Abstract

An experiment was carried out to study the use of compost and farmyard manure on Zamboo grass production. The forage was cultivated at 3 levels of each of the compost and .organic manure viz. 10, 12, 14 ton/ha in a completely randomized design having three replication in each treatment designated as TO, Ti, T2, and T3 respectively. The unit plot size of each replication was 4 m x 2.5 m. Plant height of the forage was measured every fortnightly. The grass was harvested at the pre flowering stage (60 days after sowing) and its yield and nutrient composition were determined. The results of the study showed that height of the plant significantly (P <0.01) increased with increasing doses of either of the compost or organic manure at each of 15, 30, 45 and 60 days after sowing (DAS). The results also showed that green biomass yields (MT/ha) of Zamboo grass were 22.07, 24.33, 28.33 and 30.17 for the effect of compost and 22.00, 23.67, 26.67 and 29.00 for the effect of farmyard manure. The total DM yield (MT/ha) of the forage for the use of compost at To, T1, T2 and T3 treatments were found 4.64, 5.11, 6.26 and 6.34 and for farmyard manure were found 4.64, 5.21, 5.38 and 6.34 respectively. The proximate analysis showed that the average dry matter content of Zamboo forage at different levels of compost was: 21.1, 22.01, 21.8, and 21.97 in treatments To, Ti T2 and T3 respectively. Crude protein content of the grass at different level of doses were 8.40, 8.60, 9.80 and 9.20 (g/100 g DM) in response to 0, 10, 12 and 14 ton/ha, respectively. The crude fiber content influenced significantly (P<0.01) with higher doses of FYM. Use of compost at the rate of 14 ton/ha gave the highest (34.00%) CF content while the treatment with 14 ton/ha farmyard manure gave the lowest (30.20%)CF content. Highest value (1.41) of ether extract (EE) was found in treatment with 14 ton compost/ha. From the present study it could be concluded that Zamboo grass harvested at 60 days of age through application of 14 ton compost/ha was better for the production of biomass and nutrient content.
