Article History Correspondence to Keywords Manuscript No. IJEP5 A field study on the effect of organic manures and biofertilizers was conducted on the farmer field during the years (2009-10) and (2010-11). Heem Sohna, Rakshita, Naveen+2000 and Sun Seed 7711 varieties of tomato and K. Sel, California Wonder, Indra and Dollar varieties of capsicum were taken for the present studies. Farm Yard Manure (FYM) at the rate of 30 tones per hectare and vermicompost (VC) at the rate of 6 tones per hectares treated with Tichoderma viridi at the rate of 500 gm/2 tones of manures were made at the time of field preparation and during different stages of growth. In conventional treatment recommended doses of fertilizers and FYM were applied. In chemical treatments only recommended fertilizer dosages were used. The spacing adopted in tomato was 60×30 cm and 45×30 cm in capsicum. The highest yield of 134.4 tones/hectare in case of tomato variety Rakshita and 65.0 tones/ hectare in capsicum variety Dollar were recorded in conventional system whereas the corresponding figures were slightly less in organic system of cultivation. However, the yields in both the crops were drastically reduced under chemical cultivation. The fruit quality attributes were marginally higher in organic system of cultivation and the crop longevity was also noted to be prolonged to the considerable extent. *
Effect of Bio-Fertilizers and Organic Manures on Growth, Yield and Fruit Quality of Fruit Crops
2020
The major problem that occurs in developing countries is poor plant growth and yield due to soil infertility. Now-a-days to increase the crop production the fertilizers or pesticides used by the farmers in excess, which usually contain high amounts of chemicals, results in poor health of soil. In agriculture, use of inorganic compounds in high quantities has an impact on the sustainability of crop production, which consequently increases cultivation cost and decreases the productivity. The use of inorganic/chemical fertilizers, especially urea to the farming land lead to soil health reduced. Our farming has switched nowa-days to old age activities such as conservation agriculture. Bio-fertilizer, in general, is organic in nature and involves living organisms that synthesize the nitrogen in the atmosphere or create an environment that is useful to plants in the land or medium (in which the species are kept). On the other hand, the cost of bio-fertilizers is low and it has no adverse ...

Combined application of manures and fertilizers played a pivotal role in the improvement in soil physico-chemical properties, macro and micronutrients distribution and their transformations under different cropping systems. Based on a cropping system, the different levels of manures and fertilizers were used to study improvement in physico-chemical properties of soil. The aim was to explore the appropriate application of organic manures and inorganic fertilizers for improved sustainable yields of a cropping system. Intensive cropping systems lead to N, P, K, Zn, Cu, Fe, and Mn deficiencies in surface and subsurface soil, which could be refreshed with combined application of manures and fertilizers. The application of manures and fertilizers controls the pH and electrical conductivity of soil. Moreover, manures and fertilizers showed improvement is soil physical conditions viz. bulk density, particle density, porosity, and water holding capacity etc. Manuring coupled with fertilization helped to great extent for macro and micronutrient transformations in the soil. Under these transformations, the soil solution and water soluble component (fractions/pools) of soil is enriched with macro and micronutrients. There was a consistent declining trend of DTPA-extractable Zn, Cu, Fe, and Mn in the sub-surface soil in comparison to the surface layer, which may be ascribed to increase in pH with increase in depth and decrease of organic matter with depth. Similarly, manures reduced the concentration of residual macro and micronutrients in soil. Recently, integrated nutrient management system (INMS) is gaining importance visa -vis maintaining the soil fertility with conjunctive use of chemical fertilizers plus organic manures.

A study was conducted at Organic Farming Research Centre of SKUAST -Jammu to find out the impact of organic manures on soil secondary and micro nutrients following two-year vegetable cropping pattern. Significant results were obtained in Iron with highest value 32.69 kg ha-1 observed in T8 in okra and 33.68 kg ha-1 in broccoli. No significant changes were observed in Exchangeable calcium and Magnesium, Total Nitrogen and in DTPA Copper, Zinc and Manganese in this two-year experiment, however it is possible that after a certain period of time change can be noticed in certain secondary and micro-nutrient availability.

Aims: Growing the organic strawberry fruit in tropical and subtropical region with the help of shade of banana plants. Place and Duration of Study: The experiment was conducted at Research Farm, Department of Horticulture, Sam Higginbottom University of Agriculture, Technology & Sciences, Allahabad in the year 2017 to 2018. Methodology: A field experiment was conducted with cv. sweet charley of strawberry. The observations were recorded on various vegetative growths, flowering and fruiting parameters. The mean data were subjected to the various statistical and biometrical analyses. Results: Results show that there were major difference among treatments T3 Vermicompost (5 tonnes/ha) + Poultry manures (5 tonnes/ha) in plant height on 120 DAP (20 cm), number of leaves on 120 DAP (12.13), plant spread at 120 DAP (25.50 cm), days taken to first flower (60 days), number of flower plant-1 (14.37), days taken to first fruit (72 days), number of fruit plant-1 (7.40) fruit set % (52.12%), thr...
The Use of Compost Obtained from Sewage Sludge, as Fertilizer in a Peach Orchard
Fruit Growing Research
The study was carried out in a peach orchard, `Cardinal` variety, on a sandy soil, within the Dăbuleni Research - Development Station for Plant Cultivation on Sandy Soil. The experimental plot was fertilized with different doses of compost, obtained from sludge resulting from the processing of domestic wastewater. Following fertilization, the soil analyzes showed an increase in nitrogen, phosphorus and potassium content, with higher values for fertilized variants with doses of 60 and 80 t/ha compost, compared to the control variant. Also, in the leaves the macroelements registered the highest values in the variant fertilized with 60t / ha sludge compost (3.53% nitrogen, 0.32% phosphorus, 1.69% potassium). The soil heavy metals content recorded higher values on the variants fertilized with sludge compost, but the recorded values did not exceed the maximum allowed limits by the layer. The rate of the photosynthesis, the perspiration, the stomatal conductance and the chlorophyll conten...

Background: Health of soil is important being an integral part of any production system. As agroforestry aims to maintain the sustainability in the system, therefore, soil status under any agroforestry system plays key role. This study was conducted at Department of Silviculture and Agroforestry, Dr. Y.S. Parmar University of Horticulture and Forestry, Nauni-Solan HP (India) under Morus based agroforestry system.Methods: The present investigation was carried out during 2016 from month of July to October for quantifying the effect of application of organic manures on soil physico-chemical properties under Morus based agroforestry system. Five soil samples from each experimental plot were collected separately and a single representative composite sample was drawn for each plot replicated three times. The analysis of soil was carried out with standard adopted procedures.Result: Findings of the study revealed that different organic manure combinations were having significant influence o...
