RESUMO
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) .
RESUMO
Aim: The objective of the research was to study the effect of Integrated Nutrient Management on the yield attributing parameters of kharif onion.Study Design: The field experiment was carried out in Randomised Block Design (RBD).Place and Duration of Study: The experiment was conducted at the Research Farm of the Department of Vegetable Science, Chandra Shekhar Azad University of Agriculture & Technology, Kanpur U.P during the kharif seasons of 2021-22 and 2022-23.Methodology: An experiment was carried out during Kharif season in the years, of 2021-22 and 2022-23 both the year same time at Vegetable Research Farm, Department of Vegetable Science, Chandra Shekhar Azad University of Agriculture and Technology, Kalyanpur, Kanpur. The experiment was laid out in randomized block design with three replications. The treatments consisted of T1- Control: T2- 100% RDF (NPK @ 120:60:80 kg/ha; T3- 75% RDF+ FYM 6 t/ha: T4- 75%RDF+ Vermicompost@2 t/ ha; T5- 75%RDF+FYM @ 3t/ha+vermicompost@1 t/ha ;T6- 75% RDF + FYM @ 3 t/ha + Vermicompost @ 1t/ha+ Biofertilizer (Azotobacter + PSB @ 5 kg/ha each):T7? 50% RDF + FYM @ 12t/ha; T8-50% RDF + Vermicompost @ 4t/ha: T9- 50%RDF+ FYM @ 6t/ha + Vermicompos @ 2t/ha: T10- 50%RDF + FYM @ 6t/ha + Vermicompost @ 2t/ha + Biofertilizer (Azotobacter + PSB @ 5 kg/ha each).Results: Results revealed that the treatment T10 (50% RDF +FYM @ 6 t/ha + Vermicompost @ 2t/ha+ Biofertilizer (Azotobacter + PSB @ 5kg/ha each) performed better with respect to yield attributing parameters characters such as Average bulb weight, A, B, C grade bulb percentage, days takes to harvesting, bolting percentage of bulb and double bulb Percentage.Conclusion: The study underscores the crucial need to shift towards Integrated Nutrient Management (INM), incorporating both organic and inorganic fertilizers. This transition is essential to protect soil fertility, maintain ecosystem health, and ensure sustainable food production for future generations.
RESUMO
Aim: The objective of the research was to study the effect of Integrated Nutrient Management on the vegetative growth of sprouting broccoli (Brassica Oleracea L. Var. italica) Var. Green Magic.Study Design: The field experiment was conducted in Randomised Block Design (RBD).Place and Duration of Study: The experiment was conducted at the Research Farm of the Department of Vegetable Science, Chandra Shekhar Azad University of Agriculture & Technology, Kanpur U.P during the Rabi seasons of 2021-22 and 2022-23.Methodology: During bed preparation, the required quantity of farmyard manure (FYM), vermicompost and biofertilizers was mixed into the soil in individual specified plots according to the treatment. The treatments included T0: Control, T1: 100% RDF @ 120: 80: 60, N: P: K (kg/ha), T2: 75% RDF + 25% N through FYM, T3: 75% RDF + 25% N through Vermicompost, T4: 75% RDF + 25% N through FYM + Biofertilizer, T5: 75% RDF + 25% N through Vermicompost + Biofertilizer, T6: 75% RDF + 12.5% N through FYM + 12.5% N through Vermicompost, T7: 75% RDF + 12.5% N through FYM + 12.5% N through Vermicompost + Biofertilizer, T8: 50% RDF + 50% N through FYM, T9: 50% RDF + 50% N through Vermicompost, T10: 50% RDF + 50% N through FYM + Biofertilizer, T11: 50% RDF + 50% N through Vermicompost + Biofertilizer, T12: 50% RDF + 25% N through FYM + 25% N through Vermicompost and T13: 50% RDF + 25% N through FYM + 25% N through Vermicompost + Biofertilizer. Observations were recorded on plant height (cm) and plant spread (cm) at 30 DAT, 60 DAT and at maturity and on stalk length (cm) and stalk diameter (cm) at maturity.Results: The treatment T11: 50% RDF + 50% N through Vermicompost + Biofertilizer outperformed all the other treatments in terms of plant height (cm), plant spread (cm), stalk length (cm) and stalk diameter (cm).Conclusion: The study emphasizes the vital necessity of transitioning to INM with organic and inorganic fertilizers to preserve soil fertility, ecosystem health, and sustainable food production for future generations.
