Studies on effect of different soil types and moisture regimes on seed hydration value of various soybean varieties

Paper ID- AMA-24-05-2022-11404

The laboratory experiment on “Studies on effect of different soil types and moisture regimes on seed hydration value of various soybean varieties” was conducted during the season 2020-21 in CIC laboratory of Soil Science and Agricultural Chemistry Department, College of Agriculture, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani, to find out the seed hydration value and germination in different soybean varieties at different soil moistures in three types of soil. This study was carried out in petri plates with four soybean varieties JS-335, MAUS-71, MAUS-158 and MAUS-162 at four soil moisture levels of 50, 75, 100 and 125 percent field capacities in Vertisols, Entisols and Inceptisols soils. The treatments were replicated two times in FCRD design and observations were taken at regular time interval of 6 hours up to 96 hours from sowing. The results obtained from investigation revealed that the germination parameters and seed hydration value for different soybean varieties were clearly influenced by different soil moistures in different soil types. Amongst all varieties, variety MAUS-162 showed highest germination at different soil moistures and lowest was noted in variety JS-335. In vertisols and Inceptisols, the highest seed hydration value was reported in variety MAUS-162 with earliest germination among all varieties in all soil types. Better germination for soybean varieties were observed at soil moisture of 75 and 100 percent field capacities. Vertisols and Inceptisols showed early and better germination for soybean seeds. Among all soybean varieties, MAUS-158 and MAUS-71 showed lower seed hydration value so can be suitable for rainfed cultivation.

Evaluation of paper mill sludge, calcium silicate, and stromatolyte as a liming material

Paper ID- AMA-23-05-2022-11403

Soil acidity is one of the major problems of South East Asia, especially India, Nepal, Srilanka, Bhutan, and adjoining areas. However, limiting is a costly practice managed through industrial and natural sources. Our study attempted to evaluate the effectiveness of three cheap and readily available liming materials viz paper mill sludge, calcium silicate, and stromatolite under laboratory conditions. Acid soil (pH-4.50) collected from Malkangiri, Odisha, was amended with liming materials following an utterly random design that consisted of six different treatment combinations replicated thrice. All the necessary observations were made on a fortnightly basis following standard procedures. The results indicated that amongst the liming material used, paper mill sludge application tremendously increased the soil pH from 6 to 7.1 when applied at an equal dose of the tested liming materials. The neutralizing value of Papermill sludge, stromatolyte, and calcium silicate was 60, 80, and 80 percent, respectively. Although liming is costly practice, it is also evident that regular liming is not pleasant for farmers and crops. Therefore, when employed, a double dose of lime requirements has shown skewed increment in soil reaction favouring farmer, crop, and soil environment as a whole. In the control treatment, no change occurred, but the application of F.Y.M. due to buffering property neutralized the exchange acidity, acidity due to Al+3, acidity due to H+ and raised the pH slightly. The application of liming materials at two doses neutralized the exchange acidity 1.10 to 0.62cmol(P+)/kg with calcium silicate followed by 1.12 to 0.90 cmol(P+)/kg withstromatolyte, followed by 1.12 to 0.90cmol(P+)/kg with paper mill sludge. The acidity due to Al+3 0.61 to 0.42cmol(P+)/kg withstromatolyte, followed by 0.61 to 0.50with calcium silicate, followed by 0.63 to 0.51cmol(P+)/kg with paper mill sludge. The acidity due to H+ 0.48 to 0.45cmol(P+)/kg withstromatolyte, followed by 0.46 to 0.38 cmol(P+)/kg with paper mill sludge followed by 0.46 to 0.12cmol(P+)/kg with calcium silicate. The pH from 5.0 to 5.9 withstromatolyte, followed by 5.2 to 6.0 with calcium silicate, followed by 5.0 to 6.1with paper mill sludge. The double dose of liming material @ 0.2 LR with F.Y.M. gives the highest pH and neutralization of H+& Al+3 compared to the single-dose @ 0.1 LR.

