Performance of Radish in Aonla based Multistoried Agroforestry System

Abstract

An experiment was conducted in a 19-years old aonla orchard from October 2019 to January 2020 at the Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU) research farm to determine the performance of different radish varieties in aonla based multistoried agroforestry systems. The study consisted of two factors viz. four agroforestry systems (aonla + carambola, aonla + lemon, aonla only, and open field) and four radish varieties (BU mula-1, BARI Mula-1, BARI Mula-2 and Rocky 45) laid out in a two factorial randomized complete block design with three replications. Findings exhibited that light availability in the open field was 727.02 µmol m-2s-1 which was significantly higher over the aonla based multistoried agroforestry systems. Light received by the aonla + lemon, aonla, and aonla + carambola systems were 74.13, 65.57, and 52.77% of the open field, respectively. The highest (276.47 g) leaf fresh weight produced by Rocky 45 was noticed in aonla + carambola system and the lowest leaf weight produced by BU mula-1 was found in an open field. The highest root fresh weight (592 g) was produced by Rocky 45 in the open field, and the lowest root fresh weight (102.60 g) was produced by BU mula-1 in aonla + carambola based system. The highest root yield (39.47 t/ha) of Rocky 45 was produced in an open field and a higher leaf yield (18.43 t/ha) was reported in BU mula-1 among four radish varieties. Among four radish varieties, Rocky 45 performed better yield in open field conditions and aonla based agroforestry system.
