Weed Dynamics exposed to HPPD-inhibitor herbicide (Tolpyralate) with non-ionic surfactant in Maize (Zea mays L.) at foothills of Himalaya
Tolpyralate, an HPPD (4-hydroxyphenyl-pyruvate dioxygenase) inhibitor, is a relatively new pyrazolone herbicide for weed management in maize. Field studies were conducted in two seasons of spring 2016 and kharif 2017 to evaluate the effective dose of tolpyralate 40% SC applied alone or mixed with non-ionic surfactant for weed management in maize as well as its phytotoxic and residual effect on growth and yield of maize and succeeding cowpea fodder and pea crop, at N.E.B.C.R.C. of G.B.P.U.A&T, Pantnagar, U.S. Nagar, Uttarakhand, India. Eight treatments were executed in randomized block design with three replications. The major dominant weed species during both the seasons were Digitaria sanguinalis, Phalaris minor, Echinochloa colona, Panicum maximum among grassy, Chenopodium album, Parthenium hysterophorus, Eclipta alba, Phyllanthus niruri among broad-leaved weeds (BLWs) and Cyperus iria, C. rotundus (3.7%) as sedge. Tolpyralate 40% SC as PoE with surfactant resulted in 50-100% weed control, depending on the weed species and its doses over tolpyralate 40% SC without surfactant. Tolpyralate 40% SC PoE at 60 g/ha achieved the highest grain yield of maize and was statistically at par with its lower dose 50 g/ha and tembotrione 34.4% SC 120 g/ha (standard check), during both the seasons. The tolpyralate 50 g/ha with non-ionic surfactant attained a higher net return (Rs. 92601 and 58203/ha) and B: C ratio (2.6 and 1.6) than without surfactant during spring 2016 and kharif 2017, respectively. Also, no phytotoxic symptoms and residual effect on succeeding crop were observed at any doses of tolpyralate 40% SC.
Analyze the influence of internal damage of maize seeds on germination based on Micro-CT image technology
The germination and growth of maize seeds are directly related to the damage inside the seeds. This paper discussed the relationship between the internal damage of the maize seed after compression and the seed germination rate. Using Micro-CT technology to analyze the characterization of the internal mechanical damage of the seeds. Distinguished the internal tissues and crack damage according to the difference of grayscale value. By counting the number of pixels in different grayscale value intervals, the proportion of each tissue of the seed in the slice layer was calculated. The degree of internal damage was analyzed. After cultivating the tested seeds, the germination results were compared with internal damage to verify the relationship between the germination rate of seeds and internal damage. The results show that the average crack damage of seeds after being subjected to loads of 250 N, 300 N, 350 N, and 400 N are 2.87%, 3.07%, 4.31%, and 4.58%, respectively. At this time, the germination rates of the seeds are 95%, 90%, 25%, and 10%. According to the results, Micro-CT technology can be used to analyze the internal damage of maize, revealing the influence of the internal damage of maize seeds on germination.
Energy Use, Efficiency, and Distribution in Malaysian Oil Palm Cultivation
Effective energy management is critical for oil palm cultivation in long- term productivity and profitability. It is imperative to perform investigations into where, when, why and how the energy is being used in the oil palm cultivation activity. This study presents energy use analyses in oil palm nursery and field cultivation in Malaysia. The data of energy inputs use in the oil palm cultivation were retrieved using a combination of actual field measurements and secondary source documents from relevant reputable publications. Annual total energy inputs for a complete oil palm field cultivation was estimated to be 1118.34 MJ/palm/year. Oil palm field cultivation takes the largest share with 99.27% (1110.18 MJ/palm) of the total energy input while oil palm nursery cultivation was 0.73% (8.16 MJ/seed). Machinery utilization is the primary source of energy input in oil palm nursery and field cultivation, accounting for 90.29 % and 96.08% of the total energy inputs, respectively. The energy efficiency of the oil palm cultivation is 4.38, which is considered as an energy-efficient crop cultivation since the output-input ratio is larger than one.
Energy Use, Field Performance and Greenhouse Gas Emission Evaluations of Pesticide Spraying Operations inW etland Rice Cultivation in Malaysia
Pesticide application conducted to offer the needed protection to rice plants against weed, disease, insect, and pest infestations. The aim of this study is to investigate the field performance, field time distribution, energy expenditure, mechanization Index, and greenhouse gas emissions from chemicals spraying operation. This conducted study revealed that the wetland paddy fields under transplanting method show 16.3% higher mean effective field capacity, 0.7% lower mean field efficiency, 4.1% lower mean fuel consumption, and 9.5% higher mean operation speed than the fields under broadcast seeding method. The time-motion analysis showed that the laborers spent only 69% of their total working time in the actual spraying task on the crops while the balance 31% of the total operation time was used in filling and mixing pesticides and water in the sprayer tank. The highest contributor to energy expenditure was pesticide energy where it represented 83% to 84.5% of the total energy followed by fuel energy with 14.8% to 13.4%. The total human energy obtained through the conventional method was 34.7% higher mean than the physical human energy recorded using the Garmin method. The heart rate of the worker in performing the spraying operation was the highest compared to the heart rate of the worker in performing the other operations. The total GHG emissions were 66.3 to 92.4 kg CO2eq/ha and chemicals pesticides represent the highest contributor it represented 78.9% to 82.7% of the total GHG emissions. The average mechanization index of the operations in wetland rice cultivation in Malaysia was 70.4%. Fertilizing, planting (broadcasting), and chemicals spraying operation have the lowest mechanization index in wetland rice cultivation.
Geotagged Application for Durian Trees using Aerial Imagery and Vegetation Indices Algorithm
Durian demand has increased considerably, and it has gained popularity in the market. Under Industrial Revolution 4.0, precision agriculture is expanding globally with a wide range of digital technologies that provide the farming industry with information to improve farm productivity. The objectives of this study are to geotag the durian trees and to compare several Vegetation Indices (VIs) algorithms (Visible-Band Difference Vegetation Index (VDVI), Visible Atmospherically Resistant Index (VARI), Normalized Green-Red Difference Index (NGRDI), Red-Green Ratio Index (RGRI), Modified Green-Red Vegetation Index (MGRVI), Excess Green Index (ExG), Color Index of Vegetation (CIVE), and Vegetativen (VEG)). One hundred sixty durian trees at the Durian Valley in Kluang (Johor), were tagged, which consist of four sample trees for each treatment. Every two weeks of ground data such as the height of trees, canopy width, girth’s diameter, node distance, pH value, moisture content, electrical conductivity (EC) reading, and leaf sizes were exported into the QGIS software and joined with the tagged durian trees. The aerial imagery data captured the durian plantation area using Red Green Blue (RGB) sensor with a 100 m flight attitude. pH, EC, and moisture content were interpolated using Inverse Distance Weighted (IDW) technique. The processed image by VIs and geotagged trees could help farmers to identify the problem areas in the farm and monitor durian plantation effectively.
