Background: Investigations were carried out during Rabi, 2016 and Summer, 2017 at farmer’s field in Kodukkanpalayam village of Cuddalore District, Tamil Nadu to evaluate the direct effects of agro industrial wastes (bagasse ash, pressmud and distillery spentwash), crop residues, farmyard manure with 50% inorganic sources, with and without Rhizobia on various traits of groundnut. There were twelve treatments in randomized block design (RBD) with three replications. Results revealed that the growth and yield components of groundnut viz., plant height, DMP and LAI at flowering stage, number of pods per plant, hundred kernel weight, pod yield and kernel yield were greatly influenced by the treatments. Methods: Combination of Pressmud @ 12.5 t ha-1 + Rhizobia @ 2 kg ha-1 + 50% RDF (T7) recorded the highest and followed by the application of distillery spentwash @ 100 m3 ha-1 + Rhizobia @ 2 kg ha-1 + 50% RDF (T8). Similar trend of results was recorded in summer, 2017 also. This might be due to the increase in the availability of nutrients, which increased the growth and yield attributes of groundnut in both the seasons. Also, use of agro industrial wastes and biofertilizers in any cropping sequence minimize the cost of inorganic fertilizers, thereby act as a boom to farmers by making the waste into wealth and maintain the soil health and fertility. Result: The study revealed the scope of utilization of agro industrial wastes (bagasse ash, pressmud and distillery spentwash), organic sources (crop residues and FYM) and biofertilizer (Rhizobia) in Agriculture.

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.
