 Pineapple Ananas comosus in family Bromeliaceaeis a large, succulent, and tasty fruit with immense health benefits. Among all the cultivation activities of pineapple, harvesting is the most difficult, time consuming, and energy intensive process due to the higher plant density and spiny leaves of pineapple plants. Although, mechanization helps to increase the efficiency and post harvest quality, very little attention has been drawn to the mechanization of the harvesting process. Therefore, the aim of this study was to introduce an efficient mechanical method for harvesting to overcome the practical problems associated with manual harvesting. The major concept of this is to harvest more fruits from one place by minimizing movement in the cultivation. The long handle, fruit picker, stalk holder, cutter, and operating levers are the major components of this device. The remotely operated cutter and fruit gripper are fixed in one end of the 2m long handle and operating levers are attached to other end so that all the fruits within a nearly 2m radius circular area can be harvested from a one place. The performance of the mechanical harvester was evaluated compared to the manual method at a pineapple field in Kurunegala district of Sri Lanka. The Actual harvesting capacity of the device was 385 fruits h 1with 84 efficiency while the manual method recorded it as 210 fruitsh 1 with 64 efficiency when it is operated by males in double row cultivation systems. Results clearly showed that the mechanical method saves more time considerably than the manual method.

 Potato Solanum tuberosum L. is an important crop that plays a major role in food security and poverty reduction to a large proportion of rural farmers in the North West than other parts of Rwanda. However, potato is a perishable product which necessitates an effective choice decision of the market outlet. This paper presents factors influencing smallholder potato farmers’ choice decisions for market outlets in Rwanda. Through a multistage sampling technique, cross sectional data were collected from 585 smallholder potato farmers in Musanze and Nyabihu Districts.Both descriptive statistical methods and econometrics methods were used for data analysis. Multivariate probit model was used to determine the factors influencing smallholder potato farmers’ choice decision to sell to particular market outlets. Results showed that farming experiences, level of education of decision maker, household size, household income, household assets, access to market information and distance to market significantly influenced the smallholder potato farmers’ choice decisions of selling to consumer, retailer, wholesaler, cooperative, collection centres and processors market outlets. The study recommends establishment of structured market systems to improve access to potato market information. This should be supported by agricultural financingfor improved seeds acquisition and other productive inputs to enable farmers to increase surplus potato supplied to market. Improving the farmers’ education in marketing would also help them to effectively deliver potato to efficient market outlet.

Many lessons have been learned since agricultural mechanization was first introduced and adopted across many regions. Eastern UP can apply and learn from the drawbacks and achievements in other countries in its efforts to devise and implement a sustainable agricultural development strategy for the future. Such a strategy can enhance and improve development outcomes and sustainability, support further development of agro industries, and increase scientific and technological innovation and capabilities, while pursuing coordinated urban and rural economic development. This paper focuses on and analyzes mechanization strategies and case studies in postharvest and mechanization that have been carried out over several decades to address differing conditions in countries and their policies towards their rice mechanization systems. As such, the emphasis is on the technologies, policies, practices, strategies, and models that relate to different parts of mechanization systems within specific regions. However, while many mechanization drivers and needs differ from one place to another, a wide range of mechanization elements can be transferred to suit local aspects and conditions in new locations. Furthermore, success stories can help in conceptualizing time and decision making needs, and can also avoid the drawbacks that have appeared in some countries’ mechanization systems, with the goal of leading to faster and more adequate adaptation of different technologies and policies in various implementation stages.There is no consensus on the definition of mechanization, and even when specialists agree on a definition, they sometimes disagree about whether or not it fits particular needs. The term “mechanization” describes the introduction of tools, implements, and machinery for improving the productivity of farm labor and of land it may use either human, animal, or motorized power, or a combination of these. In practice, therefore, mechanization involves the provision and use of all forms of power sources and mechanical assistance for agriculture, from simple hand tools to draught animal power to mechanical power technologies. Hence, agricultural mechanization is the application of mechanical technology and increased power to agriculture, largely as a means to enhance the productivity of human labor and often to achieve results well beyond the capacity of human labor. This includes the use of tractors of various types, internal combustion engines, electric motors, renewable energy, and other methods of energy conversion. Based on the source of power, the technological levels of mechanization have been broadly classified as hand tool technology, draught animal technology, and mechanical power technology. Mechanization also includes irrigation systems, food processing, and related technologies and equipment.

