Abstract

In Burkina Faso, the sesame sector is still relatively unorganized, with poor quality seeds that are unsuitable or outdated farming practices and noncompliant with recommended technical itineraries. This situation is very worrying and needs to be rectified. For this reason, we undertook this study to highlight the impact of the seeding method on the physiological, morphological, and agronomic performances of sesame (Sesamum indicum L.) varieties grown in Burkina Faso. The experiment was conducted at the Gampèla agropedagogical station located at 12°25′N, 12°22′W from Ouagadougou. Varieties S-42, 32-15, Wollega, and Humera were grown in strips (broadcast seeding) and in randomized complete blocks (row sowing). Row seeding favored plant growth and development for all varieties. Seed yield per plant for row seeding was significantly ( P < 0.001 ) higher than for broadcast seeding. In terms of 1000 seed weight, there was a decrease in the Wollega variety (2.42 g) in the broadcast seeding group compared with the row seeding group (3.13 g). The seeding method had no effect on the other varieties. The seeding method also had no significant influence on the lipid and protein contents of the seeds. When sown in rows, varieties S-42 (25.7 g/kg), 32-15 (20.64 g/kg), and Wollega (17.33 g/kg) accumulated more K than the broadcast seeding groups. For the Humera variety, the seeding method had no effect on K. Na accumulation in leaves was statistically equal for all varieties in both broadcast and row seeding. Variety 32-15 accumulated more Mg when sown broadcast (5.95 g/kg) than when sown in rows (3.85 g/kg). On the other hand, the varieties S-42 (3.13 g/kg), Wollega (4.21 g/kg), and Humera (3.12 g/kg) accumulated less Mg when broadcast than when sown in rows (S-42 (4.37 g/kg), Wollega (5.68 g/kg), and Humera (5.73 g/kg)). Thus, seeding in rows is recommended to obtain better vegetative development and higher capsule and seed yields for all varieties. Both of the seeding methods deliver the same lipid, protein, and Na contents for all varieties. Broadcast seeding is recommended for better Mg content for variety 32-15, and row seeding is recommended for better K content for varieties S-42, Wollega, and 32-15.
播种法对芝麻生理、农艺和生化性能的影响在布基纳法索种植的品种
在布基纳法索,芝麻行业仍然相对缺乏组织,质量低劣的种子不适合或过时的耕作方法,也不符合推荐的技术路线。这种情况非常令人担忧,需要加以纠正。出于这个原因,我们进行了这项研究,以强调播种方法对生长在布基纳法索的芝麻(Sesamum indicum L.)品种的生理、形态和农艺性能的影响。实验在距瓦加杜古12°25′n, 12°22′w的gamp拉农业教学站进行。品种S-42、32-15、Wollega和Humera采用条播(撒播)和随机整块(行播)种植。行播有利于所有品种的生长发育。行播单株种子产量显著高于撒播(P < 0.001)。千粒重方面,播播组沃勒加品种(2.42 g)比行播组(3.13 g)减少;播种法对其他品种没有影响。播种法对种子的脂肪和蛋白质含量也无显著影响。行播时,品种S-42 (25.7 g/kg)、32-15 (20.64 g/kg)和Wollega (17.33 g/kg)积累钾量高于撒播组。对于Humera品种,播种法对k - Na在叶片中的积累量没有影响,在播种法和行播法中,所有品种的k - Na积累量在统计学上是相等的。品种32-15撒播的Mg积累量(5.95 g/kg)高于行播(3.85 g/kg)。另一方面,S-42 (3.13 g/kg)、沃勒格(4.21 g/kg)和Humera (3.12 g/kg)撒播时的Mg积累量低于S-42 (4.37 g/kg)、沃勒格(5.68 g/kg)和Humera (5.73 g/kg)。因此,建议对所有品种进行行播,以获得更好的营养发育和更高的蒴果和种子产量。两种播种方法对所有品种提供相同的脂质、蛋白质和钠含量。32-15建议采用撒播方式,以提高Mg含量;S-42、Wollega和32-15建议采用行播方式,以提高K含量。
