The Effect of Adding Whey and Spraying with Silicone on the Chemical of Chinese Cabbage Plant Brassica campestris var. Pekinensis

Abstract

The experiment was conducted in the fields of horticulture and Garden Engineering at the College of Agriculture - University of Kerbala for the agricultural season 2022-2023 with the aim of knowing the effect of spraying with silicon in the form of potassium silicate (K2Sio3) and adding the by-product (whey) in improving the growth indicators of the Chinese Cabbage plant. The experiment included 16 treatments that included four concentrations of silicon (0.1.2.3) ml L-1 and four concentrations of whey by-product (0.8.16.24) L ha-1 and were in three batches between one batch and another 10 days. It was carried out as a factorial experiment with two factors according to the randomized block design and with three replications, and the least significant difference test (l.s.d) was used to compare the means at the probability level of 0.05. Silicon spraying treatment led to a significant increase in all yield traits, as the concentration of 3 ml L-1 was significantly superior in each of Nitrogen percentage, phosphorus percentage, potassium percentage and ascorbic acid. As for the treatment of whey addition, the concentration of 24 liters ha-1 was significantly higher in Nitrogen percentage, phosphorus percentage, potassium percentage and ascorbic acid. 2.547 ‘0.316‘ 1.403‘ 64.61 respectively. The bilateral interaction between the two experimental factors showed significant superiority in all the traits under experiment.
