    EFFECTS OF DIFFERENT SOURCES OF PHOSPHORUS ON THE GROWTH AND YIELD OF BRRI DHAN29
    (BANGLADESH JOURNAL OF PROGRESSIVE SCIENCE & TECHNOLOGY, 2014-07) Robbani, MG; Hoque, MA; Huda, A; Bir, MSH; Haque, MM; Uddin, MJ
    An experiment was carried out at Mymensingh during the period from February to June 2011 to study the effects of different sources of phosphorus on the growth and yield of BRRI dhan29. The experiment was designed with six treatments and laid out in a Randomized Complete Block Design (RCBD) with three replications. The treatment combinations were TO: control (No P), T1 : 100% P from Triple super phosphate (TSP), T2 : 100% P from Di ammonium phosphate (DAP), T3 : 100% P from compost, T4 : 50% P from TSP + 50% P from compost T5 : 50% P from DAP + 50% P from compost. All the plots received P from different sources @ 25 kg ha-1 except control. Application of different sources of P resulted in a significant increase in yield contributing characters of BRRI dhan29. The effect of DAP was more pronounced than that of TSP or compost. Application of P also significantly increased the grain and straw yields of rice. The highest grain (5.19 ha-1) and straw (7.11 t ha-1) yields were observed by the addition of P from DAP while the lowest grain (3.95 t ha -1) and straw (4.20 t ha-1) yields were observed in control treatment where no P fertilizers were added. Results also indicate that application of DAP caused a remarkable increase in grain and straw yields of rice. Application of P from different sources led to an increase in NPKS contents and uptake by rice. In most cases, DAP resulted in a higher nutrient uptake by rice crop. DAP can be used as a better source of P fertilizer compared to TSP or compost for rice cultivation in Bangladesh.
