Field experiments were conducted at AICRP for Dryland Agriculture, Orissa University of Agriculture & Technology, Phulbani, Odisha (India) to study the yield performance of 10 important turmeric genotypes, and the effect of five different nutrient management practices on four outstanding varieties in order to address the problem of low rhizome yield and curcumin content of the zone. Based on yield data of 10 turmeric varieties over two years (2007 and 2008) evaluated in RBD with three replications, highest rhizome yield of 21.7 t/ha was observed in Lakdong followed by Rajendra Sonia (16.0 t/ha). The second experiment was laid out in factorial design involving four varieties and five nutrient treatments with 3 replications. The yield data over five years (2009-10 to 2012-13 and 2014-15) shows Lakdong (9.14 t/ha) to be the best among varieties and lime @10% LR + 50% organic + 50% inorganic (9.15 t/ha) among nutrient treatments. Significant variety × nutrient interaction was observed with respect to rhizome yield. Highest rhizome yield was obtained from turmeric variety Lakdong with 100% organic treatment (11.1 t/ha). While two varieties, Lakdong and Phulbani Local exhibited highest yield with 100% organic treatment, performance of Rajendra Sonia was the best with 50% organic + 50% inorganic + lime @10% LR and Roma with 50% organic + 50% inorganic. Significant variation was observed among nutrient treatments of all four turmeric varieties for NPK content in shoot and rhizome. The interaction between varieties and nutrient management practices for curcumin content was significant.

Climatic Scenario

<p>Agriculture is a complex network of interactions of plants with microorganisms. There is a growing demand for ecologically compatible environment friendly technique in agriculture that might be able to provide adequate supply of nutrients for the increasing human populations through improvement of the quality and quantity of agricultural products. Under the changing climatic scenario of global fluxes of the key biogenic greenhouse gases (CO<sub>2</sub>, methane and nitrous oxide), and some other environmental problems, the application of beneficial microorganisms in agriculture would serve as an important alternative gateway to some of the traditional agricultural techniques. Microorganisms of agricultural importance represent key ecological strategy for integrated management practices like nutrient management, disease and pest management in order to reduce the use of chemicals in agriculture as well to improve cultivar performance. The present review is intended to focus on the emergence of agriculturally important microorganisms (AIMs) to develop an ideal agricultural system through efficient utilization of nutrients and recycling of energy and thereby to preserve the natural ecosystem resources under climate change. The progress to date in using the beneficial microflora in a variety of applications related to agriculture along with key mechanism of action is also discussed in this review.</p>

Sugarcane is one of the lead crops in North Coastal Andhra Pradesh. Farmers in North Coastal Zone are opting for raising more number of ratoons owing to its substantially low cost of production. Ratoon crops however seldom receive proper care and inputs due to considered it as a bonus crop by majority of farmers. Field experiments were conducted consecutively for six years in the same field (2012-13 to 2018-19) at RARS, Anakapalle to study the monocropping effect on soil biology under the influence of different nutrient management practices. Irrespective of the year of ratooning, plots which received 50% recommended dose of chemical fertilizers + 25% nitrogen though vermicompost + 25% nitrogen through green manure incorporation resulted in higher microbial population over chemical fertilizers alone. Activity of dehydrogenase and active carbon pool also showed similar trend in multi-ratooning system of sugarcane. Rhizosphere microbial population at different growth stages revealed that, azospirillum population was observed highest followed by azotobacter while lowest population counts of phosphorus solubilizing bacteria were observed. Highest population counts were recorded in INM plots and population was highest at formative later reduced to harvest. INM with 50% RDFN + 50% through organics (66.80 t ha-1) recorded at par yields with 100% RDF (67.28 t ha-1).

Background: The significance of stabilized use of fertilizers is more populous between the farmers to get higher quality of produce. In integrative agricultural system, integrated nutrient management (INM) provide best way to solve numerous issues regarding sustainability, improving quality, boosting yield and keeping good soil fertility in efficient and economical way. Cabbage is one of the most valued crop among cole group vegetables and it is rich in vitamins and minerals like vitamin A, vitamin C, vitamin B1, B2 and B3, sulphur, phosphorus, calcium, magnesium, iron, potassium, sodium etc. Methods: Field experiments were conducted to study the effect of vermicompost, inorganic fertilizers and growth retardant (cycocel) with different spacing in cabbage and carried out in factorial randomized block design at Experimental Farm Bundelkhand University, Jhansi (U.P.) during rabi season 2017-18 and 2018-19. Fertilizers with cycocel treatment increases the accumulation of various minerals and vitamins. Result: Result indicated that quality attributes of cabbage were found to be highest and significant in the treatment where 50% RDF (Inorganic Fertilizer) + 50% Organic (vermicompost) were applied at wider crop geometry (45cm x 45cm spacing) along with spraying of 300 ppm cycocel (growth retardant). Head yield of cabbage was positively correlated with various quality attributes. Application of vermicompost along with inorganic in head of the cabbage. The experimental findings indicated that reduction in the amount of inorganic fertilizer was not detrimental to quality of cabbage while applying the vermicompost in proper amount that is 50% in combination with inorganic fertilizers. It is evident that integration of vermicompost and inorganic fertilizer at wider spacing under cycocel treatment enhances the quality of cabbage and also sustaining the fertility of soil.

