Abstract:
The present investigation entitled “Effect of soaking with plant growth regulators on growth, yield and quality of Gladiolus (Gladiolus grandiflorus)’’ was carried out during winter season, 2021-22 at Horticultural Farm, College of Horticulture, Sardarkrushinagar Dantiwada Agricultural University, Jagudan, Dist. Mehsana, Gujarat. Experiment was laid out in randomized block design with three replications and was planted by soaking the corms for 24 hours in different plant growth regulators. viz. GA3, NAA and BA. Total thirteen treatments were evaluated in the present study viz., T₁: without soaking; T₂: Soaking in 50 ppm GA3; T₃: Soaking in 100 ppm GA3; T₄: Soaking in 150 ppm GA3; T₅: Soaking in 200 ppm GA3; T₆: Soaking in 50 ppm NAA; T₇: Soaking in 100 ppm NAA; T₈: Soaking in 200 ppm NAA; T₉: Soaking in 300 ppm NAA; T₁₀: Soaking in 25 ppm BA; T₁₁: Soaking in 50 ppm BA; T₁₂: Soaking in 100 ppm BA and T₁₃: Soaking in 150 ppm BA. Treatments were evaluated with respect to growth, yield and quality parameters of Gladiolus. Among various treatments, soaking in 100 ppm GA3 was found significantly superior to rest of the treatments with respect to growth, spike yield, cormel yield and quality. However, treatment soaking in 100 ppm BA was found significantly superior among all the treatments with respect to maximum number of sprouts per corm and maximum number of corms per plant, per plot and per hectare. On the basis of economics of the treatments, the highest benefit cost ratio and net realization obtained with treatment of GA3 at 100 ppm.
