This study developed an axial air-suction drum seed-metering device without a special vacuum pump and associated pipeline facilities, greatly simplifying the structure of the air-suction drum seed-metering device, which aimed to solve the problems of complex structure and difficult maintenance of traditional air suction drum seed-metering device. The geometric model of the seed-metering device was established by SOLIDWORKS. In addition, numerical simulation tests were carried out on the seed-metering device based on CFD to verify the feasibility of the theoretical operation of the seed-metering device. The seed-metering device was processed and a test bench was built for physical testing, which verified the feasibility of the actual operation of the seed-metering device. The bench test results showed that when the fan speed reached 2100 rpm, the adsorption rate of the seed-metering device on tomato seeds, pepper seeds, and eggplant seeds reached more than 86.39%,87.22%, and 93.06%, respectively. Besides, when the fan speed reached 2400 rpm, the adsorption rate of the seed-metering device on tomato seeds, hot pepper seeds, and eggplant seeds all reached more than 95%, which demonstrated that the seed-metering device has good seed suction performance despite its straightforward design.

Based on the principle of moment balance, this paper designs a fertilizer application amount online detection device, which is mainly composed of two major parts: the fertilizer guide mechanism and the fertilizer metering and discharging mechanism.Under the electromagnetic reversing and buffering of the fertilizer guide mechanism, the fertilizer discharged into the device falls alternately into the storage box of the two metering units of the metering and discharging mechanism. Once the gravity of the fertilizer in the storage box is greater than the suction of the electromagnetic sucker, the fertilizer discharging board is automatically opened for fertilizer discharge, and the metering pulse signal is accumulated once. Meanwhile, the fertilizer guide plate is driven by the electromagnetic commutator to reverse the material, and then another storage box is started for fertilizer storage and metering. In this approach, online detection of fertilizer flow can be realized by repeatedly guiding and reversing and metering the incoming fertilizer. According to the single metering fertilizer quality and the number of metering pulse signals, the fertilization amount can be calculated in real-time.The performance of the device was verified by bench test. The test results indicated that: The established fertilizer application detection model is a quadratic function (R2>0.98), and the verification error was less than 3.73% in the detection of alternating cycle fertilizer discharge; the coefficient of determination (R2) and the root mean square error (RMSE) reached 0.992 and 9.858 respectively, indicating high detection accuracy of the device is.

The present study was conducted in Brgy. Dangcol, Balanga City, Bataan to evaluate the effect of bagging the whole panicle (cluster) of carabao mango fruit with waxed paper bag as compared to traditional method of bagging and without bagging in terms of fruit yield and quality as well as in cost-benefit analysis. Results revealed that fruits bagged per cluster using waxed paper (T3) obtained the highest number of marketable fruits (130.60) and highest total weight of 34.21 kg while the number and weight of XL fruits with no bag (T1) were significantly higher as compared to those bagged in cluster using waxed paper (T3). Insect damage was observed in fruits bagged per cluster using waxed paper bag (T3) while there is a scab in fruit with no bag (T1). Meanwhile, there is a wind scar observed in the two bagging methods (conventional bagging method and fruits bagged per cluster using waxed paper bag). All bagging treatments were comparable in terms of physical and chemical characteristics except for peel color which is lighter green in bagged fruits. In terms of income, mango fruits bagged per cluster using waxed paper bag (T3) had the highest gross income of PhP 3,056.27 while the highest net income and ROI was recorded in fruits bagged in conventional method (T2) earning PhP 616.09 per tree with 27.23% ROI. The conventional method (T2) also obtained the lowest cost per tree (PhP 2,262.36) while the lowest cost per kilogram (PhP 73.05) and cost per fruit (PhP 19.14) was recorded in mango trees bagged per cluster using waxed paper bag (T3).

Shallots are one of the horticultural commodities which are the same as other commodities. This study aims to find out the comparison of the level of business risk and farmers' preferences for risk in the highlands represented by Purworejo Village, Ngantang District, Malang Regency and in the medium plains represented by Tawangargo Village, Karangploso District, Malang Regency. This research was determined by purposive sampling using simple random sampling method using 66 samples of shallot farmers. Analysis of the data used is farming analysis, analysis of production factors of cobb-douglass, analysis of coefficient of variation (CV) and Likert scale. Based on the results of this study indicate that the production factors that significantly influence the shallot farming are seeds, NPK fertilizers, ZA fertilizers, and labor. While the level of risk of farming in the highlands, namely Purworejo Village, Ngantang District, Malang Regency, is lower than the level of risk in the Medium plains, namely Tawangargo Village, Karangploso District, Malang Regency. In addition, farmers' preferences for sources of risk in the highlands tend to be more daring to face risks, while the preferences of farmers in the lowlands are more neutral in facing risks.

