Abstract/ Executive Summary:

The experiment was carried out at the Department of Animal Nutrition, Bangladesh Agricultural University, Mymensingh, to study the effects of different doses of nitrogen (N) fertilizer on yields and chemical composition of Zamboo grass. The fodder was cultivated at 4 levels of N fertilizer viz., 0, 50, 100 and 150 kg urea ha^-1 in a completely randomized design having four replications in each treatment. The unit plot size of each replicate was 4x4 m. The fodder was harvested at the pre flowering stage (68 days after sowing) for first cutting and again 40 days after first cutting. The proximate components of the fodder for each plot were determined at the laboratory, Department of Animal Nutrition. The results of the study showed that the total yields (t ha^-1) of Zamboo grass on fresh basis were 11.08, 15.63, 22.35 and 26.72 in the first cuttings and 7.94, 12.24, 16.65 and 22.41 in the second cutting using 0, 50, 100 and 150 kg urea ha^-1, respectively. The total dry matter (DM) yield of fodder for first cutting at the treatment levels of 0, 50, 100 and 150 kg urea ha^-1 were found to be 1.85, 2.75, 3.66 and 4.60 t ha^-1 and those in second cutting were 0.67,2.13, 3.08 and 3.97 t ha^-1, respectively. Total yields of fodder green as well as DM basis in both cutting progressively and significantly increased with the increasing levels ofN fertilizer doses. Similarly crude protein (CP), crude fiber (CF) and ether extract (EE) yields (t ha^-1) were increased with increasing fertilizer doses. The green fodder as well as DM yields and percent of different proximate components of each treatment were higher in the first cutting than that of the second cutting except CF. The DM percent of the fodder was almost similar for different fertilizer treatments in both cutting. Among the various proximate components, CP, CF and EE percent increased by increased ing the N fertilizer doses while ash percentage decreased.

Objectives:

To study the effects of N fertilizer doses on yields and chemical composition of Zamboo grass.

Methodology:

The experiment was conducted at the Animal Nutrition field laboratory of the Department of Animal Nutrition, Bangladesh Agricultural University, Mymensingh during the period from May 1999 to September 1999. The experiment was conducted in completely randomized design (CRD) comprised 4 nitrogen (N) levels viz., 0, 50, 100 and 150 kg urea ha^-1. Each treatment was replicated four times. Size of each experimental plot was 4x4 m. Phosphorus fertilizer (P₂O₅) in form of triple super phosphate (TSP) and murate of potash (MP) was applied at a rate of 50 kg ha^-1 during land preparation. Fifty percent of the required N fertilizer of different doses was applied before sowing in the form of urea and remaining fifty percent was applied after 5 weeks of sowing as top dressing. All the plots received a basal dose of 20 q ha^-1 of cow dung. The seeds were sown in rows by line sowing method maintaining the distance of 25cm and 5cm for row to row and plant to plant, respectively. The seed rate was 50 kg ha^-1. Weeding was done once during the experimental period. No irrigation and insecticides were used. Zamboo grass in each plot was harvested at the pre flowering stage (68 days after sowing) and green fodder yield was recorded. Each plot was kept for further growing of fodder. After 45 days of first cutting, the fodder was harvested again and fodder yield was recorded at fresh basis. During first and second harvesting, the representative samples of Zamboo grass were collected at random from each treatment plot. After collection they were tagged separately and kept for further processing. At the same time freshly collected five representative plants from each plot was chopped into small pieces and kept for determining dry matter (DM) content of the fodder. Samples of the whole plant of Zamboo grass for different treatments were subjected to chemical analysis for the determination of crude protein (CP), crude fiber (CF), ether extract (EE) and total ash contents following the methods of AOAC. Data were analyzed using MSTAT-C statistical program for a completely randomized design and differences among the treatment means were determined by the least significant difference method.

Achievement/Findings:

On the basis of the results of the present experiment, it may be concluded that the production of Zamboo grasses both in first cutting (harvested at 68 days of age) and second cutting (45 days after first cutting) was highest through application of 150 kg urea ha^-1. In addition to that the nutrient content of Zamboo grass was also increased with the increasing levels of N fertilizer except ash content. Therefore, 150 kg urea ha^-1 may be recommended as optimum dose for zamboo grass production under Bangladesh condition.
