Yield Responses of Maize (Zea maysL.) and Successive Potato (Solanum tuberosumL.) Crops to Maize Stover co-compostedwith Calliandra CalothyrsusMeisn Green Manure

The present investigation aimed at evaluating the effect of Calliandra calothyrsus Meisn green manure on quality improvement maize (Zea mays L.) stover compost. To that end, two field experiments were installed with and a successive potato (Solanum tuberosum crop, which was specifically set up to investigate potential residual effects tested organo-mineral fertilizers. crop did not receive any fertilizer, either organic or mineral. experimental design randomized complete block three replicates. basic plot 1.6 m wide 3 long (4.8 m²). Treatments under evaluation were: T1=Control, T2=Maize co-composted mineral T3=Maize co-compost manure; T4=Farm manure+45-60-30; T5=Maize manure+45-60-30. Evaluated parameters grain yields, root biomass, above-ground Harvest Index, Root/Shoot ratio for L.). Potato yields categorized into small size ( 65 mm). Significant (p 0.05) fertilizer treatments could be noticed harvest index (HI=0.31-0.38) R/S (0.079-0.088). For significant < 0.001) only observed seed-oriented medium tubers (MST) yield. Overall, most relevant observation experiment is T4 T5 gave higher equivalent biomass yields. From there, we derive sound substitute farm manure. Additionally, highlighted T3 treatment, statistically T2. Consequently, advise compost-based fertilizers should evaluated beyond single seasonal in order fully catch their potentials.
