A Field experiment was conducted on sandy loam soil at Sabour during kharif season of 2018 to evaluate optimum plant geometry, graded fertility level and zinc level for yield and nutrients uptake of baby corn (Zea mays L.). Experiment was laid out in split–plot design and replicated thrice with three plant geometry viz. P1 (40X20 cm), P2 (50X15 cm) and P3 (paired row at 50+30 x20 cm) in main plot, three levels of graded fertility (kg NPK ha-1) viz. F1(120:60:60), F2 (150:75:75) and F3 (180:90:90) in sub plot whereas, two levels of zinc (kg zinc ha-1) viz, Z1 (2.5) and Z2 (5.0) in sub-sub plot. Significant increase in baby corn yield (14.34q ha-1), nutrient uptake of baby corn, fodder and soil nutrient status were recorded with paired row plant geometry. The baby corn yield (13.92q ha-1), green fodder yield (278.91q ha-1), nitrogen, phosphorus and potash uptake of baby corn, fodder and soil nutrient status was higher with fertility level 180:90:90 kg N P2O5 K2O ha-1. Higher level of zinc (5.0kg ha-1) had improved baby corn yield (13.38q ha-1), green fodder yield (277.7q ha-1) along with high uptake of nutrients and improved soil fertility status.

Effects of Non-Leguminous Cover Crops on Yield and Quality of Baby Corn (Zea mays L.) Grown under Subtropical Conditions

Effects of non-leguminous cover crops and their times of chopping on the yield and quality of no-till baby corn (Zea mays L.) were evaluated during two kharif seasons (May-August in 2014 and 2015) under subtropical climatic conditions of Punjab, India. The experiment was laid out in a split-plot design with four replications at Punjab Agricultural University’s Research Farm. Three cover crops (pearl millet (Pennisetum glaucum L.), fodder maize (Zea mays L.), and sorghum (Sorghum bicolor L.)) and the control (no cover crop) were in the main plots and chopping time treatments (25, 35, 45 days after planting (DAP)) in the subplots. During both kharif seasons, the yield (cob and fodder yield) and dry matter accumulation of baby corn following cover crop treatments, especially pearl millet, were significantly (p ≤ 0.05) higher than the control, and improved with increments in chopping time from 25 to 45 DAP. The effect of cover crops on baby corn quality (i.e., protein, starch, total soluble solids, crude fiber, total solid, and sugar content) did not differ among treatments, while increasing increments in chopping time had a significant effect on the protein and sugar content of baby corn. The use of cover crops and increment in chopping time helped in enhancing topsoil quality, especially available nitrogen; yet, the effect of cover crops and their times of chopping on topsoil organic carbon, phosphorus, and potassium did not differ among treatments. During both seasons, there was no significant interaction between cover crop and time of chopping among treatments with respect to baby corn yield and quality, as well as topsoil quality parameters.

Relative competency of urea in augmenting physiological and agronomic traits of baby corn (Zea mays)

Nitrogen is indispensable for aggrandizing productivity of crop but the losses associated due to swift transformation and release pattern are subjected to various losses leading to pitiful amount left for crop uptake, pollution and resource wastage. Present study was conducted to evaluate the efficacy of coated urea and nitrogen rates on baby corn growth, yield and NUE. The experiment comprised varieties PHM-1 and HM-4, coated urea (NCU, ZCU, SCU and PU) and nitrogen levels @180, 150, 120 kg N/ha along with the control. The study revealed that PHM-1 obtained significantly higher plant height, no. of cobs and weight of dehusked cob that led to significant increase of 18.47 and 19.67 % higher husked and dehusked cob yields over HM-4 which attained 12.6% higher fodder yield over latter. The baby corn cob yield and fodder yield were significantly higher in coated urea over prilled urea. The husked and dehusked yield of baby corn was higher in neem-coated urea over prilled urea by 14.81 and 14.37% respectively. H o w e v e r , a reduction of 59.9% in total fodder yield was recorded in control when compared to 180 kg N ha. Also, NPK uptake was higher then PHM-1 and uptake by coated urea was higher then prilled urea along with high uptake for 180 kg N/ha, further the AE and higher PE of baby corn cob was found highest in variety PHM-1 although for fodder, the higher AE was recorded in HM-4, whereas ANR was higher in PHM-1.

