Abstract

Salinity is a serious environmental issue that reduces the yield of vegetable crops. Brinjal is one of the world's most popular vegetable crops and its productivity and quality are heavily influenced by the salt content in the root area. Plant growth regulator management, however, is a key factor that can be used to increase brinjal production in moderate saline soils. The experiment was carried out at the Agricultural Research Field, Noakhali Science and Technology University, Noakhali, Bangladesh during the period from January to June 2022, to observe the effect of plant growth regulators on growth, yield, and yield contributing characters of brinjal (Solanum melongena L. V: Purple king ). The experiment was followed Randomized Complete Block Design (RCBD) comprising four treatments with three replications. The treatments were T0 (Control), T1 (Salicylic acid @ 60 ppm), T2 (Gibberellic acid @ 60 ppm), T3 (Naphthalene acetic acid @ 60 ppm). Data were recorded from different stages of plant growth viz, plant height, number of leaves per plant, number of branches per plant, number of fruits per plant, fruit length, fruit diameter, fruit weight, and yield. The maximum plant height (100.00 cm), number of leaves per plant (197.17) , number of branches per plant (17.17), number of flowers per plant (62.67), number of fruits per plant (34.42), fruit length (25.50 cm), fruit diameter (3.33 cm), weight of fruit (92.67 g), yield per hectare (22.17 t ha-1) were measured from treatment T2 (GA3 @ 60 ppm). Results conclude that the application of gibberellic acid @ 60 ppm for brinjal cultivation gave better growth and yield in moderate saline soils. Res. Agric. Livest. Fish.

植物生长调节剂对孟加拉沿海地区茄子生长、产量及产量贡献特性的影响

盐碱化是一个严重的环境问题，它降低了蔬菜作物的产量。茄子是世界上最受欢迎的蔬菜作物之一，其产量和质量受到根部含盐量的严重影响。然而，植物生长调节剂管理是可用于增加中等盐碱地茄子产量的关键因素。试验于2022年1 - 6月在孟加拉国Noakhali Noakhali科技大学农业研究试验场进行，观察植物生长调节剂对茄子(Solanum melongena l.v: Purple king)生长、产量及产量贡献特性的影响。试验采用随机完全区组设计(RCBD)， 4个处理，3个重复。处理为T0(对照)、T1(水杨酸@ 60 ppm)、T2(赤霉素酸@ 60 ppm)、T3(萘乙酸@ 60 ppm)。记录植物生长的不同阶段的数据，即株高、单株叶数、单株枝数、单株果数、果长、果径、果重和产量。从T2 (GA3 @ 60 ppm)处理开始，测定了最大株高(100.00 cm)、单株叶数(197.17)、单株枝数(17.17)、单株花数(62.67)、单株果数(34.42)、果长(25.50 cm)、果径(3.33 cm)、果重(92.67 g)、每公顷产量(22.17 t ha-1)。结果表明，在中等盐碱地中施用60 ppm的赤霉素酸对茄子生长和产量有较好的促进作用。阿格利司》。力所能及的。鱼。第10卷第2期，2023年8月:91-97
