Agronomic performance of seven pea (Pisum sativum) genotypes with five sowing dates in sandy soil

Abstract

A field experiment was conducted at the Agriculture Faculty Farm of Sebha University during the 2007/2008 and 2008/2009 winter seasons to study the agronomic performance of seven pea genotypes with different sowing dates in sandy soil. The experiment was laid out in a randomized complete block design (RCBD) using a split-plot arrangement with three replicates. The five sowing dates (30 October, 15 November, 30 November, 15 December and 30 December) were assigned to the main plots, while the seven pea genotypes (Ambassador, Pollon, MG130256, G22765-2c, 89-P-109-11, No. 252, Victory Freezer and Master B) were allocated to the sub-plots. The sowing dates had a significant effect on all the studied traits except seed protein content in both seasons. Early sowing (15 November) was better than the other sowing dates for all the traits except 100-seed weight. There were significant differences between the pea genotypes for all the traits in the two growing seasons. The Victory Freezer genotype surpassed the other genotypes for all traits except number of branches plant-1 in the second season, 100-seed weight and seed protein content. The highest values for number of branches plant−1 in the second season and for seed protein content were obtained for the G22765-2c genotype, while the maximum values of 100-seed weight were recorded for the MG130256 genotype. A significant interaction between sowing dates and pea genotypes was detected for the length of the period from emergence to initial flowering, number of pods plant−1, seed yield plant−1 and seed yield ha-1 in both seasons. The longest period from emergence to initial flowering was obtained for the Victory Freezer pea variety sown on 30 November, while the highest values of pods plant−1, seed yield plant−1 and seed yield ha−1 were gained by sowing the Victory Freezer pea genotype on 15 November.

Influence of Date of Sowing on Growth and Yield Performance of Field Pea (Pisum sativum L.) Genotypes

“…Higher yield due to the exposure of plants in favorable environmental condition during reproductive stages because it gave highest number of pods and seeds plant -1 . These results are similar with the findings of Hanaa and Ali (2000) [13] where they reported that seed yield of field pea varied among the interaction of variety and sowing date due to variation in number of pods and seeds plant -1 .…”

Impact of Irrigation Water Deficit and Foliar Application with Salicylic Acid on the Productivity of Two Cowpea Cultivars

“…Azmirly cultivar surpassed the Cream 7 in this respect by 40.62 and 30.09 % in the first and second season, respectively. This may be due to the genotypic, environmental interaction (Hanaa and Ali, 2011) .All the interactions involved in this respect were not significant in both seasons.…”

Morphological Characterization and Selection for High Yielding and Powdery Mildew Resistant Pea (Pisum sativum) Lines

“…The plants were planted in November and harvested in April at University of Malakand, Khyber Pakhtunkhwa, Pakistan located at coordinates N 34° 40" 318' and E72° 03" 753' at altitude 726 m. The 24 lines were grown in a layout of complete randomized block design with three replicates in row plots as suggested by Hanaa and Ali (2011). The length of each plot was 18 m with a width of 3 m. Each line was planted in a row plot with 75 cm row to row in distance and 10 cm plant to plant in distance (Nisar et al 2011).…”
