The Chavimochic irrigation project is one of the leading projects in Peru. In this project, irrigation water is derived from the Santa river to irrigate the valleys of Chao, Viru, and Moche, including desert zones between valleys. In this study, we aimed to characterise the Hass avocado and asparagus farms in desert areas of the Chavimochic irrigation project. Social, economic and environmental information was collected through structured surveys of 12 asparagus and 17 avocado farms. Four groups of asparagus farms and three groups of avocado farms were identified based on principal component and cluster analyses. Profitability of the avocado crop was higher than that of the asparagus crop, and irrigation caused more significant variability in the crop yield of avocado than that of asparagus. From the social perspective, the income of farm personnel was related to the level of education, ...

The objective of this study was to determine the allelopathic effects of leaf extracts of the forest species guaba (Inga edulis) and cadaghi (Corymbia torrelliana) on coffee (Coffea arabica ‘Caturra Roja’) plants grown under nursery conditions in Chanchamayo, Peru. Different doses of fresh leaf extracts were applied to coffee plants using a completely randomized design, with four treatments for each forest species (T1 = 0‰, T2 = 10‰, T3 = 20‰, and T4 = 30‰) and 12 replicate plants per treatment. It was found that none of the foliar extracts had an allelopathic effect on coffee plants in terms of height, stem diameter, number of leaves and dry weight; however fresh weight was significantly altered following “cadaghi” treatment.

The effects of gamma radiation on the germination, survival, and morphological damage in characteristics of the M1 generation of coffee (Coffea arabica L. var. typica) plants was evaluated using seeds collected from Santa Teresa and Chaupimayo, Peru. Under net house, the percentage of germination was 68%, 35%, 10%, and 0% for the Santa Teresa seeds and 75%, 49%, 17% and 0% for the Chaupimayo seeds with irradiation treatments of 0, 50, 100 and 150 Gy, respectively, whereas under laboratory conditions, germination levels were between 70% and 94% across all treatments. The survival rate also decreased with increasing radiation levels, with values of 45%, 32%, 28%, and 10% in the laboratory and 29%, 9%, 6%, and 0% in the net house for the Santa Teresa seeds and 58%, 45%, 38%, and 8% in the laboratory and 42%, 15%, 7%, and 0% in the net house for the Chaupimayo seeds with irradiation treatmen...
