Fertilizer management studies on growth and productivity of hybrid Indian mustard Brassica juncea (L.)

Abstract

A field experiment, consisting of four levels of recommended dose of fertilizer (NPK & S: 80, 40, 0 & 60 kg/
ha) viz. 75 %, 100 %, 125 % & 150 % of RDF and four varieties of Indian mustard [Brassica juncea (L)
Czern & Coss.] viz. DMH-1, NRC-HB 506, PAC-437 and Kranti (National Check), was carried out in split
plot design with three replications during rabi 2009-10 and 2010-11. Hybrid cultivar DMH-1 performed best
in terms of yield and yield attributing characters, followed by NRC-HB 506, which were found significantly
higher over the PAC-436 and Kranti (NC) under different fertility levels. Application of 100 % RDF (80 kg
N + 40 kg P2O5) produced significantly higher seed yield (2372 kg/ha) and other yield attributes viz. number
of primary branches / plant (4.55), number of secondary branches / plant (9.40), number of siliquae / plant
(195.35), seed weight (8.27 g/plant) test weight (4.63), stover yield (4771 kg/ha), oil content (41.30%) , oil
yield (933 kg/ha), total N uptake (114.94 kg/ha ), total P uptake (27.21 kg/ha ), net return (Rs.36776) and B:C
ratio (2.62) as compared to 75 % RDF and found statistically at par with 125 % & 150 % RDF. Hence, the
farmer’s could economically benefited by using DMH-1 Indian mustard hybrid variety with recommended
doses of fertilizers.
