Performance of Rapeseed Mustard Varieties Grown Under Different Plant Density

Abstract

A field experiment was conducted to evaluate the effect of variety and different plant densities on growth and yield of rapeseed mustard during Rabi 2011-12 under rainfed conditions at Sher-e-Bangla Agricultural University, Dhaka, Bangladesh. Four varieties (BARI Sarisha-13, BARI Sarisha-15, BARI Sarisha-16 and SAU Sarisha-3) and four plant densities (10, 40, 70 and 100 plants m-2) were applied during the course of study. Results indicated that both variety and plant density has significant effects on growth and seed yield of rapeseed mustard. BARI Sarisha-13 (V1) performed well in terms of Branches plant-1 (6.14), Siliqua plant-1 (126.90), seeds siliqua-1 (25.36) and 1000 seed weight (4.00). Branches plant-1 (6.84) and Siliqua plant-1 (95.04) significantly increased by decreasing plant density due to less competition among plants for moisture, light and nutrients. Maximum seed yield (1.60 t ha-1) was recorded for BARI Sarisha-13 with 70 plants m-2 (V1P3). Thus, it is concluded that BARI Sarisha-13 should be grown at 70 plants m-2 for higher yield output.

Assessment of System of Mustard Intensification (SMI) with Plant Geometry and Age of the Seedlings in Enhancing Growth and Yield Attributes of Mustard (Brassica juncea L.)

“…The minimum dry matter accumulation was recorded in treatment T 1 -Conventional sowing (dibbling) with spacing 45 x 15 cm without gap filling at all the growth stages i.e., at branching initiation (335 kg ha ). Similar results were recorded by Mamun et al [9] and Das et al [10].…”

Performance of Rapeseed and Mustard (Brassica sp.) Varieties/Lines in North-East Region (Sylhet) of Bangladesh

“…Number of branches/plant: Significant variation observed in number of branches/plant from 40 DAS and onwards (Figure 3). At 40 DAS, Improved Tori produced the maximum number (2.0) of branches/plant and continued until harvest (9.57) and it was identical with BARI Sarisha-8, BARI Sarisha-15 which supported by BARI [13] and Mamun et al [14] and they showed that, BARI Sarisha-15 produced 7.45 branches/plant. Whereas, minimum branches/plant produced by the line BC-05117 Y at 60 DAS until harvest.…”

“…They were found maximum number of siliqua/plant (136) in the variety J-5004 which was identical with the variety Improved tori. On the other hand, Mamun et al [14] reported that, BARI Sharisa-15 produced maximum (73.11) siliqua/plant under 40 plants/m 2 . Yadav et al [16]…”

Impact of Row Spacing, Sowing Density and Nitrogen Fertilization on Yield and Quality Traits of chia (Salvia Hispanica L.) Cultivated in southwestern Germany

“…Thousand seed mass was significantly influenced by sowing densities, varying from 1.18 to 1.22 g (p = 0.0125, Table 4). High sowing rates are associated with excessive numbers of plants resulting in severe interplant competition and a reduction in TSM on rapeseed and mustard according to Kayaçetin et al [34] and Mamun et al [41]. The present study showed a similar trend being in line with these findings as the highest TSM was obtained at the lowest sowing density of 1 kg ha −1 while lower TSMs were obtained at sowing densities of 1.5 and 2 kg ha −1 (Table 4).…”