The fruit plants are propagated by two main methods, namely, sexual method and asexual method. Most of the fruit plants do not produce seedlings true to type. Using the asexual method of propagation the fruit plants produce true to type clones of the parent plant. Moreover, these plants also produce uniform yield, fruit size and quality. Although seedling plants produce heavy crop, the fruit size and quality is inferior and do not fetch good return in market. The seedling plants for several fruit crops have long juvenile period and have more vigorous growth habit, which creates difficulty in taking plant protection measures and harvesting of fruits. The fruits of seedling plants do not mature in one stroke and hence, affect the marketing. The asexual methods of plant propagation are of the four types, Cutting, Layering, Budding and Grafting. In this communication we present review on the Sexual method of propagation Seed along with all the asexual or vegetative methods like, Cutting, Layering, Budding and Grafting methods of plant propagation. The cutting method includes root, stem, scion and leaf cutting methods of vegetative propagation. The layering method category encompasses the Natural, Simple, Tip, Compound or Serpentine, Trench, Mound and Air layering methods. The budding method of the asexual propagation includes, T Shield, Inverted T Shield, Chip, I, Patch, Forkert, Flute and Ring Annular Budding methods.

This article presents the results of field experiments of the authors in theoretical and natural conditions. Field experiments were carried out on the territory of the Hodjayakshaba MFY of Kagan district, Bukhara region. The technology of muddy water irrigation for drip irrigation of gardens has been developed. The implementation of drip irrigation technology in intensive gardens has resulted in a 20 60 reduction in water consumption on arable land, up to 50 on mineral fertilizers and up to 30 on fuel and lubricants. Also, the level of ground water does not rise due to the irrigation water requirements of the plant and excessive water supply, low water evaporation from the soil, as well as uniform moisture throughout the field.

Agricultural activities tend to generate a substantial volume of animal and crop residues. Composting is the most economical and ecologically sustainable option to manage farmyard waste. However, it takes approximately three months to complete decomposition and contains lower plant nutrient percentages than inorganic fertilisers. This study aimed to reduce the decomposition time and improve the nutrient content of compost. Aerobic decomposition was enhanced by aeration inside the pile using a blower with 0.5 l min kg airflow. Paddy straw, poultry manure, goat manure, cattle manure and paddy husk ash were mixed in 3 1 1 1 1 ratio respectively as the raw materials and 3 of Eppawala Rock Phosphate was added to the mixture in weight basis. Six piles 150 X 100 X 80 cm were prepared, and three piles were aerated for six hours per day while other three piles were left to decompose under the ambient condition as the control. According to the results, aerated and control piles took 35 days and 65 days to complete the decomposition. Total N, available P, exchangeable K, C N ratio, pH, EC and CEC were analysed in compost samples from aerated after 35 days and controls, and the results were, 20.5 g kg 1, 1.8 g kg 1, 10.4 g kg 1, 7, 8.8, 4.3 mS cm 1, 19.3 cmol kg 1 and 17.8 g kg 1, 1.5 g kg 1, 9.9 g kg 1, 8.5, 8.8, 3.64 mS cm 1, 21.3 cmol kg 1 respectively. Data were analysed using SAS 9.0 software with a 95 confidence interval. The results revealed a significant increment in total N, exchangeable K, C N ratio, EC and CEC in aerated piles compared to controls. And the nutrient composition of both methods was significantly higher than the commercial compost. Therefore, it can be concluded that decomposition time can be effectively reduced and the nutrient level can be increased by artificial aeration and nutrient enrichment, respectively. However, further studies are recommended to study the economic feasibility. D. M. S. H.

 One thing that may affect the students’ perception of mathematics is the attitude of the students towards the subject. This study was conducted to assess the attitude of students towards integral calculus. The subjects of this study were the 94 second year students of the College of Engineering taking up BSAE, BSCE, BSEE and BSME who were enrolled in Integral Calculus. This group of students were a combination of the first timer and repeaters in Integral Calculus. This were the students who were not screened out from the screening examination conducted by the researcher. It employed the descriptive correlational method using the frequency counts, weighted means and analysis of variance.The instrument used in this study was the attitude scale. This instrument was administered to the students before the first screening examination and after the last screening examination.Results revealed that students have favourable attitudes towards integral calculus before and after the screening examination strategy. However, results also revealed that the profile of the students in terms of gender, number of times the student took the subject and the students’ performance on the prerequisite subject has nothing to do or did not influence the attitudes of the students towards the subject.
