Yield Gaps and Constraints in kharif Groundnut Cultivation - A Case Study of Kolar District in Karnataka

摘要

A study was conducted in Kolar district with a view to identify the constraints in kharif groundnut cultivation. Primary data were collected from the sample farmers while the research and frontline demonstration data of AICRP on groundnut, Agricultural Research Station, Chintamani were utilised. The results revealed that there was sizeable total yield gap in groundnut. The magnitude of yield gap-II was higher than yield gap-I. The major constraints perceived by the farmers in attaining higher yield in groundnut were problems in seeds and fertilizers, erratic distribution of rainfall, non-availability of labour, marketing, weeding and intercultivation, plant protection, poor extension work etc. The possible suggestions offered by the respondents to overcome the constraints in kharif groundnut cultivation were also discussed.
