Abstract
A laboratory experiment was conducted to evaluate the manural potential of farmyard manure (FYM), vis-a-vis 25%, 50% and 100%
recommended dose of two standard, commercial rate of NPK fertilizer (i.e 120:60:30) and to find out the most productive cropping
system at various strength of chemical fertilizers and organic manures. In the given research the performance of organic fertilizer for
compromising with expensive inorganic fertilizer was studied with respect to the growth of wheat (Triticum aestivum L.). The policy
led to the minimal usage of high quantity fertilizer with the output of quality production.
Experiment comprised fertility level of NPK @120:60:30 along with FYM @ 5t ha-1
(aprox. 2.5gm/litre) NH4NO3, CaHPO4. 2H2O,
KCL were used as sources of N, P2O5 and K2O, respectively. In the given research all growth parameters including SL, RL, SFW,
SDW, RFW and RDW of wheat was recorded maximum at 25% NPK (1/4th strength). Application of FYM @ 5 t ha-1
, at 120:60:30
NPK, to compensate the low strength of NPK was favored at both strength 25% and 50% NPK and produced significantly higher
growth in wheat than all other single treatments. It has been realized from experiments that neither chemical fertilizers nor organic
manures alone can achieve sustainability in production, whereas the integrated use of organic and inorganic can sustain a highly
intensive production system.
