Cowdung, Poultry manure, Fertilizers, Growth, Yield and Wheat
1) to study the effect of cowdung and poultry manure on growth and yield of wheat
2) to study the effect of fertilizers on the growth, yield and quality of wheat.
3) to study the combined effect of organic manure and fertilizers on the growth and yield of wheat
4) to study the effect of cowdung, poultry manure and fertilizers on the nutrient content and uptake by wheat
5) to study some characteristics of the post harvest soil.
The experiment was conducted at the field laboratory of the department of soil science, Bangladesh Agricultural University (BAU), Mymensingh, during the period from 3rd December 2000 to 25th March 2001 to examine the effects of cowdung, poultry manure and fertilizers (N, P, K, S, Zn and B) on the growth and yield of wheat cv. Kanchan. There were twelve treatments: T0 (control), T1 (Cowdung), T2 (Poultry manure), T3 (NPK), T4 (NPK + Cowdung), T5 (NPK + Poultry manure), T6 (NPKS), T7 (NPKSZn), T8 (NPKSZnB), T9 (NPKS + Poultry manure), T10 (NPKSZn + Poultry manure), T11 (NPKSZnB + Poultry manure). The experiment was laid out in a randomized complete block design with three replications. The rates of different organic manures and fertilizers were 5 t ha-1, Poultry manure 5 t ha-1, 90 kg N ha-1 from urea, 40 kg P2O5 from TSP, 60 kg K2O ha-1 from MP, 20 kg S ha-1 from Gypsum, 3 kg Zn ha-1 from ZnO and 1 kg B ha-1 from Borax. There were 36 (12 × 3) unit plots, each plot measuring 4.0 × 2.5 m2 , plots were separated from each other by a space of 20 cm and block distance 1m. During growing period of wheat, all necessary cares were done for ensuring and maintaining the normal growth and development of the crop. The physical and chemical properties of the soils were reported to be sand 22.84%, silt 70.0%, clay 7.16%, textural class silt loam, pH 7.22, organic matter 1.71%, total N 0.063%, available P 9.44 µg gm-1, available S 13.34 µg gm-1, exchangeable K 0.139 me 100g-1 soil and CEC 10.35 me 100g-1 soil.
