“…This enhanced chlorophyll production leads to improved photosynthetic efficiency and, consequently, higher growth rates and biomass accumulation. Similar findings have been reported in related research, such as Pandey’s 39 investigation into maize and soybean intercropping systems, where the provision of shade resulted in elevated chlorophyll content.…”

Over the past century, the average surface temperature and recurrent heatwaves have been steadily rising, especially during the summer season, which is affecting the yield potential of most food crops. Hence, diversification in cropping systems with suitable fertilizer management is an urgent need to ensure high yield potential during the summer season. Since intercropping has emerged as an important strategy to increase food production, the present study comprises five intercropping systems in the main plot (sole cowpea, sole baby corn, cowpea + baby corn in 2:1, 3:1, and 4:1 row ratio), three levels of fertilizer viz. 100 (N20 P40), 125 (N25 P50), and 150% (N30 P60) recommended dose of fertilizer (RDF) in the subplot, along with two stress-mitigating chemicals (0.5% CaCl2 and 1% KNO3) in the sub-sub plots. A split-split plot system with four replications was established to carry out the field experiment. The effect of intercropping, fertilizer levels, and stress-mitigating chemicals on crop growth rate (CGR), relative growth rate (RGR), plant temperature, relative water content (RWC) and chlorophyll content of cowpea and baby corn, as well as cowpea equivalent yield (CEY), was investigated during the summer seasons of 2019 and 2020. The experiment was conducted at Agriculture University, Kota (Rajasthan), India. Results showed that CGR, RGR, RWC and chlorophyll content of both crops and CEY were maximum under intercropping of cowpea and baby corn in a 2:1 row ratio compared to other intercropping systems. However, the plant temperature of both crops was significantly lower under this system. CEY, CGR, RGR, and chlorophyll content were considerably greater in the subplots with a fertilizer application of 150% RDF compared to lower levels of fertilizer (100 and 125% RDF). Our findings further show that foliar application of CaCl2 0.5% at the flowering and pod-developing stages of cowpea dramatically boosted CEY, CGR, RGR, RWC, and chlorophyll content of both crops and lowered the plant temperature.

The current study evaluated the impact of intercropping Cowpea and Moong bean on Maize yield and its constituent parts. Nine different treatments were used in the experiment viz., (T1) sole Maize, (T2) sole Cowpea, (T3) sole Moong bean, (T4) Maize + Cowpea (1:1), (T5) Maize + Cowpea (1:2), (T6) Maize + Cowpea (1:3), (T7) Maize + Moong bean (1:1), (T8) Maize + Moong bean (1:2) and, (T9) Maize + Moong bean (2:1) in a randomized block design with three replications in Kharif season. The findings showed that intercropped plants had greater potential and produced higher values for the majority of the studied criteria, including plant height, chlorophyll meter reading (SPAD) number of cobs plant-1, number of rows cob-1, number of grains row-1, 100-grain weight, and straw and grain yields Intercrop’s seed yields were less in intercropped treatments than sole Maize. (T5) Maize + Cowpea (1:2) was best treatment having highest yield (5915.83 kg ha-1), maximum LER (1.8) and MEY (kg ha-1) (11663.36). This clearly demonstrated the advantages of intercropping Maize with legumes. This is because the leguminous crops can provide additional nutrients to the Maize crop through biological nitrogen fixation (BNF). Additionally legumes can improve the declined soil productivity by enhancing the overall soil conditions like chemical, biological, and physical. The increased availability of nitrogen and enhancement in soil physical, chemical and biological properties can improve Maize growth, leading to higher yield. Additionally it boosts soil conservation by providing more ground cover than mono-cropping.

“…Photosynthesis will take place well if maize leaves get optimal nitrogen, because the element N besides forming leaf chlorophyll also adds to plant cell tissue, whether leaf cells, stems, cobs, or seeds. As explained by [23] that nitrogen has the main function as a synthetic material for chlorophyll, protein, and amino acids. Therefore the element Nitrogen is needed in large enough quantities, especially when the growth enters the vegetative phase.…”

The research objective was to determine the role of zeolite in increasing the efficiency of NPK fertilizer on the growth and yield of maize in Inceptisol Southern Solok. This research was conducted in July - November 2022, in Sangir District, Southern Solok Regency, West Sumatra with an elevation of 998 m above sea level, the soil type is Inceptisol, with a soil pH of 5.76, belonging to the slightly acidic. The experiment was arranged in a randomized block design with a factorial arrangement of treatments in 2 treatment factors. The 1st factor was the dose of zeolite from 0, 100 and 200 kg ha-1, the 2nd factor was NPK fertilizer (15-15-15) with a dose of; 100, 200, and 300 kg ha-1, arranged in 3 blocks. The data obtained was analyzed using the F test with a significance level of 5%, and then using the DNMRT follow-up test with a significance level of 5%. The parameters; soil pH, plant height, leaf area index, weight of 100 maize kernels, moisture content of 14%; and yield per hectare. The data obtained were presented in the form of tables and figures, establishing the interaction relationship between the two treatments in the form of graphs. The resulted was giving 100 kg ha-1 NPK was able to provide optimal NPK nutrient uptake, plant height and LAI at 54 DAP. The combination of 100 kg ha-1 zeolite and 200 kg ha-1 NPK provided optimal yields of dry shelled maize reaching 5.44 tonnes ha-1.
