Effect of Substrate, Growth Condition and Nutrient Application Methods in Morphological and Commercial Attributes of Hybrid Rose (Rosa indica L.) Cv. Kardinal

Abstract

Rose is an important plant around the world. The largest trader of rose cut-flower and hybrid varieties is Netherland. Countless varieties are introduced in agriculture business for commercial production. While countless soil and soilless substrates are also utilized for commercial production of rose around the globe. Due to that it is important to standardize and see the best soil or soilless substrate for better production of commercial cut-flowers in Rose. Various soil substrates and growing environment (Under partial shade, 70% sunlight and open sun light) was observed for better commercial yield in Rose. The balance fertilizer was applied in both A: Foliar spray (300:300:300 ppm of NPK) along with the various soil substrates of GS: PR: CCD (1:1:1), GS: LC (1:1), GS: PR (100%) and FYM: SL: CL (1:1:1). The liquid substrate was distilled water for foliar application. The foliar application was done after each day. The other nutrient application process was B: soil application of macro nutrient (2g/L of 17:17:17-NPK) along with GS: PR: CCD (1:1:1), GS: LC (1:1), GS: PR (100%) and FYM: SL: CL (1:1:1). Each plant was saturated with 2 days interval. The fertigation was carried by mixing above mentioned fertilizer with the canal water having EC: 0.4 dSm-1 and pH: 6.9 pH. The performance of plants was observed by observing the attributes such as Plant survival (%), Number of flowers per plant, Plowers stem length (cm), Plant health (Number of leaves, leaf size (cm), Flower diameter (mm), Flower stem size (mm) and Flower stem diameter (mm). Completely randomized experimental design (CRD) was used for calculating means of various treatments. The best treatment was FYM: SL: CL for both under partial shade (70%) and open sun light for the significant growth and development of plant morphological and commercial attributes. The same treatment with soil application of 2g/L of NPK (17:17:17) after each day is recommended to the commercial growers of Rose throughout the flowering season.
