| dc.description.abstract | An investigation was undertaken to study the seasonal underground water quality and water table fluctuations in Raibag and Chikodi taluks (Belgaum district) of Ghataprabha command. Further during rabi seasons of 1995-96 and 1996-97, field experiments were carriedout in a farmers field at Alaknur village (Raibag taluk) to study the various modes of conjunctive use of underground and canal waters on soil properties, growth and yield of wheat. The analysis of underground waters revealed a shift from high salt concentration in summer to lower levels in rainy season. Winter samples exhibiting intermediate properties. Majority of the samples regardless of season, belonged to C3S1 and C3S2 classes. Among the twelve irrigation treatments adopted, namely T1 to T5 (one to five canal irrigations followed by groundwater supplementation), T6 (canal water alone), T7 (groundwater alone) and T8 to T12 (cyclic modes of canal and groundwater usage). T7 exerted deleterious effects on soil physical properties besides increasing in soil pH and electrical conductivity and reduction in availability of primary nutrients, and their reduced uptake and reductions in various agronomic growth and yield parameters. On the contrary, T6 was the best of the treatments in respect of both soil properties and crop growth and yield. The treatments in receipt of four or five canal water irrigations followed by groundwater supplementation (T4 and T5) under direct mode and those with the use of these two waters at the ratios of 1;1 or 2:1 under cyclic pattern of conjunctive usage, however, were found to be statistically not differing from the best of the treatments (T6). With respect to germination on the other hand, initial irrigation with groundwater was found harmful. Thus, it is concluded from the investigations that the conjunctive pattern in the manner as said above can be adopted without much harmful effect on soil properties and yield of wheat during the periods of canal water shortages. | en_US |
