Pulses are an important protein source for vegetarian people across the world and they have a great potential to improve the human health, contribute to global food and nutritional security. Variety of pulses were grown in India with 25% of global production and 27% of global consumption. Though India is the largest pulses producer in the world, it imports around 3.5 million tons annually to meet the ever-increasing requirement. Less adoption of improved Agro techniques, low fertile soils and unpredictable environment conditions are major factor for low production of pulses. As a results of increasing population, the projected pulses requirement will be 32 million tons by 2030 which necessitate annual growth rate of 4.2%. With adoption of suitable agronomic strategies, the productivity has to be enhanced to meet the demand. This review work was done at Department of Agronomy, Agricultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore, Tamil Nadu, India. Collected review and research papers were screened from various data base like TNAU e library, ARCC journals, google scholar, research gate and scopus used to write this paper. This review article documented information gathered on importance of pulses, area, production and productivity of pulses. Nipping is important agronomic practices that removes the apical bud dominance and promotes the lateral growth which turn better maintenance of source and sink relationship and enhance the pulses yield. Influence of nipping on growth and yield of various pluses crops has been discussed here. [ABSTRACT FROM AUTHOR]

Lessons learnt from past experiences push for an alternate way of crop production. One such is conservation agriculture (CA), which can be seen as a new way forward for conserving resources and enhancing productivity to achieve goals of sustainable agriculture. In recent past, progressive and significant efforts are made to develop, refine and disseminate conservation-based agricultural technologies across globe. Tremendous efforts on zero-till practices and surface management with crop residues for crop production were reviewed. This work was done at Department of Agronomy, Agricultural College and Research Institute, Tamil Nadu Agricultural University, Madurai-625 104, Tamil Nadu, India. A systematic cum integrative review of research work done in different parts of World, particularly in India was comprehended. Literature search was done during 2020. About 200 review and research papers were screened from various databases like TNAU e-library, ARCC journals, google scholar, research gate and scopus and 84 papers were used. This review article comprehensively documents major principles of CA along with extent and spread of CA across the globe. It also highlights CA in Indian perspective. Various merits and demerits were also discussed with literature support. This review paper discusses rising concerns of conventional agriculture systems with regard to its adoption, positives and negatives of conservation agriculture in promoting conservation agriculture in tropics.

Declining per capita land, water and other resources triggered by changing climate and increasing population need resource conservation technologies (RCTs) for agricultural sustainability. This paper has presented findings from recent research on resource conservation technologies that have been attempted in different regions of India. The superiority of resource conservation technologies (RCTs) such as laser land leveling, zero tillage, bed planting, direct seeded rice, leaf colour chart, green seeker and crop diversification over conventional methods of cultivation practices is evaluated in terms of saving of energy, water and labour, increase in crop yield, water productivity, nutrient-use efficiency, net returns and making agriculture climate smart. Zero tillage with residue retention increase soil organic carbon sequestration, conserve soil moisture and lower soil temperature thus making agriculture climate smart. Direct seeded rice is solution for labour scarcity, excessive water and fuel use in transplanted rice. Use of leaf colour chart saves nitrogenous fertilizers. Laser land leveling and bed planting practices increase water productivity and crop yield over conventional practices. But the machinery required for adoption of RCTs are heavy and costly, so the study has suggested the use of machines on co-operative basis and also the wider scale testing of new technologies under diverse production systems.

Industrial revolution and fast deforestation in 20th century pushes the earth to face climate change. Climate change became one of the most important global environmental challenges of the 21st century. Besides other weather abnormalities it is potential threat to world food security as agriculture production is directly dependent on various weather parameters. Even a small alteration in climate, adversely affects agriculture by decreasing the production. Global temperatures have already increased by 0.70°C over the past century and prediction of more rise of temperature is there. Possible changes in temperature, precipitation and CO2 concentration are expected to significantly impact crop growth. India could experience a 40% decline in agricultural productivity by the 2080s. Various food grain crops are going to affect badly under the temperature rise situation. It has been projected that under the scenario of a 2.50°C to 4.90°C temperature rise, rice yields will drop by 32% to 40% and wheat yields by 41% to 52%. This paper summarized study related to climate change projections and its impact on production of various crops. [ABSTRACT FROM AUTHOR]

Agriculture plays a central role in the economic development of a country. The population of India is expected to reach 1.5 billion by 2050 with a current decadal growth rate of ~18%. The review paper is written to highlight the current and future challenges facing the agriculture sector in India. There are various challenges that affect the Indian economy such as food security, soil quality deterioration, water scarcity, lack of proper food storage structures, land degradation etc. Recent pandemic situation has affected the agricultural sectors, will lends to the major changes in the future, which needs to be discussed and planned to meet the future requirements.
