Aim: A field experiment
was conducted during winter season to study the effect of different nutrient
management on growth and productivity of potato (cv. Kufri Jyoti) and soil
nutrient status in new alluvial zone of West Bengal.
experimental site is located at Regional Research Station, New Alluvial Zone
of Bidhan Chandra Krishi Vishwavidalaya, Gayeshpur, Nadia, West Bengal at an
altitude of 9.75m amsl. The experiment was laid out in a randomized block
design with three replications and consisted of eight different treatments.
Observations on growth and yield attributes were recorded and soil nutrient
analysis was carried out before planting and after harvest of potato.
highest values of plant height (48.47 cm), dry matter accumulation (686.70 gm-2)
and crop growth rate (7.78 gm-2day-1) was observed in
the treatment (T7)? receiving 100% recommended dose of fertilizer,
which was statistically at par with integrated nutrient management receiving
50% RDF + 50% N as farmyard manure . Similarly, 100% RDF (T7)?
gave better yield parameters like dry weight of tuber (547.95 gm-2),
number of tubers per hill (5.57), tuber bulking rate (9.33 gm-2)
and maximum tuber yield of 22.19 t ha-1 which was also
statistically at par with integrated nutrient management receiving 50% RDF +
50% N as farmyard manure with tuber yield of 21.72 t ha-1.
However, organic nutrient management containing 1/3rd recommended
N each from farmyard manure, vermicompost, neemcake along with rock
phosphate, phosphorus solubilizing bacteria and Azotobacter showed
significantly highest organic carbon content, total nitrogen, available
phosphorus and available potassium content in soil among the various organic
treatments followed by integrated nutrient management. ??
growth and yield attributes of potato were found to be significantly improved
in the treatment receiving 100 % recommended dose of fertilizer and 50% RDF +
50% N as farmyard manure, respectively. However, all the organic based
treatments showed significant improvement in soil nutrient status like
organic carbon, total nitrogen, available phosphorus and available potassium.
