RESPONSE OF BORON AND SULFUR FERTILIZATION ON MORPHO-PHYSIOLOGICAL, YIELD AND YIELD ATTRIBUTES OF MUSTARD

Abstract

A field experiment was conducted at the farm of Sher-e-Bangla Agricultural University, Dhaka, during the period from November, 2019 to February, 2020 to study the response of boron and sulfur fertilization on morpho-physiological, yield and yield attributes of mustard. The experiment considered of nine treatment, which are consisted of boron and sulfur viz. T 0 = B 0 S 0 , T 1 = 1 Kg B ha 1 S, T 5 = 1 Kg ha -1 B + 20 Kg ha -1 -1 , T 2 = 2 Kg ha S, T 6 = 1 Kg ha -1 -1 B, T 3 = 20Kg ha B + 40 Kg ha -1 -1 S, T 4 = 40 Kg ha S, T 7 = 2 Kg ha B + 20 Kg ha -1 S and T 8 = 2 Kg ha -1 B + 40 Kg ha -1 S. NPK was used in optimum rate in the field (Urea = 350 Kg ha -1 , TSP = 220 Kg ha -1 , MOP = 100 Kg ha -1 ). We used Bari Shorisha-14 (B. campestris). The experiment was laid out in a Randomized Complete Block Design with three replications. The data were collected on plant height, number of leaves per plant, number of branch per plant, SPAD value of leaf, silique per plant, seed per silique, 1000 seed weight, seed yield, stover yield, biological yield, harvest index. A statistically significant variation was recorded in terms of all the characters related to growth and yield of mustard. In the experimental findings we found that, the highest plant height at 30, 45 and 60 DAS (52.37, 97.40 and 113.0 cm), maximum leaf number (16.07), highest number of branch per plant (10.07), maximum SPAD value of leaf (52.63), highest number of siliquae (137), maximum number of seeds siliqua (34.17), highest weight of 1000 of seeds (3.90 g), highest grain yield (1.64 t ha -1 ), highest stover yield (3.97 t ha -1 ), highest biological yield (5.62 t ha -1 ) and highest harvest index (29.20%) were obtained from the combination of 1 Kg B ha -1 + 20 Kg S ha (T 5 ). Therefore, it can be said, that the higher grain yield could be obtained from a combination of 1 Kg ha

-1 B + 20 Kg ha -1 S with NPK
