Technology for Intercropping in Guava Orchard | Chapter 11 | Current Perspectives in Agriculture and Food Science Vol. 4

 Guava has a recorded history from about fifteenth century. It is an important marketing fruit crop mature in India. This chapter aims to climax the benefits of Intercropping in guava orchards. Intercropping in guava orchards boosts plantation productivity and product quality by enhancing the potency level of the orchard soil. Intercropping determines farmers accompanying additional income during the whole of the juvenile stage of the guava plants.

Determination of Metabolic Responses of Psidium guajava L. Trees Irrigated with Polluted Water| Chapter 1 |Innovations in Microbiology and Biotechnology Vol.4

 The major purpose of this research was to investigate the main effects of waste water from the El- Wafaeyya drain (polluted site) on some primary and secondary metabolites, nutritional and heavy metal levels, photosynthetic pigments, and seedy fruit quality. Irrigated Psidium guajava trees acquired much higher amounts of Fe, Mn, Zn, Cu, Pb, Co, and Cd than those irrigated with clean water. In contrast, total photosynthetic pigments in P. guajava leaves watered with contaminated water were significantly lower than in the control. Total protein and total carbohydrates were found in higher concentrations in the leaves of the control location. Proline, free amino acids, antioxidants, total phenolics, total flavonoids, and tannins were found in abundance in tree leaves treated with contaminated water. The opposite was true in the case of total alkaloids and saponins. When it comes to fruits, the negative effects were concentrated on the economic output and number of fruits rather than their weight and size. Irrigation with dirty water, on the other hand, resulted in lower levels of water, total proteins, total carbohydrates, and vitamin A and C, but higher levels of dietary fibres. The use of both qualitative and quantitative electrophoretic pattern analysis improves the reliability of the findings in terms of the numerous genotoxic consequences that these drugs can cause. The use of P. guajava fruits harvested from polluted places for human purposes must be avoided since they are harmful, dangerous, and risky.

Soil Fertility Nutrition and Size of the Fruit of Guava with Liquid Organic Fertilizers | Chapter 2 | Cutting-edge Research in Agricultural Sciences Vol.1

 In Calvillo, Aguascalientes, guava is produced more than 100 years ago. In order to improve soil

fertility, promote plant growth and improve fruit quality, during 2014-2016 the experiment was carried
out. The fruit manure was prepared, manure tea and compost tea, each applied to the soil, foliage and
soil and foliage plus a witness, each treatment was repeated 4 times and a completely randomized
design was used, the experimental unit was a two-year-old tree of The "China" variety. Applications
were made every eight days. Soil treatments caused significant differences (P < 0.05) in Da, MO and
N. The P increased with the treatments applied to the soil and foliar and the K, Ca and Mg, were
excessive. In the soil solution the TéCS increased by 3.5 mg/kg, N and Na at 16.45 mg/kg. In leaves
the Na increased by 57.4 mg/kg and in fruit the treatments TéEF, TéCFS and AFF increased their
size. It is concluded that liquid organic fertilizers are a good ecological alternative to improve soil
fertility and guava nutrition.