This study aimed to determine the potential residues of the rice crop from the second planting period, which were fed with a mixture of pistia compost and rice straw of various compositions with the Brassica rapa L. pakcoy. The study used a factorial randomized block design, the first factor was 7 levels divided into 5 compost mixtures and 2 comparison treatments (NPK fertilizer treatment and control) as follows; control, M1 : 100% pistia, M2 : 75% pistia + 25% rice straw, M3 : 50% pistia + 50% rice straw, M4 : 25% pistia + 75% rice straw, M5 : 100% rice straw and M6 : NPK ., and the second factor is the presence or absence of addition of compost in the second rice planting period divided into 2 levels; 1. (+) = addition of compost, 2.(-) = no addition of compost. The results showed that the residue of composting for the second planting period of rice had a positive effect on soil fertility, especially in the repeated addition of compost, which showed a very significant positive priming effect. The highest positive priming effect was shown by the medium of high-quality compost, namely the treatment of 100% pistia (M1+) seen in the growth parameters and yield of Brassica rapa L pakcoy. The increase in growth due to the addition of repeated compost was 5.10% to 14.24%, and an increase in yield was 5.41% to 11.11% in various treatments of mixed compost media. The treatment with repeated addition of compost gave a significant response to the P uptake of Brassica rapa L plants but the treatment without compost (-) showed 36.72% higher than the treatment with the addition of compost (+).

Long beans are classified as seasonal plants that can begin to be harvested approximately 6-9 weeks after planting and then periodically until approximately 3 months after planting, then the plants experience aging which results in low flower and fruit production. The harvest can be in the form of young pods which contain lots of vitamins A, B and C; medium for the production of mature seeds containing protein, fat and carbohydrates. The productivity achieved by farmers is still much lower when compared to the potential yield of long beans which can reach 20-25 tons/ha of fresh pods. The purpose of the study was to determine the increase in the productivity of long bean plants through the application of organic vermicompost fertilizer. The results of the study provide the following conclusions: There was a significant effect on the treatment of vermicompost on all observed variables, namely plant length, number of leaves, number of fruit (pods) per plant, and fresh weight of fruit (pods) per plant; and giving vermicompost as much as 1.50 kg per plant (treatment K6) gave a better average effect than other treatments at the end of the observation on the variables of plant length, number of leaves, and number of fruit (pods) per plant, although it was not significantly different by giving vermicompost as much as 1.25 kg per plant and 1 kg per plant on the variable total fresh weight of fruit (pods) per plant studied.

This study was conducted to determine the differences in income, level of feasibility and level of enthusiasm or attitude of farmers in cultivating sugarcane varieties of Cenning and Bululawang. The research was carried out in Badang Village, Ngoro District, Jombang Regency from May to July 2021. The research method used was descriptive analysis method, which means analyzing income that has been ongoing or based on reality. In addition, the multi-attribute fishbein model is also used to calculate the interest or attitude of sugarcane farmers to plant cenning and Bululawang varieties.The results showed that the income obtained from sugarcane farming of the Cenning variety was Rp. 24.522.620,- while the sugarcane of Bululawang variety was Rp. 18.438.820,-. Sugarcane farming of the cenning variety in Badang Village, Ngoro District, Jombang Regency is feasible to be cultivated with an R/C Ratio of 1.61. Meanwhile, the Bululawang variety of sugarcane farming is also feasible with an R/C Ratio of 1.49. Based on fishbein analysis, it was found that the attitude of sugarcane farmers in Badang Village, Ngoro District, Jombang Regency (Ao) towards the cenning variety was 37,28. It is interpreted that the farmer's total attitude (Ao) towards the cenning variety is in the third range (36-51) which is agree (S). So it can be concluded that sugarcane farmers in Badang Village, Ngoro District, Jombang Regency prefer cenning sugar cane to Bululawang sugarcane varieties.
