The interaction between the Uzbekistan cultivar with the fourth concentration 300 ppm excelled in the pod length, the combination the Uzbekistan cultivar with the first concentration 100 ppm excelled in the weight of 1000 seeds.

The bi-interaction between the dates and the concentrations significantly in the studied traits resulted in the combination the second date with the fourth concentration of 300 ppm excelled in the number of seeds.

Pod, The combination between the second date with the first concentration 100 ppm excelled in the number of pods, the weight of 1000 seeds, seed yield, for the spring season, the combination the third date with the fourth concentration of 300 ppm excelled in the protein percentage for the spring season.

The triple interaction between the cultivars, dates and concentrations was significant.

The triple treatment between the local cultivar with the second date and the second concentration100 ppm excelled in the number of pods.

plant for the autumn season, the triple treatment between the local cultivar, the second date with a fourth concentration of 300 ppm excelled in the number of seeds.

Pod, The triple interaction between the local cultivar with the third date with the fourth concentration of 300 ppm excelled in the protein percentage for the spring season, the combination the Uzbekistan cultivar with the second date with the fourth concentration 100 ppm excelled in the weight of 1000 seeds for the autumn season, the combination the Uzbekistan cultivar with the second date with the fourth concentration 300 ppm excelled in the number of seeds.
