Abstract This experiment considers the seven different stages of textile dyeing effluents on tomato crop production in order to diminish the excess effluent treatment plant (ETP) cost and farmers net input cost. Seven different stages waste water (WW) with ground water (control) were collected and analyzed for physiochemical as well as heavy metals properties. T8 (mixed effluent) crossed the limit of agricultural standard for almost all physiological parameters such as TDS, TSS, EC, BOD, COD affording the highest value. T8 also delivered the highest cl- and heavy metals like Cd, Ni, Cr followed by T4 (2nd wash after bath drain) < T7 (Fixing treatment water). As a consequence, these provided comparatively higher enrichment factor (EF), pollution load index (PLI) and sodium absorption ratio (SAR) to transform fresh soil into “severe” and “slightly to moderate” saline. Correlation matrix demonstrated that EF and PLI of heavy metals (except Cd, Ni) were negatively related to yield, while positively related to SAR and fruit abortion. Although T6 (2nd wash after soaping) performed better in respect to growth, yield, yield attributes and nutrient use efficiency, principal component analysis (PCA) expressed that T2 (2nd wash after scouring and bleaching) and T3 (enzyme treated water) also belong to T6 and T1 group (ground water). Therefore, T2, T3 and T6 could be used to vegetable crop production up to some extent and to reduce ETP and agricultural input cost.

Since the Green Revolution era, the farming sector exploited the soils for food, fiber, fodder, etc., with high input responsive varieties that excavated vast amounts of chemical fertilizers. The burgeoning population of the country calls for a commensurate increase in food production to satisfy the demands of its inhabitants. Further, due to innovative mechanization in agriculture, specialization, and government policy programs, the productivity of food has soared. Subsequently, it ensued greater productions and minimized food prizes. Regrettably, intensive agricultural operations degraded the soil quality and now reached such a stage where without external inputs, growers unable to achieve their targeted yields. India has lost 68% innate productive capacity of agricultural soils. This plunder of land’s quality continues unabated, further resulting in low nutrient use efficiency and insufficient yields of agroecosystems. Therefore, this is high time to realize the dreadful impacts of intensive crop production on the natural ecosystem. Irrefutably, both soil and its nutrients are the wondrous gifts of nature to humankind; utilizing them sustainably is imperative. The present chapter highlights the impacts of non-judicious nutrient management on soil productivity, nutrient use efficiency, and novel technologies required to promote sustainable agriculture and achieve the target of doubling farmer’s income in India.

Enhancing nutrient use efficiency (NUE) with minimal threat to environment has become critical for our agriculture food production systems (FPS) to sustain the burgeoning population. Nanotechnology with nanoscale inputs for production of nano agri-inputs (NAIPs) has emerged as an innovative solution for addressing issue of low or declining nutrient use efficiency (NUE) with minimal environment footprint. Nanotechnology is a promising field of research which has the potential to offer sustainable solutions to ever pressing challenges confronting our modern intensive agriculture. Nanotechnology employs nanomaterials which typically have small size (1–100 nm) which imparts unique characteristics and benefits. In addition to numerous other benefits, large surface area to volume ratio offers opportunity for better and effective interaction of nanoparticles to target sites. Nano-fertilizers hold potential to fulfil plant nutrition requirements along with imparting sustainability to crop production systems and that too without compromising the crops yield. Indian Farmers Fertilizer Cooperative Limited (IFFCO) - the farmers’ own fertilizer cooperative has been in the forefront for promotion of agro-technologies and novel agri-inputs to mitigate problems faced by the farmers. It has indigenously innovated at its Nano Biotechnology Research Centre (NBRC) at Kalol, Gujarat and succeeded in R& D and manufacturing of proprietary nano-fertilizers viz. nano urea, nano zinc, and nano copper. These nano-fertilizers utilize the dynamics of shape, size, surface area and bio-assimilation. There efficacy was evaluated on the basis of multi-location multi-crop trials under varying crop seasons, both by the research institutes and also on the progressive farmers’ fields across 11,000 locations on 94 crops across India. Independently, nano nitrogen, nano zinc, and nano copper have also been tested for bio-efficacy- bio safety- toxicity and environment suitability. IFFCO nano-fertilizers meet alll the current national and international guidelines related to nano technology or nano scale agri-inputs.They are in sync with OECD testing guidelines (TGs) and “Guidelines for Testing of NAIPs and Food Products” released by the Department of Biotechnology, Government of India. Harvested produce of crops applied with IFFCO nano-Urea, nano-zinc, and nano-copper have been found fit for consumption with no adverse effect. This paper reviews the benefits of nanofertilizers (Nano N, Nano Zn and Nano Cu) towards increasing nutrient use efficiency and crop productivity and produce quality in general and the journey of IFFCO nano-fertilizers (IFFCO’s Nano Urea, Nano Zn and Nano Cu) from conception to PILOT to PLANT stage has also been covered in this paper.

Nutrient use efficiency (NUE) is an important concept in the evaluation of crop production systems. With emerging nutrient deficiencies under intensive agriculture, there is a need to improve NUE. One of the approaches to enhance it is by judicious use of fertilizers (adequate rate, effective source, methods and time of application) as well as inclusion of organic manures. Organic nutrient sources are very effective but as their availability is not sufficient to meet the nutrient demand, we have to integrate both organic and inorganic sources of nutrients together in order to achieve higher NUE. Common measures of NUE include Partial Factor Productivity (PFP), Agronomic Efficiency (AE), Apparent Recovery Efficiency (RE), Physiological Efficiency (PE) and Internal Utilization Efficiency (IE). Mineral Fertilizer Equivalent (MFE) is another parameter that can be used to assess short term release of nutrients (mainly nitrogen) from organic nutrient sources

A study was taken up during 2014-16 for evaluating the potential of an organic package of practice towards integrated crop production (green farming) in comparison to conventional farmers’ practice in West Bengal, India. Under green farming, compost was integrated with chemical fertilizer for soil management while organic plant/ pest management was undertaken utilizing Inhana Rational Farming (IRF) Technology. The study indicated higher yield (9.7 %), higher nutrient use efficiency and economic sustainability under green farming irrespective of study area or potato variety. Higher qualitative expression in terms of starch content, pulp pH, vitamin C etc. under green farming might be due to the organic plant management aimed at energization of plant biochemical functions. Soil quality development as noted under green farming might have been influenced by the on-farm produced compost containing rich self- generated micro flora (in order of 10<sup>16 </sup>per colony forming unit.). The study indicated that green farming may serve as an efficient substitute of conventional farming towards yield sustenance, abatement of food toxicity and quality end product; through higher use of renewable energy and activation of plant physiological functions.
