Some Agricultural Practices to Improve the Productivity of Cabbage Under Sinai Conditions

Abstract

The experiments were conducted to investigate the effect of compost rates and foliar spray with biohorm and chitosan on growth, yield and chemical composition of two cabbage varieties grown under sandy soil. Os cross cv. had the highest values of number of leaves /plant, head diameter, head weight, the percentage of dry matter and yield as compared with Nabrawy. Compost application enhanced growth parameters and yield. The highest values were obtained with 8 and 6 ton/fed. Also, chitosan treatment significantly increased head weight and diameter, number of leaves/plant and yield. As for chemical composition, Nabarawy cv. had the highest K content. Compost application at rate of 6 ton/fed increased N and K contents. Chitosan treatment showed significant increase of N, while biohorm treatment gave the highest K, Fe and Cu contents. A linear correlation showed that average of head weight was positively correlated with both head diameter and number of leaves per head. Also, total yield was positively correlated with head weight, head diameter and number of leaves per plant. In general, it might be concluded that Os cross proved to be a high yielded cultivar as compared with Nabarawy. In addition, compost application at rate of both 8 and 6 ton/fed, gave the highest total yield. Moreover, yield of cabbage plant sprayed with chitosan had the highest values.

Growth and Productivity of Two Cabbage Cultivars Grown in Sandy Soil as Affected by Foliar Spray with Npk Fertilizer and Amino Acids

“…The interaction between OS Cross cultivar and spraying with amino acids at 3 ml/l and NPK (15-15-15) fertilizer at 2 ml / l gave the highest values of head yield / plant and total head yield /fad., followed by the interaction between OS Cross cultivar and spraying with amino acids at 1.5 ml/l and NPK (15-15-15) fertilizer at 1 ml / l. in both seasons. Total yield of cabbage (ton/fed) was highly significant positively correlated with either head weight (kg),head diameter (cm) or number of head leaves (El Sagan , 2014) The yield of cabbage attributes were significantly influenced by fertilizer types and variety (Olaniyi and Ojetayo ,2011) . The application of NPK (15-15-15) fertilizer significantly increased the cabbage head yield compared to control (Moyin-Jesu1,2015) Amino acids are a well-known stimulant which has positive effects on plant growth, yield and significantly mitigates the injuries caused by abiotic stresses.…”

“…OS Cross had the highest leaf / plant number, head diameter, head weight, dry matter percentage and yield compared to Nabrawy cultivar (El Sagan, 2014) Being a powerful root system, the cabbage extracts vast quantities of nutrients that go into head formation. Cultivation of cod plants therefore requires high soil fertility with good fertilization and foliar spray with NPK fertilizers.…”
