 ABSTRACT

A survey work was conducted during kharif 2014 to assess the impact of dry-direct seeded rice (Dry- DSR) cultivation and puddle transplanted rice cultivation on soil physical, fertility status and crop productivity in selected farmers fields of agroclimatic zone 2 of northern Karnataka region covering the villages of Kasbe camp, Mamdapur, Vijaynagar camp (zone 2). Soil samples and crop yields data were collected from farmers fields having direct seeded rice system and puddle paddy fields. The results revealed that, the soil bulk density was low in Dry-DSR system, available water was more in Dry-DSR system and also soil porosity and maximum water holding capacity was more in Dry-DSR system. The soil fertility status was also showed an improved status in Dry-DSR system. The yields were comparatively on par with both the system but when compared with the cultivation systems TPR system was higher yield.

Key words: Direct seeded rice, transplanted puddle soil.
