Yield and yield components of wheat as influenced by intercropping of oilseed rape and fertilizers
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2013, Vol 3, Issue 6
Abstract
A field experiment was carried out at Research Farm of Tabriz University, Tabriz, Iran, over consecutive 2 winter seasons (2010-2012) in order to study the profitability of wheat (Triticum aestivum L.) and oilseed rape (Brassica napus L.) intercropping under 2 types of fertilizer. A sole crop of wheat (A1) was compared with 8:3 (A2), 12:4 (A3) and 16:5 (A4) row proportions of wheat-oilseed rape intercropping systems under 100% chemical fertilizers and 50% chemical fertilizers + biofertilizers. The results showed that grain yield increased by 22.25, 25.38 and 13.72 percent over sole crop of wheat in case of intercropping of wheat-oilseed rape at 8:3, 12:4 and 16:5 rows, respectively. The 12:4 rows combination gave significantly higher number of spike/m2 (611.6), grain yield (610.3 g/m2) and biological yield (1353.0 g/m2) than that of sole wheat (513.4, 455.3 g/m2and 1072.7 g/m2, respectively). According to measured traits, A2 and A3 had no statistically significant difference and so sole crop of wheat had the lowest value for all of studied traits. In 2010-2011, spike length and grain umber per spike were more than those of 2011-2012, while the number of spike per plant and per unit area, 1000 grain weight and harvest index were greater in 2011-2012. Treatment 100% chemical fertilizer had significantly higher grain yield (575.8 g/m2) and biological yield (1301.7 g/m2) than that of 50% chemical fertilizer + biological fertilizers. Therefore, it was concluded that strip intercropping of wheat and oilseed rape in 8:3, and 12:4 row ratio had the maximum yield components that it led to increase grain yield.
