Field experiments were conducted to study the effect of establishment techniques on yield and economics of red gram [Cajanus cajan (L.)] under irrigated condition at Regional Research Station, Tamil Nadu Agricultural University, Paiyur - 635 112,Tamil Nadu, India during Kharif season of 2013-14 and 2014-15 respectively in randomized block design with four replications. The treatments are line sowing/dibbling of seeds, sowing behind the country plough, sowing in polybag and transplanting at 25 and 40 DAS, sowing in portrays and transplanting in 25 and 40 DAS. The redgram variety LRG 41 was used for study. The results revealed that, dibbling of seeds in lines recorded higher grain yield of 2351 kg ha-1, net income of Rs.99495/- and B:C ratio of 3.39. Thus, dibbling of seeds in lines recorded 6% higher over sowing in poly bag and transplanting at 25 DAS and 27% higher yield over sowing behind the country plough. Considering yield and economics, line sowing seems to better option for the farmers followed by sowing in polybags and transplanted in 25 DAS. Under transplanted situation, transplanting of seedlings at 30 DAS was more suitable where the monsoon was delayed for 30 to 45 days under rainfed situation.

Sustainable Sugarcane Initiative (SSI) under Sub Surface Drip Irrigation (SSDI) is gaining momentum among the farmers because of more output with less input. Even though the benefits of SSI under SSDI are realized by farmers, development of optimal irrigation and fertigation schedule is need of the hour for Western Agro-climatic zone of Tamil Nadu. Field trials were carried out at Agricultural Research Station, Bhavanisagar from 2014 to 2017 to develop an optimal irrigation and fertigation schedule for SSI for Western Agro-climatic zone. The experiment was taken in a randomized block design with three replications. The experiment consisted of eight treatments of which six treatments comprised of SSDI with three irrigation regimes of 100, 80 and 60 percent pan evaporation and two fertigation levels of 100 and 75 percent of recommended N & K and two treatments in surface drip irrigation (SDI) with 100 percent pan evaporation (PE) + 100 percent RD and 100 percent PE + 75 percent RD of N&K through fertigation. The results of this study revealed that SSDI with 60 per cent PE + 100 per cent RD of N&K through fertigation recorded lower water use (1004 mm) and higher WUE (113 kg/ha-mm). However, significantly higher and comparable yield of sugarcane (148 t/ha) was recorded in SSDI with 100 per cent PE + 100 per cent RD of N&K through fertigation and surface drip irrigation with 100 per cent PE + 100 per cent RD of N&K through fertigation. The net return (Rs. 2,09,405 per ha) and B:C ratio (2.6) was higher in SSDI with 100per cent PE + 100 per cent RD of N&K through fertigation treatment.

Field experiments were conducted at Coconut Research Station, Aliyarnagar during 2016 – 2019 to assess the performance of rice-based cropping sequences for water-scarce conditions of the Parambikulam Aliyar Project Command area of Tamil Nadu. Five cropping sequences viz., rice–sesame (T1), rice–groundnut (T2), rice– sunflower (T3), rice–castor (T4) and rice–black gram (T5) were experimented adopting Randomized Block Design with each sequence replicated four times. Results revealed that compared to the other non-legume sequences experimented, the contents of KMnO4-N and organic carbon in the post harvest soil, productivity of rice and economic efficiency were higher in rice–black gram followed by rice–groundnut sequence. Rice– castor sequence recorded the highest land utilization efficiency of 76.7 % and was the lowest in rice–black gram sequence (53.4 %). Rice equivalent yield was the highest on sequential cropping with sunflower (5755 kg ha-1) followed by groundnut (5028 kg ha-1). Production efficiency was the highest in rice– groundnut (47.5 kg ha-1 day-1) followed by rice–castor (42.5 kg ha-1 day- 1) systems. Net returns and benefit-cost ratio were higher in rice–sunflower and rice–black gram sequences followed by rice–groundnut and was the lowest in rice–sesame sequence. In terms of soil fertility, system productivity and economic returns, rice–sunflower, rice–black gram and rice–groundnut systems are highly remunerative for water-scarce conditions of Parambikulam Aliyar Command Area of Tamil Nadu.
