However, this is not a general practice on large pepper plantations because raising an additional crop makes demands of its own, in terms of nutrient input, pest management, and so forth. It is important to note that companion crops to pepper must best be raised in the prebearing stage of pepper, which at best can extend from 3 to 5 years (at the most). This is because, when fully grown, pepper canopy could completely shade the accompanying crop and the latter would hardly yield. An experiment at the Indian Institute of Spices Research (Sadanandan, 1994) reported that an accompanying crop of banana (cv.
1993). Most pepper growers adopt varying nitrogen-tophosphorus-to-potassium (N:P:K) ratios, while Pillai et al. (1979) suggest an optimum ratio of 5:5:10 for nitrogen, phosphorus, and potassium to obtain the maximum yield. As far as the secondary nutrients (calcium, magnesium, and sulfur) are concerned, the only published work refers to calcium indirectly, through the effect of liming. 4 Nutrient Deficiency Symptoms in Pepper Nutrient Deficiency Symptoms Cited by Nitrogen General chlorosis and stunted growth.
On average, 2 kg of dry pepper vine1 were obtained. Companion cropping with arecanut has also been tried. An arecanut– pepper combination gave 3832 kg ha1 of dry dehusked arecanut and 1418 kg ha1 of dry pepper (Nair and Gopalasundaram, 1993) from 1000 vines ha1. Companion cropping is common in Brazil as well, where an array of companion crops—such as rubber, cocoa, orange, lemon, and clove—are extensively tried. Though growing mixed companion crops in pepper gardens is a practice in many situations, it needs to be clearly understood that when inter-specific crops are grown in association, the biological implications could be diverse.
