A field investigation was conducted at the Department of Horticulture, Dr. PDKV Akola Maharashtra during the rabi
season of 2014-2015 to determine the requirement of nitrogen and phosphorus for coriander variety Hisar Anand for achieving maximum seed yield and benefit cost ratio. Four different levels of nitrogen (40, 50, 60 and 70 kg/ha) and three different levels of phosphorus (30, 40 and 50 k/ha) in different combination were distributed in the plots. The experiment was laid out in Factorial Randomized Block Design with 3 replications. Available N and P levels in soil after harvesting was non-significantly affected with different nitrogen and phosphorus combinations. There was a significant effect of application of these two nutrients on most of the seed yield attributes of coriander up to a certain limit. The results indicated that yield parameters were declined with very high rate of nitrogen. Therefore, significantly maximum number of umbels per plant (17.93), umbellate per umbel (6.69), seeds per umbel (18.34), seed yield per plant (4.01 g), seed yield per plot (341g) and seed yield per hectare (12.36 q), was recorded with treatment T11
kg/ha) instead of highest dose of both nutrients. For two parameter viz.,
umbellate per umbel and seeds per umbel interaction effect was found to be non- significant. The highest net return, highest gross return and highest benefit cost ratio was recorded with same treatment T11
kg/ha). Therefore, The treatment combination of (N60
kg/ha) was observed to be the best and most profitable dose for coriander cultivation on black cotton soil of Akola, Maharashtra.
