| dc.description.abstract | Maize is produced throughout the world and it is also a primary staple food crop in many developing countries. The field experiment was conducted during the rainy season of 2018 G.C in Burie district to study effects of types and growth stages of seedlings on growth and yield of transplanted maize (Zea mays L.). Factorial combinations of two types of seedlings (bare rooted and poly bagged); five levels of seedling’s growth stages (seedlings of 1, 2, 3, 4 and 5 true leaf/ves) and one control (direct seeded) were laid down in randomized complete block design with three replications. Data on phenological, vegetative growth and yield related parameters were collected following standard methods and procedures. All data were subjected to analysis of variance using SAS software; and mean separation for significant treatments were done by LSD. Both main effects affected number of grains cob-1, grain and stover yield highly significantly and days to 50% siliking very highly significantly. Types of seedlings affected days to 50% tasseling significantly; and days to 90% physiological maturity and plant height highly significantly. In addition, types of seedlings affected number of cobs plant-1, cob length, number of grains row-1and biomass yield, very highly significantly. Seedlings growth stages had very highly significant effect on days to 50% tasseling and days to 90% physiological maturity. Number of cobs plant-1, cob length, number of grains row-1and biomass yield were also highly significantly affected by seedlings growth stages. The interaction effect was highly significant on number of cobs plant-1, grain and stover yield and very highly significant on harvest index. The highest (10.7t ha-1) grain yield of maize was found from transplantation of poly bagged seedlings at four true leaf stage. Although it is difficult to conclude based on one season and one location research trial, transplanting of poly bagged seedlings at four true leaf stage gave superior grain yield. This treatment combination also gave the highest net benefit with acceptable range of marginal rate of return. Therefore, transplanting of poly bagged seedlings at four true leaf stage is economically feasible and can be recommended tentatively for Burie District. However; it’s also advised to repeat the study in areas having terminal moisture stress for maize production. Keywords: Bare root; Growth stage; Poly bagged; Seedling; Transplanting Chapter 1.
