Effect of zeolit, hydrogel and vermicompost on some morphological traits in marigold (Calendula officinalis L.)

With respect to the ever icreasing trend in the applicability of zeolite, superabsorbent polymer in agriculture especialy in arid and semiarid region, and vermicompost in producing healthy crop, a pot experiment was conducted in factorial based on a randomized complete block design with three replications. Treatments were zeolite at three levels (0, 3 and 6 weight percent), vermicompost at three levels (0, 3 and 6 weight percent) and hydrogel at there levels (0, 0.2 and 0.4 weight percent). Traits of plant height, number of leaf, flower and seed per plant, wet and dry weight of entire plant, yield of flower and grain per plant were measured. As to the result, the interatctive effect of zeolite, hydrogel, and vermicompost had a significant effect on all the tarits except number of flower, and flower yield. Most of these traits increased to increasing zeolite and vermicompost along with increasing hydrogel to 0.2%. Interactive double effects of tratments had a significant effect on number of flower per plant and flower yield.