Effect of zinc application on growth and yield of baby corn (Zea mays L.) in lateritic soil of West Bengal

A field experiment was conducted during rabi season of 2017-18 at agricultural farm, Palli Siksha Bhavana, Visva-Bharati, Sriniketan, West Bengal, to study the “Effect of zinc application on growth, yield and economics of baby corn (Zea mays L.) in lateritic soil of West Bengal”. The experiment was laid out in Factorial RBD having two factors: one with two levels of soil application of ZnSO4; 0 and 25 kg ha-1 and other with four levels of foliar spray of ZnSO4; no foliar spray, 25 DAS, 40 DAS and twice at 25 DAS & 40 DAS. There were eight treatment combinations with each treatment replicated thrice. Soil application of ZnSO4 @ 25 kg ha-1 exhibited significantly higher growth attributes (viz. plant height, number of leaves/plant, LAI, dry matter accumulation, crop growth rate) and yield attributes (viz. number of cobs per plant, corn and cob weight, corn and cob length, corn and cob girth and also corn yield, cob yield, husk yield and green fodder yield) of baby corn, than no soil application of ZnSO4. Foliar spray of ZnSO4 applied twice at 25 DAS & 40 DAS gave the highest yield components and yield in baby corn. However, this was statistically at par with foliar spray of ZnSO4 at 40 DAS and 25 DAS. Combined soil application of ZnSO4 @ 25 kg ha-1 and foliar spray twice at 25 DAS & 40 DAS interacted significantly and produced higher number of cobs per plant, number of cobs per hectare of baby corn cultivation. This was at par with soil application of ZnSO4 at 25 kg ha-1 and foliar spray at 40 DAS and significantly higher than foliar spray at 25 DAS.

Yield and nutrient uptake of baby corn (Zea mays L.) Genotypes as influenced by crop geometry and fertility levels

A field experiment was conducted to study the effect of crop geometry and fertility levels on the yield and nutrient uptake of baby corn (Zea mays L.) genotypes. The experiment was laid out in split plot design with main plot factor comprising of 4 treatment combinations of crop geometry(S) and fertility levels(F) viz. S1F1(65cm × 16 cm, RDF), S1F2(65cm × 16 cm, 150%RDF), S2F1(65cm × 12 cm, RDF) and S2F2,(65cm × 12 cm, 150%RDF) and sub plot factor comprising of 2 baby corn genotypes (G) viz. G1(BC-18K-ZIII-1) and G2(BC-18K-ZIII-2). The combination of (S1F2)G2 recorded the maximum first baby cob yield and baby corn yield. The combination of (S1F2)G1 recorded maximum harvest index. The total N and K uptake was significantly higher for S2, F2 and G2 as compared to S1, F1 and G1, respectively. The P and K uptake for cob husk was maximum with the combination of (S2F2)G2.

Effect of nano NPK and straight fertilizers on yield, economics and agronomic indices in baby corn (Zea mays L.)

A field experiment was conducted in sandy clay loam soil at Campus Farm, M.S. Swaminathan School of Agriculture, R. Sitapur, CUTM, Paralakhemundi to study the fertilizer use efficiency of nano NPK and straight fertilizers with and without organic sources on baby corn (Zea mays L.) during winter of 2018-19. The experiment was laid out in randomized complete block design with three replications and 12 treatments. The treatments comprise of nano NPK, straight fertilizers and organics (vermicompost and azotobacter) applied as alone and combinations. The baby corn and green forage yield was significantly influenced by use of nutrient management treatments. Application of 125 % recommended fertilizer dose (RFD) as straight fertilizer through urea, single super phosphate and muriate of potash registered the maximum gross return (Rs. 412498.00/ha), net return (Rs.266528.00/ha) and B:C ratio (2.83). It was followed by application of 100 % RFD (SF) and 75% RFD (SF) + 25% recommended dose of nitrogen through vermicompost + Azotobacter. Amongst 12 treatment variables, the least performance was exhibited under control for all the parameters. Amongst different nutrients management treatments, the maximum partial factor productivity, agronomic efficiency and apparent nutrient recovery was recorded by application of nano NPK alone while nutrient use efficiency was the highest in 75 recommended fertilizer dose (Nano NPK) + 50 % (SF).

