Abstract:

A study on “Fertigation Effect in Carnation under Polyhouse in North Bihar Agro-climatic conditions” was carried out under twelve (12) treatments, i.e., 3 main treatments on variety, namely; V1: Loris; V2: Pingu and V3: Gioele, and 4 sub- treatments on fertigation, i.e., F1: 80 % fertigation of RDF of NPK; F2: 100% fertigation of NPK; F3: 120% fertigation of NPK and F4: 100% application of RDF (control) adopting split plot design. The average daily month wise water requirement per plant of Carnation was computed minimum 0.12cm in January and maximum 0.56 cm April. The total water requirement during crop period was found to be 66.56 cm. Among different varietal treatments, the treatment V2 (Pingu) recorded maximum number of branches (9.80); minimum days for bud initiation (89.83 days) and flowering(164.83 days); maximum flower diameter (7.83cm) and stalk length (60.22cm) and girth (4.43 mm) as well as maximum number of flowers per m2 area 353.The fertigation treatment F3 (120% fertigation of RDF of NPK) was found very effective, might be due to application of higher doses, resulted maximum plant heights 87.18cm at 210 DAT. Also, the number of branches (11.59); minimum time for bud formation (87.89 days), minimum days to flowering (165.11 days), maximum stalk length (57.83cm) and girth (4.91mm) as well as maximum number of flower per m2 area (353.22). The b/c ratio was also found highest in treatment F3, i.e. 2.60, 2.56 and 2.59 whereas lowest 0.81, 0.96 and 0.85 found in control treatment (F4) for Loris, Pingu and Gioele respectively.
