摘要

在西孟加拉邦BCKV项目下的Gayeshpur中央研究农场进行了一项试验,以评估2019-20和2020-21冬季(rabi)季节种植的鼠尾草(Salvia hispanica L.)的生长、产量和品质属性。处理采用分块设计,在主地块采用2种建立方式(M1,直播和M2,移栽),4种种植密度(S1, 60 cm × 50 cm = 33,333株/ha;S2, 50 cm × 50 cm = 40000株/ha;S3, 50 cm × 25 cm = 80,000株/ha;S4, 50 cm × 20 cm = 10万株/公顷)。直播株距较近(50 cm × 20 cm)的一次枝数(15.7个/株)、一次枝长(38.4 cm)和主花序长(25.9 cm)均高于其他处理组合,体现了该处理组合的优势。同一处理组合的籽粒产量(671.7 kg/ hm2)、茎产量(1109.4 kg/ hm2)和果皮产量(375.2 kg/ hm2)均显著提高,收获指数(31.2)显著提高。在总回报(228.4 × 103卢比/公顷)、净回报(166.3 × 103卢比/公顷)和B: C比(3.67)方面,相同处理组合的作物的经济响应最大。根据二次回归方程,计算出奇亚的最佳种植密度为71428株/ha。因此,在西孟加拉邦的rabi季节,直接播种密度为71428株/公顷(间距~ 55 cm × 25 cm)可用于奇亚种植。

Growth , yield and quality of medicinal plant Chia (Salvia hispanica) as influenced by planting methods and density
An experiment was conducted at Central Research Farm, Gayeshpur, Nadia under BCKV, West Bengal to assess the impact of plant density and planting methods on growth, yield and quality attributes of chia (Salvia hispanica L.) grown during winter (rabi) seasons of 2019–20 and 2020–21. Treatments were distributed in split-plot design, with 2 establishment methods (M1, direct sowing and M2, Transplanting) in main plots and 4 planting density (S1, 60 cm × 50 cm = 33,333 plants/ha; S2, 50 cm × 50 cm = 40,000 plants/ha; S3, 50 cm × 25 cm = 80,000 plants/ha; S4, 50 cm × 20 cm = 1,00,000 plants/ha) in sub-plots. Crop under direct sowing with closer spacing (50 cm × 20 cm) had the greater number of primary branch (15.7/plant), primary branch length (38.4 cm) and main inflorescence length (25.9 cm), thereby reflecting superiority of this treatment combination over others. The same treatment combination produced significantly the highest grain (671.7 kg/ha), stem (1109.4 kg/ha) and husk yield (375.2 kg/ha), which led to increase harvest index (31.2). The greatest economic response in terms of gross return (228.4 × 103 ₹/ha), net return (166.3 × 103 ₹/ha) and B: C ratio (3.67) was recorded in crop under the same treatment combination. Based on quadratic regression equation, the optimum plant density of chia was calculated as 71,428 plants/ha. Thus, direct seed sowing at a density of 71,428 plants/ha (spacing ~ 55 cm × 25 cm) can be done for chia cultivation during rabi season in West Bengal condition.
