Effect of biochar and plastic mulch on growth, yield, and yield attributing characteristics of spring maize (Zea mays L.)

Spring maize is an important crop to meet the growing demand for maize. Moisture stress yield limiting factor during dry spring period. Biochar and plastic mulch help in soil moisture conservation might contribute growth of A field experiment was conducted evaluate effects biochar application on growth, yield, attributing characteristics (Zea mays L.) a sandy loam at Rampur, Chitwan, Nepal 2018. The laid out split-plot design (SPD) with three replications. Main plots were allocated mulching (mulching, no mulching) while Subplot rates 0 t/ha, 5 15 25 t/ha. There twenty-four each plot size 4.8 × 1.5 m2. grounded passed through 1 mm sieve applied well-prepared two weeks before seed sowing. seeds sown 60 cm row plant distance. significant due both factors emergence, height, number leaves per plant, leaf area index, root length, matter content, stover attributes. But significantly influenced by their interactions. Significantly highest grain (2.58 t/ha) obtained from t/ha followed (2.06 least recorded control (1.19 t/ha). From result, it can be concluded that higher rate contributes
