Abstract/ Executive Summary:

Sunhemp was cultivated to evaluate it as a fodder crop and found that the plant height of green dry matter increased significantly (P<0.0011 to 160 cms and 66.4 tons/hectare and 11.8 tons/h respectively at 60 days from 40.6 cms and 9.39 tons/h and 1.22 tons/h respectively at 30 days of growth. Similarly, the significant (P < 0.0 11 increase was found in the level of structural carbohydrate components such as crude fibre, acid and neutral detergent fibre, and hemicellulose from 172, 236, 149 and 87 g.kg-1 respectively at 30 days of growth to 379, 543, 377 and 166 g.kg-1 dry matter respectively at 60 days of growth. But the level of crude protein and nitrogen free extract decreased significantly (P<0.011 at 87.0 and 457 g.kg-1 at 60 days from 162 and 559 g.kg-1 respectively at 30 days of age. Digestibility of organic matter and digestible and metabolizable (DE and ME, MJ kg-1 dry matter) energy content were insignificant in variation among the harvesting times. Sunhemp, as fodder crop may be harvested at 60 days of growth for higher yield of nutrients but further research on animal performance may confirm the results.

Keywords: Sunhemp, Yield, Nutritive value

Location: Animal Nutrition Department, BAU, Mymensingh

End Date:

Program Area: Crop-Soil-Water Management

Commodity: Sunhemp

Objectives:

To determine the yield composition, organic matter digestibility in vitro and energy content at different stages of maturity of sumhemp.

Methodology:

The experiment was conducted in two phases. In the first phase sunhemp was cultivated in the fodder research plot of Animal Nutrition Department, BAU, Mymensingh and its yield at different stages of maturity was determined. The digestibility and energy estimations in vitro were done in the Animal Nutrition Laboratory, BAU, Mymensingh. Cultivation: Sunhemp seeds were collected from Tangail District. Land was prepared after ploughing for 4 times and divided into nine experimental plots having three plots for each of the growth period. Each experimental plots was 9 sq.m in size. Seeds were broadcasted at the rate of 22.5 kg/ha. No fertilizer was applied. Collection and Analysis of Samples: The samples were collected at three stages of maturity ego at 30, 45 and 60 days of age. In each stage of maturity, fresh yield, dry matter (dm) and crude protein (cp) yield and chemical composition of the whole plant, leaves and stems were determined. Chemical analyses were done according to AOAC (1965). Digestibility: The determination of digestibility in vitro of organic matter, metabolizable and digestible energy content were performed using the In Vitro Technique of Menke et al., (1979).

Achievement/Findings:

From the above results it may be stated that sunhemp at 60 days of age may be harvested for higher quantity of nutrients. But further work on the voluntary intake of dry matter in animals and digestibility in vitro of nutrients at different ages of maturity is essential to determine.
