Response of Pearl Millet - Guar Mixture to Farmyard Manure Fertilzation under Calcareous Soil Conditions

TWO FIELD experiments were performed at Mariut Research Station, Desert Research Centre (DRC) during 2006 and 2007 growing seasons to study the effect of organic manure levels viz. 0, 10 and 20 m7fed and the effect of five cropping patterns, i.e. Millet pure stand. Guar pure stand and millet/ guar (3:1). (2:2) and (1:3) patternes on some growth parameters, forage yield and chemical composition.Results can be summarized as follow:1.Increasing organic manure significantly increased number of tillers and leaves of millet plants. Moreover increased plant height, number of branches and number of leaves of guar plants. Fresh and dry yield of each pearl millet or guar plants significantly increased due to increasing organic manure as well as the accumulated yield.2.Growing pearl millet with guar plants significantly increased number of leaves of guar plants than sole cropping while the increase of millet growth not reach to significant level under intercropping. Fresh and dry yield of millet insignificantly increased under cropping compared to sole cropping. While the reverse was for guar plants which decreased. Total mixtures as well as accumulated yield were increased.3.Organic manure significantly decreased crude fiber percentage mixture while the reverse was for ash content of plants. Guar plants surpassed millet and other intercropping in its content of crude protein, crude fiber and ash content comaring to sole millet or different intercropping.4.Interaction effect was superior for total fresh and dry yield under 20 m3/fed.
