Agronomic Performance Of Two Baby Lettuce Varieties (Lactuca Sativa L.) At Three Planting Densities Using Panqar Huyus In The Ingavi Province, Francisco Javier Orruel Fusco

Theses and Dissertations

This study was conducted in the experimental unit of the Benson Agriculture and Food Institute, which is located in the Letanias community of the Ingavi province in the department of La Paz. Our objective was to compare the agronomic performance of two baby lettuce varieties (Lactuca sativa L.) at three planting densities in panqar huyus. In order to provide the rural farmer communities of Contorno Letanias and Contorno Medio a possible cost-effective alternative and to employ the use of moderate environments called panqar huyus, we introduced two varieties of baby lettuce: 1) Little Gem in seed form and 2) Tom …


Evaluation Of The Use Of Climatically Controlled Pankar-Huyus Modules For Cultivating Lettuce, Lucio Guillermo Rocabado Paco Jan 2004

Evaluation Of The Use Of Climatically Controlled Pankar-Huyus Modules For Cultivating Lettuce, Lucio Guillermo Rocabado Paco

Theses and Dissertations

Pankar-huyus are becoming an alternative solution to the Bolivian Altiplano's climate problems for agriculture and to help provide adequate nutrition for the inhabitants of this region. Pankar-huyus are small modules with mild ambient temperatures that cover roughly 4 m^2. They are built underground and are covered by agrofilm caps that, in this study, were partially opened by day and closed at night. This study evaluated the climactic parameters of minimum and maximum temperature, minimum and maximum relatively humidity inside the pankar-huyus, wind velocity outside and inside the pankar-huyus at 40 cm from the soil and at the level of the …
