Nutripellet pack is a tubular assembly composed of fertilizer pellet, manure pellet and bioinoculants. A laboratory electrolyte release study was conducted to assess the extent of nutrient enrichment by nutrient release from encapsulated fertilizer pellet. Nutripellet pack and fertilizer pellet pack was placed in soil, within a closed container. Periodically the entire soil was removed for the estimation of soil reaction (pH), electrical conductivity (EC) and available forms of N, P and K up to 11 weeks after incubation (WAI).  Before the analysis the residual encapsulated pellet was removed. The treatments comprising the sources of fertilizers (N for urea, P for DAP or SSP and K for MOP), levels of nutrient release pore (0, 25 micro pores) in fertilizer pellet and Nutripellet pack (fertilizer pellet + manure pellet) placement in sand, red soil and hill soil. High available N, P and K observed with Nutripellet pack with NP (DAP) K was registered in sand, red and hilly soils.

during samba (August-December) seasons of 2012 and 2013 to find out the optimum crop geometry, age and number of seedlings on growth and physiological characters in relation to yield of low land rice. The experiment consisted of three mainplot treatments viz., M 1 -25 x 25 cm, M 2 -25 x 20 cm and M 3 -25 x 15 cm and six sub-plot treatments S 1 -14 day old seedlings (DOS)+1 seedling/hill, S 2 -14 DOS+2 seedlings/hill, S 3 -14 DOS+3 seedlings/hill, S 4 -21 DOS+1 seedling/hill, S 5 -21 DOS+2 seedlings/hill and S 6 -21 DOS+3 seedlings/hill and replicated thrice in a split plot design. The treatment combination of M 3 S 5 (25 x 15 cm spacing and 21 DOS with two seedlings hill -1 ) recorded higher nitrogen uptake than others at panicle initiation, flowering and harvest stages. The same trend was followed on phosphorus and potassium also.

While the world's population is growing exponentially, there is an alarming increase in the need for food, which might reach a record nine billion people by 2050. In order to address the issue of rising food demand, a number of initiatives are being put into place to boost crop output and safeguard them against agricultural pests. The growing population pressures agricultural civilization to develop fresh strategies for boosting crop output. For nations all across the world, the issue of poverty and malnutrition has grown to be of great concern. Progress in the agricultural sector, which provides the raw materials for the food and feed industries, is crucial for both economic development and population expansion. With economic development, the soil nutrient balances are differed. Soil fertility is important in developing countries for assisting the economy and agriculture. There is a high demand in the twenty-first century for efficient, reliable, and cost-effective systems for detecting, supplying, monitoring, and diagnosing biological host molecules and nutrients. Traditional farming methods are incapable of keeping up with the rate at which food needs are increasing, so we must rely on and incorporate nanotechnology in agriculture and related sectors. In modern agriculture, increasing agricultural productivity is impossible without the use of chemical fertilizers and pesticides; however, the majority of agrochemicals are not eco-friendly and are thus harmful to human health. Nanotechnology is a novel technique for improved and sustainable agricultural production and also harbours a good capacity to bring novel alterations in the agricultural systems. Nanotechnology introduces new technologies and materials for use in molecular biology for the identification of plant pathogenic microorganisms. By bringing novel methods for distributing nutrients through nano fertilizers, specialized pathogen-targeted treatment, and boosting plant pest-resistance, nanotechnology has the potential to change the agricultural industry. Moreover, it can increase plants' ability to absorb nutrients and to endure environmental stresses. The fertility of the soil is a key factor in helping the economy and agriculture in developing nations. The benefits of strategies using nanotechnology for sustainable agriculture are covered here.
