Phenotypic Differentiation and Yield-Component of Farmer-Recognized Black Pepper ( Piper nigrum L.) Genotypes in Selected Tanzanian Agroecosystems
Black pepper ( Piper nigrum L.) is an economically important perennial spice crop in Tanzania, but the identity, phenotypic distinctness and yield-component characteristics of farmer-maintained planting materials remain poorly documented. This study characterized farmer-recognized black pepper genotypes using integ...
