“…The increased number of spikes under optimum dose of nitrogen may be attributed to more number of flowers per spike. The findings were comparable with Sendhilnathan and Manivannan (2019) in tuberose, Gowthami et al (2018) and Priyanka et al (2018) in crossandra.…”

An experiment was carried out during the year 2022-2024 in the Department of Horticulture, Faculty of Agriculture, Annamalai University Tamil Nadu to find out the suitable level of nitrogen to be used in combination with nano urea to increase the growth and yield of crossandra (Crossandra infundibuliformis L.) cv. Lakshmi. The experiment was laid out in Randomized Block Design with 14 treatments and 3 replications. Among the different treatments, the treatment T5 (100% PK + 75% N through urea + 0.4% Nano urea (3 sprays)) resulted in increased growth attributes such as plant height (85.21 cm), stem girth (7.95 cm), number of branches plant-1 (24.51), number of leaves plant-1 (99.29), plant spread in North-South and East-West direction (53.52 cm and 62.43 cm respectively), leaf area (95.41cm2 ), chlorophyll content (0.840 mg g-1 ) and dry matter production (91.53 g plant-1 ). But, the treatment T8 (100% PK + 50% N through urea + 0.4% Nano urea (3 sprays)) resulted in increased yield attributes like maximum number of spikes plant-1 (36.27),number of flowers spike-1 (39.21), flower yield plant -1 (51.03 g),flower yield plot-1 (974.76 g plot-1 ), estimated flower yield hectare-1 (32.49 q ha-1 ) The treatment control (T1) had the lowest value for all the growth and yield attributing characters. Overall, it is concluded that the application of 100% PK + 50% N through urea + 0.4% Nano urea (3 sprays) (T8) was found to be the best combination for improving the growth and yield of crossandra.

“…Crossandra is also known as a 'firecracker plant' due to the cracking sound heard during the splitting of the seed pods upon drying (Gowthami et al, 2017) [13] . It has a remarkable range of colours varying from orange, pink, red, yellow and double-coloured blue types with a white throat.…”

The study was conducted at the Floriculture department, Horticulture College Munirabad, Koppal district. The experiment was designed in a Randomised Completely Block Design (RCBD) with ten genotypes. Flower yield exhibited a significantly positive correlation with the spike count per plant, number of flowers per spike, spike length, shelf life, leaf area, total chlorophyll, 100 flower weight, plant height, flower diameter, primary branches per plant and secondary branches per plant. At the same time, traits like days to fifty percent flowering and days to first harvest recorded the highest negative correlation with many traits. In the present investigation, the results of path coefficient analysis reveal that shelf life, total chlorophyll, number of flowers per spike, and plant height directly affect flower yield. Meanwhile, the flower diameter, and days to fifty percent flowering negatively affected flower yield.
