Peat-Based Organo-Mineral Fertilizer Improves Nitrogen Use Efficiency, Soil Quality, and Yield of Baby Corn (Zea mays L.)

The application of organo-mineral fertilizers (OMFs) is gaining popularity day by day because of their potential effect on crop productivity and soil fertility enhancement. Therefore, this research was conducted to observe the effect of a peat soil–urea (PSU) fertilizer on baby corn yield, quality, nitrogen (N) use efficiency, and soil quality compared with commercial urea. A completely randomized design (CRD) with four replicates was used to set up the experiment. In this trial, N was applied from three sources, viz., urea, PSU-L (low N = 15%), and PSU-H (high N = 25%) at a rate of 50, 75, and 100% of the recommended N application dose. The growth, yield, quality, and N use efficiency of baby corn were significantly impacted by the application of PSU fertilizer to the soil. Substantially higher leaf chlorophyll, cob vitamin C, and protein content were found in PSU-treated plants compared with commercial urea. The application of PSU produced about 21% higher cob and a 14% fodder yield over commercial urea. On average, the N uptake by baby corn was 22% higher in PSU-treated plants than urea-treated plants, resulting in 24 and 33% higher N use efficiency and fertilizer N use efficiency, respectively, in PSU than commercial urea. Therefore, the N application rate could be reduced by around 30% using PSU as an alternate N source compared with using commercial urea. In addition, the application of PSU to soil substantially increased the soil organic carbon (SOC) content, whereas SOC decreased in urea-treated soil.

Effect of plant population density of black maize on plant growth, baby-corn yield, and biomass

The plant population density implemented in the number of plants per hole, namely 1, 2, 3, and 4 plants per hole, was tested using Completely Randomized Block Design with 3 replications. Each experimental unit measuring 3m × 3.5m with a plant spacing of 75cm × 25cm. Maintenance of experimental plants following the standard recommendations for corn cultivation. Cow manure 15 tons ha−1 was sown before planting, while NPK fertilizer of 300 kg ha was given 2 times on 2 and 4 weeks after planting, by making a whole, put fertilizer in, then covered with soil again. Detasseling was done before the tassels bloom. Baby corn was harvested up to maximum of 6 days after the ears appear. Biomass was harvested by cutting the plant stand after all baby-corn had been harvested. The observed variables were plant height (cm), number of leaves (strands), stem diameter (mm), days to tasseling (days after planting), fresh and dry weight of plant (g), weight and diameter of ears, baby corn yield ha−1, and biomass yield ha−1. Data collected were analized by analysis of variance and DMRT at α= 5%. The results showed that the population density of black maize had an effect on stem diameter, plant fresh weight, baby-corn yield, and biomass yield per hectare. The largest stem diameter at a population density of 1 plant/hole. The yield of baby-corn per hectare was highest at a density of 3 or 4 plants per hole, and the highest biomass yield per hectare was at a density of 4 plants per hole. The weight, length, and diameter of baby-corn did not differ at various population densities.
