Abstract

Gladiolus (Gladiolus grandiflorus L.) is a significant flower crop in India. The crop's yield and productivity have been significantly lower than both regional and national standards due to various factors. The primary factor is the lack of location-specific fertilizer recommendations, among others. Thus, a field experiment was conducted for two consecutive seasons at the Horticulture Research Farm, Faculty of Agriculture Sciences and Associated Industries, Rama University, Kanpur, during the academic years 2020-2021 and 2021-2022. (U.P.). A Randomized Block Design was utilized in the experiment, with 13 treatments and three replications with various doses of N, P2O5, and K2O. The main objectives of the experiment were to evaluate how N, P2O5, and K2O affected the yield characteristics and economics of Gladiolus (Gladiolus grandiflorus L.) Cv. Nova Lux. According to the results of the current study, Treatment T11(NPK @150:100:120) had the best effects on yield attributes like Number of Spikes [1.29 (202021), 1.31 (2021-22) and 1.30 (Pooled)], Weight of Spike [57.54 (2020-21), 59.02 (2021-22) and 57.85 (Pooled)] g, Number of florets per spike [17.33 (2020-21), 17.49 (2021-22) and 17.41 (Pooled)], Fresh weight of florets [3.32 (2020-21), 3.44 (2021-22) and 3.38 (Pooled)] g, dry weight of florets [0.73 (2020-21), 0.76 (2021-22) and 0.74 (Pooled)] g, Yield of Spikes per hectare [49.48 (2020-21), 52.49 (2021-22) and 50.99 (Pooled)] q/ha, Vase life of Spike [7.83 (2020-21), 7.92 (2021-22) and 7.88 (Pooled)] days, Number of Corms per plant [2.10 (2020-21), 2.11 (2021-22) and 2.10 (Pooled)] & Diameter of corms [5.42 (2020-21), 5.49 (2021-22) and 5.46 (Pooled)] cm. Treatment T11 (NPK @150:100:120) was also found with highest gross returns (370000.02 Rs/ha), Net returns (270893.02 Rs/ha) & B:C ratio of 2.73 when compared to the other treatments. However, Lowest Benefit Cost ratio (1.92) was recorded in treatment T0, i.e., control.

Conclusion

From the results of the current experiment, it can be inferred that Treatment T11(NPK @150:100:120), had the best effects. It was deemed to have the best yield attributes including Number of Spikes, Weight of Spike (g), Number of florets per spike, Fresh weight of florets (g), dry weight of florets (g), Yield of Spikes per hectare (q/ha), Vase life of Spike (days), Number of Corms per plant and Diameter of corms (cm). Also, Highest Net returns (270893.02 Rs/ha) was recorded in treatment T11 (NPK @150:100:120) whereas both treatment T11 and T10 were found with same B:C ratio of 2.73. However, Lowest Benefit Cost ratio (1.92) was recorded in treatment T0, i.e., control.
