Abstract:

The experiment was carried out during Rabi 2012-13 and 2013-14 at Agricultural Research Station, Gangavathi to study the effect of SSNM practice by using nutrient expert on hybrid maize (GK-5029) under zero tillage in TBP command areas of Karnataka. The pooled data of two years revealed that among main plots there was no significant difference between mulch and without mulch treatments with respect to growth and yield parameters. Among different target yield levels, significantly higher grain and stover yield was recorded with SSNM based on target yield of 10 t ha-1 (9.40 and 9.84 t ha-1, respectively) as compared to other target yield treatments and recommended dose of fertilizer which recorded significantly the least grain and stover yield (4.90 and 5.72 t ha-1, respectively). Gross returns, net returns and B: C ratio were also significantly higher with SSNM based on target yield of 10 t ha-1 (Rs.1,41,070, Rs. 1,10,803 and 3.59, respectively) as compared to other target yield levels and recommended dose of fertilizer which recorded significantly the least gross returns, net returns and B:C ratio (Rs. 74,232, Rs. 46,143 and 2.65, respectively). Irrespective of the tillage methods maize yield was significantly higher with SSNM based on NE for the target yield of 10 t/ha as compared to state RDF and farmers practice. It could be concluded that, SSNM practice based on “Nutrient expert” can be achieve target yield of hybrid maize up to 9.40 t ha-1 in TBP command area of Karnataka.
