Effect of Preceding Crops and Foliar Micronutrients Applications on Yield and Yield Components of Bread Wheat Under Sandy Soil Conditions

Abstract

ASL), to evaluate the effect of fallow (control), clover and fodder maize as a preceding crops and foliar application of some micronutrients on yield and yield components of wheat cv. Gemmiza 11. The experimental design was split plot with three replications. Main plots were allocated by preceding crops and sub plots were occupied by three micronutrients salts FeSO 4 , ZnSO 4 and MnSO 4, in seven combinations of micronutrients foliar application T1: (Fe +Zn + Mn), T2: (Fe +Zn), T3: (Fe + Mn), T4: Fe, T5: (Zn + Mn), T6: Zn and T7: Mn. Micronutrients were sprayed three times at 30, 60 and 90 days after sowing. Results showed that wheat significantly affected by the preceding summer crops. Clover as a preceding crop left good residual effect on wheat plant which gave the highest values for all studied characters e.g. plant height, number of spikes/m 2 , No. of spikelets/spike, No. of grains/spike, 1000 grain weight and grain yield as well as straw and grain contents from Fe, Mn and Zn in the two seasons. With respect to micronutrients, the results showed that the differences between these treatments had significant effect on each of plant height, number of spikes/m 2 , No. of spikelets/spike, No. of grains/spike, 1000 grain weight and grain yield. The foliar application of mixture nutrients (Fe + Mn + Zn) produced the highest values of yield and its components during both seasons. Moreover, the foliar spray of Fe, Mn and Zn (alone or together and all three nutrients) has significant effect on wheat straw and grain-Fe, Mn and Zn concentration during the two seasons. Also, the results indicated that the interaction between preceding crops and micronutrients treatments had insignificant effect on all studied characters, except 1000 grain weight in the first season and number of spikelets/spike in the second one. In conclusion growing wheat following to clover and foliar application by mixture of Fe+Mn+Zn produced the maximum net income valued 2186 and 2098 LE.fad -1 during two seasons, respectively, compared to the other treatments.

Appropriate crop sequence and N fertilization levels of wheat to improve its productivity in Egypt

“…The sequence of corn-clover-wheat produced higher grain and straw yield when compared to the sequence of corn-fallow-wheat (Gad et al, 2018). Clover as a preceding crop left a good residual effect on the wheat plant which gave the highest yield and its components compared to fodder maize and follow (Abd Allah et al, 2020).…”

“…Pagnani et al (2019) found that wheat-faba bean sequence produce the highest grain yields, due to an increased number of spikes/ m 2 , while the lowest grain yield was recorded under wheat-wheat. The superiority of grain and straw yields of wheat grown after clover may be attributed to the high values of most of yield components such as number of spikes/m2, number of grains/spike and 1000-grain weight (Abd Allah et al, 2020). Variation of wheat yield after different legume sequence could be attributed to legumes differing in the amount of biological N2 fixation.…”

Impact of Preceding Crop, Sowing Methods and Nano-Fertilizer (Amino mineral) on Bread Wheat Production and Quality in Toshka Region, Egypt

“…Hamdany et al (2016) indicated that the highest values of cereal units, economic evaluation, net return and improved physical and chemical properties of soil for the next planting resulted from the crop sequence corn followed by fahal berseem one cut followed by wheat compared the other treatments in both seasons. Growing wheat after soybean and clover (as legume crops) increased plant height, number of spikes m -2 , number of spikelets spike -1 , number of grains spike -1 , spike length, grain weight spike -1 , 1000-grain weight, straw yield, and grain yield (Abomarzoka & Hamadny, 2017;Gad et al, 2018;Abd Allah et al, 2020). Likewise, Andrii et al (2021) indicated that after the preceding crop soybean, wheat crop gained the maximum yield (5.77ton ha -1 ).…”
