Agronomic Biofortification

Agronomic biofortification increases the concentration of target mineral in edible portions of crops by the use of mineral fertilizers to increase dietary intake of target minerals. Among these iron and zinc deficiencies in human nutrition are noticed in countries where maize is the staple food. The objective of this study was to evaluate agronomic biofortification performance in association with Integrated Nutrient Management in maize (Zea mays .L). The study was conducted under field conditions in Chinnakandiankuppam village, Vriddhachalam Taluk, in the North-eastern region of Tamil Nadu state, India of Kharif 2020 season. Two hybrids in main plots (M1 – Non biofortified and M2 – Biofortified) were combined with six treatments in sub-plots (100 % RDF through NPK (S1), 100 % RDF through FYM (S2), 50% RDF through NPK + 50% through FYM (S3) as soil application, S1+ Zinc + Iron (S4), S2 +Zinc + Iron (S5) and S3 + Zinc + Iron (S6) as foliar application with evaluations were carried out in wet season period of the year. Application of 50 percent RDF through NPK + 50 percent RDF through FYM with Fe, Zn, foliar applications (S6) was the most efficient agronomic biofortification practice for growth attributes, yield and yield attributes, nutrient uptake, and quality parameters for the maize cropping system under the irrigated condition of the northeastern zone of Tamilnadu State, India.

This study aims to determine the effect of biochar dosage and compost fertilizer and its interaction on the growth and yield of corn crops. This experiment used a randomized block design (RBD) with a factorial pattern consisting of 2 factors. The first factor was the dose of biochar (B) consisting of 4 levels, namely: 0 ton ha-1 (B0), 5 ton ha-1 (B1), 10 ton ha-1 (B2), 15 ton ha-1 (B3). The second factor is the dosage of compost fertilizer (K) consisting of 2 levels: 0 ton ha-1 (K0), and 20 ton ha-1 (K1). The results showed that the interaction between the treatment of biochar dose and compost fertilizer had no significant effect on all observed variables. Biochar and compost treatment have significant effect to most observed variables, except on leaf area and harvest index have no significant effect. Treatment of biochar with a dose of 10 ton ha-1 gave the highest dry kiln seedlings weight of 7.83 tons increased by 35.60% compared to the lowest dose without biochar of 5.77 tons. Treatment of compost doses of 20 ton ha-1 gave the highest dry seed oven per hectare weight of 7.42 tons increased by 16.60% when compared with the lowest yield on treatment without compost dose as much as 6.37 tons.

Randomized Block Design

The present investigation was conducted using 28 different genotypes (seven parents and their 21 F1s) of maize under organic conditions at the Rain-fed Organic Research Farm, Narayanbag, Institute of Agricultural Sciences, Bundelkhand University, Jhansi (U.P.) India, during kharif 2018 and rabi season 2018-19. In order to determine the general and specific combining ability of parents and the crosses, the growth parameters and yield components were evaluated in a 7×7 diallel fashion in maize in a Randomized Block Design (RBD) with three replications. In this study, the GCA effects suggested that parent P1, P2 and P4 were the most desirable as they possessed high GCA effect for most of the characters. Among F1 crosses, P4 x P3, P3 x P1, P5 x P3 and P7 x P5 having significant positive SCA were found to be desirable for yield and yield attributing characters. The maximum heterotic effects in desirable direction for yield attributes were showed by the cross combinations viz; P1 x P6, P2 x P7, P2 x P5, P1 x P2, P3 x P4, P5 x P7 and P3 x P5. The maximum heterosis was recorded in for Seed yield per plant P5 x P7 (39.32%) which ranged from -14.69 to 49.55.

Four Levels

Plant nutrients and soil moisture are considered some of the most important factors affecting physiological characters and grain yield of maize. Therefore, a field experiment was conducted at UBKV, Cooch Behar, West Bengal during 2013 and 2014 to study the effects of moisture conservation and nutrient management practices on growth and yield of maize (Zea mays L.). The experiment was laid out in a split –plot design with three replications. Four levels of moisture conservation practices M0: without irrigation and without mulch, M1: irrigation as and when required, M2: dry weed biomass mulch @5.0t ha-1 M3: FYM mulch @ 5.0 t ha-1 were assigned to main plots and four levels of nutrient management N1: 100% RDF 80:40:40 kg ha-1 of N:P2O5: K2O N2:100% RDF + phosphate solubilising bacteria (PSB) + Azotobacter N3:75% RDF+ PSB + Azotobacter + vermicompost (VC) @ 5.0 t ha-1 and N4:50% RDF + PSB + Azotobacter + 50% vermicompost @ 2.5t ha-1 for sub plot. Among the moisture conservation practices, application of irrigation recorded the highest growth, yield attributes, yield and harvest index followed by FYM mulch and dry weed bio-mass mulch. Similarly, N, P and K uptake of maize was recorded highest under irrigation followed by FYM mulch; dry weed bio mass mulch and lowest N, P and K uptake were recorded under without irrigation and mulch. Among the nutrient management practices the highest growth, yield attributes, yield, harvest index and N, P & K uptake were recorded under 75% RDF + PSB + Azotobacter + vermicompost @ 5.0 t ha-1 followed by 100% RDF + PSB+ Azotobacter & 100% RDF and lowest were recorded under 50% RDF + PSB + Azotobacter + 50% vermicompost 2.5 t ha-1 . Likewise, maximum benefits were recorded under 75% RDF + PSB+ Azotobacter + vermicompost @ 5.0 t ha-1 and lowest net return and return per rupee invested were recorded under 50% RDF + PSB + Azotobacter + 50% vermicompost 2.5 t ha-1. From this study, maize grown with irrigation and supplied with 75% RDF + PSB + Azotobacter + vermicompost @ 5.0 t ha-1 is found the best for obtaining overall gain on a sustainable basis.
