“…On the other hand, phosphorus helps plants to grow prolifically therefore reduces the toxicity of Fe and Zn by decreasing their concentration due to dilution effect [24]. Phosphorus also promotes Zn deficiency by precipitating Zn in soil [25].…”

Earlier, the agriculture system was oriented more towards achieving higher agronomic yields than the nutritional quality of food. Green revolution significantly enhanced the crop production primarily rice, wheat and maize production was boosted to meet the energy needs of growing population. As a consequence of the predominance of cereal-based staples that are fundamentally low in micronutrients, specifically Zn and Fe, more than 2 billion people worldwide suffer from an insidious type of deficiency known as micronutrient malnutrition. Just moderate amounts of micronutrient malnutrition can affect cognitive development, reduce disease resistance and increase the risk of women dying during childbirth. The approach to micronutrient fertilization has been shown to improve the yield and nutritional content of the staples. Agronomic biofortification provides an immediate and effective method to enhance accumulation of micronutrients especially Zn and Fe in cereals. An adequate amount of plant available micronutrients is a prime requisite to ensure adequate nutrient uptake. Most of the cereals are grown in soils deficit in Zn and under reduced conditions of rice ecosystem, its availability is decreased due to formation of less soluble Zn complexes with sulphate and carbonate. The form of fertilizer used, timing and method of application is critical for the enhancement of the grain quality of Zn and Fe. The effectiveness of agronomic biofortification can be enhanced by application of synthetic chelated micronutrient fertilizers and/or organic fertilizers fortified with micronutrients in combination with NPK ensuring proper nourishment of crops with adequate nutrient supply by slow release of nutrients in soil solution. Further, the response of foliar application has shown better results than soil application. Previous studies suggest that Zn fertilization not only enhances Zn concentration in grain but also improves the overall performance of maize crop. Agronomic biofortification of crops is advantageous in terms of accessibility, rapid result, ease in application and high sustainability.

“…Suggested foliar spray of 2 percent N at flower initiation along with chemical fertilisers and FYM coupled with opening of shallow furrows between 2 rows to reduce drought and nutrient stress in pigeon-pea crop. Foliar kaolin spray (6 per cent) with FYM + dust mulch produces desirable changes in the productivity of pigeon pea + mung bean intercropping in addition to reducing evapotranspiration losses, weed suppression and soil moisture retention [21].…”

One of the main abiotic constraints that limits pulse production is nutrient imbalance. Pulses play very important role in human diet providing all nutritional and physiological beneficial effects on human health. Pulses are rich in protein, carbohydrates, and dietary fibre, and a rich source of other bioactive components, and their consumption extends worldwide. Pulses are dried legumes that consist of various varieties of beans, lentils, peas, green gram, black gram, horse gram, and chickpeas. Protein-rich pulses are considered a primary food for a large portion of the Indian population, which satisfies everyone's protein and energy demands. Phosphorus and Fe have significantly enhanced pulse crop productivity in many pockets in response to potassium application. The production of both applied and native P is increased by phosphatic fertilisers and the use of bio-fertilizers. Some micro-nutrient foliar nutrition proved to be very successful, the amount and mode of application is determined by indigenous nutrient supply. Balanced nutrition is vital for achieving higher productivity. At the same time, in order to 'increasing nutrients demand, there is immense need to exploit the alternate source of nutrients viz Organic materials and bio- fertilisers for sustainable productivity with more environmentally friendly systems for the management of nutrients. Environmental issues and other hazards arising from the imbalanced use of nutrients should also be addressed properly. several investigators reported that integrated use of chemical fertilizers with organic manure is becoming a quite promising practice not only for maintaining higher productivity but also for greater stability to crop production as well as make the pulses become healthy to feed the population.

“…Agricultural production systems may not be defensible for well-managed conservation, they should be considered and planned, particularly for the first years, before the soil seed bank assembly has been predominantly depleted during tillage years. Although accessing weed control is a challenge, scientific studies have testament to the fact that minimal and no-tillage invoke weed population shifts particularly with regard to perennial weeds, creating a timehonored weed problem [4]. The same applies to annual weeds like Kochia (Kochia scoparia (L.) Schrad.)…”

Agriculture conservation practices such as minimal soil disturbance, permanent soil covering by crop residues or cover crops, and crop rotations leads to higher farm productivity. Although conservation agriculture has been adopted in India since its inception, it has now been successfully used in Indo Gangetic Plains irrigated rice-wheat cropping systems and has recently been made known in parts of central India. In conservation agricultural system, cover crops play an important role in weed control, but their adoption level is still limited Changes in tillage practices, planting schemes, and other management techniques can change the soil environment and trigger a significant change in weed flora In intense tillage operations early season weed control could be obtained by turning the soil, which disrupts the germination of weed seeds and the growth of seedlings through burial. In addition, soil-administered herbicides that do not need to be manifested can have less persistence and efficacy in the presence of plant residues that can hinder and bind the chemical before it reaches the soil surface. Selective herbicide compounds that are effective on weed species and not on a specific crop, conferring non-selective herbicide tolerance on a crop may be enormously effectual for potent weed control.
