Abstract

A study was conducted during 2000 - 01 to 2002 - 03 to explore the possibility of growing winter crops (post-rainy), mainly legumes during dry season in lowland rice fallow of eastern India (Dhenkanal, Orissa) with shallow water table (0.58-1.43 m). Four crops, i e groundnut (Arachis hypogaea L.), chickpea (Cicer arietinum L.), blackgram (Vigna mungo L. Hepper) and greengram (Vigna radiata (L.) R. Wilczk) were grown in winter season with supplemental irrigation after harvesting rainy season rice-oryza sativa L. Water balance and radiation interception of these crops were computed. Study revealed that owing to shallow water table, winter crops received sufficient soil water through upward flux and 52.6, 50.1, (h) 49.2 and 46.3% of crop water uses were contributed through soil water upward flux in groundnut, chickpea, blackgram and greengram, respectively without irrigating these crops. In addition to soil upward flux and residual soil water of profile, lirrigation increased grain yield (mean of 2 years) by 26, 32, 28 and 31% in groundnut, chickpea blackgram and greengram, respectively compared to no irrigation. Higher water-use efficiency of 3.52, 1.77, 2.75 and 2.42 kg/ha/mm was recorded with 1 supplemental irrigation in groundnut, chickpea, blackgram and greengram, respectively. Higher intercepted photosynthetically active radiation was observed with 2 irrigated crops with the values being 82, 79, 74, 75% in groundnut, chickpea, greengram and blackgram, respectively. The study amply revealed the scope of growing post-rainy season crops (groundnut, blackgram, greengram) profitably in rainfed shallow lowland rice fallow with utilization of residual soil water and soil upward flux.
