Effect of Nitrogen Application Techniques on Different Parameters of Yield in Rice (Oryza sativa)

Abstract:
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.
