Title:

Effect of litter and leaf leachates of Dendrocalamus strictus on soybean and wheat crop under pot culture experimentation.

Authors:S. Nema and G. R. S. Reddy

Abstract:The pot culture study was conducted to assess the effect of early age bamboo leaf litter and leachates/ aqueous extract of Dendrocalamus strictus on two popular agricultural crops of the Central India region i.e. Glycine max Linn. (Soybean) and Triticum aestivum Linn. (Wheat) to understand the suitability of intercrop under bamboo based agroforestry system in degraded agricultural lands in Jabalpur (Madhya Pradesh) India. Different applications of leaf litter quantity and leaf leachates concentration of i.e. 0.0, 1.0, 2.5, 5.0 and 10.0 per cent concentrations of Dendrocalamus strictus were used to study the effect on germination, number of tillers/ number of pods, plant height, root biomass, shoot biomass, grain yield and total biomass of both soybean and wheat crops. The results on pot culture of soybean in combination with D. strictus in sum revealed that in lower concentration had given a positive response on measured parameters and inhibitive response in higher concentration. Similar trend was also found in case of Wheat grown in combination with D. strictus, revealed that germination was inhibited significantly, however, the other measured parameters have shown a promoting response in the lower concentration and inhibitive in higher concentration equivalent of 200 g litter plus 10.0 per cent concentrations of bamboo leaf leachates per pot. The pot culture bioassays study of litter and leachates of Dendrocalamus strictus indicates that the inhibitory effect was pronounced for higher litter and leaf leachates concentrations, whereas the lower litter and leaf leachates concentration addition showed stimulatory effect in some cases.
