F2 (75% mineral N.P.K. 25% Nano N.P.K. F3 (50% mineral N.P.K. 50% Nano N.P.K. F4 (25% mineral N.P.K. 75% Nano N.P.K. F5 (recommended Nano N.P.K. that put in the main Plots. Fertilizers were added in two and three stages for plant growth. The split plot system was used in the design of the complete randomized sectors with three replications. The results indicate the superiority of cultivar V3 significantly in the characteristics of the number of grains per ears and total grains yield. In contrast, the cultivar V2 recorded the lowest mean of the traits in succession, as evidenced by the results. The level F1 was significant in the characteristics of the number of grains per ears and weight of 500 grains. Whereas, the F3 level exceeded the total grain yield, while the F5 level gave the lowest mean for all traits. We did not notice the presence of significant differences for the factors included in the experiment and their interactions according to the number of stems in the plant.

title: Effect of combination of NPK and nano silica on the levels of b carotene and nutritional value of corn (Zea mays L.
abstract: Maize plant growth can be improved by the addition of a combination of fertilizer such as nano silica and NPK. Nano silica is a fertilizer that contains micro nutrients Si which is needed by monocotyl plants to support its growth while NPK fertilizer contains macronutrient such as N, P, and K. NPK fertilizer combination with nano silica aimed at reducing the use of chemical fertilizers but still can improve corn production This study was conducted to determine the effect of optimal combination of nano silica fertilizer and NPK fertilizers in improving the levels of b carotene and nutritional value of corn (Zea mays L. Fertilization of nano silica is done by spraying the leaves and stalks of corn plants. NPK fertilizer is given on the edge of the corn crop at a distance of 5 cm from maize, while the dose is given by calculating fertilizer requirement per plant by a dose of fertilizer per plant. There are 5 treatments in this study: P0 (without any fertilizer) P1 (25% n anosilica+ 75% NPK) P2 (50% nano silica 50% NPK) P3 (75% nano silica 25% NPK) P4 (100% nano silica 0% NPK) P5 (0% nano silica+ 100% NPK) Each treatment was repeated 3 times. The parameters of this study consisted of the content of b Carotene and measured using spectrometry and nutritional value i.e. total carbohydrates, crude protein, crude fiber, fat content, ash content, and moisture content were determined by proximate analyzed. The data were analyzed using Analysis of Variance (ANOVA) if there is a significant difference result can be followed by Duncan Multiple Range Test (DMRT) at the 95% significance level. The results show that the combination of nano silica fertilizer and NPK fertilizer have effects on levels of b carotene and nutritional value of corn (Zea mays L. The combined use of NPK fertilizer and nano silica increase beta carotene and nutritional value compared to corn plants that were not given fertilizer. The most optimal combination of fertilization to maximize the growth of maize is 75% of nano silica fertilizer and 25% NPK fertilizer.

abstract: Field experiments were conducted to compare nano NPK fertilizers with ordinary mineral NPK fertilizers on maize (Zea mays L. Triple hybrid Giza 320) grown on a saline sodic sandy loam soil. Two experiments were conducted on 2018 and 2019 seasons at Romanh Village, North Sinai Egypt. The design was a randomized complete block, factorial (split plot) Factor1: Source (i.e. mineral 'S1' and nano 'S2' Factor2 Dose "rate" (i.e. kgha NPK of 0/0/0, 120/180/60; 180/36/120 and 240/72/180 for D0, D1, D2 and D3 respectively. The fertilized treatments using the nano forms were much superior then those of the regular mineral ones. Superiority was up to the followings for each 8 and 12% for grain and straw yields respectively. For the other traits, superiorities for uptakes were up to 29% (straw N) 3% (grains N) 41% (straw P) 7 (grain P) 27% (straw K) and 34% (grain K. Fertilization enhanced plants to sustain salinity stress conditions. The mineral fertilization caused plants to accumulate more proline "g kg fresh matter" average of 44.3 for the mineral and 27.4 for the nano.

title: Application of Inorganic Fertilizer With NanoChisil and Nanosilica on Black Corn Plant Growth (Zea Mays L.
abstract: Corn is one of the most important sources of carbohydrate and protein in Indonesia, while black corn has not been widely known. One way to increase the growth of black corn plants is to optimize the use of fertilizer, i.e. by a combination of NPK fertilizer with NanoChisil or Nanosilica fertilizer. NanoChisil is a fertilizer with chitosan and silica, while nanosil fertilizer is a fertilizer with silica content. Both of these fertilizers are nano sized. NPK is a fertilizer with nutrient contents of Nitrogen, Phospor and Potassium. This study aims to determine the combination effect of NPK fertilizer with NanoChisil or Nanosilica on the growth of black corn plants. This research used Completely Randomized Design (CRD) The treatments used were P0 control (without fertilization) P1 (25% NanoChisil 75% NPK combination) P2 (25% Nanosilica 75% NPK combination) P3 (100% NanoChisil) P4 (100% Nanosilica) The study consisted of 5 treatments with 5 repititions. The research parameters consist of plant height, number of leaves, wet weight, dry weight, and the stomata amount. The data analysis used is Analysis of Variance (ANOVA) if the difference is evident, the analysis is continued by Duncan Multiple Range Test (DMRT) at 95% significant level. The results showed the use of NPK fertilizer combination with NanoChisil and NPK fertilizer with Nanosilica have an effect to increase plant height, number of leaves, wet weight, and dry weight. The allocation of 25% NanoChisil 75% NPK is most optimal in increasing plant height, number of leaves, wet weight, and dry weight.

abstract: Only limited work has been focused on the simultaneous evaluation of foliar application of nano nutrients, salicylic and ascorbic acid on agronomic traits of forage corn. Therefore, to evaluate these treatments, the split plot experiment based on RCBD with three replications was used in this experiment. Foliar spraying of nano fertilizers Fe, Zn, K, NPK and control (without fertilizers) were arranged in main plots. The subplots consisted of the foliar spraying of corn with growth regulators including ascorbic acid (2% and salicylic acid (2% and control. Results showed that application of nano iron chelate increased leaf chlorophyll by 29% 20% 20% and 16% compared with control, NPK, potassium and zinc respectively. The highest leaf chlorophyll was observed in the salicylic acid (47.85) and lowest belonged to control treatment (44.38) The highest and lowest plant height belonged to nano iron chelate (2.90 m) and control (2.35) treatments, respectively. The highest value of stem and total dry weight were achieved when NPK fertilizers were applied and the highest leaf dry weight was obtained in nano iron chelate treatments. Salicylic acid caused a 3% increase in leaf dry weight compared to the control. Nano zinc spraying increased plant height by 23.6 m (5% compared to the control. Among the growth regulators, the highest crude protein was observed in salicylic acid treatments.
