Response of Chemical Fertilisation on Six-year-old Oil Palm Production in Shambillo-Padre Abad- Ucayali
Published on: 13th September, 2024
It was proposed to determine the response of chemical fertilization in the production of oil palm (Elaeis guineensis Jacq.) six years old in the area of Rio Negro Shambillo Padre Abad in order to have a sustainable and economic alternative of chemical fertilization in the field stage, which contributes to the survival of the palm and provides the necessary resistance against pests and diseases. A completely randomized block design (DBCA) was used with four repetitions and treatments, 96 plants / UE / treatment were used, the spacing was 9x9 in rows and plants. Results obtained indicate the treatments; T3 and T2 (16,54 – 15,48 kg / plant) obtained the highest averages by bunch weight, T1 and T3 (17,48 – 15,42 fruits / bunch) obtained the highest averages regarding number of fruit / bunch, T1 and T3 (13,93 – 11,59 to 45 cm ) obtained the highest averages for bunch length, T1 and T3 (7,33 – 5,52 cm) obtained the highest averages regarding fruit length, T1 and T3 (11.37 – 9.54 g) obtained the highest averages regarding fruit weight, T1 and T3 (10,46 – 10,37 kg) obtained the highest averages to yield per plant. The addition of chemical fertilizers or organic amendments increases the weight of the oil palm bunch, consequently the production in soils with medium, low fertility; chemical fertilization influences the number of clusters of oil palm produced on a given surface, any dose is used as an alternative to phosphorous fertilization in oil palm with a direct relationship between plant height and root length.
Forecasting Soil Moisture in Caragana Shrubland Using Wavelet Analysis and NARX Neural Network
Published on: 7th October, 2024
It is important for sustainable use of soil water resource and high-quality development to forecast the soil moisture in forestland of water-limited regions. There are some soil water models. However, there is not the best model to forecast the change of soil moisture in the caragana shrubland. In this paper, the plant water relationship has been investigated at the same time for a long term in the caragana shrubland of semiarid region of the Loess Plateau of China. The data of soil moisture was divided and then NARX neural network was used to build model I and model II. For model I, low frequency component was the input variable, and for model II, low frequency component and high frequency component were predicted. The results showed the average relative error for model I is 3.5% and for model II is 0.3%. The average relative error of predicted soil moisture in 100 cm layer using model II is 0.8%, then soil water content in the 40 cm and 200 cm soil depth is selected and the forecast errors are 4.9% and 0.4%. The results showed that using model II to predict soil water is well Predicting soil water using model II will be important for sustainable use of soil water resource and high-quality development.
Agriculture High-Quality Development and Nutrition
Published on: 24th October, 2024
Modern Agricultural production wants to efficiently produce plant products and benefits to meet people's needs. However, because of better plant species and varieties, overuse of fertilizer and overdose of pesticide alters the plant resources relationship, resulting in soil degradation, vegetation decline, and crop failure or waste of resources, which influence the quality of fruit and benefit and are unfavorable for the sustainable utilization of nature resources and crops high-quality development. After a couple of years of study, the results showed that Agricultural development went into agricultural high-quality development in 2017, which is to use effective measures or methods to maximize yield and benefits and meet the need of people's need for better Agricultural produce and a better life. The theory foundation of the sustainable utilization of natural resources and Agriculture high-quality production is the resources use limit by plants, vegetation carrying capacity, and critical period of plant resources relationship regulation. The methods of Agriculture high-quality development are to select excellent plant species or varieties based on site conditions and market needs before planting crop young plants and sowing seeds, adopt appropriate initial planting density when planting crop young plants and sowing seeds, and regulate the relationship between plant growth and resources need in the process of crop production in a timely and appropriate amount, especially the chemical fertilizer and pesticide to obtain the maximum yield and benefits and realize the sustainable utilization of natural resources and achieve agricultural high-quality development.
Inventorization and Exploration of Floral Diversity in Metropolitan Cities of India for Their Suitability in Floriculture of Kashmir
Published on: 18th November, 2024
Floriculture is the branch of horticulture that deals with the cultivation and management of flowers and ornamental plants and has blossomed into commercial activity with considerable growth and a useful crop diversification option, particularly for small farmers over the past three decades. It is a global industry with significant economic, social, and aesthetic values. Globally 171 countries practice floriculture. India occupies 51st position in terms of exports and contributes Rs. 455 crores which is 0.06% of global trade.The present study was carried out during the College on Wheels project organized by the Higher Education Council, Union Territory of Jammu & Kashmir, and was aimed to explore the floral and ornamental plant diversity of major metropolitan cities like Delhi, Goa, Bengaluru, Mumbai, etc. of India for evaluating their suitability for introduction in floriculture of Union Territory of Jammu & Kashmir.The floral and ornamental plant species were explored, photographed, evaluated, identified, and inventorised. A total of 51 species belonging to 23 different families of floral and ornamental plants were explored and evaluated in terms of parameters like climate, soil type, photoperiod requirements, watering needs, and maintenance requirements for their cultivation. It was found that some of the explored species of ornamental plants were already introduced into the Union Territory of Jammu and Kashmir because the parameters for the successful growth and thriving of these species match with the existing climatic and other conditions in the Union Territory of Jammu and Kashmir. Besides, the climatic and other requirements of some of the explored species were found in conformity with the climatic and other parameters available in the Union Territory of J&K for the successful establishment and growth of plants. Thus, there is an urgent need to introduce these explored species into the region to enhance the floral diversity of ornamental plants, beautify the landscape, and promote tourism and the generation of better livelihood. The Department of Floriculture should take a lead role in this direction to import these floral and ornamental plant specimens from pan India.
Plant growth, Yield and Leaf Nutritional value of Jute (Corchorus olitorius L.) as Influenced by Banana Peel levels under Salt Stress conditions in Coastal region of Cameroon
Published on: 30th November, 2024
In the world, millions of hectares of cultivated land are affected by salt, making salinity a major constraint for plant production. The effects of different levels of banana peel on growth, yield, and chemical changes of jute (Corchorus olitorius L.) under salt stress were examined herein. Response of jute to applications of different levels of banana peel (5, 10, and 15 t ha-1), as well as water irrigation salinity at 50, 100, and 200 mM NaCl were evaluated under greenhouse conditions. The outcome uncovered that salinity caused significant reduction of plant growth and yield parameters, chlorophyll (at 21.6%), LRWC (at 18.9%), P (at 57.1%) and K (at 45.4%) content, while MDA content (at 351.8%), Na (at 266%), soluble proteins (70.2%), total phenolic (at 23.4%) accumulation showed an increase from 0 to 200 mM NaCl without BP application. The banana peel treatments (at 15 t ha-1 under 200 mM NaCl) diminished significantly damaging effects caused by salinity via a reduction in the Na (at 28.4%), total soluble sugars (at 17.8%), total flavonoids (at 20.1%), which enhanced number of leaves per plant (37.1%), plant height (at 19.8%), leave yield (at 41.4%), LRWC (at 12.8%), Mg (at 24.2%) and reduced the MDA content (at 20%), presenting a favorable effect in reducing the oxidative stress that emerged from salt stress. It could be concluded, that the application of 15 t ha-1 of BP was superior in promoting plant growth, yield, and nutritional quality than others under control and in the saline soils in this study. BP at 15 t ha-1 had a more reduced damage of salt stress effect on growth, yield, nutritional value, and use efficiency.
