Abstract

It is imperative that the world farmlands turn out to be the frontline for the battle to feed the projected 9 billion population globally. The deleterious effects of climate change on food security can be counteracting by broad-based agriculture development particularly enhanced crop diversification to mitigate farmer risk about complete destruction of crop that will overcome the impacts of climate change. It will also lead to benefits like improved food security besides improving soil nutrients. Therefore, a field trial was conducted. The experimental results revealed that application of 100% NPK with PSB and Zn in paired planted mashbean accumulated significantly more dry matter than rest of the treatment combinations, whereas normal planted mashbean intercropped with maize recorded maximum total uptake (8.15%) than 100% NPK alone. Likewise in maize similar trends were observed in dry matter and protein content. Moreover, application of 100% NPK alone with PSB and Zn on normal planted sole maize was brought significant improvement in organic carbon and potassium. However, nitrogen recorded higher under paired planted maize+mashbean. Though, normal (50 cm) planted maize+mashbean resulted significantly higher B:C ratio (2.73) at same fertility level.