The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, Bangladesh to investigate the influence of plant nutrient management on the yield performance of transplant Aman rice. The experiment comprised two Aman rice varieties viz. Binadhan-15 and Binadhan-16, and ten nutrient management viz. Recommended dose of inorganic fertilizer (RDF) Urea-TSP-MoP-Gypsum-ZnSO4 @ 150-110-70-60-5 kg ha-1, Cowdung @ 10 t ha-1, Poultry manure @ 5 t ha-1, Vermicompost @ 3 t ha-1 , 25% less than RDF + cowdung @ 5 t ha-1, 50% less than RDF + cowdung @ 10 t ha-1 , 25% less than RDF + poultry manure @ 2.5 t ha-1, 50% less than RDF + poultry manure @ 5 t ha-1, 25% less than RDF + vermicompost @ 1.5 t ha-1, 50% less than RDF + vermicompost @ 3 t ha-1. The experiment was laid out in a randomized complete block design with three replications. Binadhan-15 produced taller plants (97.86 cm), effective tillers hill-1 (6.28), grains panicle-1 (101.73), higher grain (3.58 t ha-1) and straw (4.99 t ha-1) yields compared to Binadhan-16. In case of nutrient management, 50% less than RDF + poultry manure @ 5 t ha-1 produced taller plants (101.1 cm), effective tillers hill-1 (7.07), grains panicle-1 (105.1) and grain yield (4.08 t ha-1). The highest grain yield (4.25 t ha-1) was recorded in Binadhan-15 fertilized with 50% less than RDF + poultry manure @ 5 t ha-1 and the lowest grain yield (2.28 t ha-1) was obtained in Binadhan-16 fertilized with vermicompost @ 3 t ha-1. So, it can be concluded that transplant Aman rice cv. Binadhan-15 fertilized with 50% less than RDF + poultry manure @ 5 t ha-1 appears as the promising practice to obtain the highest grain yield.

The Impact

The experiment was conducted in a greenhouse during 2017 and 2018 growing seasons to evaluate the impact of the shading and various nutrition programs on mitigating heat stress, reducing the use of chemical minerals, improving the reproductive growth and yield of tomato plant. Split-plot within Randomized Complete Block Design (RCBD) with three replications was conducted in this study. Shading factor was allocated in the main plots and the nutrition programs distributed randomly in the subplots. Results indicate that shading resulted in the decrease of daytime temperature by 5.7˚C as an average for both seasons; thus a significant increasing was found in leaf contents of macro nutrients (Nitrogen, Phosphorous, and Potassium), and micro nutrients (Iron, Zinc and Boron), except the Iron content in 2018 growing season. Furthermore, shading improved significantly the reproductive growth and tomato yield. Among the plant nutrition programs, the integrated nutrient management (INM) including the application of organic substances, bio inoculum of AMF and 50% of the recommended dose of chemical fertilizers; lead to the enhancement of nutrients content, reproductive characteristics and plant yield. Generally, combination of both shading and INM showed positive effects on plants nutrient status and persisting balance on tomato flowering growth and fruits yield.

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.

Barnyardgrass, large crabgrass, and Texas panicum were evaluated in field experiments over 3 yr to measure their duration of interference and density on grain sorghum yield. When grain yield data were converted to a percentage of the weed-free control, linear regression predicted a 3.6% yield loss for each week of weed interference regardless of year or grass species. Grain sorghum grown in a narrow (61-cm) row spacing was affected little by full-season interference; however, in wide (91-cm) rows, interference increased as grass density increased. Data from the wide-row spacing were described by linear regression following conversion of grain yield to percentages and weed density to log10. A separate nonlinear model also was derived which could predict the effect of weed density on grain sorghum yield.
