Effect of planting time and spacing on growth, flowering and spike yield of gladiolus

摘要

An investigation was conducted at the Horticulture Research Farm, Babasaheb Bhimrao Ambedkar University (A Central University), Vidya-vihar, Rae Bareli Road, Lucknow - 226025 (U.P.) to study the impact of spacing and time of planting on growth, flowering and corm production of gladiolus (Gladiolus grandifloras L. Aldebaran'). The experiment consisted of 16 treatments laid out in factorial randomized block design with three replications. Corms were sown in different times (November 5, 15, 25 and December 5) and different spacing at 20x30, 20x20, 30x30, 30x40 cm spacing. The study showed that better improvement in vegetative growth and floral characters was observed in treatment S2Di i.e., when the gladiolus corms are planted on November 15 and at 30x30 cm spacing. It was also observed that corm and cormels weight, number of corm and cormels were significantly varied in spacing and time of planting and it was best under S2D1 i.e., 30x30 cm spacing and November 15 planting. It is concluded that gladiolus corm (Aldebaran') planted on November 15 (Di) and at 30x30 cm spacing (S2) performed better and showed higher corm production as well as good flower characteristics under Lucknow condition.
