The present investigation was carried out in 2019-20 with an aim to assess the fertility status of the head and middle end of minor lift canal command area (602.405 ha), prepare soil fertility maps using Geo-statistical tools and evaluate the spatial variability of different soil parameters. The georeferenced soil samples (211) were collected and analysed adopting standard protocols. Out of total 211 samples about 53% samples (maximum) felled in neutral category and 45% in slightly alkaline pH range. All the samples were having EC <1.0 dSm-1 (non-saline). Maximum samples 83.89% and 99.53% belonged to low category for OC and available N. The spatial distribution of available P in study area revealed that 44.55% samples were found in the medium range followed by 54.03% in the low category. In case of available K maximum (55.45%) samples belonged to high category, followed by (44.54%) samples of medium category. The pH was negatively correlated (-0.153*) with soils available P at the 5% level of significance. The EC values of soil samples showed positive significant correlation with available N (0.225**) and OC (0.215**) at the 1% level of significance. Organic carbon values of soil samples were highly correlated with soil available N (0.550**) and available K (0.212**). GIS based thematic map of soil reaction (pH) showed that 474.245 ha (78.70%) and 117.865 ha (19.60%) area belonged to neutral and slightly alkaline pH category. GIS based thematic map of soil EC showed all the soils of the study area was non-saline. Predicted area of different classes in GIS based thematic map of soil OC and available N showed that maximum 541.7675 ha (90.00%) and 589.460 ha (97.90%) area was recorded in the low category. For available P maximum 312.255 ha (51.80%) area was recorded in the medium category followed by 290.150 ha (48.20%) in the low category. For available K maximum 569.8725 ha (94.60%) area was recorded in the medium category. GIS based interpolated, thematic maps of studied parameters helped in knowing the extent of area in each and every category or classes of fertility, which was not possible with the help of point data. This study will help in guiding for development of resource based land use plan for maintaining the sustainability in soil and crop.

Growth of Rapeseed & Mustard Output in Rajasthan: A Component Analysis

Paper ID- AMA-06-04-2022-11273

To examine the major factors contributing to high growth performance of Rapeseed and Mustard in Rajasthan. The time series data on area, production, productivity and farm harvest prices of rapeseed - mustard grown in Rajasthan were collected and compiled. The data were separated into two decadal periods i.e. Period I (1997-98 to 2007-08), Period II (2008-09 to 2017-18), and Overall Period (1997-98 to 2017-18). Descriptive statistics like CV and CGR have been used to analyze the data. In order to decompose whole transform in the value of production), price effect was also calculated. There was a significant increase in productivity of rapeseed & mustard in the state. The rapeseed & mustard crop recorded highly significant growth in farm harvest price. The yield effect was the most powerful factor in the change of value of production of selected crop during study period in the state. Area under study crop had contributed negative effect towards the value of it and it was the highest negative effect (-715.57%) during overall study period. It may also be noted that the price effect was the powerful force which accounted for more than 70 per cent increase in value of production during period II and 199.40 per cent in overall period. Yield and prices of rapeseed & mustard crop contributed highest increase in value of this crop during the study period. Therefore, in addition to farm harvest prices, productivity of the rapeseed & mustard has also greater bearing on the income of the farmer.

Influence of Irrigation Schedules based on IW-CPE ratio and Hydrogel Levels on Isabgol (Plantago Ovata Forsk.) Productivity

Paper ID- AMA-04-04-2022-11268

A field experiment was carried out at Rajasthan College of Agriculture, MPUAT, Udaipur, to study Response of isabgol (Plantago ovata Forsk.) to hydrogel levels under different irrigation schedules during the rabi seasons of 2018-19 and 2019-20. The experimental design split plot design was used comprises main plot factor four irrigation schedule viz., IW-CPE ratio 0.20, 0.30, 0.40 and 0.50 sub plot factor hydrogel levels which also having four levels viz., control, 2.5, 5.0 and 7.5 kg ha-1 combined having 16 treatment combinations, which were replicated four time. The results revealed that application of irrigation at IW-CPE ratio of 0.50 had significant effect on yield and yield attributes which was at par with IW-CPE ratio 0.40 and both these ratio significantly improve yield over IW-CPE ratio of 0.30 and 0.20 during both years. Application of 7.5 kg hydrogel ha-1 recorded maximum yield and yield attributes which was found at par with application of 5.0 kg hydrogel ha-1 and both these levels significantly enhanced isabgol crop yield and yield attributes over application of 2.5 kg hydrogel ha-1 and control during both years.

Impact of Substrate treatments and Cultivation methods on Yield and Economics of Oyster mushrooms (Pleurotus florida and P. sajor-caju)

Paper ID- AMA-04-04-2022-11267

The present study was conducted to evaluate the effect of different substrates, their pasteurization and cultivation methods on number of days required from spawning to final harvesting, pileus diameter (cm), yield (g/kg dry substrate) and their overall impact on economics of P.florida and P. sajor-caju mushroom cultivation in a mushroom house of 30’ × 60’. P. florida was cultivated in October, 2020 and P. sajor-caju in February, 2021. Amidst different substrate pasteurization treatments used for P. florida cultivation, wheat straw hot water treatment at 70ºC for 20 min was found superior over all the other treatments as the crop duration from spawning to final harvesting was earlier (47.7 days) as compared to paddy straw solarized (57.5 days). Paddy straw hot water treatment was however found more superior in terms of pileus diameter (9.9 cm) and yield (938 g/kg dry paddy substrate. The effect of hanging method of cultivation was found better over rack method in terms of crop duration, pileus size, yield and economics of P. florida. Among different substrate pasteurization and cultivation methods, a significant higher yield of P. florida (1083.7 g/kg dry substrate) was obtained in paddy straw hot water treated and hanging method of cultivation. This substrate treatment and cultivation method was highly remunerative. It gave a maximum net return of Rs. 241394, benefit cost ratio of 3.03: 1 and minimum cost of production (Rs. 24.7 per kg fresh mushroom). Similarly in P. sajor-caju, wheat straw hot water treatment was superior because the crop duration was short (50.0 days) as compared to paddy straw solarized (56.3 days). The paddy straw hot water treatment was found more superior in pileus diameter (11.3 cm) and yield (780.5 g/kg dry substrate). The hanging method was found better over rack method in terms of less crop duration, more pileus size, high yield. A significant higher yield of P. sajor-caju (866.7 g/kg dry substrate) was obtained in paddy straw hot water treated and hanging method of cultivation. This combination gave a maximum net returns of Rs. 113462, benefit cost ratio of 2.43:1, minimum cost of production (Rs. 30.9 per kg fresh mushroom).

Paper ID- AMA-03-04-2022-11264

In this paper electric farm cart powered by super-capacitor battery was developed and its charging and discharging performances was studied. To do this, firstly the electric cart system configuration is introduced. The electric control components are shown. The super-capacitor batteries specification used in the experiment are presented. Next, the charging system consist of constant current (CC)/constant voltage (CV) Buck converter and super-capacitor cell balancing device was developed. Proportional control was proposed to control the current and voltage during charging process. Finally, experiment was done using developed prototype. Current and voltage was monitored using power analyzer during charging and operational. The experimental result shows that the proposed system successfully controls the charging current and balances the battery voltage. The maximum voltage of super-capacitor battery is 16.2V, the peak charging current is 20A and the charging time was less than 1 hour.
