Application of all the macro- and micronutrients
together resulted in an 81% increase in grain yield over
control (P < 0.05). No decrease in grain yield over the
maximum (obtained with all nutrients), however, occurred
in the treatment without starter N (-N) (Table 1), presumably
because of effective native Rhizobium population
in the NARC soils (Aslam et al. 2000). Similarly, no
yield reduction was observed without Fe application to
this Fe-efficient chickpea cultivar CM-72 (Rashid and
Din 1993). Also, chickpea plants did not exhibit
symptoms of iron chlorosis in the control and -Fe treatments.
A statistically non-significant yield reduction of
10% was observed without K application (Table 1).
Yield reduction without P, B, and Zn was, however,
rather drastic: 31% each without P or B and 30% without
Zn (
