EFFECT OF FERTILIZER AND MANURE ON THE NUTRIENT AVAILABILITY AND YIELD OF T. AMAN RICE IN TWO DIFFERENT SOIL

Abstract

The experiment was conducted in a net house of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka during the period from June to November 2013 in aman season to find out effect of fertilizer and manure on the nutrient availability and yield of T. Aman rice in different soil. BRRI dhan33 was used as the test crop in this experiment. The experiment comprised of two factors- Factors A: Soils from two different locations, S1: SAU soil, S2: Shingair soil (collected from Shingair Manikgonj) and Factor B: Levels of fertilizers and manures T0: Control condition i.e. no fertilizers and manures; T1: Recommended dose of fertilizer (N120P25K60S20Zn2), T2: 50% NPKSZn + 5 ton cow dung ha-1, T3: 50% NPKSZn + 5 ton compost ha-1 and T4: 50% NPKSZn + 3.5 ton poultry manure ha-1. The experiment was laid out in a randomized complete block design (RCBD) with three replications. Data were recorded on different growth, yield parameters, nutrient concentration in grain and straw and nutrient status of post harvest soil. Significant variation was observed for different treatment and their interaction effect. For soil from different location, the highest grain yield (101.13 g pot-1) was recorded from S2 and the lowest grain yield (76.21 g pot-1) from S1. The highest N, P, K and S concentration in grain (1.378%, 0.249%, 0.225% and 0.071%, respectively) was recorded from S2, whereas the lowest was found from S1. The highest organic matter (2.45%) was found from S2, while the lowest (1.30%) was recorded from S1. For different fertilizers and manure, the highest grain yield (123.65 g pot-1) was found from T4, while the lowest grain yield (33.70 g pot-1) was obtained from T0. The highest N, P, K and S concentration in grain (1.536%, 0.279%, 0.252% and 0.077%, respectively) was recorded from T4, while the lowest was observed from T0. The highest organic matter (2.11%) was observed from T4, whereas the lowest organic matter (1.61%) was found from T0. The highest post experiment soil. Due to the interaction of soil from different location and fertilizers and manure, the highest grain yield (134.97 g pot-1) was found from S2T4, whereas the lowest grain yield (32.03 g pot-1) was recorded from S1T0. The highest N, P, K and S concentration in grain (1.651%, 0.286%, 0.262% and 0.081%, respectively) was recorded from S2T4 and the lowest was found from S1T0. The highest organic matter (2.56%) was observed from S2T2 and the lowest organic matter (0.99%) was recorded from S1T0. Shingair soil and 50% NPKSZn + 3.5 ton poultry manure ha-1 performed better in relation to yield contributing characters and yield of BRRI dhan33.The level of pH, total N, available P and S of the post experiment soil increased more in the SAU soil with 50% inorganic fertilizer plus 3.5 t poultry manure ha-1. The level of OM increased more in SAU soil the lower container soil than Shingair soil.
