Effect of Integrated Nutrient Management on Growth, Yield and Quality of Onion (Allium Cepa L.)

Abstract

I· ield cxpcrin1cnts were conducted for two consecutive years during Rahi season of 2010-11 and 2011-12 at l·lorticulture Research enter, Sardar Yallabhhhai Patel University of Agriculture and technology, Meerut, to evaluat~ the ""Effect of integrated nutrient n1anagen1ent on growth, yield and quality of onion (;1//hun cetJa 1 .~ .)'"' with 13 trcnh11~nts consisted of (,ontrol ( "vithout organic & inorganic ferti I i z~r)" 100% N'PK RDF (120: 80: 80 kg ha-1 ), 125°/o NPK 1{01\ 150~/o NPK RDF, 14YM (!~10 t ha- 1+ 25% NPK, I•YM (!il,IO t ha·1 +50% NPK. l<YM ~i'l!O t ha ·1 + 75% NPK~ JiYM (g)15 t hn- 1 -f- 25 o/o NPK, FYM ~v15 t lul -t -r 50 ~~o NPK" FYM @15 t ha· 1 + 75 °/o NPK~ FYM (!_1120 t ha -1 + 25 °/o NPK, l·YM (!v20 t ha -1 -t- 50 ~o NPK and FYM ~~20 t ha-l + 75 o/o NPK wen~ t~stcd in rundon1ized block design with three replication.
