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).

Development of Supercapacitor Battery Powered Electric Farm Cart for Light Agricultural Duties

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.

Effect of Different Liquid Biofertilizers and Varying Fertility on Yield of Cluster Bean [Cyamopsis tetragonoloba (L.) Taub]

Paper ID- AMA-03-04-2022-11263

The experiment was conducted on farm of Rajasthan Agricultural Research Institute (RARI), Durgapura, Jaipur (Raj.) to study the effect of different liquid biofertilizers and fertility levels on growth, yield and quality of cluster bean (Cymopsis tetragonoloba). The test crops were raised on field during july to november kharif-2018 and 2019. The experiment was laid out in factorial randomized block design (FRBD). The treatment details of experiment comprised with two factors (1) eight treatment of liquid biofertilizer: control-no biofertilizers (L0), Rhizobium (L 1), PSB-phosphorus solubilizing bacteria (L2), KMB-potassium solubilizing bacteria (L 3), SSB-sulphur solubilizing bacteria (L 4) , Rhizobium + PSB (L 5 ), Rhizobium + PSB+ KMB (L 6 ) and Rhizobium + PSB+ KMB + SSB (L 7) and (2) three treatment of fertility levels: 100 % recommended dose of fertilizers (F1),75% RDF (F2) and 50 % RDF (F3) and total number of treatment were 24. The maximum increase in yield attributes viz., seed yield (kg ha-1), straw yield (kg ha-1) and biological yield (kg ha-1) observed in 100 % RDF (F1) with Rhizobium + PSB+ KMB + SSB (L 7) but the combination of 75% RDF with Rhizobium + PSB+ KMB + SSB (L 7) found the similar effect with 100% RDF with Rhizobium + PSB+ KMB + SSB (L 7). However, the combined treatment of 75% RDF with Rhizobium + PSB+ KMB + SSB (L 7) noticed significantly superior than other treatment.
