Abstract:
Disproportionate application of fertilizer not only increases the cost of production but also decrease overall soil fertility leads to environmental pollutions. Therefore, a field experiment was carried out by Krishi Vigyan Kendra, Cachar to evaluate the yield performance of Rajmah by use of organic manure with optimum rate of fertilizer under intensive farming system. Three trials were conducted in three different locations of Cachar district during rabi seasons of 2017-18 and 2018-19. Critical inputs like seed (HUR-301), recommended dose of fertilizer, lime and boron were distributed among the farmers. Farmers were encouraged to provide recommended dose of FYM in their field. The results revealed that the crop takes same period ie. 101 days for maturity in both trial and farmers practice plots; However, plant height of 52.87 cm and 51.75 cm, respectively recorded under trial and farmers practice plots; pod per plant were recorded as 18.2 and 16.1 under trial and farmers practice; seed per pod were 4.25 and 4.19 numbers under trial and farmers practice; physiologically mature seed weight were recorded as 17.49 and 14.96 q/ha under trial and farmers practice and benefit cost ratio were recorded as 1.64 under trial as compare to 1.42 in farmers practice. Yield increases of 16.96 percent were observed in the trial as compare to farmers practice in the farmer’s field.
