COMPARATIVE STUDY OF USG AND NPK BRIQUETTE ON THE PERFORMANCE OF JHUM RICE

Abstract

Two experiments were conducted at Ramery para, Bandarban sadar, Bandarban, Bangladesh hill district in Chittagong under the AEZ (Agro Ecological Zone) 29 (Northern and Eastern Hills Tract) during March 2017 to November 2017 to study of USG and NPK briquette on the performance of Jhum rice. The experiment was conducted in two field and designed on Randomized Completely Block Design (RCBD). The treatments consisted of 7(seven) levels of USG (Urea Super Granule) and NPK briquette i.e. T1: Control, T2: 100% USG and PK (RFD) (267.5 kg ha-1), T3: 80% USG and PK (RFD) (214.1 kg ha-1), T4: 80% USG and PK (RFD) (320.8 kg ha-1), T5 :100%NPK briquette (267.5 kg ha-1), T6: 80% NPK briquette (214.1 kg ha-1), T7: 120% NPK briquette (320.8 kg ha-1). The growth and yield of Jhum rice were significantly influenced by different levels of USG and NPK briquette. The highest plant height of jhum rice (139.23 cm), effective tillers hill-1 (16.60), panicle length (30.23 cm), highest number of filled grain panicle-1 (245.23), 1000 grain weight (28.0 gm), straw yield (4.15 t/ha) and grain yield (3.56 t/ha) were found from T5 treatment receiving 100%NPK briquette (267.5 kg ha-1) and for all cases lowest results were found in T1 treatment receiving no fertilizer (control).
