Rp. Singh et al., Effect of integrated nutrient management on productivity of pearlmillet (Pennisetum glaucum)-wheat (Triticum aestivum) cropping system, I J AGRON, 44(2), 1999, pp. 250-255
In a field experiment conducted at Hisar from 1984-85 to 1996-97, integrati
on of chemical fertilizers and organic manures in the form of FYM or green
manure in the ratio of 50:50 or 75:25 applied in pearlmillet (Pennisetum gl
aucum L.) and followed by 100% recommended dose of fertilizer in wheat ( Tr
iticum aestivum L. emend Fiori & Paol) crop gave the yield at par to that o
f when 100% recommended dose of fertilizers was applied to both the crops o
f the sequence. These treatments were significantly better than control and
farmer's practice. The 4.63-43.27% and 35.27-47.18% higher yields were obt
ained in pearlmillet-wheat respectively over farmer's practices. in general
, the NPK status decreased successively after harvesting of both the crops
of the sequence due to removal of nutrients in large quantity by the crops.
After more than one decade of experimentation at permanent site the nutrie
nt status of soil under control and lower doses of fertilizer application d
eclined to a much higher degree as compared to the application of either 10
0% recommended dose of chemical fertilizers or combination of organic and i
norganic fertilizers.
