Abstract

The present investigation was carried out to study the status of major micronutrients in soybean growing soils of Latur district during the year 2009-2010. For this purpose 140 representative soil samples were collected from seven tehsils (20 villages from each tehsil) of soybean growing soils of Latur district. From each village one surface (0-15 cm depth) soil sample was collected and subjected to laboratory for analyzing for some chemical properties and status of available micronutrients viz., Zn, Fe, Mn and Cu. The correlation co-efficient between chemical properties and available nutrients were worked out. The study revealed that the soils were neutral to alkaline in reaction, safe in limit of electrical conductivity low to high in content of organic carbon and non calcareous to calcareous in nature. The soil samples were deficient in available Zn, medium to sufficient in available Mn and sufficient in available Fe and Cu. The data showed that available Zn had significant negative relationship with pH (-0.249^∗) and CaCO₃ (-0.198^∗) and significant positive with EC (0.269^{∗∗}). Available Fe had significant and positive correlation with EC (0.281^{∗∗}) and O.C. (0.217^∗) and significant negative with CaC_O3 (-0.291^∗). Available Mn had negative and significant correlation with EC (-0.278^{∗∗}) while Cu had positive significant relation with EC (0.199^∗) and O.C. (0.310^{∗∗}).

Abstract

Effect of applying organic manures (vermicompost and neem cake) and inorganic fertilizers on nutrient uptake, yield and quality of okra was studied under field conditions at the Research Farm, Department of Horticulture, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during summer 2012-13. Highest nutrient uptake by okra, yield of okra (no. of fruits plant^-1, weigh fruit^-1, fruit yield plant^-1, fruit yield ha^-1) and quality attributing character i.e. high protein content and low crude fibre content of okra fruits was recorded in treatment receiving 100 per cent RDF over other treatments which was statistically at par with treatment 75 per cent RDF + 12.5 per cent RDN through vermicompost + 12.5 per cent RDN through neem cake followed by treatment 75 per cent RDF + 25 per cent RDN through vermicompost and 75 per cent RDF + 25 per cent RDN through neem cake.

Abstract

To study thze quality of irrigation water from Ahmedpur tehsil, the present investigation was carried out during the year 2010-2011. Total three hundred ground water samples were collected from 30 villages of Ahmedpur tehsil periodically in two season's i.e. summer season (May, 2010) and winter season (October, 2010). The ground water samples were analyzed for its composition and parameters like pH, EC, cations (Na⁺ and K⁺), anions (Cl^-, SO₄^- and boron). Soil samples were also collected from the same places of Ahmedpur tehsil, with a view to studying the changes in chemical properties of soil viz., pH and EC. The water samples were alkaline in nature with dominance of sodium and sulphates. Majority of the well waters were higher in salinity class, indicating moderate suitability for irrigation. Among the cations Na⁺ was dominant in water followed by K⁺. The relative proportion of anions were in the sequence of SO₄→Cl^-. The boron concentration of irrigation water ranged from 0.90 (winter) to 1.07 (summer) ppm which was moderately safe (C₂) for irrigation. Irrigating the soils with such water, average pH and EC of soils were changed accordingly in summer and winter season.

Abstract

The sunflower growing soils of eastern Vidarbha region have been investigated for assessing the agro environmental suitability. Six pedons from high intensity area of Bhiwapur and Umred of Nagpur district were selected for study. Crop yield data were collected during field survey and other physical and chemical properties were studied in the laboratory and yields were correlated with soil properties. The investigation revealed that high intensity sunflower growing soils belonged to Typic Haplusterts, alkaline in reaction (pH 8.2 to 8.7) and low to medium in organic carbon content (0.24 to 0.79 %) and high cation exchange capacity (47.91 to 58.71 %), calcium carbonate were < 5 per cent, Ca : Mg ratio varied from 1.8 to 2.6 indicating moderate drainability and base saturation (85 to 89 %). Among the DTPA- extractable micronutrients, zinc was low while the soils were medium to high in manganese and iron and low to high in copper content. The sunflower yield when correlated with agro edaphic parameters it was found that rainfall and major soil physical and chemical characteristics influenced the crop yield. The stepwise regression analysis of sunflower yield with agroenvironment properties reveal that Typic Haplusterts distributed over four villages of Bhiwapur and Umred tahsils of Nagpur district that pH, Ca, Na, sum of cations, CEC, ESP, Mn, sand, clay and water retention at 1500 kPa had positive correlation. The high correlation co-efficient obtained with water retention at 33 kPa (0.91), post Kharif rainfall (0.90), clay (0.87) and water retention at 1500 kPa (0.72) indicating yield influencing factors.
