GROWTH AND YIELD PERFORMANCE OF MUSTARD AND RAPESEED VARIETIES AS INFLUENCED BY DIFFERENT SOWING TECHNIQUES

Abstract

An experiment was done at the Agronomy field laboratory, Sher-e-Bangla Agricultural University, Dhaka during the period from Robi, 2013-14 to investigate the growth and yield performance of mustard and rapeseed varieties as influenced by different sowing techniques. The experiment was laid out in two factors Randomized Complete Block Design (RCBD) with three replications. There were 16 treatments (4 variety × 4 sowing technique). The variety treatments were V1= BARI Sarisha-11, V2= BARI Sarisha-13, V3= BARI Sarisha-15, V4= SAU Sarisha 2. Sowing technique treatments were S1= Broadcasting, S2= Line Sowing, S3= Raised Bed, S4= System of Mustard Intensification (SMI). Results showed that highest plant height (143.58 cm) was achieved at the combination of BARI Sarisha-11 and raised bed technique. Highest dry matter (39.93 g) was produced by the combination of BARI Sarisha-11 and SMI technique. Highest number of siliquae plant-1 (1179.67) was achieved at the BARI Sarisha-11 and SMI technique. Maximum siliqua length (8.99) and seeds siliqua-1 (30.33) was achieved with the combination of BARI Sarisha-13 and SMI technique. Highest grain yield (4.75 t ha-1) and biological yield (16.06 t ha-1) were obtained by the combination of BARI Sarisha-11 and SMI technique. Maximum harvest index (36.45%) was obtained at the combination of BARI Sarisha-15 and SMI technique. Highest weight of 1000-seed (4.26 g) was found at the combination of BARI Sarisha-11 and raised bed technique. Highest oil percentage (41.73%) was obtained from the plots with the combination of BARI Sarisha-15 and line sowing technique.
