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.

Studies on variability in Seedling Tree Population of Pecan nut [Carya illinoensis (Wang) K Koch.] for nut and kernel characteristics in Jammu and Kashmir

Paper ID- AMA-21-05-2022-11395

Survey was undertaken to explore the existing variability in Pecan [Carya Illinoensis (Wang) K Koch.] of seedling tree origin in Jammu province for utilization its potential in future breeding programmes. Out of total seedling tree population in the region 60 healthy and bearing trees were marked to access the available genetic variability in pecan nut germplasm. Based on the characterization and evaluation of nut and kernel characteristics pecan trees excelled in major economically important characteristics. All the 60 seedling trees exhibited extreme variation for individual traits. The results revealed that nut shape in ventral view varied from circular to ovate, nut shape in cross section varied from narrow oblate to circular, shape of apex from lateral view varied from rounded to acute, length of tip varied from short or absent to long, area covered by spots on nut varied from small to large, kernel adherence to shell varied from weak to strong and intensity of brown colour in kernel varied from light to dark.
