Abstract:

Integrated use of inorganic and organic manures has become important for higher agricultural produce as no single source of plant nutrients, either it is chemical, organic or bio fertilizers can meet the entire needs of crop. Bio-fertilizers add nutrients through the natural processes and stimulating plant growth through the synthesis of growth promoting substances and thus help in sustainable crop production through maintenance of soil productivity. Two year study was conducted at the research farm of the Division of Floriculture & Landscaping, Indian Agricultural Research Institute, New Delhi during 2016-17 and 2017-18 under integrated nutrient management approaches using two IARI, gladiolus hybrids as Melody Open Seedling and P-16-1 x Eurovision in split plot design with three replications and twelve treatment combinations. The two year mean data revealed that application of organic, inorganic and bio fertilizers had produced significant effect on vegetative and corm production parameters viz., days to first flowering, plant height, spike length, number of florets per spike, number of marketable spikes and number of corms per hectare. The data indicated that between two hybrids, P-16-1 x Eurovision hybrid had showed earliness and taken minimum 85.75 and 88.50 days respectively during both years. Among the hybrids, average maximum plant height (111.50 cm and 108.16 cm) was recorded in Melody Open Seedling which was significantly lengthier than the P-16-1 x Eurovision hybrid during both the year. Significant variation was also observed for spike length and mean of two year showed maximum spike length (100.91 cm and 98.16 cm) respectively in Melody Open Seedling hybrid. The interaction effect of INM treatments on marketable spikes per hectare and that was maximum under treatment T7 with hybrid Melody Open Seedling and recorded 3.450 lakh spikes per ha during first year and 3.500 lakh per hectare during second year respectively. Maximum number of corms (3.950 lakh/ha) was recorded during first year and during second year, it was again produced (4.00 lakh/ha corms) in hybrid Melody Open Seedling with the application of 125 % RDF + Azospirillum +PSB. Further, the treatment T4 i.e. application of FYM @ 10 t/ha resulted in the highest number of corms (3.712 lakh/ha) giving maximum gross income of Rs. 7.425 lakh/ha and net realization of Rs.4.225 lakh/ha and gave the highest CBR (1:2.32).
