Agronomic Study of Fenugreek Grown under Different In-Row Spacing and Nitrogen Levels in a Paddy Field of Iran

American-Eurasian J. Agric. & Environ. Sci., 10 (4): 544-550, 2011 01/2011;

ABSTRACT Abstract: The objective of this study was to evaluate the effects of different levels of nitrogen and plant
density on yield and yield components of Fenugreek. This study was conducted at Guilan region (Iran) in a
Paddy field during 2008-2009 cropping season. The experiment was carried out using split plots based on
randomized complete block design with 4 replications. Four levels of nitrogen (0, 25, 50 and 75 kg N haG1) as
the main factor and four levels of plant density (60, 80, 100 and 120 plants mG2) as sub-plots were investigated.
Result indicated that nitrogen fertilizer effect was significant on number of pods per branch, number of pods
per plant, seed yield and biological yield. Plant density significantly a ffected biological yield (p<0.05).
The highest seed yield (1468 kg haG1) was produced by using 75 kg N haG1. There was positive and significant
correlation between seed yield and biological yield. According to mean comparisons of simple effects,
the highest biological yield belonged to 75 kg N haG1 and 120 plants mG2, respectively.

    ABSTRACT: To understand the effect of plant density and amounts of nitrogen fertilizer on some agronomic characteristics of Indian mustard, an experiment was laid out as a randomized complete block design with split-plot arrangement with three replications. Nitrogen fertilizer levels (0, 50, 100, 150 and 200 kg N/ha) were allotted to main plots and subplots were consisted of three levels of plant densities (80, 100 and 120 plants/ m2). The results indicated that, plant density had a highly significant effect on plant height, seed/siliqua, siliqua/plant, seed yield, biologic yield, 1000-seed weight, oil content and oil yield (p<0.01). All tested traits (qualitative and quantitative ones) were significantly affected by nitrogen fertilizer (p<0.01). Nitrogen×plant density interaction also significantly affected all tested traits (p<0.05) except for plant height and siliqua/plant. Our findings suggest that for semi-arid zone of Takestan, Indian mustard due to its high adaptation to arid conditions can be a good option for spring rapeseed replacement.
