“…Wheat (Triticum aestivum L.) is the second most important food crop in Egypt which remains the world's largest wheat importer (Elzemrany et al, 2021). Wheat grains contain protein of 6-21%, minerals of 1.8%, the starch of 60-68%, cellulose of 2.0-2.5% and fats of 1.5-2.0% (El-Ghamry et al, 2021 andGhazi et al, 2022).…”

Soil salinity is one of the biggest widespread abiotic stresses severely restricting crop production. Under stress, several extracts have been used as effective natural bio-stimulants. However, the combined influences of soil organic amendments and natural bio-stimulants on the production and defenses of plants grown under the dual stress of salinity and alkalinity are still only rudimentarily known. So, a field experiment was executed during the winter season of 2020/2021to assess the effectiveness of various organic amendments and the foliar application of various stimulants in reducing the detrimental effects of soil salinity on wheat plants grown under saline-alkali stress (electric conductivity = 13.2 dSm -1 and exchangeable sodium percentage = 15.1%).Twenty treatments were executed in a split plot design. The organic amendments[without soil addition (control), vermicompost, compost and chicken manure] were devoted in the main plots, while thebio-stimulants (without foliar application (control), moringa leave extract, licorice root extract, ginger extract, and humate potassium) were allocated in the sub plots. The findings illustrated that the highest plant's self-production of proline and enzymatic antioxidants i.e. catalase enzyme, peroxidase and superoxide dismutase were realized whenwheat plants were treated with vermicompost and sprayed with moringa extract, while the lowest values of proline and enzymatic antioxidants were recorded with untreated plants (without soil and foliar application). Regarding the yield and its components, the highest value of yield was realized with wheat plants treated with vermicompost and moringa extract simultaneously.

“…Wheat crop is the main winter cereal crop in all countries of the world. In Arab countries, there is an urgent need for the maximization of wheat crop production because the local production isn't sufficient to equal the annual requirements (El-Ghamry et al, 2021;Elzemrany et al, 2021 andYaylac ı , 2021). The soil addition of some conditioners to sandy soil increases the wheat productivity.…”

Nanotechnology has the potential to increase the efficiency and quality of agricultural production. So, this research work was carried out to assess the effect of some soil conditioners at different rates and foliar application of antioxidant on the performance of wheat plants grown on sandy soil. The treatments were T 1 : Control (without soil addition);T 2 : 0.50%Normal compost (bulky);T 3 : 0.25% Nano compost;T 4 : 0.50% Nano compost;T 5 : 0.50% Normal agricultural gypsum (bulky);T 6 : 0.25% Nano agricultural gypsum;T 7 : 0.50% Nano agricultural gypsum; T 8 : 0.50% Normal sugar lime mud (bulky);T 9 : 0.25% Nano sugar lime mud;T 10 : 0.50% Nano sugar lime mud; F 1 : without proline and F 2 : with proline.Wheat plants treated with compostpossessed the highest values of all growth criteria (e.g.,fresh and dry weights, plant height and leaf area), photosynthetic pigments (after 70 days from sowing), yield, its component, and grains quality (at harvest stage) under sandy soil conditions followed by that treated with agricultural gypsum than the plants treated with sugar lime mud, while the untreated wheat plants with any soil conditioner (control treatment) possessed the lowest values of all aforementioned traits. Nano form was superior compared to the normal form with all studied soil amendments. Also, all aforementioned traits increased as the rate of Nano form increased with all studied soil amendments.Regarding the foliar application, the proline treatment was superior compared to the control treatment (without foliar application). The control treatment (without soil and foliar applications) led to raising the enzymatic antioxidants content in the straw of wheat plant after 70 days from sowing, where the cultivation without any both soil conditioners and proline caused an increase in wheat self-production from these antioxidants to scavenge the ROS (or as named free radicals) resulting due to the poverty of sandy soil, thus increase of tolerance. Generally, it can be concluded that all the studied soil conditioners (i.e., gypsum, compost, and sugar lime mud) in either normal form or Nano form have a beneficial effect on improving the performance and productivity of wheat plants grown under sandy soil conditions. Also, the findings of the current work confirmed proline is one of the plant's protective ways from the poverty of sandy soil fertility, where it works as an antioxidant and leads to an increase in wheat plant tolerance to the poverty of sandy soil fertility.

“…It is worthy to mention that up to 98 % of soil-K was found unavailable for plant uptake (Meena et al, 2016). Accordingly, farmers depend on commercial inorganic fertilizers to satisfy plant needs for K (Meena et al, 2016Marzouk et al, 2020and Elzemrany and Faiyad, 2021; however the efficiency of these fertilizers may increase when applied in combination with organic additives (Qaswar et al, 2020, Emam et al, 2020andAbou Hussienet al, 2021 such as manure and compost (Sánchez et al, 2015). Moreover, organic additives may effectively substitute inorganic K-fertilizers (Jiang et al, 2019) to sustain soil and crop productivity (Meena et al, 2016).…”

Integrated management of K -additives to improve the productivity of zucchini plants grown on a poor fertile sandy soil

et al. 2021

Three eco-friendly approaches were investigated for their effects onimproving K-uptake by zucchini plants; hence, increasing shoot growth and fruit productivity. These approaches were: (1) amending soil with biochar (0 and 5g kg -1 ), (2) spraying plants with Amphora extract (0 and 1g L -1 ) and (3) substituting inorganic-K fertilizers partially with organic ones. In this concern, five levels of compost (0, 1.5, 3, 4.5 and 6 g kg -1 ) were applied to a poor fertile sandy soil (98.5% sand) in complementation with inorganic NPK-fertilizers to bring their concentrations, even in the control treatment, to the recommended levels. This investigation was conducted under the greenhouse conditions during the summer season of 2020. Results obtained herein reveal that application of either of biochar or Amphora extract exhibited positive effects on soil available-K (20 and 6.5% respectively), Kconcentrations in fruits and total K-uptake by the aboveground plant parts. Furthermore, these two amendments raised considerably the dry weights of both zucchini shoots and fruits. On the other hand, compost could partially substituteinorganic-K fertilizers when it was applied at a rate not exceeding 3gkg -1 ,recording significant improvements in all the investigated parameters. Nevertheless application of high compost doses reduced significantly fruit yield. Generally, there existed a highly significant linear relation between the total K-uptake by plants and fruit dry weights. Accordingly, treatments that improved considerably K-uptake by plants(the combination between foliar application of amphora extract + 5 g kg -1 biochar + 0-3 gkg -1 compost)recorded the highest improvements in productivity of zucchini plants.
