This study was conducted in gedarif research station farm for two seasons in 201 1 and 2012. The objective was to find the relationship among genotypes yield from dry matter and rain fall amount and distribution. The results showed significant differences for the five types of maize at two parameters. This was indicated by number of leaves and dry weight. The results showed highly significant differences between the two species and the rest of the other on the both season 2011 and 2012. The study concluded that, maize varity and genotype can be used as indicators for plant yield and biomass as proved in the crop of the study. The study recommended that varity Hudiba I and Hudiba 2 can be used as practical mean to assess utilization level as expressed by growth performance indicators including dry matter and biomass from maize varity forage crop.
Maize is genetically and phenotypically diverse. In populations containing only a small proportion of the variation present in the entirety of maize, progress based on phenotypic selection is being realized. This is exemplified by consistent gains in hybrid yields [
In Sudan, maize has been known and grown for a long time in small scale, at different locations under rain fed, flood and irrigation conditions. It is less popular as food; hence it receives little attention as potential food crop. Maize had a lower priority in the agricultural development plans due to a number of factors including low yield potential, limited local use, lack of endurable for long period of storage and low market price. They have opinion that the lake lines adapt to a high yield potential of good resistance to pressure as main factors limiting the production of main maze in some African countries.
The rain fall is the main factor that limits maize production in Gedarif State (
The experiment was conducted under rain fed condition at Gedarif Research Station farm, where laid out randomized complete block design (RCBD) four replications. The experimental plot consisted of 5 ridges each 5 m long spaced 0.75 m Sowing method and planting density: 2 seeds placed in holes spaced at 20 cm on one side of the ridge.
Nitrogen fertilization: Urea, 98 kg/fedan added Three weeks after sowing date. Before sowing seeds were treated with gaucho. Sowing date was at (15/July). The experiments were weeded twice, after two weeks, and four weeks from sowing. Two seasons, 2011 and 2012.
Data analysis: M-stat statistical software Package will be used. Data of herbaceous plant variables will be arranged in randomized completely block design (RCBD) in factorial experiment (four range sites × 3 season).
Duncan multiple range test will be used for means separation.
Data for vegetation measurement will be assessed using standard range measurements equations (
