Effect of nutrient management on yield and nutrient uptake by Indian mustard (Brassica juncea L)

Abstract

A field experiment was conducted during rabi season, 2015-16 to study the Effect of nutrient management on yield and nutrient uptake by Indian mustard (Brassica juncea L.) varietyPusa Bold at Crop Research Centre Chirori, Meerut. The soil of experimental field was sandy loam texture, alkaline in nature with pH (8.2), low in organic carbon, available nitrogen, phosphorus, potassium,sulphur, zincand boron.Twelve treatments in different nutrient management practices consisting Control,100% NPK, 100% NPK+20 kg S ha-1, 100% NPK+40 kg S ha-1, 100% NPK+1.5 kg B ha-1, 100% NPK+20 kg Zn ha-1, 100% NPK+20 kg S ha-1+1.5kg B ha-1, 100% NPK+20 kg S ha-1+20 kg Zn ha-1, 100% NPK+40 Kg S ha-1+1.5 kg B ha-1, 100% NPK+40 kg S ha-1+20 kg Zn ha-1, 100% NPK+20 kg S ha-1+1.5 kg B ha-1+20 kg Zn ha-1and 100% NPK+40 kg S ha-1+1.5 kg B ha-1+20 kg Zn ha-1 were tested in randomized block design with three replication.The experimental results revealed that significantly higher yield (grain and stover),nutrient uptake(N,P, K, S, Zn and B) by grain and stoverwere noticed with the application of 100% NPK+40 kg S+1.5 B+20 kg Zn ha-1 as compared to rest of the treatments.
