Water Productivity of Sunflower under Different Irrigation Regimes at Gezira Clay Soil, Sudan - Eman Rahamtalla Ahmed Elsheikh - Bog - Taylor &

The Gezira Scheme is Sudan''s oldest and largest gravity irrigation system. The scheme has played an important role in the economic development of the country, and is a major source of foreign exchange. The farming system of the Gezira Scheme is dominated by crop production. The main crops grown are sorghum, wheat, groundnut and the oilseed crop sesame. Sunflower ( Helianthus annuus L. ) is an important oil crop in the world and a new edible oil crop in Sudan. Knowledge of the effects of irrigation scheduling on sunflower production and water productivity under water stress conditions is becoming increasingly important. Irrigation scheduling is particularly important since many field crops are more sensitive to water deficit at specific phonological stages. Sunflower has several growth stages: emergence, vegetative, reproductive, flowering, seed formation and maturity. Water stress in each stage results in reduction in seed yield and oil content. The treatments in the test plots, which were conducted to study the effect of water stress at different growth stages, showed that sunflower was significantly affected by water stress that occurred in the sensitive flowering and seed formation stages. Highest seed yield was obtained when water stress was avoided during these stages. The AquaCrop model was used to simulate the seed yield and water productivity. The model was able to precisely simulate seed yield, but overestimated water productivity under different irrigation treatments.

Heterosis and Hybrid Seed Production in Agronomic Crops - - Bog - Taylor & Francis Inc - Plusbog.dk

Heterosis and Hybrid Seed Production in Agronomic Crops discusses how heterosis or “hybrid vigor” has played a major role in improving crop productivity and quality in order to feed the ever-increasing human population, particularly in developing countries. Plant breeders, agronomists, seed producers, and farmers will discover why the development of hybrids in the world''s major food crops and why the methods of hybrid seed production are critical for achieving this goal. This landmark book deals with heterosis and hybrid seed production of major agronomic crops such as wheat, rice, maize, sorghum, cotton, sunflower, and rapeseed. Through Heterosis and Hybrid Seed Production in Agronomic Crops, you will discover valuable information on hybrid seed production methods that is not available in any other single volume. This unique book contains relevant and essential information about important procedures to help increase crop yield, including: - methods for deriving second cycle inbred lines for hybrid maize - possibilities for hybrid seed production in wheat - techniques of hybrid sorghum seed production - production of hybrid seeds using male sterile lines of cotton - agronomic management in seed production plots of sunflower - seed production technology of hybrid rapeseed - - advances in hybrid seed production technology of rice in China Heterosis and Hybrid Seed Production in Agronomic Crops gives you a global perspective on essential food crops in all parts of the world. This informative guide will help you use hybrid seed production methods with important agricultural crops and increase the quality of these vital and essential food sources.
