EFFECT OF VARIOUS ORGANIC NUTRIENT SOURCES AND SHADING MATERIALS ON THE GROWTH AND YIELD OF CORIANDER (Coriandrum sativum L.) LEAVES

Abstract

The field experiment was conducted at the Horticulture farm of Sher-eBangla Agricultural University, Dhaka from May 2022 to July 2022 to find

the effect of various organic nutrient sources and shading materials on the

growth and yield of coriander leaves. The experiment included two factors

(Shading

materials and Organic nutrient sources). There were Four Shading materials (S 0 - Open, S 1 - Cloth shade, S - White polythene shade and S 3 2 – Natural shading) and Four Organic nutrient sources (G - Control, G 1 - Biochar 5 t/ha + vermicompost 1.75 t/ha, G -Vermicompost 3.75 t/ha and G 3 2 - Biochar 2.5 t/ha + vermicompost 2.63 t/ha. Three replications were used in the randomized complete block design of the experiment. It was found that, among all of the shading materials, shading material S

showed the highest foliage output, and shading material S showed the lowest foliage yield. On the other hand, the highest yield was identified at organic nutrient sources G , whereas the lowest foliage output was identified at organic nutrient sources G 1 . It was observed that the combination of Biochar 5 t/ha + vermicompost 1.75 t/ha) with cloth shade gave better performance in respect of foliage yield among all the combination.
