Correlation studies of soil properties under STCR approach with yield of maize ( Zea mays L.) In an acid Alfisol

Abstract

The present investigation was carried out to study the comparative effectiveness of farm yard manure and vermicompost under prescription based fertilizer application in maize-wheat system in an acid Alfisol at experimental farm of Department of Soil Science, College of Agriculture, CSK HPKV, Palampur. There were nine treatments which were replicated thrice in a randomized block design. The treatments were control, soil test based, farmers’ practice, 100% NPK, target yield (non-IPNS), target yield with 2.5t and 5t FYM ha-1 target yield with 2.5t and 5t vermicompost ha-1. The target yield for maize and wheat was 40 q and 35 q ha-1, respectively. The soil of experimental farm was silty clay loam in texture, acidic in reaction (pH 5.1), medium in organic carbon (7.8 g kg-1) with 208, 26.8 and 214 kg ha-1 of available N, P and K, respectively. All the chemical properties were positively correlated with grain and straw yield of maize.
