Seed treatment has as its main feature the prevention of pest entry in cultivated areas, besides being of great importance in the development of vigorous and healthy plants. The objective of this work was to evaluate the performance of corn genotypes with biostimulant in seed treatment under water stress environment. The experimental design was randomized blocks in a 3x3 factorial scheme, corresponding to three corn genotypes (P3707, P30S31 and P30F35) and three seed treatments with the biostimulants (ConrSeeds, Stimulate and Água). The experiment was carried out at Luiz Eduardo de Oliveira Sales Experimental Farm, located in the municipality of Mineiros, Goiás, from March 2018 to August 2018. Plant height, stem diameter, ear insertion height, number of rows per ear, number of grains per row, number of grains per ear and yield were evaluated. The obtained data was submitted to the assumptions of the statistical model, verifying the normality and homogeneity of the residual variances, as well as the additivity of the model, testing univariate and multivariate analyzes. Analysis of variance revealed significance only for the main genotype effect. Seed treatments did not improve yield components of corn genotypes. The genotypes differed, where the variables number of rows per ear, number of grains per row and number of grains per ear directly influenced the grain yield.

This study was carried out to investigate the effects of different sowing times on duration of tasselling, plant height, first ear height, ear length, ear diameter, number of ears per plant, fresh ear yield with husk, fresh ear yield unhusked, and marketable number of ears of different sweet corn (Zea mays L. saccharata Sturt.) varieties in Diyarbakır between the years of 2010-2012. The trial was conducted as split plots in randomised complete blocks with three replications. The main plots were sowing times, and the sub-plots were varieties. The trials were carried out at eight different sowing times (1 April, 15 April, 1 May, 15 May, 1 June, 15 June, 1 July and 15 July) with ‘Merit’, ‘Jubilee’, ‘Lumina’, ‘Vega’ and ‘Sakarya’ composite sweet corn varieties. From the variance analysis of the three-year combined average, the duration of tasselling, plant height, first ear height, ear length, ear diameter, number of ears per plant, fresh husked ear yield, fresh unhusked ear yield and marketable ear number were statistically significant for sowing times and varieties. According to the sowing time × variety interaction, except ears per plant and first ear height values, all other traits were significant. The fresh husked and unhusked ear yields varied between 8541.7-19396.8 kg ha-1 and 5065.0-13485.7 kg ha-1, respectively. The highest fresh husked and fresh unhusked ear yields were obtained from the 15 April sowing time of ‘Vega’ variety. The results state that optimal sowing dates for different varieties of sweet corn could be from 1 April to 1 May, and the most suitable variety to be planted is ‘Vega’ in Diyarbakır conditions.

Effect On Yield

An experiment was conducted to evaluate effect of urea fertilizer on yield and yield components of Zea mays L. Using Randomized Complete Block Design (RCBD) split plots in three replications in agricultural research farm of Balkh University by 2019. Doses of urea used in this experiment were 0, 80, 160 and 240 kg ha-1 , respectively. It has been found that amount of nitrogen fertilizer (urea) had significant effect on yield of maize at p<0.05. The higher level of nitrogen caused the higher grain yield, number of kernels per ear, the number of grains per ear row, ear diameter, cob length, grain per plant and plant height. As a result 7.76 ton ha-1 was recorded as high yield while 240 kg ha-1 urea was used, and 5.12 ton ha-1 was recorded as low yield in treatment one with 0 kg ha-1 of nitrogen fertilizer. Finally, as a result using 240 kg ha-1 nitrogen fertilizer is recommended.
