“…The other treatment combinations at 80, 110, and 140 DAT showed differences, but the height of the seedlings was still below the value found at the highest dose, as indicated in Figure 1. NPK fertilizer application was discovered to influence growth of seedlings [14]. The high growth rate of oil palm plants observed in this study (Figure 1) was consistent with other results reported by [15] that the addition of NPK fertilizer (16:16:16) increased plant height.…”

This study aimed to investigate the effects of NPK fertilizer and coconut husk ash as an ameliorant on growth and photosynthetic levels of oil palm seedlings in peat soil growth media. A Completely Randomized Design (CRD) was used with two factors, NPK 12:12:17:2+TE including control, 30 g, 60 g, and 90 g per plant. Coconut husk ash includes control, 40 g, 80 g, and 120 g per plant. The data were statistically analyzed using ANOVA, and any observed significant difference led to Duncan's test at p<0.05. The combination of 90 g of fertilizer dose and 80 g of coconut husk ash produced the tallest plant height of 104.53 cm. The highest increase in stem girth was 6.01 cm. The photosynthetic rate was 39.11 μmol CO2 m-2 s-1, and the highest stomatal conductance was 0.21 H2O m-2 s-1. The highest internal CO2 and Water Use Efficiency was 177 μmol CO2 mol-1 and 16.15, respectively, while the best transpiration rate was 2.94 mM H2O m-2s-1. Additionally, the photosynthetic rate positively correlated with seedling height and stem diameter, with a R2 0.25 and 0.44 coefficient, respectively. Stomatal conductance was positively correlated with stem diameter, namely R2 0.04. Meanwhile, transpiration rate was negatively correlated with seedling height (R2 17%) and seedling stem diameter (R2 6.9%). Intracellular CO2 was negatively correlated with plant height but positively correlated with stem diameter. The results of this study are expected to be used in increased growth and photosynthesis.

“…Additionally, the NPK nutrients are essential for respiration, osmotic control, transpiration, photosynthesis and other processes [19]. Moreover, Applying basil plant with NPK fertilizer produced the highest active ingredients contents [20]. As was previously noted, both NPK fertilization and bio-fertilization treatments (each separately) boosted guaran output.…”

At the Experimental Farm (Ghazala Farm) of the Agric. Fac., Zagazig University, Egypt, two field experiments were conducted through the two successive summer seasons in 2019 and 2020. This was an effort to improve the guar plant’s yield and productivity. The experiment was set up as a split-plot design with NPK fertilization as the main plot and bio-fertilization as the sub-plot. The Bradyrhizobium spp. inoculation rates were (0.0, 200 and 400 g/feddan), while the NPK fertilization levels were (0.0, 75, 100, and 125% of recommended level). Ammonium sulphate (20.5% N) at 200 kg/feddan, calcium super phosphate (15.5% P2O5) at 200 kg/feddan, and potassium sulphate (48% K2O) at 100 kg/feddan were the NPK fertilization recommended rates (RR). The obtained results showed that, in comparison to control and the other levels under study, guar plants fertilized with 125% RR significantly increased yield components as well as total carbohydrates content, and NPK percentages in seeds and guaran production. Additionally, compared to the control and lowest inoculation rates of Bradyrhizobium, the maximum inoculation rate (400 g/feddan) considerably recorded the highest values of all the aforementioned parameters. The majority of the study’s findings demonstrated that fertilized guar plants with 125% RR of NPK fertilization, together with 400 g/feddan of Bradyrhizobium inoculation rate, might aid to improve guar plant (Cyamopsis tetragonoloba Taub.) yield, chemical constituents and guaran production.

The present study demonstrates the application of biostimulants during the cultivation of wheat and chickpeas in intercropping farming. This study examined the effect of seaweed on the increasing amount of nitrogen, yield, and nutrient quality of wheat and chickpeas. In north India, rabi crops were grown for three seasons from 2019 to 2021 in the intercropping farming system. The main crop (wheat) was sown with chickpea (legumes) to enhance the yield of two crops in one season as chickpea also helps in nitrogen fixation in soil. There was a total of 36 rows each of 6 m, of which nine rows each were for wheat and chickpea and the other nine were for one row of wheat and another of chickpea. Results of the study, exhibit the significant effect of the amount of nitrogen which was a maximum of 4.33 mg/kg in intercropping treated with seaweed as compared to intercropping with control 4.23 mg/kg. AE (Agronomic Efficiency) in the intercropping with seaweed treatment was 3.27 kg/kg as compared to 3.23 kg/kg in the control. The yield and harvest index of seaweed with intercropping was higher than intercropping in control with chemical fertilizers like urea. Hence, biostimulants along with intercropping were found to be effective in increasing the yield and nutritional value of crops.
