Description The field experiment entitled “Maximization of maize productivity
through targeted yield approach” was conducted at ZARS, UAS, GKVK,
Bengaluru during kharif season 2011 on red sandy loam soil, to find out
the performance of maize under the targeted yield approach. The soil of
the experimental site was slightly acidic in reaction (pH 5.64), low in
organic carbon content (0.45 %) and EC (0.15 dSm-1). The experiment
was laid out in a randomized complete block design with ten treatments
replicated thrice. The treatments includes SSNM through fertilizers for
targeted yield of 8 and 10 t ha-1, SSNM through INM for targeted yield of
8 and 10 t ha-1, STCR through fertilizers for targeted yield of 8 and 10 t
ha-1, STCR through INM for targeted yield of 8 and 10 t ha-1. These eight
treatments were compared with 100 per cent RDF and 100 per cent RDF
+ FYM @ 10 t ha-1.
SSNM through fertilizers for targeted yield of 10 t ha-1 recorded
significantly higher grain yield (9.77 t ha-1) and stover yield (11.25 t ha-1)
and significantly higher growth attributing characters like plant height
(204.7 cm), number of leaves (6.93), leaf area (4003.3 cm2 per plant) and
dry matter production (501.4 g plant-1), yield attributing characters like
cob length (20.3 cm), number of grain rows per cob (20.5), number of
grain per rows (41.3), test weight (32.9 g) and higher total nutrient
uptake (504.8, 103.5, 221.3 N, P2O5 and K2O kg ha-1, respectively) and it
was on par with STCR through fertilizers for targeted yield of 10 t ha-1.
However higher B:C ratio (4.0) was recorded in STCR through fertilizers
for targeted yield of 10 t ha-1. The organic carbon after harvest was
increased (0.56 %) in SSNM through INM for targeted yield of 10 t ha-1,
EC (0.163 d Sm-1) increased in SSNM through fertilizer for targeted yield
of 10 t ha-1 and 8 t ha-1 and pH was increased in STCR through INM for
targeted yield of 10 t ha-1 and SSNM through INM for targeted yield of 10
t ha-1 (5.70) as compared to before sowing of crop. The research aims at
determining the effect of targeted yield approach on grain yield, economic
efficiency of maize and soil chemical and biological properties.
