Effect of Diammonium Phosphate on Some Cultivars of Maize (Zea mays L.) as forage crop

Abstract

This study was conducted at the demonstration farm of the faculty of agricultural studies (shambat), during late winter season 7106, separated in to two experiments in different location; to study effect of DAP fertilizer on growth and yield of three cultivars of maize as forage crop. The experiment was laid out in Randomized Complete Block Design (RCBD) with split plot arrangement having three replications. The maize cultivars are: (heddaba0, heddaba7, var. 002) were treated with (without DAP/ha, 71kg DAP/ha, 41kg DAP/ha, 61kg DAP/ha). The seed were sown in the field with three seeds inplot. 7×7 M7for the plot, and in pot 1.2 M7, The distance between the plants were 21CM. Parameters studied were: plant height, stem diameter, number of leaves, fresh and dry weight, also protein and fiber percentage. The results showed non significant differences among the all parameters, in both experiments.
