Research Field

Performance of rice under integrated nutrient management in southern region of Tamil Nadu

Journal of Pharmacognosy and Phytochemistry (2019)

Field experiments were conducted at Agricultural Research Station, Thirupathisaram during rabi season of 2011-12 to study the effect of integrated nutrient management (INM) on rice under rice-rice-pulse cropping system. The treatments structure comprised viz., T1- Control (No manures/fertilizers), T2- Organic manuring (Sesbania aculeata @ 6.25 t ha-1), T3- Inorganic Fertilization (NPK @ 150:50:50 kg ha-1 for medium duration rice) and T4-Integrated Nutrient Management (Sesbania aculeata @ 6.25 t ha-1 + NPK @ 150:50:50 kg ha-1). Biometrics such as plant height, number of tillers hill-1, number of panicles m-2, number of grains panicle-1, panicle length, grain yield and straw yield were recorded. Integrated Nutrient management significantly influenced the growth and yield. The results revealed that treatment receiving application of Sesbania aculeata @ 6.25 t ha-1 + 150:50:50 kg NPK ha-1 for medium duration rice TPS 3 recorded relatively higher growth, yield and economics than other treatments.

Paclobutrazol treatment as a potential strategy for higher seed and oil yield in field-grown camelina sativa L. Crantz

BMC Research Notes (2012)

Sumit Kumar Sreenivas Ghatty J. Satyanarayana Anirban Guha BSK Chaitanya

Camelina (Camelina sativa L. Crantz) is a non-food oilseed crop which holds promise as an alternative biofuel energy resource. Its ability to grow in a variety of climatic and soil conditions and minimal requirements of agronomical inputs than other oilseed crops makes it economically viable for advanced biofuel production. We designed a study to investigate the effect of paclobutrazol [2RS, 3RS)-1-(4-Chlorophenyl)-4,4-dimethyl-2-(1H-1,2,4-triazol-1-yl)pentan-3-ol] (PBZ), a popular plant growth regulator, on the seed and oil yield of Camelina sativa (cv. Celine). A field-based micro-trial setup was established in a randomized block design and the study was performed twice within a span of five months (October 2010 to February 2011) and five different PBZ treatments (Control: T0; 25 mg l-1: T1; 50 mg l-1: T2; 75 mg l-1: T3; 100 mg l-1: T4; 125 mg l-1: T5) were applied (soil application) at the time of initiation of flowering. PBZ at 100 mg l-1 concentration (T4) resulted in highest seed and oil yield by 80% and 15%, respectively. The seed yield increment was mainly due to enhanced number of siliques per plant when compared to control. The PBZ - treated plants displayed better photosynthetic leaf gas exchange characteristics, higher chlorophyll contents and possessed dark green leaves which were photosynthetically active for a longer period and facilitated higher photoassimilation. We report for the first time that application of optimized PBZ dose can be a potential strategy to achieve higher seed and oil yield from Camelina sativa that holds great promise as a biofuel crop in future.
