Abstract:
This study was carried out to investigate the standardization of spacing and fertilizer on growth and quality of Bachelor’s button cv.AGS-5. The treatments consisted of six fertilizer levels (F₁:150:75:75 NPK kg per ha, F₂:150:75:150 NPK kg per ha,F₃:200:75:75 NPK kg per ha, F₄:200:75:150 NPK kg per ha, F₅:250:75:75 NPK kg per ha, F₆:250:75:150 NPK kg per ha), two spacing levels (S₁: 45 cm x 30 cm and S₂: 60 cm x 30 cm) tested in factorial randomized block design with three replications. The vegetative parameter viz., plant height increased with decrease in spacing level and increase in nutrition. The interaction of S₁F₆ (45 x 30 cm: 250:75:150 NPK kg/ ha) recorded higher plant height. Plant spread, number of branches, stem girth, number of leaves. Flower production was significantly influenced by spacing at 45 x 30 cm, and nutrition at 250:75:150 NPK kg/ ha. The treatment combination of S₁F₆ (45 x 30 cm: 250:75:150 kg/ ha) produced more flower yield per ha (18.20 t/ha). It is on par with S₁F₅ i.e 17.64 t/ha. Increasing levels of spacing and nutrition increased the duration of flowering, flower diameter, flower weight, shelf life of flower on plant and seed yield significantly. Duration of flowering, flower diameter, flower weight, shelf life of flower on plant and seed yield proved superior with 60 x 30cm spacing and nutrition at 250:75:150 NPK kg/ ha.
