(iii) Socio economic constraints:<br />
● Fragmented land holding and smaller holding size.<br />
● Unavailability <strong>of</strong> work force i.e. agricultural labourers delays agricultural operations<br />
● Tenant farming system has led to improper soil care in irrigated areas.<br />
● In canal-irrigated tract, major agricultural operations are carried out on contract basis. Contract<br />
labourers are in the process <strong>of</strong> dictating terms with land owners and do not agree to adopt some<br />
<strong>of</strong> the recommended package <strong>of</strong> practices like shallow erect planting, maintenance <strong>of</strong> desired<br />
plant population, proper manual weeding etc.<br />
16. Major contribution <strong>of</strong> the centre in terms <strong>of</strong> varieties/technologies developed:<br />
16.1 Crop Improvement (Plant Breeding)<br />
16.1.1 <strong>Rice</strong> varieties developed at <strong>Chiplima</strong>:<br />
The high yielding rice varieties Lalat and Meher developed at AICRIP, <strong>Chiplima</strong> are widely<br />
grown in Orissa in both Kharif and Rabi seasons. Lalat covers more than 60 percent <strong>of</strong> rice area <strong>of</strong><br />
Orissa in Rabi season. Recently two rice cultures have been released in the State <strong>of</strong> Orissa in the name<br />
<strong>of</strong> Pratikshya & Siddhanta.<br />

16.1.2 Promising <strong>Rice</strong> Cultures Developed at <strong>Chiplima</strong><br />
The rice culture ORS 232-6 has been identified by DRR, Hyderabad through co-ordinated trials<br />
for release in Orissa. Proposal will be submitted very soon to the S.V.R.C. for their release in Orissa.<br />
