Effect of Weed Management Practices on Weed Dynamics and Productivity of Sweet Corn (Zea mays L. Ssp saccharata) under Organic Production System

Paper ID- AMA-01-03-2022-11171

A field experiment was conducted during 2019-20 at the Agronomy Farm, Rajasthan College of Agriculture, Udaipur. The experiment was laid out in a RBD with three replications and twelve treatments viz. T1: Hoeings at 20 and 40 DAS, T2: Power weeding at 20 DAS + hoeing at 40 DAS, T3: Stale seedbed + two hoeings at 20 and 40 DAS, T4: Stale seedbed + power weeding at 20 DAS + hoeing at 40 DAS, T5: Stale seedbed + hoeing at 20 DAS + straw mulch at 30 DAS, T6: Stale seedbed + plastic mulch at sowing, T7: Soil solarization + two hoeings at 20 and 40 DAS, T8: Soil solarization + power weeding at 20 DAS + hoeing at 40 DAS, T9: Soil solarization + hoeing at 20 DAS + straw mulch at 30 DAS, T10: Soil solarization + plastic mulch at sowing, T11: Weed free check and T12: Weedy check. On the basis of experiment result it was revealed that T10 and T6 at all stages of observation and T9 and T5 at 30 DAS and T11 up to 50 DAS were the most effective treatment in reducing weed density and weed dry matter accumulation as compared to other treatments. Like weed dry matter accumulation T10 and T6 gave 100 per cent weed control efficiency at all stages of observation. The highest green cob and fodder yield were recorded in T10 (12.97 and 26.32 tonnes ha-1) which was statistically at par with T9 (12.77 and 24.57 tonnes ha-1, respectively).

Effect of nitrogen and spacing on flower yield of spider lily (Hymenocallis littoralis L.)

Paper ID- AMA-26-02-2022-11168

The present investigation entitled “Effect of nitrogen and spacing on flowering of spider lily (Hymenocallis littoralis L.)” was undertaken at College of Horticulture, Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli during the year 2019-20 and 2020-21 by considering the commercial importance of spider lily under Konkan agro-climatic conditions. The experiment was laid out in a split plot design using four levels of nitrogen and three levels of spacing with three replications along with the common dosage of phosphorous (150 kg ha-1) and potassium (100 kg ha-1). The observations were recorded on various growth namely number of flower buds per plant, flower buds per ha (lakh ha-1), flower yield per plot (kg plot-1) and flower yield per ha (t ha-1) and most of the parameters were differed significantly at highest levels of nitrogen and spacing. Flower yield and yield attributing characters viz., the highest number of flower buds per plant (46.84), flower buds per ha (16.01 lakh), flower yield per plot (8.50 kg) and flower yield per ha (6.56 t ha-1) were recorded with the treatment N1 (300 kg ha-1). With regards to spacing, the highest number of flower buds per plant (36.23), flower buds per ha (19.37 lakh), flower yield per plot (9.48 kg) and flower yield per ha (7.31 t ha-1) was recorded in S3 (30 × 60 cm). However, the interaction effect of treatment combination N1S3 (300 kg N ha-1; 30 × 60 cm) recorded the highest number of flower buds per plant (58.52), flower buds per ha (29.49 lakh), flower yield per plot (16.06 kg) and flower yield per ha (12.39 t ha-1).

Trend of Area, Production and Productivity of Major Oilseed and Cash Crops in Context of Food Security: Rajasthan, India

Paper ID- AMA-26-02-2022-11167

Indian economy is an emerging economy, but it is still an agricultural economy because here, most people earn their livelihood from agriculture. The present study for temporal changes in Rajasthan time series, data on area, production and yield per hectare of oilseed and cash crops were collected from 1976-77 to 2018-19. Rajasthan state as a whole was selected for the study. The time-series data were collected on area, production, and yield of selected four Rajasthan crops from the Directorate of Economics and Statistics (DES), Directorate of Agriculture (DOA) and Rajasthan State Agriculture Department. The crops included were sesamum, soybean, rapeseed & mustard and cotton. The area under selected in Rajasthan changed remarkably from 1976-77 to 2018-19. The area under sesamum was reduced, which was shifted towards pulses, oilseeds and cereal crops like moong, urad, soybean, rapeseed & mustard and wheat. The area under soybean, rapeseed & mustard and cotton, had increased during the study period. During the study period, the average total production and yield increased to unprecedented levels in all the selected crops. The area under sesamum reduced during the study period. Therefore, technological support through varietal improvement and extension support is required.

On Farm validation of technology for enhancing the productivity and profitability of maize intercropped with rajmash under high hills of north-western Himalayas.

Paper ID- AMA-24-02-2022-11164

A field experiment was conducted during kharif 2011 and 2012 at Sartangal farm of regional research horticulture station of SKUAST-Jammu by taking total sixteen treatment combinations with four cropping systems viz., sole maize, sole rajmash, maize + rajmash in 1:1 (1 rows of maize alternating with 1 row of rajmash) and maize + rajmash in 2:1 (2 rows of maize alternating with 1 row of rajmash), and four nutrient management techniques viz., T1=control, T2=100% NPK (RDF, recommended dose of fertilizers N:P2O5:K2O, T3=75% RDF + remaining 25% N through farmyard manure (FYM) T4=50% RDF + remaining 50% N through farmyard manure (FYM). Among cropping system maize + rajmash (1:1) produced highest maize grain equivalent yield (MEY, 7772 kg/ha, net returns (INR 52190/ha), B:C ratio (1.81) and Whereas among nutrient management techniques,75% RDF + 25% N (FYM) produced highest MEY (7681 kg/ha), net returns (INR 52585/ha) and B:C ratio of 1.88. These best experimental results were further validated by conducting five OFTs in farmers field selecting two dominant sites namely Gwari and Sartangal where maize and rajmash were intensively grown to validate the performance with respect to increase productivity and profitability of maize (Bioseed-9621) intercropped with rajmash (local). The results of OFT highlighted that the percent increase in MEY, Net returns, B:C ratio and energy productivity was 46.27, 55.64, 23.83 and 60.86 respectively under new recommendations (One row of maize followed by one row of rajmash with fertilizer dose of 75 kg/ha urea, 68 kg/ha DAP and 25 kg/ha MOP and 3t/ha FYM) over existing recommendations [Mixed cropping using seed rate of 8:1, with fertilizer dose 100 kg/ha urea, 90 kg/ha DAP and 33 kg/ha MOP (Package and Practices)] besides improved soil fertility due to line sowing, use of higher seed rate and use of balanced fertilizer doses in New recommendations. Hence new recommendations increased productivity and profitability of maize intercropped with rajmash thus recommended under high hills of north west Himalayas.

Technologies used in plant protection and weeding implements for optimising their performance: A Review

Paper ID- AMA-24-02-2022-11163

Weed control is one of the most time-consuming tasks, and manual weeding is inefficient due to labor costs, time, and tedium. Chemical weed management technologies have helped to alleviate these negative aspects. However, the growth of herbicide-resistant weeds, their environmental impact, and the growing desire for chemical-free foods have encouraged researchers to investigate alternate weed management strategies. A prototype of a walking-type battery-operated boom sprayer cum weeder was developed. The attachment was made to suppress inter-row weed plants mechanically. A brushless dc motor powers the mechanical weeding attachment. One of the most challenging aspects of this project was appropriately designing the weeding attachment and the sprayer for spraying. Both attachments would be joined with a machine to do mechanical weeding and spraying without affecting the crops. In this paper, various researches on sprayers, weeders, and combined configurations of sprayers & weeders have been discussed along with their working principles.