Evaluation of the Elite Strains of Acid Lime (Citrus aurantifolia Swingle) for the Quality Attributes Under Subtropical Conditions of Jammu Province

Paper ID- AMA-23-05-2022-11402

Genetic variability in available germplasm must be studied in order to develop improved cultivars through planned breeding programmes. As a result, the research work was carried out to evaluate the quality parameters of acid lime genotypes. Total of seventy lime genotypes were selected randomly from different areas of Jammu region. Results of the study revealed that among leaf characters most of the genotypes had medium colour of leaf blade and elliptic lamina shape. Among biochemical characters, highest TSS (8.890brix) was found in genotype JMU-Nag(70) and lowest TSS was observed in genotype JMU-Kat (14) (6.300brix). The genotype JMU-Log (4) had the lowest acidity (6.18 percent), while genotype JMU-Nag had the highest acidity (8.35 percent) (70). The highest content of ascorbic acid (36.81 mg/100ml juice) content was found in genotype JMU-Nag (70), maximum juice per cent (57.13 per cent) was recorded in the genotype JMU-Nag(70) and the highest pH (3.71) was observed in genotype JMU-Balli(62). Hence, the overall studies indicated that the genotype JMU-Nag(70), JMU-Jib(36) and JMU-Pana(41) being productive and superior in quality stands for selection and further improvement.

Metribuzin and Pendimethalin effects on weed dynamics, crop growth and yield of wheat

Paper ID- AMA-23-05-2022-11399

A field experiment conducted at Agricultural Research Farm, Division of Agronomy, BHU, Varanasi to evaluate the efficacy of herbicide to control of weeds in wheat crop. Weed flora of the experimental field was dominated by broad leaved weeds like Solanum nigrum, Anagallis arvensis, Chenopodium album, Vicia sativa, Melilotus indicus, Rumex dentatus, and Medicago denticulatum, narrow leaved weeds like Cynodon dactylon, Phalaris minor and sedges like Cyperus rotundus. In the experimental field weeds were controlled by pre-emergence application of herbicides viz.,pendimethalin 30% EC @ 600 g ha-1, pendimethalin 30% EC @ 900 g ha-1, pendimethalin 30% EC @ 1200 g ha-1, pendimethalin 30% EC @ 1500 g ha-1, metribuzin 70% WP @ 210 g ha-1and weed free (two hands weeding). All herbicidal treatment compare with Untreated Control (Weedy check). Among all herbicidal treatment pendimethalin 30% EC @ 1200 g ha-1 application is effective to control Phalaris minor, with WCE was 89.21%. Metribuzin 70% WP @ 210 g ha-1 have efficacy to control broad-leaf weed effectively and some narrow leaf weed. The highest grain yield observed in hand weeding (5693 kg ha-1) followed by herbicidal treatments, pendimethalin 30% EC @ 1200 g ha-1 (5078 kg ha-1). Highest B: C ratio (2.11) is achieved with the application of pendimethalin 30% EC @ 1200 g ha-1.

Design and experimentation of an intelligent control system for a small self-propelled electric transplanter

Paper ID- AMA-23-05-2022-11398

The purpose of this paper is to design an intelligent electric transplanter to improve the efficiency of greenhouse vegetable transplanting and the accuracy of precise plant spacing.kernel technologies of the transplanter include mechanical design, adaptive fuzzy PID control, and Android terminal control. The main body of the mechanical part is composed of the seeding cups and the hanging cup type planetary wheel planting mechanism. An adaptive fuzzy PID algorithm is proposed to accurately control the rotating speed of the driving motor and the working motor, and simultaneously, the driving device and the planting device are perfectly matched. In experiments with transplanting frequency of 30-40 plants per minute, transplanted seedlings spaced 30-40 cm apart, and a controlled rate of 40 plants per minute, it was found that the maximum and average control errors of the transplanter's motor speed are respectively 12.76% and 10.83% if the motor speeds are between 20-40 rpm. When compared with a conventional PID controller, the adaptive fuzzy PID controller can reduce the maximum and average control errors by 6.8% and 6.25%, respectively. Moreover, the average error rate of planting spacing, the maximum error rate of line spacing, and the success rate of transplanting are respectively 6.21%, 13.37%, and 95.67%. the control software of the mobile phone is utilized to conduct state detection and transmission to the cloud. The position of the transplanter can be monitored online and the travel speed, transplanting speed and transplanting spacing of the transplanter can be adjusted in real time.
