Poultry manure-urea fertilizer potentially influences nitrogen use efficiency, nutritional quality, and yield of baby corn (Zea mays L.)

Baby corn (Zea mays L.) is an immature type of corn harvested when the silk length becomes 2–3 inches long and consumed as raw or cooked. However, in recent years the use of organo-mineral fertilizers (OMFs) has been increasing due to their ability to improve crop production and soil health. That's why a pot experiment was carried out to determine the effects of poultry manure-urea (PMU) on baby corn production, nutritional value, nitrogen (N) use efficiency, and soil health compared to commercial urea following a completely randomized design (CRD) with four replications. Here, 3 N-fertilizer sources, viz., urea, PMU-L (low N: 14 %), and PMU-H (High N: 24 %) were applied at 50, 75, and 100 % of the recommended dose of N. Application of PMU fertilizer significantly influenced plant height, yield, nutritional quality and N use efficiency of baby corn. Significantly greater leaf chlorophyll, cob, and fodder protein content were found in PMU-treated plants than in urea. The use of PMU increased cob and fodder production by approximately 11 and 13 %, respectively compared to urea. About 25 % higher N uptake, leading to a 28 % greater N use efficiency by baby corn was found in PMU-treated plants than in urea-treated ones. Besides that, the amount of soil organic carbon (SOC) was slightly increased due to the application of PMU. Results showed that Pb, Cd, and Cr concentrations in PMU treated plants were below the WHO permissible limit.

Nitrogen and detasseling influences growth, yield and economics of male sterile baby corn (Zea mays)

A field experiment was carried-out in the winter season of 2021–22 at the Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, Uttar Pradesh, India, to assess the effect of detasseling times and nitrogen levels on productivity and profitability of winter baby corn (Zea mays L.). The experiment comprised three detasseling times (No detasseling [Control], immediately after tassel emergence, and 7 days after tassel emergence) and four nitrogen levels (50, 100, 150 and 200 kg N/ha). A total 12 treatment combinations were evaluated in a factorial randomized-block design, replicated thrice. The results showed that detasseling immediately after tassel emergence enhanced the dry matter accumulation, yield attributes, and husked and dehusked baby corn yield by 11.4 and 15.2%, respectively and fodder yield (23.84 t/ha), over no detasseling; however, it stood at par with detasseling 7 days after tassel emergence. Further, an application of 200 kg N/ha resulted in the highest dry matter accumulation and yield attributes, finally leading to 36.9, 38.1 and 33.1%, improvement in husked, dehusked baby corn yield and fodder yield, respectively, compared to 50 kg N/ha. Using 150 kg N/ha was at par with 200 kg N/ha both for growth and yield. The net returns and benefit-cost ratio showed the similar trend as of baby corn yields. Overall, this study suggested that detasseling immediately after tassel emergence and application of 200 kg N/ha is advantageous to augment the productivity and profitability of winter baby corn under irrigated ecosystem of eastern Uttar Pradesh.

GGE biplot and AMMI analysis for stability and adaptability of dual-purpose maize hybrids tested across multi-environments for baby corn and fodder yield

Meeting the growing demand for baby corn necessitates the development of dual-purpose hybrids that are both high-yielding and genetically stable. Accordingly, the present study aimed for multi-location testing of twelve newly crossed elite baby corn hybrids along with one check CMVL BABY CORN-2 across four environments during Rabi 2021-22. Analysis of variance underscored the significant impact of genetic (G), environmental (E), and their interaction (GE) on all traits under study. The environment was the most important source of variation for all the traits, followed by G (3.37–10.51%) and GE (1.03–2.77). The first two principal components explained 88.48, 87.52 and 76.03% of the total variation for DS, BCY and GFY, respectively. Environmental evaluation classified locations into three distinct mega-environments viz. ME I encompassed Hyderabad and Hazaribagh, and ME II and III were represented solely by Ludhiana and Varanasi, respectively. Based on the GGE biplot and AMMI analysis, genotypes T9 and T11 exhibited superior performance and stability across multiple locations over the check for both BCY and GFY traits.

Effects of integrated nutrient management and fertilizers on the yield of baby corn in Punjab's climatic context

The combined impacts of climate change and increased chemical fertilizer use are diminishing soil fertility, thereby reducing agricultural productivity and farmland yield potential. This study investigates the effect of integrated nutrient management on baby corn. Results showed that the highest cob length (14.28 cm) and green fodder yield (45.56 t ha-1) were achieved using elevated levels of nitrogen (160 kg ha-1) and phosphorus (120 kg ha-1), supplemented with zinc (6 kg ha-1) and Azotobacter. Soil nutrient availability was assessed, indicating that treatment with 160 kg N + 100 kg P + 6 kg Zn + Azotobacter results in available nitrogen levels of 277.2 kg ha-1 and the highest organic carbon content (0.26%). Available phosphorus content (ranging from 24.1 to 24.3 kg P ha-1) is observed with 120 kg P. Nutritional quality parameters were also influenced by nutrient levels, with the treatment of 160 kg N + 120 kg P + 6 kg Zn + Azotobacter showing the highest total soluble solids (11.2% brix) and protein content (17.9%). The treatment of 140 kg N + 100 kg P + 6 kg Zn exhibits the maximum fiber content (26.5%). In summary, the study underscores the positive impact of biofertilizers and zinc on fodder yield and soil properties. Integrating biofertilizers and micronutrients is recommended for sustaining agriculture and maintaining soil health over the long term.

The impact of Klebsiella quasipneumoniae inoculation with nitrogen fertilization on baby corn yield and cob quality

In response to the escalating costs and diminishing efficiency of nitrogen fertilizers, the agricultural community is actively seeking sustainable alternatives that leverage natural nitrogen sources derived from biological N-fixation processes to enhance crop yield. This study investigates the combined effects of Klebsiella quasipneumoniae inoculation and varying nitrogen fertilizer doses on soil fertility, nutrient availability, and the yield and quality parameters of baby corn (Zea mays. L). The study involved the application of five nitrogen levels (0, 75, 150, 225, and 300 kg N ha-1) in conjunction with Klebsiella quasipneumoniae inoculum on HM-4 variety of baby corn, employing a comprehensive experimental design with five treatments and four replications. All treatments demonstrated increased ear count and weights of ear, silk, husk, edible cob, and biomass compared to the control. The study highlights the potential of Klebsiella quasipneumoniae inoculation in synergy with reduced nitrogen fertilizer to enhance total N contents in soil and positively impact baby corn yield and cob quality parameters. Optimal results were achieved with a 50% reduction in nitrogen fertilizer (150 kg N ha-1), emphasizing the importance of integrated nutrient management. The findings contribute valuable insights to sustainable agriculture, offering a promising strategy for increased baby corn production, improved nutritional quality, and environmental conservation. This integrated approach, involving microbial inoculation and nitrogen management, emerges as a key element in modern agricultural practices, promoting both productivity and nutritional content in baby corn crops.
