Abstract

Continuous cropping (CC) obstacle is a major threat in legume crops production; however, the underlying mechanisms concerning the roles allelochemicals play in CC obstacle are poorly understood. The current 2-year study was conducted to investigate the effects of different kinds and concentrations of allelochemicals, p-hydroxybenzoic acid (H), cinnamic acid (C), phthalic acid (P), and their mixtures (M) on peanut root growth and productivity in response to CC obstacle. Treatment with H, C, P, and M significantly decreased the plant height, dry weight of the leaves and stems, number of branches, and length of the lateral

Abstract The aim of this study was to assess the land equivalent ratio, biomass, grain yield and ethereal extract of Helianthus annuus in monoculture and associated with Pisum sativum in function of stabilized urea (0, 40, 80 kg N/ha) in El Cerrillo, México. It was also estimated pod yield obtained by P. sativum as a pure stand and associated with H. annuus. The six treatments (in each experiment) were evaluated in a 2 × 3 factorial experiment in a randomized complete block design with four replications. When F values were significant, the honestly significant difference test at the 5%… More >
