EFFECT OF POULTRY MANURE AND NPK FERTILIZERS ON THE GROWTH AND YIELD OF WHEAT (BARI Gom 26)

Abstract

An experiment was conducted at central research field of Hajee Mohammad Danesh Science and Technology University, Dinajpur during the period of October 2016 to March 2017 in order to investigate the effects of different levels of nitrogen (N) phosphorus (P) potasium (K) and poultry manure (PM) on the yield and yield contributing characteristics of wheat (BARI Gom 26) in the design of Randomized Complete Block Design (RCBD). Five fertilizer treatments were used and which were T1 = PM0(NPK)0, T2 = PM0(NPK)100, T3 = PM100(NPK)0, T4 = PM100(NPK)50, T5 = PM100(NPK)33. The experimental results revealed that plant height, spike length, number of tillers hill-1, number of spikelet’s spike-1, 1000- grain weight, straw weight, grain weight were significantly influenced by PM and NPK fertilizers. The highest plant height (96.95cm) was observed in T4 treatment and the lowest (74.80cm) was found in the control. The maximum number of tillers (10.25) was produced in the treatment T4 and minimum number (3.75) was found in the control. The highest number of grain (57.42) was found in the treatment T4 which was statistically identical. The lowest number of grain (20.40) was observed in the control treatment. Grain yield and straw yield of wheat plants were significantly influenced with the application of PM along with NPK fertilizers. It was found that the application of NPK fertilizers at 75-70-50 kg ha-1 with 8 t PM ha-1 produced the highest grain (5.24 t ha-1) and straw (4.95 t ha-1) yield. The control treatment produced the lowest grain (3.08 t ha-1) and straw (3.15 t ha-1) yield. The findings of the study showed that the performance of the treatment T4 was the best among the other treatments in respects of plant height, tillers hill-1, number of grain spike-1, spike length, grain yield and straw yield of wheat. Therefore, the overall results indicate that the application of NPK fertilizers at 75-70-50 kg ha-1 with 8 t PM ha-1 can be more efficient and economic for wheat production.
