Effect of Farm Yard Manure, Gypsum and Nitrogen on Growth and Yield of Rice in Saline Soil of Satkhira District, Bangladesh

Abstract

A field experiment was conducted at the sub-station farm of Bangladesh Institute of Nuclear Agriculture (BINA), Satkhira, to observe the effect of Farm yard manure (FYM), Gypsum and Nitrogen levels on growth and yield of rice (cv. Binadhan-8). The experiment was laid out in a RCBD split-plot design with three replications. Treatments consisted of five FYM and Gypsum combinations in main plot, which were S 0 : The study revealed that different FYM and Gypsum combinations along with different N levels have significant effect on growth and yield of rice. Mean effect of FYM and Gypsum combinations found the highest for grain (3.69 tha 1) and straw (6.60 tha-1) yield where plot received FYM @ 5 tha-1 +Gypsum 210 kgha-1. Considering the mean effect of different N levels, when the plant received 125 kg Nha-1 then the maximum grain and straw yield of rice were observed as 3.81 and 6.91tha-1 , respectively. Due to the interaction effect of both FYM and Gypsum combinations and N levels, the maximum grain yield of rice was found as 4.39 tha-1 under the treatment combination of S 2 N 4 , i.e., FYM @ 5 tha-1 and Gypsum 210 kgha-1 along with 125 kg Nha-1 .
