Abstract

A field experiment was carried out at Qazvin-Iran during 2009-2010 to assess the effect of different levels of nitrogen (N0, N75, N150 and N225 kg ha-1 ) and potassium (K0, K45, K90 and K135 kg ha-1 ) on yield and some of the agronomical characteristics in Mustard (Brassica juncea). Experiment was conducted as factorial randomized complete block design with three replications. The results showed that increased amount of nitrogen and Potassium up to 225 kg N ha-1 and 135 kg K ha-1 respectively had a positive and significant (p

Highlights

Introduction elevation in different levels ofPotassium (Amanullah et Mustard (Brassica juncea) is considered one of the al., 2011).most important oil seed crops in all over the world and Addition of NKP fertilizers increase the crop yield as in Iran
Of all the essential purpose of this experiment was to study the impact of nutrients, nitrogen as an important limiting factor in crop different levels of nitrogen and potassium on yield and productivity is required by the Mustard in its largest some of the agronomical characteristics in Mustard
Nitrogen supports the plant with rapid growth, and 225 kg N/ha) and four levels of Potassium (0, 45, 90 increasing seed and fruit production and enhancing and 135 kg K/ha) and was laid out in completely quality of leaf and oil seed crops (Allen & Morgan, 2009). randomized block design replicated three times and a net Nitrogen management is crucial in cropping system; it plot size of 1.8m x 6m

Summary

Introduction

Introduction elevation in different levels ofPotassium (Amanullah et Mustard (Brassica juncea) is considered one of the al., 2011).most important oil seed crops in all over the world and Addition of NKP fertilizers increase the crop yield as in Iran. Nitrogen fertilizer at the flowering stage significantly chemical property showed that the experimental soil was improves the seed yield and quality in most crops (Vijaya clay-loam in texture containing 0.83% OC, 1.33 (ds/m) et al, 2011). The results suggest that the treatments N225, K135 gave significantly the highest (1319, 1170 kg ha-1) and N0, K0 the lowest (367.4, 727.2 kg ha-1) SOY respectively (Table 2).
