Discriminate function analysis in Indian bean (Lablab purpureus L.)

Abstract

The varying mode of different farmers’ cultivation techniques reformed the qualitative and quantitative attributes related to yield of two cultivars/genotypes (V1 and V2). In field factors, the treatment T7 (Zero Tillage, Mulching, Irrigated) showed upper value in most of the characters emphasizing the topmost effect by lowering the seed moisture content, an vital qualitative parameter at harvest. The prospect of T3 (Conventional Tillage, Higher NPK, Irrigated) was also noticeable in other cases like thousand seed weight that deal with decisive target, seed yield. In a few cases like weight of seed-pod ratio, plant population etc., T10, T5 and T6 individually showed topmost peak for specific character. Considering all field based yield linking parameters, the specific mulching effect showed a positive response for irrigated (T7) and rainfed situation (T10), though presence of fertilizer (T3) highlighted a positive role to fulfil the quantitative approach. The variation in variety continued the top effect on V1 only in incidence of maximum response of T3 where V2 frequently in occurrence of T7. The same trend was observed in interaction of that specific genotype-treatment combination of that specific character.
