A field experiment to assess the effect of organic fertilizers on the growth and yield of cabbage was conducted at the Research farm of Indian Institute of Vegetable Research, Varanasi (U.P.). A Randomized Block Design with four level of FYM replicated three times was used in the experiment. Neem seed kernel extract (NSKE) 4 per cent was sprayed at the advent of insect pest infestation. In addition to marketable yields, cabbage leaves were digested and analyzed for 11 macro- and micronutrients. Vitamins C and E of mature crops were evaluated by high performance liquid chromatography. Soil samples were also taken at harvest, extracted with suitable extractant solution and analyzed for essential nutrients. Application of different level of FYM had varying effects on the growth and yield of cabbage. Effect of FYM was better in both the cabbage variety with respect to their variables measured, i.e. height, marketable head weight, and yield per ha. These findings can be explained in terms of the availability, especially, of the macro-nutrients in each of the treated plots. The impact of irrigation frequency on yield is transparent. We conclude that irrigation frequency had a significant bearing on yield.Keywords

Coalfield mine overburden or abandoned mine sites is a major environmental concern. Overburden materials are nutrient-poor, loosely adhered particles of shale, stones, boulders and cobbles and are devoid of true soil character. Eco-restoration or natural transformation of overburden materials to soil for cultivation is a time taking process. In the present study, we focused on how the OB materials are different from nearby natural soil and explored the characterization of physical, chemical and biological properties of different aged overburden undergoing the process of eco-restoration. Further, we have analysed various microbial population, enzymatic activities and microbial respiration process in different aged overburdens vis-a-vis nearby soil. Microbial population was more in 16 year old overburden among different aged OB but less than nearby soil. Dehydrogenase, Urease activity showed an increasing trend with maturity age of overburden representing higher microbial population, while alkaline phosphatase activity is not following any trend. Soil microbial respiration was found to be increased with age of overburden. Carbon mineralization rate constant in all overburden lied in a narrow range (0.020-0.011) day-1 and it did not show any significant variation as compared to native forest soil (0.03 day-1). Mineralizable carbon was found more in native soil (7.95 mg C/kg of overburden) and 16 year old overburden (5.56 mg C/kg of overburden). Cumulative CO2 evolved was more in native forest soil (8.67 mg C/kg), and was comparable with 16 year old overburden (5.4 mg C/ kg). Microbial population, enzymatic activity and carbon mineralization can act as an indicator for analysing changes in overburden spoil properties due to ecorestoration.Keywords

A field experiment was conducted consecutively for three years in rice crop with phosphocompost in the research farm of Sheila Dhar Institute of Soil Science, Allahabad University, Allahabad. The laboratory analysis for determination of threshold limit of N and P in the Gangetic alluvial soil was carried out partly at Indian Institute of Vegetable Research, and Institute of Agricultural Sciences, Varanasi. A significantly enrichment of per cent organic C and total N, Ca, Mg, K, Fe, Mn, Zn and Cu content was recorded in compost when prepared with application of Missouri rock phosphate @ 1% of total substrate biomass. The enriched compost alone or in combination with inorganic fertilizers was found effective in terms of supplementing readily available phosphate ion in soil pool for rice crop. The soil P content in different crop growth stages, protein per cent in grain, N and P content in grain and straw, plant population/m2, number of panicle, panicle length (cm), number of grain/ panicle, 1000 seed weight and yield in rice crop was significantly different under the influence of phosphocompost. The level of available nutrients and nutrient balances in soil was also significantly higher when treated with phosphocompost in combination with inorganic fertilizer compared to alone application of either inorganic or organic forms of nutrients. The nutrient use efficiency, apparent recovery of nutrients, soil nutrient balance sheet and cost:benefit ratio were also found higher and in direct proportion to supplementation rate of inorganic fertilizers by phosphocompost. A significant correlation between protein content in grain, grain yield, N uptake and available P in soil pool was established.Keywords
