ABSTRACT
The present investigation entitled “Effect of weed management practices on growth, yield and quality of okra Abelmoschus esculentus (L.) Moench)” was conducted at Vegetable Research Farm, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur during kharif season 2022. The experiment was laid out in Randomized Block Design with seven different treatments viz. T1 = Pre-emergence application of Pendimethalin @ 6 ml /L, T2= Post emergence application of Quizalofop-ethyl @ 0.040 kg/ha ,T3 = Pre-emergence application of pendimethalin @ 6 ml/L + one hand weeding at 40 DAS , T4 = Post emergence application of Quizalofop-ethyl @ 0.040 kg ha-1 at 25 DAS + one hand weeding , T5 = Pendimethalin @ 6 ml /L as pre-emergence + Quizalofop-ethyl @ 0.040 kg ha-1 at 25 DAS , T6 = Weed free check (Three hand weeding) 20, 40 and 60 DAS , T7 = weed check control replicated thrice. The result of the study revealed that at 30 DAS maximum plant height (30.96cm) was reported in treatment T3 : Pre-emergence application of Pendimethalin @ 6 ml/L + one hand weeding at 40 days of sowing whereas at 60 and 90 DAS maximum plant height (75.50 and 113.53 cm) was reported in T6 : Weed free check (Three hand weeding) 20, 40 and 60 DAS. Maximum number of branches per plant (4.60)at 60 DAS was found in T3 : Pre-emergence application of Pendimethalin @ 6 ml/L + one hand weeding at 40 DAS and 90 DAS maximum number of branches per plant (5.86) was reported in T6 : Weed free check (Three hand weeding) 20, 40 and 60 DAS. Maximum number of nodes (17.83 ) at 60 days after sowing was noticed in treatment T3 = Pre-emergence application of Pendimethalin @ 6 ml/L + one hand weeding at 40 DAS and 90 Days after of sowing maximum number of nodes () was in treatment T6 = Weed free check (Three hand weeding) 20, 40 and 60 DAS. Maximum Pod diameter( 1.74cm) , fruit weight (12.88gm ), pod length( 14.1cm) , number of pods per plant( 25.66 ) , pod yield per plant ( 304.73gm) , pod yield per hectare (16.91 t), TSS( 3.2 Brix), crude fibre (8.46%) and cholorophyll content (1.18 mg) and relative cholorophyll content (54.39) .
ABSTRACT
This review paper critically assesses the challenges and opportunities associated with Radio Frequency Identification (RFID) adoption in agriculture. RFID technology has the potential to revolutionize agricultural processes, offering benefits such as improved supply chain management, enhanced livestock tracking, and data-driven decision-making. However, its implementation also faces various obstacles, including technical, economic, and integration challenges. Through an in-depth analysis, this review explores the socio-economic and environmental implications of RFID adoption, considering its impact on labor dynamics, job displacement, rural communities, energy consumption, and waste generation. The paper concludes with insights into the future prospects of RFID integration in agriculture and provides strategic recommendations for overcoming challenges and ensuring responsible adoption.
ABSTRACT
Extensively, it is imperative to address the pervasive issue of nutrient deficiencies among humans and animals in numerous underdeveloped regions. To tackle this challenge, a field experiment was conducted to investigate the impact of foliar applications of Zinc, Boron, and Iron on the growth, yield attributes, and overall yield of chickpea (Cicer arietinum L.) varieties during the Rabi seasons of both 2018-19 and 2019-20. The field experiment was meticulously designed using a Split Plot Design, wherein three distinct chickpea varieties (V1-KGD-1168, V2-Radhey, and V3-KWR-108) were assigned to the main plots. The subplots were dedicated to seven micronutrient treatment combinations, namely (M1-Control), (M2-Zinc @ 0.5%), (M3-Boron @ 0.2%), (M4-Iron @ 0.1%), (M5-Zinc @ 0.5% + Boron @ 0.2%), (M6-Zinc @ 0.5% + Iron @ 0.1%), and (M7: Zinc @ 0.5% + Boron @ 0.2% + Iron @ 0.1%). Consequently, a total of 21 treatment combinations were meticulously replicated three times. The findings of the experiment unveiled that the Radhey variety significantly influenced various parameters, including plant height, the number of branches per plant, fresh plant weight, 100-seed weight (17.21, 17.25g), seed yield (2118, 2228 kg ha-1), gross return (112396, 113628 INR ha-1), net return (83154, 83616 INR ha-1), and the benefit-to-cost ratio (B: C ratio) (2.84, 2.79) of chickpea for both the years 2018-19 and 2019-20, respectively. Regarding the micronutrient treatments, the foliar application of Zinc @ 0.5% + Boron @ 0.2% + Iron @ 0.1% exhibited a notably positive impact on plant height, the number of branches per plant, fresh plant weight, 100-seed weight (16.94, 16.97g), seed yield (2162, 2276 kg ha-1), gross return (114634, 116076 INR ha-1), net return (85041, 85712 INR ha-1), and B: C ratio (2.87, 2.82) of chickpea during both the years 2018-19 and 2019-20, respectively. Based on these compelling results, farmers are strongly advised to cultivate the Radhey variety of chickpea while implementing foliar applications of Zinc @ 0.5% + Boron @ 0.2% + Iron @ 0.1% for enhanced growth and higher yields.
