There are many management methods for nutrient which can be specifically applied in farming systems. Integrated nutrient management (INM) generally denotes the combined use of organic and chemical fertilizers for producing crops in a sustainable manner and to maintain soil fertility as well as to supply nutrient in appropriate amount which consider social, ecological and economic impacts. This paper shows the importance and need of INM in agriculture production. Also, the relation of INM and yield attributes are analyzed and evaluated including growth and physical attributes of cowpea. The status of nutrient uptake by plant is also described along with other physical and chemical properties of soil. Finally, this paper also describes about the biofertilizer and its relation, impact and effect on crop production which can be used as a improved technology with the combination of other nutrient management practices.

Soil Chemical Properties

A proper understanding of variability of soil chemical properties over an area is important for identifying the soil nutrients related production constraints. The suggestions for remedial measures and execution of appropriate nutrient management strategies are also based on the good knowledge of variation in soil nutrients. A case study was undertaken with an objective of assessing spatial variability of selected soil chemical properties of agricultural land. Soil samples from the surface (0 to 15 cm) were collected from farmers’ field in the central part of Kavrepalanchowk district of Nepal in February 2018. Soil samples were analyzed for soil pH, total organic carbon (TOC), total nitrogen (N), phosphorous (P), and potassium (K). Descriptive statistics revealed that the soil in the study area was slightly acidic and contained the low status of TOC, P, and K, while the N content was medium. Coefficient of variation (CV) indicated that soil pH was the least variable (CV= 9.37% with values ranging from 5.3 to 7.7) among the investigated soil samples while N was the most variable (CV= 98.81% with content values ranging from 0.03% to 0.67%). Other selected properties (TOC, P, and K) were found to be highly variable (CV= 49.94%, 94.89%, and 57.53% respectively). These variations in soil chemical properties were mostly related to the different cropping systems and soil management practices, including nutrient management carried out in the study area. Owing to the higher variability of nutrients, the results suggested to take into account various soil and nutrient management practices for sustained soil fertility and enhanced 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.

Background: A field experiment was conducted during two consecutive summer seasons of 2016-17 and 2017-18 at Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar, Gujarat to assess the residual effect of wheat varieties and integrated nutrient management on growth, yield, economics and quality of green gram (Vigna radiata L.). The soil of the experimental plot was loamy sand in texture, low in organic carbon (0.24%), available nitrogen (159 kg/ha) and Zn (0.41 mg/kg), medium in available phosphorus (38.90 kg/ha) and high in available potash (287 kg/ha). Methods: During the period 2016-17 to 2017-18 the experiment was laid out in a Factorial RBD with three replications, consisted of four varieties GW 273 (V1), GW 322 (V2), GW 451 (V3) and GW 496 (V4) and six integrated nutrient management control (N1), 100% RDF (N2), 100% RDF + Azotobacter + PSB (N3), 75% RDF + Azotobacter + PSB (N4), 75% RDF + Azotobacter + PSB + ZnSO4 (N5) and 50% RDF + 25% N through FYM + Azotobacter + PSB + ZnSO4 (N6). Result: The pooled results indicated that among the residual effect of nutrient management practices, application of 50% RDF (RDF; 120:60:00 kg NPK/ha) + 25% N through FYM + Azotobacter + PSB + ZnSO4 significantly improved growth parameters, yield attributes, seed yield (669 kg/ha) and stover yield (1406 kg/ha) over control and gained the highest net return (₹18538/ha) and benefit: cost ratio of 0.88.
