Photosynthesis, crop health and dry matter partitioning are among the most important factors influencing crop productivity and quality. Identifying variation in these parameters may help discover the plausible causes for crop productivity differences under various management practices and cropping systems. Thus, a 2-year (2019-2020) study was under...

The sustainability of conventional rice (Oryza sativa L.) production systems is often questioned due to the over-mining of groundwater and environmental degradation. This has led to the development of cost-effective, resource-efficient, and environmentally clean rice production systems by optimizing water and nitrogen (N) use. Hence, a 2-year field...

Agroforestry is considered as sustainable agriculture system compared to conventional agriculture and forestry because it offers various environmental benefits through integrated natural resource management practices. This system provides numerous ecosystem services (ES) by bridging the gaps between agriculture, forestry, and animal husbandry. This...

Rice straw is a low-density crop residue. It is produced in huge quantities every year across the country. Therefore, the management of rice residue has become a problem for farmers. Farmers have to vacant the field as early as possible for sowing of the next crop. Hence, they go for the burning of crop residue and now it has become the common prac...

Drones are transforming the face of global agriculture by providing enormous opportunities for precise management of agricultural inputs such as fertilizers, agrochemicals and natural resources such as soil and water. The impact of drone technology for agricultural management comes from its ability to survey a large area in short-time and providing...
Article
Rice is a crop of primary importance in regions, where two-thirds of the world’s starving population reside. Recent climate change projections anticipate spatial shift in precipitation pattern and increase of flooding events that may have negative effects on rice yield and economic returns. Efforts for increasing rice production in areas prone to s...

Impacts of climate change (CC) and climate variability (CV) are felt throughout the world as it’s getting hotter. As a result, irregular distribution of precipitation, a progressive rise in the oceanic levels, and more frequent occurrence of extreme weather events (EWE) have become a common phenomenon in recent years. Extended episodes of drought,...
Technical Report
This is the Tamil version of the extension bulletin "Rice Stakeholders Advisory on COVID-19". ICAR - National Rice Research Institute, Cuttack has taken the initiative to develop a special advisory on COVID-19 to ensure safety of various rice stakeholders of the country. This special advisory has been developed by considering the different operatio...

A field experiment was conducted during the rainy season of 2015 on sandy-loam soil at ICAR-Indian Agricultural Research Institute, New Delhi, to study the effect of variable irrigation regimes and nitrogen rates on yieldcontributing parameters, yield and nutrient uptake in maize (Zea mays L.) hybrid ‘PEEHM 5’. Irrigating maize at 25% depletion of...

Indian Farming 67(03): 22-25; March 2017 In India, the efficiency of fertilizer use is quite low, for example less than 40% for nitrogen (N) in rice. Also due to increased application of NPK fertilizers to cereals and taking heavy harvests year after year, most Indian soils have shown symptoms of fatigue with respect to secondary and micro nutrient...
Article
The results of the study showed that irrigating maize at 25 and 75% DASM led to higher NPR, PAR interception, dry mass accumulation in different plant parts over rainfed crop. Among N-rates, the higher values of NPR and PAR interception were observed at 200-300 kg N/ha. Both PAR interception and NPR were positively correlated with grain yield, the...
