Summary
A field experiment was conducted in Leo, Himachal Pradesh, India, to study the effect of combined use of NPK and farmyard manure (FYM) on yield attributes, yield, nutrient uptake by onion (Allium cepa) as well as on build up of available N, P, K during the summer seasons of 1998 and 1999. The treatments involved 3 levels of FYM (0, 10 and 20 tonnes/ha) and 4 levels of NPK (0, 50, 100 and 150% of the recommended dose, which is 125 kg N, 33 kg P and 50 kg K/ha). Application of fertilizers at the rate of 100 (125 kg N, 33 kg P and 50 kg K/ha) and 150% (187 kg N, 49 kg P and 75 kg K/ha) of recommended dose registered an increase of 42 and 56% over 50% NPK level in bulb yield of onion. Similarly, application of FYM at 10 and 20 tonnes/ha increased bulb yield by 9 and 19% over 100% NPK alone, respectively. Bulb yield recorded in the case of 100% NPK along with 20 tonnes FYM/ha (19.87 tonnes/ha) was at par with 150% NPK alone (18.82 tonnes/ha) thereby signifying the savings of chemical fertilizers of 52 kg N, 16 kg P and 25 kg K/ha. Use of NPK fertilizers along with FYM also resulted in significant improvement in available N, P, K status of the soil.
