Abstract

The study was undertaken to evaluate the efficacy of NPK briquette for increasing the yield of jhum rice. Two experiments were conducted at Ramery para, Bandarban sadar, Bandarban hill district in Chittagong under the AEZ 29 (Northern and Eastern Hills Tract) during March 2017 to November 2017 to study the effect of NPK briquette on growth and development of Jhum rice. In this experiment, Jhum rice was used as the test crop. The experiment was conducted in two field and designed on Randomized Completely Block Design (RCBD). The treatments consisted of 7(seven) levels of NPK briquette i.e. T1: Control, T2: 100% RFD (267.5 kg ha-1), T3: 120% RFD (320.8 kg ha-1), T4: 80% RFD (214.1 kg ha-1), T5: 100% NPK briquette (267.5 kg ha-1), T6: 120% NPK briquette (320.8 kg ha-1), T7: 80% NPK briquette (214.1 kg ha-1). Ratio in 100 kg NPK briquette contain 50 kg urea: 30 kg TSP: 20 kg MoP and RFD value was N 60 kgha-1, P 20 kg ha-1 and K 30 kg ha-1. The growth and yield of Jhum rice were significantly influenced by different levels of NPK briquette. The highest plant height of jhum rice (138.3 cm), effective tillers hill-1 (16.03), panicle length (30.10 cm), highest number of filled grain panicle-1 (202.8), 1000 grain weight (27.67 gm), straw yield (4.13 t/ha) and grain yield (3.54 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). Yield of Jhum rice mainly vary with RFD and NPK briquette but highest yield obtained from NPK briquette treatment compared with control.
