EFFECT OF DROUGHT EPISODES ON YIELD AND BIOCHEMICAL CONTENTS OF RICE (Oryza sativa L. ) ACCESSIONS IN SOKOTO AGRO-CLIMATIC ZONE
Year: 2023
Type: article
Abstract: The study was carried out to evaluate the effects of the drought episodes on days to 50% heading and maturity of different rice (Oryza sativa L.) accessions in Sokoto Agro-climatic zone.A total of fifteen ( 15) upland rice accessions were collected from National Cereal Research Institute (NCRI) Baddegi in Niger State, Nigeria.Field experiment was conducted in Kwalkwalawa village of Wamakko Local Government of Sokoto State.Seeds of selected rice accessions were first raised in nursery bed and 21 days old uniformly germinated seedlings were transplanted in to three plots under different drought episodes which are watered once a week (W1), watered twice a week (W2) and watered everyday or control (W0).The seedlings were raised in a completely randomized block design (CRBD) and replicated three times.The result on yield attributes and biochemical contents all showed significant difference at (P≤0.5) for both stresses and control groups.FARO 21, 26, 66, 45, 47 and 48 showed drought tolerance suggesting genetic variability for drought tolerance while FARO 26, 27, 66 and 45 matured earlier suggesting better performance under drought condition.Thus, early maturing and drought resistance accession should be used by farmers to escape drought.
