EFFECT OF SEED PRIMING ON GROWTH, YIELD COMPONENTS AND YIELD OF LENTIL (Lens culinaris)

Abstract

The experiment was conducted to assess the “Effect of seed priming on growth, yield components, and yield of lentil (Lens culinaris) at the Agronomy Research Field of Hajee Mohammad Danesh Science and Technology University, Dinajpur during the period from November, 2018 to March, 2019. The experiment comprised four levels seed priming and two varieties of lentil. The experiment was laid out in Randomized Complete Block Design (Factorial) with three replications. Each block was divided into 8 plots where 8 treatment combinations were allotted at random. The treatments were designed with two factors i. verities; V1= BARI Masur-7, V2= BARI Masur-8 and ii. Seed priming; P1= Normal seed (Control), P2= Hydro priming (DW), P3= Halo priming (KNO3:1% solution of potassium nitrate), P4= Hormonal priming (4% solution of mannitol). Both seed priming and varieties had significant effect on plant height (cm), branches plant1 number of pods plant-1, number of seeds pod-1, pod length (cm), weight of 1000-seeds, seed yield (t ha-1), biological yield (t ha-1) and harvest index (%) except stover yield (t ha-1). Results revealed that verities had significant effect on yield attributes and yield of lentil. BARI Masur-8 gave maximum pods plant-1 (54.23), 1000-seeds weight (21.93 g), seed yield (1.86t ha-1) as well as harvest index (44.68 %). In case of seed priming, significant variations were observed in yield attributes and yield of lentil P3 (1% KNO3) gave higher pods plant-1 (57.61), 1000-seeds weight (22.15 g), seed yield (2.08 t ha-1) and harvest index (46.89 %). P3 had 27.60 % higher yield than P1 (1.63 t ha-1) which was minimum yield. Interaction effects of verities and seed priming were significantly influenced all most parameters of yield attributes and yield of lentil. The interaction effect of V2P3 (BARI Masur-8 and priming with 1% KNO3) where maximum pods plant-1 (61.11), seeds pod-1 (1.82),1000-seeds weight (22.74 g), harvest index (47.66 %) as well as seed yield (2.14 t ha-1) were recorded. V2P3 had 32.09% increased seed yield over V1P1 which gave significantly minimum seed yield (1.62t ha-1).
