Aiming at the problems of low utilization rate of corn fertilizer, low precision of fertilization ratio, and time-consuming and laborious topdressing in the later stage, an U-shaped fertilization device with uniform fertilizer mechanism was designed. The device was mainly composed of uniform fertilizer mixing mechanism, fertilizer guide plate and fertilization plate. Compound fertilizer was applied on both sides and slow/controlled release fertilizer was applied at the bottom to form an U-shaped distribution of fertilizer around corn seeds. Through theoretical analysis and calculation, the structural parameters of the fertilization device were determined. Through the simulated soil tank test, the quadratic regression orthogonal rotation combination design was carried out on the main factors affecting the spatial stratification effect of fertilizer. The optimal parameters were obtained as follows: the stirring speed of the stirring structure was 300 r/min, the bending angle of the fertilization tube was 165°, and the operating speed of the fertilization device was 3 km/h. The results of bench verification test showed that under the optimized stirring speed and bending angle, the fertilizer particles were stirred evenly, and the average values of fertilizer flowing out of the fertilization tubes on both sides were 299.5 g and 297.4 g, respectively. The average fertilizer amounts of the three fertilizer outlets were 200.4 g, 203.2 g and 197.7 g, respectively, which met the agronomic requirements of 1:1:1 fertilization, and the variation coefficients of fertilizer amounts on both sides of the fertilizer pipe and each layer were less than 0.1% and 0.4%, respectively. The simulation results of the optimized U-shaped fertilization device can achieve the expected U-shaped fertilization effect around corn seeds. The results of field experiment showed that the U-shaped fertilization device could realize the U-shaped proportional application of fertilizer in soil. The distance between the upper end of fertilization on both sides and the distance between the base fertilizer and the surface were 87.3–95.2 mm and 197.8–206.0 mm, respectively. The transverse distance between the fertilizers on both sides was 84.3–99.4 mm, and the error with the designed theoretical fertilization was within 10 mm. Compared with the traditional side fertilization method, the number of corn roots increased by 5–6, the root length increased by 30–40 mm, and the yield increased by 9.9–14.8%.

Surface energy and water balance calculations across crop surfaces improves comprehension of water balance and facilitates water usage that is cost-effective. With this idea, field trails were conducted at Tamil Nadu Agricultural University, Coimbatore during two cropping seasons i.e.,winter (Jan-March) and kharif (June-Sep), 2022 to study crop development, energy balance partitioning and evapotranspiration rate at various growth stage of baby corn under different sowing windows. Energy balance components were studied using Bowen Ratio Energy Balance method (BREB). Crop evapotranspiration was measured and simulated using AquaCrop model. Results clearly indicated that maximum energy balance components such as net radiation (Rn), Latent Heat Flux (LE), Sensible heat flux (H), Ground heat flux (G) were recorded at maturity stage, among crop growing cycle. Early sowing accumulated more amount of energy balance than mid and late sown crops during both seasons. Daily Kc values varied significantly from 0.05 to 1.01 and 0.01 to 0.96 for winter and kharif seasons, respectively. Good correlation was observed between calculated and simulated daily crop evapotranspiration (Etc). The total measured Etc was 486 and 624.4 mm for winter and kharif, respectively whereas AquaCrop simulated ETc of 438.8 mm and 500.4 mm. The digital agricultural technologies like crop simulation models would be useful to increase the accuracy of ET calculation in agricultural water management. This study examines the effective approaches used in estimating ET for baby corn water management which could be made to boost the precision of ET estimation and achieve precise water management.
