A field experiment was conducted during the winter seasons of 2007-08 to 2009-10 at Jobner, India on loamy sand soil to evaluate the effect of integrated nutrient management on growth, productivity and economics of fenugreek (Trigonella foenum-graecum). The experiment consisted of fourteen combinations of integrated nutrient management practices for application of recommended dose of nitrogen (RDN) to fenugreek i.e., 40 kg/ha, through different sources, viz., control, inorganic or organic [farmyard manure (FYM), poultry manure (PM), vermicompost (VC) and neem cake (NC)] alone or in combinations was laid out in randomized block design with three replications. Based on three years of study the results revealed that application of all nutrient management treatments through organic and inorganic sources alone or in combination brought significant effect on growth, yield and economics of fenugreek. Further the results revealed that integration of 50% RDN through vermicompost (VC) + 50% RDN through inorganic source to fenugreek recorded higher plant height, branches/plant, pods/plant, seeds/pod, test weight, seed yield (1781 kg/ha), stover yield (3392 kg/ha), biological yield (5173 kg/ha) and net returns (Rs. 52151/ha). However, maximum benefit cost ratio was fetched with application of 100% RDN through inorganic source.

A field experiment was conducted to study the effect of long-term integrated nutrient management (INM) on growth, yield and nutrient uptake of rainfed finger millet during kharif 2019 at field unit of All India Co-ordinated Research Project for Dryland Agriculture at University of Agricultural Sciences, Bangalore, India. The experimental plot in the field was laid out in a randomized complete block design (RCBD) with 10 treatments and four replications. Growth parameters such as plant height (112.44 cm), number of productive tillers per hill (4.75), number of ear heads per hill (4.49), number of fingers per ear head (7.25), total dry matter production per hill (77.39 g) and yield parameters like grain yield (28.27 q ha-1) and straw yield (32.63 q ha-1) were found to be higher with application of FYM @10 t ha-1 + 100% RDF under finger millet- groundnut rotation (T9). Similarly, T9 also recorded higher uptake of nitrogen (37.03 and 26.40 kg ha-1), phosphorus (6.78 and 4.57 kg ha-1) and potassium (30.17 and 48.68 kg ha-1) in grain and straw of finger millet, respectively. It implies that INM over long period of time tend to supply the plants with sufficient amount of essential nutrient elements while creating favourable physico-chemical properties of soil for healthy environment. It also safeguards soil nutrient balance in long term to an optimum level for sustaining the desired crop productivity.

A field experiment was conducted during kharif 2011 on experimental farm of the College of Post Graduate Studies (CAU–Imphal), Umiam (Meghalaya) to evaluate the effect of integration of green manuring, FYM and fertilizers as integrated nutrient management (INM) practices on growth and developmental behaviour of quality protein maize cultivar QPM 1. The data revealed that comparatively higher amount of primary nutrients were added in green manured maize plots in comparison to non green manured treatments. Green manuring also left a positive response on plant height, CGR, RGR leaf area, and dry matter accumulation in plants though the difference between green manured and non-green manured treatments was at par. Treatments 75 % RDF + 5 t FYM ha-1, 50 % RDF + 7.5 t FYM ha-1, 100 % RDF ha-1 and 75 % RDF + 2.5 t FYM ha-1 recorded significantly higher values of all the above said growth parameters over 50 % RDF + 5 t FYM ha-1 and control treatments. At all stages of observations, the maximum dry matter was associated with RDF (recommended doses of fertilizers) which was at par with 75 % RDF + 5 t FYM ha-1, but significantly higher over the plant dry weight recorded from all remaining treatments. A Significant difference in CGR at 30 – 60 and 60 – 90 DAS stage and in RGR at 90 DAS - harvest stage was observed due to various combinations of recommended dose of fertilizer with different doses of FYM. Number of days taken to attain the stages of 50% tasselling, silking and maturity did not differ significantly due to green manuring. However, treatment 75 % RDF + 5 t FYM ha-1 took significantly lesser number of days for these stages than other treatment combinations. The superiority of the treatment 75 % RDF + 5 t FYM ha-1 indicated a possibility of substituting 25% of RDF with 5 t FYM ha-1 without any loss in dry matter accumulation in plants of the quality protein hybrid maize in mid-hill ecosystems of Meghalaya.
