Abstract:
The experiment entitled “Effect of intercropping (leafy vegetables) on growth and yield of marigold (Tagetes patula) at different levels of nitrogen in the Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj during the month of December 2020 to March 2021. The experiment was conducted in Randomized Block Design replicated thrice with ten treatments viz., T0 (RDF of marigold); T1 (RDF of marigold + coriander); T2 (RDF of marigold + ½ RDN of coriander); T3 (RDF of marigold + 2/3rd RDN of coriander); T4 (RDF of marigold + spinach); T5 (RDF of marigold + ½ RDN of spinach); T6 (RDF of marigold + 2/3rd RDN of spinach); T7 (RDF of marigold + fenugreek); T8 (RDF of marigold + ½ RDN of fenugreek) and T9 (RDF of marigold + 2/3rd RDN of fenugreek). The maximum plant height (31.8 cm), plant spread (35.1 cm²) and number of branches (14) were recorded highest in T6 (RDF of marigold + 2/3rd RDN of spinach). Days for flower bud initiation (38) and first flower opening (62) was also least in T6 (RDF of marigold + 2/3rd RDN of spinach). Whereas, flower diameter (80mm) was recorded highest in T9 (RDF of marigold + 2/3rd RDN of fenugreek) amd T1 (RDF of marigold + coriander) respectively. The number of flowers (63) and yield of flowers per hectare (285 q ha-1) was recorded highest in T6 (RDF of marigold + 2/3rd RDN of spinach).
