EFFECT OF ORGANIC SEED PRIMING ON SEED GROWTH AND YIELD OF DIFFERENT SOYBEAN VARIETIES

Abstract

A pot experiment was conducted at research field-1 of Department of Agronomy Hajee Mohammad Danesh Science and Technology University, Dinajpur-5200 during the period from December, 2023 to May 2024 to study the effect of organic seed priming on yield attributes and yield of the two soybean varieties. The experiment comprised of two factors: A. Two varieties of soybean viz; V1= BARI Soybean-5, V2= BARI Soybean-6, and B. Five seed priming treatments viz P1= (control), P2= (seed priming with 3% Moringa leaf extract), P3 (seed priming with 6% Moringa leaf extract) , P4= (seed priming with 2% aloe vera extract) and P5= (seed priming with 4% Aloe vera extract) were considered as treatments of the experiment. The experiment was layout by completely randomized design (CRD) with three replications it consisted of ten different treatment combinations. Thus, there were 30-unit pots in this experiment. The maximum of growth parameters of soybeans were found statistically significant such as plant height (cm) in different days of interval (20, 40, 60 days after sowing and at harvest), number of branch plant (no.) also at (40, 60 days after sowing and at harvest), number of pods plant (no.), pod length (cm), number of seeds pod (no.), weight of 100-seed (g), seed yield (g plant-1), stover yield (g plant-1) biological yield (g plant-1) and harvest index (%). However considering the varietal characteristics the maximum seed yield (1.77 g plant-1) was observed in BARI Soybean-6 (V2) while minimum (1.51 g plant-1) was produced by BARI Soybean-5 (V1) and also maximum Stover yield (3.56 g plant-1) recorded in BARI Soybean-6 while the minimum was found (3.36 g plant-1) from BARI Soybean-5(V1). In case of different priming treatments, the effect of 6% Moringa leaf extract (P3) generated the maximum seed yield (1.96 g plant-1) whereas no priming (P1) produced the minimum seed yield (1.17 g plant-1). Priming with 2% Aloe vera extract showed the maximum (3.63 g plant-1) stover yield and no priming treatment showed the minimum (3.05 g plant-1) results respectively. In treatment combination, V2P3 generated maximum (2.12 g plant-1) seed yield and stover yield (3.68 g plant-1) whereas the minimum seed yield (1.01 g plant-1) and stover yield (3.00 g plant-1) were recorded from V1P1 treatment combination. So, it may be suggested that BARI Soybean-6 (V2) primed with 6% (P3) showed better result for growth and yield of Soybean.
