Effects of Pigeon Pea (<i>Cajanus cajan</i>) Intercropping on Sorghum Crop Production and Soil Fertility Level in Case of Harari Regional State (Erer Research on Station)

The study was conducted during 2019 main cropping season at Erer research station Babile district PA. Globally pigeon pea (Cajanus cajan (L.) Millsp.) is the fifth most important pulse crop mainly grown in developing countries by resource-poor farmers drought prone areas and on degraded soils. It a multipurpose leguminous that can provide food, forage, fuel wood fodder for small-scale farmer subsistence agriculture. Pigeon deep-rooted tolerant grain legume adds substantial amount of organic matter to soil has ability fix up 235 kg N/ha). Harari regional state, didn’t accept sorghum variety, because small harvests total biomass. Thus why, intercropping solve problem low availability forage fertility this land area. treatments experiments were, Sole (malkam) Sorghum + Accession 16520, 16527, +Accession 16528, 16527 16528 respectively. design experiment was, RCBD with three replication. result showed significant difference statistically, terms plant height, panicle length, diameter 5% (table 1). highest height obtained from treatment intercropped accession (tsegas variety). statistically not yield (p < 0.01) among (both sole one). In (Table 1) indicated Accessions had no negative effect yields sorghum. maximum were T3 (sorghumX16527 accession); (2894) ha-1), followed T2 (16527 accession) (2856) ha-1 minimum (2339 ha-1). probable reason variation could be due nature accessions add nitrogen nutrients affect positively. When observed graphically, there mean difference. Both equivalent ratio relative calculated about 1.22. So advantageous. Partial budget analysis economically viable.
