“…Therefore, for onion production, it is very difficult to give general recommendation to be applied uniformly in all agro ecologies of the country (UAAIE, 2001). Gupta et al (1994) and Lemma and Shimeles (2003) suggested that to optimize onion productivity, full package of information is required for each growing region of the country. Similarly, the success of onion production is also depend on soil nutrients.…”

Abstract:The productivity of onion crop is low due to poor agronomic and management practices in Gode district. Therefore, a field experiment was conducted at Gode Polytechnic College demonstration farm in 2013 under irrigation to assess the effect of N fertilizer rates and intra-row spacing on growth parameters of onion (Allium cepa L.). The treatments were consisting of six rates of N fertilizer (0, 46, 69, 92, 115, 138 kg ha -1 ) and four levels of intra-row spacing (7.5, 10, 12.5 and 15 cm) and the experiment was designed in RCBD with three replications. Results of the analysis revealed that the interaction effects of N rates and intra-row spacing showed highly significant (P<0.01) effect on leaf number. Plant maturity was delayed at higher N rates and wider intra-row spacings and vice-versa. The longest plant height was obtained from 15 cm intra-row spacing and 138 kg N ha -1 where as the shortest was recorded from 7.5 cm intra-row spacing without N fertilizer application. Longest leaf length was obtained from plants spaced at 15 cm fertilized with 138 kg N ha -1 . However, the shortest was recorded for plants grown in 7.5 cm intra-row spacings without N fertilizer. The overall result analysis showed thatgood growth performance of onion was obtained from 15 cm intra-row spacing combined with 138 kg N ha -1 fertilizer applications.

“…Young, bleached lesions, typical of A. porri infection in dry conditions, might be confused with those of C. allii-cepae (Ryan, 1978). Gupta et al (1994) have identified Stemphylium blight (S. vesicarium) and purple blotch (A. porri) as diseases of national importance, whereas, Colletotrichum blight was found to be localized in Maharashtra.…”
