| Cow dung | Humic compounds and fertilizing bioelements are present in it and promotes the growth. Odour acts as a repellent for the insect vector. |
| Neem cake | Contains macro and micro nutrients. Sulphur compound in neem cake has negative effect on insects. All the components in it are needed for the plant growth. |
| Biocontrol agent (Pseudomonas fluorescens/ Bacillus subtilis) | It has a biopesticide property against seed and soil borne diseases and also produces metabolites related to growth promoting and preventing disease. |
| Macro nutrients | Improves plant growth, development, induce some enzymes involved in disease resistance mechanisms. |
| Micronutrients | Deficiency symptoms disappear and the plant develop normal leaves with high level of chlorophyll and involves in plant growth and development |

YRCH 1 |
2009 | 1861 kg/ha under rainfed 3000 kg / ha Irrigated | 150 – 160 days | 49 | Resistant to Green leaf hopper tolerant to wilt
|
Tamil Nadu |
Resistant to lodging, non-shattering type, highly fertilizer responsive with semi dwarf plant ideotype. Suitable for rainfed and areas of limited irrigation potential. The plant type is compact and relatively short in stature and augurs well for intercropping system also in addition to pure cropping system. Another more important special attribute is that the time lag between any two different order of spike is less when compared to GCH 4. Hence it produces more number of spikes per unit time and finally the total duration is also less with the duration of 150-160 days.
