The Effects of Fe, Mn and Zn Foliar Application on Yield, Ash and Protein Percentage of Forage Sorghum in Climatic Condition of Esfahan

Abstract

Improving forage yield and quality remains a major concern of the producer. Among the various ways of supplying nutrient to the crops, the efficient utilization of nutrients by the plants is made through foliar application. Foliar application had significant effect on plant height, the number of leaf, the number of tiller, LAI, fresh forage yield, dry leaf yield, dry stem yield, total dry yield, dry leaf weight/dry stem weight ration and ash percentage. Application methods of micronutrients are very important to attain the best absorption. The results of this study demonstrated that, Fe, Zn and Mn had positive effect on yield and quality of forage sorghum. The highest plant height, LAI, Fresh forage yield, dry leaf and stem yield, total dry yield and dry leaf weight/dry stem weight was obtained in Zn+Fe+Mn application. The highest number of tiller was related to combination of Zn and Mn. The maximum ash percentage and appropriate protein percentage also was achieved in application of Zn+Fe+Mn. So, on the basis of the results, it seems that application Zn+Fe+Mn was suitable to gain high forage yield and gain to high quality.

Role of foliar feeding of micronutrients in yield maximization of cotton in Punjab

“…Six micronutrients (boron, manganese, iron, copper, zinc, and molybdenum) play distinct and vital roles in plant physiology and biochemical processes (Putra et al 2012;Rab and Haq 2012). The scarcity of any nutrient in the soil can be a barrier to growth, even when all other nutrients are in excess in the soil (Soleymani and Shahrajabian 2012).…”

“…The field scale deficiency of these nutrients in Pakistan has hampered seed-cotton productivity during the last decade (Ali 2012;Soleymani and Shahrajabian 2012) and it is predicted to get worse in the future.…”

“…Usually, it is recommended for horticultural crops, e.g. tomato (Rab and Haq 2012), but it has also been found as a more effective technique for correcting micronutrient deficiency in cereal crops like wheat (Yassen et al 2010;Bameri et al 2012) and sorghum (Soleymani and Shahrajabian 2012). Moreover, this technique generated additional benefits, in terms of cash, when applied in the right dose at the right time admixed with an appropriate surfactant (Oosterhuits et al 2010).…”

Influence of Sowing Times, Densities, and Soils to Biomass and Ethanol Yield of Sweet Sorghum

“…The amounts of N, P, and K in soils are critical to determine fertilizer doses incorporated to soils to increase the yields of sorghum as well as other crops [30,31]. Small amount of nutrients, particularly Zn, Fe, and Mn applied by foliar spraying significantly promote the yield of crops [32]. The content of Al in soil may cause Al 3+ toxicity which is the primary factor limiting crop growth [33].…”

Demonstration and evaluation of the effect of various doses of fertilizer on the growth and yield of seed cotton in ecological zone of Bahawalnagar

“…The use of N and P fertilizers increased many fold since their introduction in the late fifties (Ahmad, 2000). The scarcity of any nutrient in the soil can be a barrier for the growth of crops even when all other nutrients are in excess in the soil (Soleymani and Shahrajabian 2012 (125 kg ha -1 ) but use of K fertilizer is negligible (Mithaiwala et al, 1981). Colakoglu, (1980) recommended optimum dose of 80-120 kg ha -1 N, 60-90 kg ha -1 P and 100-200 kg ha -1 K for optimum seed cotton yield.…”
