Effect of Intercropping of some Legume Forage Crops with Maize Under Levels of Mineral Npk and Nano Npk Fertilizer

Abstract

A field experiment was carried out at Mallawi Agricultural Research Station, Minia Governorate, ARC, during two successive summer seasons of 2017 and 2018 to study the effect of intercropping three fodder crops on productivity, quality and profitability of maize cv. Giza 168 and using different rates of NKP nano + mineral fertilizer. A complete Randomized Block Design in a split plot arrangement with four replicates was used in both seasons. Main plots were devoted for the following three fodder crops guar, cowpea and cilitora 50% of the recommended. The following rates of fertilizer , 100 % NPK mineral fertilizer, 100% NPK nano fertilizer,75% nano+25% mineral fertilizer, 50% nano + 50% mineral fertilizer and 25 % nano+ 75% mineral fertilizer added for maize from recommended does were allocated in the subplots. The highest values of these characters were obtained with 75% nano fertilization NPK + 25% mineral fertilization NPK fed -1 . Maize grain yield could be noted from the combined analysis that the yield of grain (ardab/fed) was representing 3. 07, 9.71.18.11.8.95 and 8.81% of pure stand of maize, respectively. The percentage of protein, phosphorus and potassium in maize grains increased in percentage compared to the individual in both seasons and combined. Intercropping cilitiora with maize and using 100 % mineral fertilizers recorded the lowest values for (LER& ATER). Net return of intercropping cowpea with maize and using rate 75% nano and 25 % mineral fertilizer 8589.4L.E. fed-1 an average of the two successive seasons.

Comparative Study on the Efficacy of Various Nano Fertilizer Levels, NPK Foliar, and Soil Applications in Enhancing the Growth and Yield of Kharif Maize (Zea mays L.)

“…Furthermore, the combination of foliar application with RDF resulted in a significant increase in grain and straw yield, as well as improvements in quality parameters. Similar findings have been reported in studies conducted by Yomso and Menon (2021), Mundhe et al (2022), Ahmed et al (2019), Sannathimmappa et al (2023), Iqbal (2019), and Midde et al (2022).…”

Effect of Spraying Nano Fertilizer NPK and Nano Fertilizer Microelements on the Growth Characteristics of Maize Plants (Zea May L.)

“…The cultivation area was determined, and soil samples were taken from different places before planting at a depth of (0-30 cm). They were mixed and blended well, then ground and sifted through a sieve with a diameter of 2 mm to analyze some of their chemical and physical characteristics, which are shown in Table (1). A factorial experiment was carried out according to the randomized complete block design (R.C.B.D).…”

“…Soil degradation due to a lack of organic matter and lack of nutrients and following the wrong agricultural methods such as the use of fertilizers and non-rational pesticides and irrigation by traditional methods, which cause the depletion of nutrients from the soil and not replace them and increase the content of lime and the high rate of pH leads to a reduction in production and a lack of availability of nutrients. [1], which called for the need to compensate for the deficiency through the fertilization process, as the researchers confirmed that foliar feeding is optimal to compensate for the deficiency that occurred, although it is often supplementary feeding, it is characterized by its ability to quickly treat nutrient deficiency, especially when there are problems in supplying nutrients through the roots. Plant and can contribute to compensation for a certain amount of land addition when properly managed [2].…”
