State Land Development Banks (SLDBs), also known as State Cooperative Agriculture and Rural Development Banks (SCARDBs) in some states, are specialized cooperative institutions providing long-term agricultural loans secured against mortgage of agricultural land. They operate through Primary Cooperative Agriculture and Rural Development Banks (PCARDBs) at district or taluka level. NABARD provides long-term refinance (through the Long-Term Irrigation Fund and other instruments) to SLDBs for on-lending to farmers. Key loan types include irrigation loans for borewell and surface irrigation systems, land development loans for leveling and bunding, horticulture loans for orchard establishment, and farm mechanization loans for tractors and implements.

Land Laws section covers Transfer of Property Act 1882 (especially mortgage provisions — simple mortgage, usufructuary mortgage, and equitable mortgage used for agricultural loans), Registration Act 1908 (for land mortgage deed registration), Revenue Laws including state land records (khata, patta, pahani), mutation procedures, and land measurement systems. SARFAESI Act 2002 applicability to cooperative banks for secured loan recovery, and Revenue Recovery Act procedures used by cooperative banks are also tested. State-specific land reform acts (like Tamil Nadu Land Reforms Act, Karnataka Land Reforms Act) that affect agricultural land ownership and mortgage-ability are important for regional SLDB exams.

NABARD established the Long-Term Irrigation Fund (LTIF) with a corpus of Rs. 40,000 crore to finance the uncompleted major and medium irrigation projects identified under the Pradhan Mantri Krishi Sinchayee Yojana (PMKSY). LTIF provides low-cost long-term funds that NABARD channels through state governments and state land development banks for irrigation infrastructure financing. SLDBs benefit from NABARD's concessional refinance rates, which enable them to offer below-market interest rates to farmer borrowers for irrigation investments. Understanding LTIF mechanics, PMKSY scheme structure, and NABARD's role in agricultural infrastructure financing is important for SLDB officer positions.

Agriculture section covers major crops grown in the state, irrigation methods and their economics (drip, sprinkler vs flood irrigation), soil science basics (soil testing, pH, fertility management), horticulture crop requirements and establishment costs (for loan appraisal), farm mechanization economics (tractor utilization, equipment cost-benefit analysis), animal husbandry practices for dairy and livestock loan appraisal, fishery systems for aquaculture loan evaluation, and post-harvest infrastructure (cold storage, food processing unit economics). Knowledge of state agricultural universities' crop cost estimates (A2+FL cost, C2 cost) used in loan sizing is practically important for officers doing agricultural loan appraisal.

Short-term cooperative credit through PACS-DCCB-SCB chain provides seasonal crop loans (6-18 months tenure) for current agricultural expenses like seeds, fertilizers, pesticides, and labor. These are working capital loans that are repaid after harvest. Long-term land development bank credit provides investment loans (5-25 year tenure) for creating permanent agricultural infrastructure: borewells (7-10 year loan), drip irrigation systems (5-7 year loan), tractors (5 year loan), orchards (7-12 year loan with moratorium), and farm buildings. The long tenure and larger loan sizes of SLDB loans require careful mortgage-based security and periodic loan utilization monitoring, which is the primary responsibility of SLDB probationary officers.
