Abstract

The present investigation was carried out for identification of soil nutritional constraints and suggest land use planning of UPRS and CCBP farm of Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani. Total one sixty surface soil samples (eighty from each farm) were collected from UPRS and CCBP farms of Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani. These soil samples were analyzed for soil properties and fertility status of soil. The results revealed that the soils of UPRS (upland paddy research station) and CCBP (cattle cross breeding project) farms were moderately alkaline in soil reaction, within safe limit of electrical conductivity, low to moderately high in organic carbon content and calcareous in nature. According to concept of soil nutrient index by Ramamoorthy and Bajaj, soils are low in available N, S and Zn while medium in available P and high in available K, Ca, Mg, Fe, Mn and Cu. Further, the organic carbon content showed positive and significant correlation with soil available N, P, S as well as micronutrients like DTPA-Fe, Mn and Zn. For planning of land use, the soil site suitability characteristics of UPRS and CCBP farms showed that these soils were highly suitable for growing soybean, pigeonpea and moderately suitable for growing cotton crop. The nutritional constraints identified were the deficiencies of available N, S and Zn in UPRS and CCBP farms of Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani.

Keywords

Abstract

A field experiment was conducted at Dry land Research Station,Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani during 2003-04 and 2004-05 in Vertisol with application of organics and inorganics sources of nutrients under different cropping system viz., soybean-pigeonpea and sorghum-pigeonpea. The results revealed that, all nitrogen fractions like total hydrolysable nitrogen., amino acid nitrogen, organic ammonium nitrogen, acid insoluble nitrogen and total nitrogen were increased significantly in all treatment combinations. The combined application of organic and inorganic fertilizers caused significant increase in available nutrient status of soil. The relationship as simple and multiple regressions between available N and different N fractions was interdependent to each other.

Keywords

Abstract

Soil sample of 0-30 cm depths and leaf samples from the bud differentiation stage were collected from the 31 micropropagated banana orchards of Marathwada region of Maharashtra to study the micronutrient status. The analysis of soil revealed that the orchard soils were sufficient in DTPA extractable Zn, Cu, Fe and Mn and leaf analysis indicated deficient to sufficient in range. The pH had the negative correlation with available Fe and Mn and positively correlated with Zn, Cu, organic carbon positively correlated with Zn, Cu, Fe and Mn. The leaf micronutrient concentration non significantly correlated with soil micronutrient cation.

Keywords

DTPA Extractable Soil Micronutrient Cation, Leaf Micronutrient Concentration, Soil Properties, Micropropagated Banana.

Abstract

Soil sample of 0-30 cm depths and leaf samples from the bud differentiation stage were collected from the 37 sucker propagated banana orchards of Marathwada region of Maharashtra to study the micronutrient cation status. The analysis of soil revealed that the orchard soils were sufficient in DTPA extractable Zn, Cu, Fe and Mn and leaf analysis indicated deficient to sufficient in range. The pH had the negative correlation with available Fe and Mn and was positively correlated with Zn and Cu. Organic carbon was positively correlated with Zn, Cu, Fe and Mn. The leaf micronutrient concentration non significantly correlated with soil micronutrient cation.
