A factorial experiment comprised of two varieties viz. B-385 (V2) and KS-282 (V1)
along with four fertilizer treatments, was conducted at University of Agriculture,
Faisalabad. The treatments for nitrogen application techniques used were T1 (control),
T2 (½ N + total P + total K applied at transplanting). T3 (1/3 N at transplanting,
1/3 N at tillering and 1/3 N at flowering stage) and T4 (total NPK applied at
transplanting). V1 produced more panicles bearing tillers (7.76), 1000-grain weight
(22.97 gm), paddy yield (2.92 kg), No. of tillers (8.16), No. of spikelets (122.4),
1000-grain weight (23.64), yield (2.85 kg) and harvest index (30.275). The treatment
T2 followed the T3 in the above mentioned parameters which were statistically
at par. PK-NK% were non-significant whereas to NK% are also behave similarly under
different treatments. Tillering, panicle formation and seed setting are the critical
stages contributing maximum to yield. The application of fertilizer in three split
dose with a little more stress at panicle initiation stage is best technique to
increase paddy yield.]]>
