Impact of using fertilizers and tillage management in oryza sativa-cicer arietinum cropping system

Abstract

With an intention to study the impact of the ferlizers, tillage management and irrigation techniques used for raising chickpea (Cicer arietinum L.) after the cultivation of rice (Oryza sativa L.), an on-field examination was conduction at the Experimental Farm, Annamalai University in 2018. Under the treatment criteria of 30:60:40 kg NPK/ha along with deep ploughing (23 cm deep) with spade and cumulative pan evaporation (CPE) of 60 mm, significant increase in growth and yield sttibutes of chickpea was observed compared to that of 20:40:40 kg NPK/ha with normal ploughing and CPE of 80 mm. The former treatment also resulted in the significant increase in the yield rate of chickpea and chickpea-equivalent in comparison to the later treatment process. The monetary returns also increased. On the other hand, the deep ploughing (23cm deep) with spade recorded a significant higher grain and straw production of chickpeas along with chickpea-equivalent yield and monetary profit in comparison to the normal ploughing technique. Different tillage and nutrients management techniques showed a great impact on varied physical properties. Moreover, an outstanding impact was reported during the rabi season in case of the preceding crop (rice) in the following year.
