Improving of vitamins C and D3 content of medicinal pumpkin plant grown under organic farming programs

Abstract

This study aimed to evaluate the application of different farming programs. Three organic farming (P2, P3, P3) were used and compared with traditional programs (P1, chemical). Their effect in improving medicinal pumpkin seeds quality was examined. As a quality addition of supplying chain, the quantitative and qualitative content of vitamins C and D3 were assayed. This plant seeds are considered of healthy and medical importance, and have their marketing placement. A big amount of the seeds have been consumed directly by human year round. Using the seeds in food production processes increased their nutritional value. The field experiment was conducted on two dates. The design used was the randomized complete block design. All data were collected and analyzed according to ANOVA table using Duncan’s multiple range test at P= 0.05. The results obtained showed significant distinguish of the organic farming program (P3) compared to the rest the programs used. This treatment had significant increase of vitamins C and D3 content in the seeds in the two dates (0.0883 mg l-1, 0.08671 mg l-1, 12.38 mg l-1 and 12.32 mg l-1 respectively). The other two organic programs (P2, P4) were significantly distinct compared to the traditional one (P1). The study concluded that these studied organic programs can be an effective choice to improve seed quality of this crop. The healthy and nutritional value are enhanced, and the side effects of traditional agriculture on the environment are reduced
