“…There were no unmarketable fruit in 2012 in the treatments where kaolin was applied. Yield increases of fruits and vegetables by the application of kaolin in previous studies were attributed to lower disease incidence (Creamer et al 2005, less water and heat stress (Spiers et al 2004, Creamer et al 2005, higher levels of chlorophyll in the plants (Creamer et al 2005), and decreased damage from sunburn (Cantore et al 2009). …”

“…In tomatoes, kaolin reduced fruit temperature and sunburn damage, and increased lycopene content and red coloration of the fruit (Cantore et al 2009). On chile peppers, kaolin reduced water stress, increased levels of chlorophyll, and increased light reßectance of leaves (Creamer et al 2005). Different species of thrips or their damage were reduced on crops by applying kaolin.…”

“…Some studies indicated that kaolin applications increased crop yield (Spiers et al 2004, Cantore et al 2009) while other studies indicated decreased yield or no difference (Wilson et al 2004;Creamer et al 2005;Khan et al 2008a,b;Larentzaki et al 2008).

A push-pull strategy for managing the anthophilous Frankliniella bispinosa (Morgan) in pepper and increasing conservation biological control was evaluated. Push components of ultraviolet (UV)-reflective mulch and foliar applications of kaolin and the pull component of sunflower companion plants were evaluated in replicated field experiments in 2011 and 2012. Adult F. bispinosa rapidly colonized and reproduced in the peppers and sunflowers during early flowering, but populations declined later, as numbers of the predatory Orius insidiosus (Say) and Orius pumilio (Champion) increased in both hosts. Numbers of F. bispinosa were reduced by kaolin during early pepper flowering. Thrips numbers were increased on some of the later sample dates, apparently due to reduced predation that resulted from negative effects of kaolin and UV-reflective mulch on Orius populations. Numbers of thrips increased in peppers with companion plants during the first week of flowering each year, followed by declines in thrips numbers during the next 2 wk in 2011. There was little effect each year of the companion plants on the numbers of Orius in the pepper flowers. There was one date in 2011 and no dates in 2012 in which UV-reflective mulch or kaolin acted in concert with the presence of the companion plants to reduce thrips numbers in the main crop of pepper. Yield effects were not attributed to thrips damage. We conclude that sunflower companion plants did not act additively or synergistically with kaolin or UV-reflective mulch to reduce thrips and increase Orius populations in pepper.

“…Another technique that claim to reduce water use by plant is the reflectance type of antitranspirants as magnesium carbonate and kaolin, which are natural white materials form a coating film on the leaves, it increase the leaf reflectance by reflecting the radiation and increase the vapour pressure gradient and thus reduce transpiration (Glenn et al, 2002 andCreamer et al, 2005). In this respect, Abd El-Aal et al (2008) mentioned that foliar application of MgCO3 at rate 2% gained more growth vigor and more fruits yield as well as better physical and chemical properties of eggplant compared with no-treated plants.…”

Two field experiments were conducted at a private farm near EL-Mansoura city, El-Dakahlia Governorate, Egypt, during the two successive seasons of 2011 and 2012 to study the effect of three water irrigation levels, the first was 2600 m 3 fed -1 as the control treatment (the traditional irrigation amount used by the farmers in the area), the 2 nd and the 3 rd treatments were 1800 and 1000 m 3 fed -1 , respectively, as deficit irrigation treatments as well as four foliar applications, i.e., control, magnesium carbonate, kaolin and potassium silicate on growth, chemical composition, yield, water use efficiency and fruit quality of sweet pepper plants (Gedeon F1 Hybrid) cultivated under drip irrigation system in clay-loam soil at northern of Nile Delta lands. The main results could be summarized as follows:-Applying the high irrigation water level (2600 m 3 fed -1 ) or the deficit level (1800 m 3 fed -1 ) combined with foliar application of kaolin or potassium silicate showed the highest significant values of all studied vegetative growth aspects, i.e., stem diameter, relative growth rate, net assimilation rate and leaf relative water content. -Applying 2600 m 3 fed -1 combined with foliar application of potassium silicate and 2600 or 1800 m 3 fed -1 combined with foliar application of kaolin or potassium silicate significantly increased NPK uptake by sweet pepper plants foliage. -Applying 1000 m 3 fed -1 combined with foliar application of kaolin or potassium silicate significantly increased total chlorophyll contents in sweet pepper leaves. -All studied yield characteristics, i.e., number of fruits per plant, average fruit weight, early yield and total yield per feddan as well as water use efficiency were significantly increased by applying 1800 m 3 fed -1 of irrigation water combined with foliar application of kaolin or potassium silicate. -The highest significant values of vitamin C, total soluble solids, reducing sugars and total sugars contents in sweet pepper fruits were significantly affected by applying the deficit irrigation treatments (1800 or 1000 m 3 fed -1 ) combined with foliar application of kaolin or potassium silicate. -Fruit flesh thickness was significantly increased by applying 2600 m 3 fed -1 combined with kaolin or potassium silicate foliar application. -The highest net return was obtained by applying 1800 m 3 fed -1 combined with foliar application of kaolin; such treatment returns the highest benefit-cost ratio (2.51).In conclusion, this investigation demonstrate that irrigation sweet pepper plants with 1800 m 3 fed -1 combined with kaolin foliar application (4%, 4 times during the season) could be recommended to improve the vegetative growth characteristics, chemical composition, total yield, water use efficiency and fruit quality, saving about 30% of the total used irrigation water quantity in sweet pepper production. Such treatment can be recommended under drip irrigation system in clay-loam soil at northern of Nil Delta lands, giving the highest net return and benefit-cost ratio to the fa...
