摘要

Field experiments were conducted to standardize in situ soil and moisture conservation measures in rainfed guava production. Mulching with polythene enhanced soil moisture (upto 111%) and the impact was much visible for longer periods (160 days) after cessation of rainfall. Further, higher soil organic carbon built up (from 0.68 to 0.92 % O.C. over a period of three years) was observed with polythene mulching. It was also reflected in the nitrogen content of the soil which increased from 109.4 to 354.8 kg/ha during three years period. Polythene mulching with raised soil around the root zone showed 39.8 % higher fruit yield in guava over control on three years pooled mean basis. The treatment recorded 12.30 t/ha at sixth year of guava planting. Mulching with polythene although recorded slightly lower gross returns (Rs.6,19,870/ha), recorded higher benefit cost ratio (1:5.25) and was followed by mulching with enriched coir pith (1: 4.83).
