EFFECT OF SULPHUR AND POULTRY MANURE ON THE GROWTH AND YIELD OF BORO RICE (BRRI Dhan29)

Abstract

An experiment was conducted at the Soil Science Research Field of Hajee Mohammad Danesh Science and Technology University, Dinajpur during the period of December 2016 to April 2017 in order to investigate the effects of sulphur (S) and poultry manure (PM) on the growth and yield of boro rice (BRRI Dhan29). Six different levels of sulphur and poultry manure were used as treatment viz. T0 = 0 kg S + 0 t PM ha-1, T1 =9 kgha-1 S + 0 t PM ha-1, T2 = 6.75 kgha-1 S + 1.5 t PM ha-1, T3 = 4.5 kgha-1 S + 3 t PM ha-1 , T4= 2.25 kgha-1 S + 4.5 t PM ha-1, T5= 0 kgha-1 S + 6 t PM ha-1. The experimental results revealed that plant height, 1000-seeds weight, unfilled grain, grain yield, straw yield were significantly influenced by S and PM. The highest plant height (91.67cm) was observed in T3 treatment and the lowest (83.57cm) was found in the control. The maximum number of tillers (15.45) was produced in the treatment T3 and minimum number of tiller (12.20) was found in the treatment T0. The highest number of filled grain (156.9) was found in the treatment T3 which was statistically identical with other treatments T0, T1, T2, T4, T5. The lowest number of filled grain (134) was observed in the control treatment. The maximum unfilled grain (30.48) was obtained in T5 treatment which was statistically different from other treatments and the minimum (18.88) was in T3 treatment. The 1000-grain weight (23.40) was highest in T3 treatment and lowest (21.65) in control treatment. Grain yield and straw yield of rice plants were significantly influenced with the application of S along with PM. It was found that the application of 4.5 kgha-1 S ha-1 and 4 t PM ha-1 produced the highest grain (9.40 t ha-1) and straw yield (14.38 t ha-1). The control treatment produced the lowest grain and straw yield. The findings of the study showed that the performance of the treatment T3 was the best among other treatments in respects of plant height, number of tiller hill-1, panicle length, grain yield and straw yield of rice. Therefore, 4.5 kgha-1 S ha-1 and 4 t PM ha-1 may be suggested for the better growth and yield of rice cultivation.
