A field experiment was carried out at the Central Research Farm, Bidhan Chandra Krishi Viswavidyalaya, West Bengal, India to study the effects of integrated nutrient management on the nutrient accumulation (dry weight recoveries) in brinjal and plant nutrient status of the post- harvest soil of brinjal under Nadia conditions. The results revealed that the treatment consisting of 75% RDF (RDF i.e. N:P:K:: 125:100:50) + Azospirillum + phosphate solubilising bacteria (PSB) + Borax @ 10 kg ha-1 recorded the highest oxidizable organic carbon (8.049 g kg-1), total nitrogen (1.05 g kg-1) , available nitrogen (212.67g kg-1), available phosphorus (76.20g kg-1) and available potassium (177.59 g kg-1) in the post harvest soils of brinjal. On the other hand, 75% RDF + Azospirillum + PSB + FeSO4 @ 50 kg ha-1 recorded the highest available iron (26.14 kg ha-1) and the treatment consisting of 75% RDF + Azospirillum + PSB + ZnSOâ‚„ @ 25 kg ha-1 recorded the highest soil available zinc (7.62 kg ha-1) while 75% RDF + Azo + PSB + Borax @ 10 kg ha-1 recorded the highest available Boron content (0.78 kg ha-1) of the post harvest soil of Brinjal. Highest brinjal yield (14.96 t ha-1) was supported by the treatment consisting of 75% RDF + Azospirillum + PSB + Boron @ 10 Kg ha-1. Meager information was available regarding the performance of integrated application of organics and micronutrient on brinjal in the experimental location. The present study may enlighten this unexplored section of nutrient management in brinjal.

An experiment has been conducted under AICRP on Soil Test Crop Response (STCR) at the Central Research Farm (Gayeshpur), Bidhan Chandra Krishi Viswavidyalaya, West Bengal to find out the effect of integrated nutrient management in ArkaHarit variety of bitter gourd. The treatments contain different organic and inorganic fertilizer viz. Control (T1), NPK @ 90:60:60 kg/ha (T2), Vermicompost @ 12t/ha (T3), NPK+ Vermicompost @ 3t/ha (T4), FYM @ 25t/ha (T5), NPK+FYM @ 6.25t/ha (T6), Mustard oil cake (MOC) @ 7t/ha (T7), NPK+MOC @ 1.75t/ha (T8). Application of organic and inorganic sources in an integrated manner has resulted higher in yield, physical and chemical parameter such as seed yield (2815 kg/ha), aggregate ratio (0.69), mean weight diameter (0.593 mm), geometric mean weight diameter (0.679 mm), organic carbon (1.28 %), CEC (12.88 meq/100g), available nitrogen (208 kg/ha), phosphorus (62 kg/ha), potassium (167 kg/ha) in higher magnitude as compare to the single application of inorganic fertilizer. In maximum cases, the chemical parameters is highest in harvesting stage rather than other stage. Quality characters such as Vitamin A, C, crude fibre are nourished in favourable way due to integrated appli-cation of organic and inorganic fertilizers. Based on the performance, it was found that treatment combination of NPK+MOC @ 1.75t/ha (T8) was best among all treatments in most cases for yield, productivity and nutritional as-pects of ArkaHarit variety of bitter gourd.

Brassica oleracea var. botrytis L. (Cauliflower) is an important commercial vegetable crop grown all over the world. In order to meet the growing demand of burgeoning population, large amounts of herbicides, pesticides and fertilizers are being applied to the fields every year to achieve maximum production leading to deleterious environmental effects.The present investigation ‘Integrated nutrient management in cauliflower was undertaken at the Instructional Farm of Department of Horticulture, College of Agriculture, Latur during the Rabi season. The experiment laid out in Randomized Block Design (R.B.D.) with fourteen treatments replicated thrice. The treatment comprises with RDF (120:80:40 NPK kg/ha.), FYM (10 t/ha), Azotobacter and Azospirillum (10 kg/ha). The variety Snowball – 16 was selected for the study. The data regarding soil analysis after harvesting, the maximum available nitrogen (265.66 kg ha-1), available phosphorus (23.26 kg ha-1) and available potassium (415.33 kg ha-1) were recorded in highest dose of INM i.e. 100 % RDF + FYM + Azotobacter + Azospirillum(T2) and is was statistically at par with T6 and T8. The maximum organic carbon (0.93 per cent) was recorded in the treatment 75 % RDF + FYM + Azotobacter + Azospirillum(T6). There were no significant differences of INM treatments observed on soil pH and electrical conductivity. This result suggested that 25% chemical fertilizers can be reduced without any compromise on fertility status of the soil for cauliflower crop production in sub-tropical condition.

A field experiment was carried out at Research farm, Department of Horticulture, School of Agricultural Sciences and Rural Development, Nagaland University, Medziphema campus, Nagaland during 2018-2019 to evaluate the effect of integrated nutrient management on growth, yield, quality and economics of French bean (Phaseolus vulgaris L) under foothill condition of Nagaland. The experiment was laid out in randomized block design with eleven treatments and three replications. Results revealed that the application of different levels of fertilizes, organic manures and biofertilizers either alone or in combination significantly increased the growth, yield and quality of French bean as compared to control. Application of 50% NPK as inorganics + 50% vermicompost exhibited maximum plant height (34.3 cm), branches plant-1 (9.4), leaves plant-1 (27.3), pods plant-1 (26.3), length of pod (14.9 cm), width of pod (1.04 cm), seeds pod-1 (7.1), fresh weight of pod (7.1 g), pod yield (246.99 q ha-1) and crude protein content (28.8%). There was a significant build up of organic carbon and available nutrients except available nitrogen in post harvest soil with INM practices and maximum values of organic carbon (16.8g kg-1), available P (26.8 kg ha-1) and available K (126.8 kg ha-1) were recorded with 50% NPK as inorganics + 50% vermicompost. While maximum value of available nitrogen (297.6 kg ha-1) in post harvest soil was recorded with 100% NPK as inorganics. The highest net return of Rs 3, 45,388 ha-1along with cost benefit ratio of 3.04 was recorded in the treatment having50% NPK as inorganics + 50% FYM.

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.

The spatial variability of cellulase, amylase, protease and pectinase activities were evaluated from four zones of West Bengal, India. The enzyme production data was plotted on the map of the study areas and spatial variability of cellulase, amylase, protease and pectinase activity was obtained. Available nitrogen of the soil was the most variable parameter with changing enzyme activity. It also varied with the available phosphorus but the variation was least with organic carbon content of the soil. Amylase was correlated with pectinase, available nitrogen and phosphorus. Cellulase was correlated with only available nitrogen; protease was correlated with pectinase and Pectinase was correlated with available nitrogen of the soil of the four sampling zone. Except protease activity, other enzymes were significantly correlated with bacterial density of the soil. These findings ultimately develop relationship among soil major nutrients and the map can be used for future enzyme bioprospecting in West Bengal, India.
