Effect of Potassium Humate and Spraying With Boron on the Yield and Its Components of Sesame Crop

Abstract

Abstract The impact of ground addition of potassium humate and boron spraying on sesame indicators, yield, and its components was investigated in a field experiment at the Research Station of the Field Crops Department of the College of Agriculture - Tikrit University 2021. The experiment was carried out using a randomized complete block design (RCBD) using a factorial experiment consisting of two components, the first of which was the addition of potassium humate and the second of which was the spraying of boron. During the first week of June 2021, seeds were planted in soil that had been amended with potassium humate at five different concentrations: 0, 3.6, 7.2, 10.8, and 14.4 g.l-1. A randomized full block design was used to statistically assess the data gathered from spraying three different amounts of boron (0, 100, and 200) g.l-1 prior to the onset of flowering. Here is a rundown of the findings: The number of capsules per plant treated with potassium humate (H3) was the highest (89.111 capsule.plant-1), and the total yield was also much higher (compared to other treatments) (3.427 kg.ha-1). Both the capsule length (2.573 cm) and the individual yield (15.673 g) were significantly higher in plants that were subjected to a boron (B3) spraying treatment. For the features of the number of seeds per capsule (71,333 seeds.capsule-1) and the weight of one thousand seeds, the interaction combination (H5B3) yielded the greatest significant value (4.491 g).
