CLYBIO CONCENTRATION ON GROWTH AND YIELD OF CABBAGE UNDER DIFFERENT COLORED SHADE NETS

Abstract

The experiment was conducted at the Horticulture farm of Sher-e-Bangla Agricultural University, Dhaka to evaluate the growth and yield of cabbage as influenced by two different factors such as factor-A: Colored shade nets viz. without a net (N 0 ), white net (N W ), pink net (N P ), and blue net (N B ), and factor B: Clybio concentration viz. no Clybio application (C 0 ), Clybio concentration at 1000-fold (C 1000 ), and Clybio concentration at 500-fold (C 500 ). The experiment was set up in Split Plot Design with three replications. Data on different growth, physiological and yield parameters were taken in which all the treatments showed significant variations. The use of white shade nets (Nw) provided with better head length (16.0 cm), head diameter (55.7cm), single head weight (1.1 kg), and yield of 45.8 t/ha in comparison to other nets or no net use. Alongside, the sole application of Clybio to cabbage as a 1000-fold liquid solution (C 1000 ) resulted in maximum single head weight (0.8 kg), and yield of 33.3 t/ha while the maximum head length (14.8 cm) was from 500-fold Clybio solution (C 500 ), and head diameter was statistically insignificant between C 1000 . Maximum yield per hectare (62.5 t) was found from N W C 1000 and minimum (20.8 t) was from N 0 C 0 . In consideration to the overall performances, white shade net (N W ) along with the application of 1000-fold Clybio solution (C 1000 ) has the potential for better cabbage production.
