The System of Assured Rice Production (SARP) in kharif (wet) season is a resource-conserving, climate-resilient and farmers’ friendly methodology involving scientific principles and simple practices toward producing healthy and robust seedlings, prolonging nursery duration if required, and shortening main field duration of transplanted rice. The basic principles include production of high potential and healthy seedlings using very low seeding density (15–20 g m−2), adequate addition of organic manure (1.0–2.0 kg m−2), and adopting an integrated nutrient management practice (macro and micronutrients both) in nursery; flexibility in seedling age for transplanting in main field, based on prevailing weather situation; reduced requirement of quality seeds; and significant reduction in nursery area. The seedlings, thus, raised can remain fit in SARP (Kharif) nursery for transplanting even up to the age of 60 days, displaying no yield penalty in the main field as compared to the conventional transplanting of rice (CTR). At least 15% yield advantages are common when seedlings are transplanted at normal seedling age. Early sowing, delayed transplanting and early harvesting of kharif rice would allow enough time for raising a green manuring crop and its incorporation in rice cultivation through SARP (Kharif), and timely sowing of succeeding rabi pulses and oilseeds, thereby benefiting soil health and ensuring sustainability of rice-based cropping system. SARP (Kharif) also suits better in adopting the common crop sequence of jute-rice in jute growing areas of West Bengal. SARP (Kharif) is a two-in-one methodology in one way of realizing higher productivity and another way of contingent cropping to combat unfavorable climatic situations. Thus, SARP (Kharif) provides huge prospects and opportunities to the farmers in assuring their kharif rice production with multiple benefits including higher yields and profit margins even under climatic adversities.
