ਕਣਕ 'ਚ ਇਸ ਖਾਦ ਦੇ ਚਮਤਕਾਰੀ Result ਦੇਖਕੇ ਤੁਸੀਂ ਹੈਰਾਨ ਹੋਜੋਗੇ • How to increase wheat yield
Magnesium sulphate is a secondary nutrient and is used to correct magnesium deficiency in the soil. Magnesium sulphate also improves nitrogen and phosphorous uptake by crops. It is best for crops that required magnesium-rich soil for growth, it is also widely used in pot mixes too.
Magnesium is an important fertilizer element in plant nutrition. Pot experiment was conducted at the greenhouse of the Micronutrients Project, Department of Fertilization Technology, National Research Centre, Dokki, Cairo, Egypt with wheat (Triticum aestivum L.) variety Sakha 93 grown on loamy sand soil to asses the plant response to magnesium sulphate as soil amendment and foliar fertilization. The experiment followed the Complete Randomized Block Design (CRBD) and contained eight treatments in four replicates. The obtained data showed that concentration and uptake of macro and micronutrients were increased with both soil and foliar fertilization. Superior treatments realized best concentrations; uptake, Mg/P, K/Mg and Ca/Mg ratios in the shoot tissues were 120 kg ha-1 MgSO4 as soil addition or 5 g L-1 in the spray solution as foliar fertilization. However, the treatments achieved highest dry biomass accumulation and plant height were 60 kg ha-1 MgSO4 or 5.0 g L-1 in the spray solution. Accordingly, wheat plants grown on the Egyptian and similar soils are recommended to be supplied with magnesium fertilizers in order to achieve good growth and higher production.
INTRODUCTION
Magnesium is related to the group "secondary elements" and involved in many metabolic processes in the plants. Magnesium ionic form (Mg++) adhered to the colloidal particles in the soil is available to be taken up by the plant roots. Chlorotic or necrotic spots spread over the leaves indicate its deficiency. Magnesium deficiency was reported in some Egyptian soils (Attala et al., 1997; El-Safty and Rabii, 1998; Abou Aziz et al., 2000; Dawood et al., 2001). According to El-Fouly et al. (2010) available Mg decreases in the period 1998-2006 reached about 80% from the available Mg in 1998.
Wheat (Triticum aestivum L.) is the first food source in Egypt. According to FAO documents, production of wheat grains in Egypt reached 8.4 million tons in the year 2011. However, this production still far from covering the population needs, where Egypt imports of wheat grains in the same year reached about 15.7 million tons (FAO, 2011). This reflects the huge gap between consumption and production, which mandate supply of adequate and balanced nutrition for wheat crop plants in order to vertically increase crop production.
This study aimed at studying the response of wheat plants grown on sandy loam soil to magnesium sulphate as soil amendment and foliar fertilization.