GGE biplot analysis of genotype × environment interaction and identification of mega-environment for baby corn hybrids evaluation in India

Baby corn has emerged as one of the most important sources to augment the farmer’s income in peri-urban areas. It has diverse uses as vegetables, snacks, value-added products and assured supply of green fodder for livestock. The multilocation varietal trials mainly emphasize on the identification of new superior cultivars over commercial checks, while genotype×environment interaction (GEI) is ignored. In the current study, 13 baby corn hybrids were evaluated for green ear yield, baby corn yield and green fodder yield over eight locations (environments) in kharif seasons of 2015 and 2016 using GGE biplot analysis. The results revealed a higher proportion of the variation in the data is attributable to the environment (72.4-87.0%), while genotype contributed only 2.5-7.3% of the total variation. GEI contributed 10.5-24.1% of the total variation. Superior stable hybrids for green ear yield, baby corn yield and green fodder yield could be identified using a biplot graphical approach effectively. ‘Which won where’ plot for each of the traits partitioned testing locations into three mega-environments with different winning genotypes for different traits in respective mega-environments. Thus it can be concluded that similar inferences can be drawn from one or two representatives of each mega-environment instead of using several locations. Hence, the presence of extensive crossover GEI in baby corn multi-location trials clearly suggests the need to emphasize on smaller zonation of testing locations and location-specific breeding. Particularly in baby corn, this is the first study on GGE biplot analysis to identify mega-environments for effective evaluation of baby corn trials.

Yield Performance of Organic Baby Corn (Zea Mays L.) as Influenced by Nutrient Management and Moisture Conservation Practices in Sandy loam Soils of Assam

A field experiment was conducted during the rabi season of 2016-17 to study the effect of nutrient management and moisture conservation practices on yield attributing characters, yield and economic return of organic baby corn grown in a sandy loam soil under rainfed condition. The experiment was laid out in RBD factorial design with three replications. PAC 321 was used as the test variety of baby corn. Among the treatments enriched compost @ 2.5 t ha-1 has shown the significantly better results with respect to yield attributing characters and cob yield followed by application of FYM @ 2.5 t ha-1+lime+ash (1000:10:1). Treatments with straw mulch @ 2 t/ha recorded significantly higher results with respect to different yield attributing characters, cob yield, green fodder yield and high monitary return with B:C ratio.

Performance of Baby Corn (Zea Mays L.) in Integration of Organic and Inorganic Nitrogen

Nitrogen (N) fertilization mostly determines the productivity of a crop. The supply of N can be ensured in both inorganic and organic means. Slowly released organic N can be combined with inorganic N to minimize the detrimental effect of chemical fertilizers to environment as well as to ensure the sustainable production. To observe the response of baby corn in integration of organic and inorganic N field experiments were conducted in N deficit soil in consecutive winter and summer. There were five nutrient levels as treatment in the experiment. The treatments used in the winter season were T1=N 0 kg + CD 15 t ha-1, T2=N 60 kg + CD 15 t ha-1, T3= N 90 kg + CD 10 t ha-1, T4= N 120 kg + CD 5 t ha-1 and T5= N 150 kg + CD 0 t ha-1 while in the summer season T1=N 30 kg + CD 15 t ha-1 varied and others remained same as in the winter season. The lowest cob yield without husk was found where minimum inorganic N was combined with organic N in both seasons. Plant received only N from inorganic source represented highest cob yield. Statistically similar yield was also obtained from one combination of inorganic and organic N (120 kg N + 5 ton CD ha-1), where the rate of inorganic N was 20% lower than that of sole inorganic N source. Between seasons, significantly positive yield response was recorded in winter irrespective of nutrient levels. Therefore, one fifth of inorganic N application can be minimized in terms of integrated N management from organic and inorganic sources without affecting potential yield of baby corn.

