The effect of harvesting methods on the yield in some broccoli varieties

In order to research the effect of harvesting methods on the yield in some broccoli varieties, four varieties as: V(1) (Shogun F(1)); V(2) (Pirate F(1)); V(3) (Sultan F(1)); and V(4) (Marathon F(1)) and three sowing times as: July, August and September were used in the study. For single harvest, the weight of primary shoots and for continuous harvest; besides the primary shoot weight, the weight and quantity of secondary shoot and the length of the plant were also marked. As a result, while the effect of varieties and characteristics of the plant were not, the sowing time was significant on harvesting methods. The weights of primary and secondary shoots, the number of secondary shoots and plant length were significant in continuous harvesting for which the yield changed between 550.17 - 68.34 g plant(-1). However, the weight of primary shoot was significant in single harvest where the yield varied between 526.11 - 68.21 g plant(-1). Total yield varied between 3,173.8 - 24,356.7 kg ha(-1) in the single harvest and between 3,163.8 - 25,470.6 kg ha(-1) in the continuous harvest. The head diameters and harvest times showed uniformity though their effects were low in the single harvest. Although the yield was high in the continuous harvest, approaching to the end of harvest the observation of decreasing marketable product quality and the requirement of more labour and time in the harvest stated that the single harvest would be preferred

Influence of different sowing times on mineral composition and vitamin C of some broccoli (Brassica oleracea var. Italica) cultivars

Broccoli has a significant position in Cruciferea family through the vitamin C and mineral nutrients it contains. Vitamin C and mineral content in vegetables vary depending upon different sowing times. In this study, the change of vitamin C and minerals was examined in 3 different sowing times "July the 1st (ST1), August the 1st (ST2) and September the 1st (ST3)" for 4 broccoli cultivars "CV1 (cv Shogun F1), CV2 (cv Pirate F1), CV3 (cv Marathon F1) and CV4 (cv Sultan F1)". The vitamin C content ranged in between 52.6 g 100 g-1 and 32.4 g 100 g-1 for broccoli cultivars grown in different sowing times. CV3 (cv Marathon F1) had the highest vitamin C content and the late season (ST3) had higher vitamin C content than the early seasons (ST1, ST2). It was observed that different sowing times for broccoli cultivars did not affect P, Mn, Cu, and Zn contents significantly, however, the heads of the broccoli cultivars had been affected significantly for different sowing times in N, K, Ca, Mg, and Fe. In broccoli heads, N mineral content varied between 4.01 to 2.60% and attained its highest values in sowing times of ST2 (August) and ST3 (September). K content in broccoli heads was highest in ST3 (September) sowing time and varied from 3.96 and 2.21%. Ca content was highest in ST1 (July) and value varied from 1.58 to 0.80%. The highest Mg content was for ST3 (September) sowing time and its value altered from 0.18 to 0.46%. Fe content was highest in ST1 (July) sowing time and its content varied between 100.23 and 96.14 ppm. © 2011 Academic Journals

Seasonal variations versus some quality parameters: Garden nasturtium (Tropaeolum majus L.)'s leaves

This research aims to detect the variations in quality of garden nasturtium's leaves in following growing seasons. Research was conducted out in greenhouse for the late summer-early autumn (August, September, October) and the late springsummer (May, June, July) growing period in Turkey (40097' N, 27051' E). Results presented subsequent morphological properties for the leaves: area (61.36 mm2), length (28.27 mm), average width (2.37 mm), maximum width (3.97 mm), thickness (0.40 mm), mass (93.63 g) and moisture (0.90% w.b.) were found greater in values for the late spring-summer than the late summer-early autumn season. The season affects the dry matter ingredients, which were greater in the late spring-summer than late summer-early autumn growing season. It was 11.49% in the late summer-early autumn and 13.27% in the late spring-summer growing period. Protein content of the plants for the late summer-early autumn (26.39%) was greater than the late spring-summer (21.19%) growing period. Sowing time decision significantly affects ascorbic acid ingredient which was 43.29 mg.100-1g in the late summer-early autumn and 38.65 mg.100-1g in the late spring-summer growing period. The values for the terms L, a, and b were assessed as 20.70; -6.41; and 7.79 in the late summer-early autumn and 28.54; -7.23; and 8.52 for the late spring-summer period respectively. Sowing time significantly affects color properties ingredient as well and the record for the late spring-summer was found higher than the late summer-early autumn growing time. Mineral ingredients were measured as N (4.73%), P (0.67%), Ca (2.38%), Cu (10.24 ppm), Fe (971.36 ppm), and Zn (59.98 ppm) and these values were higher in the late summer-early autumn period, however, K (4.49%), Mg (0.46%), and Mn (63.28 ppm) ingredients were higher in the late springsummer period. The findings reflected that changing weather conditions also affect garden nasturtium. Owing to its relatively easy growing conditions and nutritive value, it provides a good alternative product for the late spring-summer period in greenhouses. © by PS
