Abstract

This study was carried out during 2011, 2012 and 2013 for producing vegetable sprouts and vegetable crops using different growing media in wooden plot. The wooden plot located in the kitchen experimental farm module in the vegetables experimental farm of the Faculty of Agriculture, Ain Shams University, to develop a rapid and simple method that could be used in homes or developed for commercial production of sprouts with increased emphasis on the nutritive value of foods and especially the so-called fresh natural foods, this study was also designed to determine the nutritive value of turnip, radish and onion sprouts produced in four growing media. Green sprouts could be of value as a fresh low cost vegetable grown in the kitchen garden in any seasons and could contribute vitamins and other nutrients to the diet. The second purpose to produce vegetable crops in four growing media in the winter season (Turnip, red radish and green onion) and followed by jews mallow and snap bean crop in the summer season and determine the nutritional value of plants. And also, to increase the flat green urban areas of the dampening impact on the climate and reduce air temperatures.
The study includes three parts with the following obtained summary results:
Part one: Vegetables sprout production
For the production of green sprouts of turnip, red radish and onion, 1 m2 wooden plot filled with different growing media was used. To study the effect of growing media on the green sprouts of turnip, red radish and onion, separate experiments with four growing media (treatments) were adopts (Clay, clay + vermiculate 1:1 v/v +10% compost, sand + vermiculate 1:1 v/v + 10% compost and peatmose + vermiculate 1:1 v/v). The experiment was set in completely randomized block design with three replicates. Sprouts were harvested at fully expanded green cotyledons stage (7 days for turnip and 8 days for red radish from seed sowing, while onion bud sprouts were harvested 3 weeks after sets sowing). The obtained results could be summarized as follows:
A. Turnip sprouts
1. Turnip sprouts grown in peatmoss + vermiculite medium showed the longest hypocotyle length, while clay medium recoded the best cotyledon dimensions; sprout fresh weight and fresh yield of sprouts per m2 and per unit volume of seeds (1.0g) of turnip seeds sprouts.
2. The turnip sprouts produced in clay medium presented marked increase in the content of protein, energy Kcal/g protein, phenols, flavonoids, flavon, free amino acids, indoles, nitrogen, potassium and calcium on a dry weight basis as compared to other media. On the contrary, the content of lipid in turnip sprouts decreased in clay medium.
3. Turnip sprouts produced in clay mixture medium had a higher content of carbohydrates, energy Kcal/g carbohydrates and vitamin C than sprouts produced in other media.
4. Turnip sprouts produced in sand mixture medium gave a higher content of chlorophyll a, chlorophyll b, total chlorophyll, carotonoids, total energy, sodium, iron and magnesium than sprouts produced in other media.
5. The content of energy Kcal/g lipids, total sugars, total soluble sugars and anthocyanin in turnip sprouts recorded the higher value in sprouts produced in peatmoss + vermiculite medium.
B. Red radish sprouts
1. Peatmoss + vermiculite medium recorded the higher cotyledon dimension, sprout fresh weight and fresh yield for red radish sprouts per m2 and per unit volume of seeds.
2. The content of chlorophyll a , total chlorophyll, ash , energy Kcal/g protein, nitrogen, sodium and magnesium increased in red radish sprouts grown in sand mixture medium as compared to other media
3. The red radish sprouts grown in clay medium presented marked increase in the content of chlorophyll b and protein. On the other hand, the percentage of lipid decreased in sprouts grown in clay medium compared with other media.
4. Red radish sprouts grown in clay mixture medium gave the higher content of carotonoids, carbohydrates, total energy, energy Kcal / g carbohydrates, energy Kcal/g lipids, anthocyanin, vitamin C, phosphorus, potassium, calcium and iron as compared to other media.
5. The content of total sugars , total soluble sugars, phenols, flavonoids , flavon , free amino acids and indoles recorded the higher values in red radish sprouts grown in peatmoss + vermiculite medium on a dry weight basis.
C. Onion bud sprouts
1. Onion bud sprout length, green top, white base length, white base diameter, number of leaves, fresh weight (g) and fresh yield weight (kg/m2 and g/kg of bulbs) significantly increased in sprouts grown in peatmoss + vermiculite medium as compared to other media.
2. Onion bud sprouts for 3 weeks old showed the highest value of chlorophyll a, chlorophyll b, total chlorophyll, phenols, flavon and sodium were obtained in sand mixture medium compared with other media.
3. The content of protein, fiber, energy Kcal/g protein, total sugars, free amino acids, nitrogen and magnesium showed the highest value in onion bud sprouts grown in clay mixture medium on a dry weight basis compared with other media.
4. The higher value of carbohydrates, total energy, energy Kcal/g carbohydrates, energy Kcal/g lipid, flavonoids, anthocyanin and potassium recorded in onion sprouts grown in peatmoss + vermiculite medium as compared to other media.
5. Onion bud sprouts grown in clay medium had a higher content of carotonoids, ash, vitamin C and iron as compared to other media. On the contrary, the percentage of lipid in onion sprouts declined in clay medium on a dry weight basis.
The clay mixture medium can be recommended for producing turnip and red radish sprouts or clay medium alone. However, the harvested seed sprouts from peatmoss medium showed peat residues between sprouts radical with difficulty to remove and clean the sprouts. Therefore, the clay mixture medium can be recommended for producing turnip and red radish sprouts at cotyledon stage using seedling rate at 30 g/m2 for turnip and 60 g/m2 for red radish. On the contrary, peatmoss + vermiculite medium can be recommended for producing onion bud sprouts for 3 weeks.

Part three: Subsequent jews mallow and snap bean crop production in the summer season.
One square meter wooden plot filled with different growing media was used to produce jews mallow plant on 19th March after harvesting green onion plant, while snap bean plant production in two square meter wooden plot after harvesting turnip and red radish plants. Each wooden plot was filled with each medium under investigation. To study the effect of growing media on subsequent jews mallow and snap bean crops in the summer season.Separate experiments with four growing media (Clay, clay + vermiculate 1:1 v/v +10 % compost, sand + vermiculate1:1 v/v + 10 % compost and peatmose + vermiculate1:1 v/v). The experiment was set in completely randomized block design with three replicates.

from the previous results it can be generally concluded that the clay media can be recommended for producing jews mallow plants, but it could be change clay medium because it’s fertility is decreased with using for multi times in kitchen garden. On the contrary, peatmoss + vermiculate medium can be recommended for producing snap bean plant in the kitchen garden or roof garden
