Abstract: “Rice is Life”for millions of people and staple food for more than partial of the worlds‟population. The request for rice is growing with ever increasing population. Atpresent the grain yield in rice has to be increased and the yield achieved hasto be sustained.[3] The pitch studies at Wetlands, Tamil Nadu AgriculturalUniversity Coimbatore resulted in compilation of agronomical use of neem andits by products in rice cultivation. The Wetland Farm at Cultivated College andResearch Institute, Coimbatore is situated in the Western Agro Climatic Zone ofTamil Nadu at 11° North Latitude and 77°East Longitude at an altitude of 426.72m above MSL.[2] The properties of neem as insecticide, antifeedant, hormonal,antifungal, antiviral and nematicide properties is well known .These activitiesare brought out with neem use in the form of leaves, leaf extracts, seeds,cakes, oil and fruit extracts. The neem and its products are used in seed  treatment, manurial  application, increasingnutrient efficiency by which the grain yield in rice crop is enhanced and itssustainability is seen in rice based cropping system. Evaluation of theseproducts in managing the rice crop, through agronomial cultural practices atvarious stages of crop growth has been discussed in detail in this paper.[5]
