Ornamental kale (Brassica oleracea L. var. acephala DC.) is an outstanding foliage plant with a vast range of leaf colours and shapes. Plants thrive in low-to-high areas, such as hills and plains. Ornamental kale is more closely related to wild cabbage than most domesticated forms of the vegetable. Owing to its vibrant, multi-shaped leaves and robu...

Steel slag, a waste from steel manufacturing, cannot be directly used in agriculture despite its nutritional characteristics. The present research deciphered the response of sulfur enriched steel slag (16-20% S) on cauliflower, cabbage and capsicum. The performance of steel slag based sulfur fertilizer (SSSF) at 30, 45 and 60 kg S ha-1 with 100 and...

Bougainvillea is one of the important ornamental crop with numerous use in floriculture and landscaping.

The developed method for the mixture of six fungicides (azoxyst...

The ornamental kale, scientifically known as Brassica oleracea var. acephala, stands out as an attractive plant admired for its vibrant leaves that grace the winter season. Notably, the hybrid KTOK-28-1 × KTOK-40-1 demonstrated the highest embryogenesis rate, yielding 56.12 embryos per Petri dish. This efficiency largely hinges on the characteristi...

Genotypes grown in multi-environmental trials may respond differently to a range of climatic factors, soil characteristics and cultural management practices. As such, the proportion of the variation in the phenotypic traits due to the main effects of genotype, environment and their interaction is routinely assessed when selecting best-performing li...
