Summary
Gladiolus production systems demand precise nutrient management to ensure high quality spikes and propagative-sized corms. However, conventional recommendations are generalised and often ignore the spatial and temporal heterogeneity of soils, adversely affecting nutrient availability and plant uptake. To address these issues and to refine the existing practices, A field study was conducted in gladiolus cv. Trader Horn to develop a site-specific nutrient management strategy using soil test crop response (STCR) approach. The experiment involved creating fertility gradients and applying various combinations of N, P, K, and FYM in a fractional factorial randomised block design. Results revealed that producing 100 kg of spikes required 0.96 kg N, 0.16 kg P, and 0.98 kg K, while 100 kg of corms
