Abstract/ Executive Summary:

The experiment was conducted to study the comparison on biomass production of fodder germplasm. Para (Bra ch ierie mutica Stapf.). German (Echinochloa crusgalli L.) and Dhal (Hymenachne pseudointerrupta C. Muell) grasses were cultivated in a completely randomized design (CRD). The whole area was divided into nine plots. The area of each unit plot was 6 m x 6 m. Number of cuttings were 16,000 /hectare where Plant to Plant distance was 16 cm and row and raw distance was 16 cm. Equal amount of organic and chemical fertilizer were applied in all cutting. The fodders were first harvested after 60 days of planting, second and third after successive 60 days of re-growth. The findings of the study showed that fresh biomass (p<.01 ) and dry biomass yield (p<.05) of three fodder gramplasm different significantly.Crude protein and organic matter yield were significant (p<.01) only in the second cutting. However, no significantly effect on plant height was observed among three grasses. From the above findings it may be concluded that among the three fodder germplasm, German foder showed best result in respect of biomass production.

Objectives:

To compare the biomass production of three fodder germplasms.

Methodology:

The climate of the experimental site was characterized by scanty rain and higher temperature during the whole experimental period. The experimental site was in the old Brahmaputra Flood Plain Aqro-ecoloqical zone having non-calcareous dark, gray flood plain. The soil was silt loam texture, neutral in reaction (pH 7.0) and contained 0.12% N, 0.07% P and 1.76% organic matter. The experiment was laid out in a Completely Randomized Design (CRD) with three replications in each treatment. There were nine experimental plots having each area of 36 m²with a distance of 0.15m from plot to plot. The land was prepared by ploughing and cross ploughing four times with bullock-drawn country plough. Lengths of cuttings were 16-18 cm and contain at least 3 nodes in its sheath. Cutting of grasses were planted by line sowing keeping one node under the soil with 450 angles and maintaining a row and plant spacing of 16 cm with a cutting rate of 16,000 cuttings per hectare. At the time of land preparation 130 t/ha cow dung was applied. After 22 days of planting cow dung was applied at the rate of 52 kg/plot. After 30 days of first cutting, cow dung was applied at the rate of 52 kg/plot with 0.25kg of urea. Again after 30 days of 2nd cutting, 52kg of cow dung and 0.35kg of urea were applied per plot. Fertilizer doses were applied in broadcasting methods. Intercultural operations were done as and when necessary. Three representatives samples (long medium and short), from each category were cut down before harvesting. Plant height was measured using measuring tape and weights of the plants were taken. Fodders were harvested above the ground level (3-5 cm) after 60 days of planting. Green biomass yield from each plot was recorded with the weighing balance. After 60 days of 1st cutting, the fodder was harvested at 60 days interval and fresh biomass yield was also recorded. Then third time fodder was harvested after 60 days of 2nd cutting and fresh biomass yield was recorded. The data were analyzed using the "MSTAT" statistical program in a Completely Randomized Design, and differences among the treatment means were determined by the Least Significant Difference method.

Achievement/Findings:

In considering biomass production of three fodder germplasm, it may be suggested that German, Para and Dhal fodder is suitable for animal production but German fodder is more suitable among the three fodder germplasms.
