“…The grain yield of wheat was significantly increased by combined effect of organic and inorganic sources of nutrients. Similar results were reported by Singh et al (2011) and Chuan et al (2013). It is evident from the data ( Table 1) that harvest index of wheat was not affected significantly with different doses of NPK with wellgrow formulation of soil and grain.…”

Effect of concentrate organic manure (wellgrow grain and wellgrow soil) and NPK improved the growth and yield of wheat. Significant improvement in terms of growth parameters like plant height, tillers, dry matter production and productive tillers with application of 120 : 60 : 60 NPK + 300 kg wellgrow soil/ha and at par with application of 120 : 60 : 60 NPK + 300 kg wellgrow grain/ha, treatment receiving 100% NPK + 300 kg wellgrow soil/ha resulted maximum grain yield (4545 kg /ha). Treatment of 100% NPK + 300 kg wellgrow grain/ha maintained higher straw yield (5715 kg/ha) and test weight (44.10 g) due to application of 100 % NPK along with 200 kg wellgrow soil/ha whereas it was at par with application of 75 and 100% NPK with both levels of wellgrow formulation.Wheat (Triticum aestivum L. Poaceae) is the world's leading cereal crop cultivated over an area of about 651 mha making it the third most-produced cereal after maize and rice. The integrated use of concentrate organic materials and inorganic fertilizers has received considerable attention in the past with a hope of meeting the farmer's economic need as well as maintaining eco-friendly conditions on long-term basis (Kumar et al. 2013). Regular use of a reasonable dose of organic manure, along with crop residue recycling, is known to cater the nutrient requirements of a low to medium intensity rice-wheat cropping system (Coventry et al. 2011). However, most of the long-term INM field research in South Asia pertains to rice-wheat system (Kumar and Dhar 2010). The integrated nutrient management helps to restore and sustain fertility and crop productivity together with economy and efficiency of fertilizer. Wellgrow is a plant product formulation in grain and powder forms produced by an Indian Tobacco Company (ITC). Hence, in the present investigation the effect of different doses of wellgrow formulation and NPK fertilizers on growth, yield and yield attributes of wheat was studied.A

“…Cassman et al (1996) suggested that < CC (1.1) < NC (1.7) < EC (5.7) < NE (9.3) ( Table 2). The values of AE (in kg kg A study in China showed that the indigenous nutrient supply was much higher than previously determined, indicating that over-application of fertilizers in many regions of China had increased both residual nutrients and the potential for losses into the environment (Chuan et al, 2013). Fan et al (2013) observed that higher yields in control plots led to a higher relative contribution of inherent soil productivity to the total production.…”

“…Fan et al (2013) observed that higher yields in control plots led to a higher relative contribution of inherent soil productivity to the total production. A high indigenous nutrient supply in relatively high fertility soils generally resulted in high relative yield (GYo/GYf) but low yield response to fertilization and low agronomic fertilizeruse efficiency (AE) (Chuan et al, 2013). In contrast, a low indigenous nutrient supply in relatively low fertility soils could result in low relative yield but relatively high yield response to fertilizer application and high AE (Zeng et al, 2012).…”

A major challenge facing China is to meet the increasing food demand of its growing population in the face of decreasing arable land area, while sustaining or improving soil productivity and avoiding adverse environmental impacts from intensive agriculture. This study uses data from China Statistical Yearbooks to analyze trends in regional soil productivity and grain yields in the major grain-producing regions in North China (NC), Northeast China (NE), East China (EC), Central China (CC), and Southwest China (SW), associated with regional fertilizer use and annual climate variation in rainfall and mean temperature over the 20 years. During 1992-2012, the average fertilizer increase rates (in kg ha -1 year -1 ) were in the order of regions CC (6.6) > NC (4.8) > EC (2.4) > SW (2.1) > NE (1.3), while yield responses to fertilizer use (with regression model coefficients, in kg kg -1 ) were in the order: SW (-0.9) < CC (1.1) < NC (1.7) < EC (5.7) < NE (9.3), showing higher yield responses to fertilizer use for NE and EC than for other regions. The changes in regional grain yields also showed higher yield responses to soil-based productivity for NC, CC, and SW, or to annual climate variability for CC than for other regions, indicating that other factors (such as inherent soil productivity or annual climate variability could be more important than fertilizer in affecting yields. The strategies for regulating nutrient management are needed considerably based on regional indigenous soil nutrient supply under varying regional climate conditions.

“…The determination of fertilizer N requirements was mainly based on expected yield response to fertilizer and target agronomic efficiencies of applied N (AE N ). The determination of fertilizer P and K requirements considers the internal efficiency combined with estimates of attainable yield, nutrient balance and yield responses to the added nutrient within specific field (Chuan et al, 2013b;Pampolino et al, 2012). The P and K balances were estimated and used to predict the residual P and K resulting from the previous crop.…”

“…A large dataset (n = 5000) from field experiments were collected from 2001 to 2010 to estimate balanced nutrient requirements used QUEFTS model (Xu et al, 2013). Understanding nutrient uptake at target yield contributes to optimize fertilizer rate, calculate nutrient balance and helps to lessen pollution from fertilizer application (Chuan et al, 2013b;Xu et al, 2014).…”