Effect of Different Levels of Water Soluble Phosphorus in Complex Fertilizers on Crop Productivity and Soil Health

Field experiments were undertaken on sandy soils with three cropping systems at Giridih, Jharkhand, India for two years during 2012-2014. The experiments were executed in split plot design by assigning water soluble phosphorus (WSP) fertilizers in main-plot and recommended dose of phosphorus (RDP) in sub-plot with three replications. The maximum economical yield of rice (4705 kg/ha), baby corn (842 kg/ha) and Chickpea (920 kg/ha) were recorded with the application of 30% WSP. The maximum economical yield of successive crops - wheat (3185 kg/ha), mustard (1720 kg/ha) and groundnut (1578 kg/ha) were recorded with the application of 30% WSP and 100% RDP treatment. Almost similar trends were noticed in terms of by-product yield, nutrient uptake and residual soil fertility status. All the levels of WSP (30% - 89%) in complex fertilizers were found to be equally effective for grain yield, straw yield, nutrient uptake, and residual soil fertility.

Effect of Different Organic Manures on the Yield, Nutrient Uptake and Quality of Baby Corn

A field experiment was conducted at Agricultural College and Research Institute, Killikulam during Purattasipattam (September - October) of 2017 to study the effect of different organic manures on the yield, nutrient uptake and quality of baby corn. Baby corn G 5414 was used as test variety. The experiment was laid out in randomized block design with three replications. Treatments consisted of three different organic manures viz., farmyard manure, poultry manure and vermicompost with or without panchagavya as foliar spray. Significantly, the highest green cob and green fodder yield was obtained with the application of 100% N through poultry manure (10920 kg ha-1 and 29797 kg ha-1, respectively) and it is superior to the rest of treatments. Application of 100% N through poultry manure + 3% Panchagavya spray at vegetative and tasseling stage recorded higher green cob and green fodder yield (10418 kg ha-1 and 28636 kg ha-1, respectively). This was followed by the application of 50% N through farmyard manure + 50% N through poultry manure + 3% Panchagavya spray at vegetative and tasseling stage and application of 50% N through farmyard manure + 50% N through poultry manure which registered higher green cob and green fodder yield (10401 kg ha-1 and 28498 kg ha-1, respectively, 10354 kg ha-1 and 28389 kg ha-1, respectively). These treatments were on par with each other. Higher nutrient uptake (NPK) and quality of baby corn was obtained with the application of 100% N through poultry manure. Higher gross return, net return and B: C ratio was recorded with the application of 100% N through poultry manure (` 248197 ha-1, ` 199647 ha-1 and 5.1, respectively). Application of 100% N through poultry manure was found to be the desirable organic nutrient management practice for realizing higher yield, nutrient uptake and quality of baby corn.

Response to different levels of spacing, nitrogen and plant growth regulators

An experiment was conducted during kharif season, 2010 and 2011 at Rajasthan College of Agriculture Udaipur, to study the effect of crop spacing (45cm × 20cm, 60cm × 15cm and 90cm × 10cm), nitrogen levels (60, 90 and 120 kg ha-1) and plant growth regulators (control, NAA @) 40 ppm and Mepiquat chloride @ 200 ppm) on yield, nutrient content and uptake of baby corn. The higher green cob yield, baby corn yield and green fodder yield was significantly recorded at 60cm × 15cm spacing over 90cm × 10cm. Increasing nitrogen levels up to 90 kg ha-1 showed marked improvement in green cob yield and baby corn yield, but in case of green fodder yield, nitrogen concentration and uptake by fodder recorded significantly highest with 120 kg ha-1. The crop sprayed with Mepiquat chloride @ 200ppm produced the highest green cob yield (5903.03 kg ha-1), baby corn yield (2082.64 kg ha-1) and this was comparable with application of NAA, in case of green fodder yield NAA @ 40 ppm produced significantly higher green fodder yield (26.88 t ha-1) over Mepiquat chloride @ 200 ppm which produced lowest green fodder yield (22.13 t ha-1).
