چکیده مقاله :
Baby’s breath has value as an ornamental in floriculture and is a major export for several countries. To maintain the production of baby’s breath, proper nutrient management by application of nutrient sources favorable for ornamental flowering plants is advised. Hence, this study was conducted to assess the performance of a baby’s breath in terms of growth, yield, and return on investment as influenced by different concoctions and rates of inorganic fertilizers. An area of 100.80 m2 was laid out into five blocks adopting the 4 × 4 factorial experiment in Randomized Complete Block Design (RCBD). The treatments were designated as follows: For factor A (concoction) – C0-without concoction; C1-fermented plant juice at 2 v/v%; C2-fermented fruit juice at 2 v/v%; C3-calcium phosphate at 5 v/v%, and factor B (inorganic fertilizer) – F0-without fertilizer; F1-90-60-60 N, P2O5, K2O ha-1; F2-45-30-30 N, P2O5, K2O ha-1; F3-25-15-15 N, P2O5, K2O ha-1. The concoctions and the inorganic fertilizer at 25-15-15 N, P2O5, K2O ha-1 both gave a significant plant height to the baby’s breath at 28 DAP. The calcium phosphate at 5 v/v% plus 25-15-15 N, P2O5, K2O ha-1 (T15) was the best combination for improving the plant height of the baby’s breath at 28 DAP, however, all fertilizers affected the baby’s breath similarly to no fertilizer applied in terms of the production of suckers, flowers, and marketable flowers for three months of raising. Thus, the monetary return was negative.
گل صدفی در گلکاری ارزش خاصی دارد و برای صادرات به چندین کشور مدنظر است. برای حفظ عملکرد گل صدفی در سطح مطلوب می بایست مدیریت تغذیه مطلوبی با کاربرد منابع تغذیه ای مطلوب در راستای گلدهی گیاهان زینتی گلدار، انجام شود. بنابراین این مطالعه برای دستیابی به رشد، عملکرد و بازگشت سرمایه در گل صدفی با استفاده از آمیزه ها و مقادیر کودهای غیرآلی انجام شد. مساحت 100/8 مترمربع به 5 بلوک 4×4 متر برای اجرای آزمایش فاکتوریل بر پایه طرح RCBD آماده شد. تیمارها به قرار زیر بودند: فاکتور A (آمیزه های کودی) شامل: C0: بدون آمیزه کودی؛ C1: عصاره گیاهی تخمیر شده به نسبت 2 درصد حجمی؛ C2: عصاره تخمیر شده میوه به نسبت 2 درصد حجمی و C3: فسفات کلسیم به نسبت 5 درصد حجمی. فاکتور B (کود غیرآلی) شامل: F0: بدون کود؛ F1: 60-60-90 (N-P2O5-K2O) در هکتار؛ F2: 30-30-45 (N-P2O5-K2O) در هکتار؛ F3: 15-15-25 (N-P2O5-K2O) در هکتار. آمیزه و مقدار کودی 15-15-25 از نظر ارتفاع بوته 28 روز بعد از کاشت برتری معنی داری داشت. فسفات کلسیم به نسبت 5 % حجمی و 15-15-25 (T15) بهترین ترکیب تیماری برای افزایش ارتفاع گل صدفی 28 روز پس از کاشت بودند، البته همه کودها نسبت به شاهد از نظر تولید پاجوش، گل و گل های بازارپسند به مدت 3 ماه شبیه شاهد بودند. بنابراین می توان گفت از نظر بازگشت سرمایه، بیلان منفی بود.
