This study evaluates the benefit of zero tillage over conventional tillage for cultivating field pea (Pisum sativum L.) varieties in rice fallow system (RFS) during winter season of 2023 at Hengbung, Manipur. The study is conducted to compare the productivity of the two varieties V1-Aman (IPF 5–19), V2-Prakash (IPFD 1–10) with tillage practices, W1-zero tillage and W2-conventional tillage. Soil analysis after harvest is recorded for studying the residual effect.
The experimental design adopted is split plot design where the field pea variety, V1 and V2 is assigned in subplots and the tillage practices, W1 and W2 is assigned in the mainplots. The study involves four treatments (T) which are T1@V1W1, T2@V1W2, T3@ V2W1 and T4@ V2W2 in 1hectare experimental farm at FGI, Hengbung in RFS replicated five times. The data for agronomic parameters were recorded and Soil chemical analysis for nitrogen (N), phosphorus (P) and potassium (K) were recorded to study the residual effect.
The recorded agronomic parameters and their residual effect on soil nutrient indicates that zero tillage demonstrated better performance over conventional tillage with both the varieties. There is significant difference between the two varieties and also the nutrient released in soil after harvest where V1 shows better performance in yield and nutrient release over V2 and within the same varieties the treatment T1 and T3 shows better performance. The overall findings suggest that zero tillage significantly enhances the crop output of field pea cultivation in RFS.
