EFFECT OF ORGANIC AND INORGANIC SEED PRIMING OF CHICKPEA

Abstract

A field experiment was conducted at the research field of Department of Agronomy, Hajee Mohammad Danesh Science and Technology University, Dinajpur-5200 during the period from November, 2019 to April, 2020 to study the effect of organic and inorganic seed priming on the chickpea varieties. The experiment was laid out in randomized complete block design with three replications. The experiment consists of two factors; namely: Factor A: Three varieties of chickpea viz. V1= BARI Chola-5, V2= BARI Chola-9, and V3= BARI Chola-10 and Factor B: Three priming treatments viz. P1=No priming (Control), P2= Inorganic priming (CaCO3:5% calcium carbonate) and P3= Organic priming (Neem leaf extract). The experiment was laid out in two factorial Randomized Complete Bloke Design (RCBD) with three replications, thus there were 27 (9×3) unit plot in this experiment. The size of the plot was (1.0 × 1.0) m2. Observations were statistically significant results of most of parameters of chickpea as plant height (15, 30, 45, 60 (DAS) and at harvest), number of branches plant-1 (15, 30, 45, 60 DAS and at harvest), number of pods plant 1 (no.), pod length (cm), number of seeds pod-1 (no.), weight of 1000-seed weight (g), seed yield (t ha-1), straw yield (t ha-1), biological yield (t ha-1) and harvest index (%). However, considering the varietal characteristics, the maximum grain yield (1.41 t ha-1) was observed in BARI Chola-10 (V3) and that of minimum grain yield (1.27 t ha-1) was produced by BARI Chola-5 (V1) and also maximum straw yield (2.39 t ha-1) recorded in BARI Chola-10 (V3) while minimum was found straw yield (2.15 t ha-1) from BARI Chola-5 (V1). In case of different priming treatments, P2=Inorganic priming with 5% CaCO3 generated the maximum grain yield (1.41 t ha-1) whereas control produced the minimum grain yield (1.27 t ha-1) No priming (p1) and the organic priming treatments (p3) showed the highest (2.32 t ha-1) and the lowest straw yield (2.27 t ha-1) respectively. In combination V3P2 generated maximum grain yield (1.41 t ha-1) and straw yield (2.46 t ha-1) whereas the minimum grain yield (1.27 t ha-1) and straw yield (2.14 t ha-1) were recorded from V1P1 treatment combination. So, it may be suggested that BARI Chola-10 (V3) variety with inorganic priming with 5% CaCO3(P2) better for growth and yield of chickpea.
