Cacao Yield Maximizing yield for farmers has become the main objective in business agriculture and because of this there has been a frequent reoccurring theme of large-scale plantations being less efficient in terms of yield than small-scale farms. Specifically‚ the smaller cacao yield in the large plantation is due to biodiversity‚ natural habitats‚ and most importantly‚ community ecology. The cacao plant’s productivity is heavily dependent on their age‚ planting density‚ plant variety‚ soil

Bacteria are unicellular and ultra-microscopic organisms‚ yet they play an important role in nature. They are of tremendous importance to man. They play an important role in agriculture and medicine and are the basis of many industries. Some are beneficial to man directly or indirectly‚ others are very harmful as they cause various plant and animal diseases. Bacteria are considered as our friends and foes due to their beneficial and harmful activities. Their economic importance can be studied under

Genetically Modified Organisms and the Hungry World For hundreds of years‚ humans have selectively bred and crossbred animals and plants to create or eliminate specific characteristics to produce a wider range of crops‚ animals and livestock. Genetic technology has become very common in our world today. Therefore‚ the possibility of altering plants and specifically crops for food supply raises many ethical and possible health issues which need to be explored. For example‚ the technical aspects

Quercus agrifolia also known as Coast live oak comes from the family of Fagaceae. Comprised largely of non-native trees like the ficus‚ magnolia‚ eucalyptus‚ and the iconic palm.Before the first human set foot here: the sycamore‚ the California bay laurel‚ the walnut‚ the oak. Of these‚ the oak tree especially has been a powerful force in shaping the region’s human history.

Pichia-produced chitinase It showed properties that are similar to the original chitinase E purified from the yam tuber‚ as reported by Arakane et al. (2000). This Pichia-produced chitinase showed also strong lytic activity against Fusarium oxysporum and Phytophthora nicotianae‚ wide pH and thermal stability‚ optimum activity at higher temperature such as 70oC‚ and high substrate affinity‚ thus indicating that we one can use this Pichia-produced yam chitinase as a bio-control agent.
