Description A field experiment “Studies on effect of mulches and micronutrient foliar sprays on growth and flowering in gladioli (Gladiolus grandiflorus L.)” was conducted at AICRP on Floriculture , Agricultural Research Institute, Rajendranagar, Hyderabad during the year 2010-2011. The experiment was laid out in Randomized Block Design comprising of ten treatments , T1-Black polythene mulch (25µ), T2- Black polythene mulch (25µ) + 1.0% FeSO4, T3- Black polythene mulch (25µ) + 0.75% ZnSO4, T4- Red polythene mulch (25µ), T5- Red polythene mulch (25µ) + 1.0% FeSO4, T6-Red polythene mulch (25µ) + 0.75% ZnSO4, T7- White polythene mulch (25µ), T8- White polythene mulch (25µ) + 1.0% FeSO4, T9-White polythene mulch (25µ) + 0.75% ZnSO4, T10-Soil mulch(control). The entire field was replicated thrice.
The results of the experiment revealed that among the mulches, Black polythene mulch recorded earliest sprouting and soil mulch i.e, control the late sprouting. The treatment T2 produced tallest plant while the maximum leaf area was produced in treatment T3. There was no effect of any of the treatments on the number of leaves of the gladiolus plant.
Earliness in days taken for spike initiation, and the maximum number of spikes per plot was observed in T1(Black polythene mulch 25 µ) while minimum days for 50% flowering and days for basal flower opening was observed in T2. Spike quality attributes like spike length, florets per spike, weight of spike, diameter of flower were more for the treatment T2 but the increase in rachis length was observed in T3. No significant difference were observed for the characters like number of spikes per plant and number of florets open at a time among different treatments.
Corm weight per plant and size of corms was highest in treatment T2 and the similar trend was observed for number of cormels per corm and cormel weight.
N, P, K and Zn content of the gladiolus plant were observed maximum with the treatment T3 while the treatment T2 recorded maximum content of the iron in gladiolus plant.
The worked out economics revealed that, the maximum B:C ratio was obtained from the plots applied with Black polythene mulch and FeSO4 1.0% (T2).
