    (2024-02-25) Pranshu Sachan; Dr V K Verma
    Field experiments were conducted during Kharif seasons of 2021 and 2022 at Crop Research Farm, Nawabganj, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur, Uttar Pradesh, India, situated at 125.90 meter altitude, 26.41480 North latitude, 80.23210 East longitude, to study the effect of bio-fertilizer, organic manure and micro-nutrient on scented rice (Oriza sativa L.) The experiment consisted three varieties (PB-1509, PB-1121 and PB-1), three bio-fertilizer and organic manure levels (BGA @ 10 kg ha-1, FYM @10 t ha-1 and BGA @ 10 kg ha-1 + FYM @10 t ha-1) and three nutrient management treatments (NPK- 120:60:60 kg ha-1 only, NPK + ZnSO4 @ 25 kg ha-1 as basal + FeSO4 1% sprayed at tillering stage and NPK + ZnSO4 @ 25 kg ha-1 as basal + FeSO4 1% sprayed at panicle initiation stage). The treatments were accommodated in split-split plot design with three replications. The soil of experimental field was sandy loam in texture having low organic carbon (0.39 %), medium in available nitrogen (179 kg ha-1), low in available phosphorus (13.0 kg ha-1), medium in available potassium (156 kg ha-1), low in available zinc (0.58 mg ha-1) and normal in available iron (7.83 mg ha-1) with normal pH (7.95). Pooled result of two years experimentation indicated that highest value of grain yield (6152.24 kg ha-1), harvest index (36.46 %), grain zinc concentration (35.17 ppm), grain iron concentration (37.78 ppm) and net income (Rs.75749.43 ha-1) was recorded under the variety PB-1121. Application of BGA @ 10 kg ha-1 + FYM @ 10 t ha-1 + NPK (120: 60: 60 kg ha-1) recorded maximum grain yield (5431.41 kg ha-1), harvest index (32.26 %), grain zinc concentration (34.67 ppm), grain iron concentration (37.51 ppm), net income (Rs.61471.54 ha-1) compared to FYM @ 10 t ha-1 and BGA @ 10 kg ha-1 treatments. Application of NPK (120:60:60 kg ha-1) + ZnSO4 @ 25 kg ha-1 as basal + FeSO4 1% sprayed at tillering stage recorded highest grain yield (5214.79 kg ha-1), harvest index (32.10 %), grain zinc concentration (33.73 ppm), grain iron concentration (36.57 ppm) and net income (Rs.57129.86 ha-1) compared to other nutrient management treatments. The interaction effect of varieties, bio-fertilizer and organic manure levels, and nutrient management treatments were found non-significant.

    A field experiment was conducted during Kharif 2022 at student’s Instructional Farm of Chandra Shekhar Azad University of Agriculture and Technology, Kanpur, Uttar Pradesh entitled “Study on Integrated Weed Management in Greengram (Vigna radiata L.)”. The soil of experimental field was sandy loam in texture, pH is slightly alkaline (7.3), low in organic carbon (0.42), available nitrogen (218.10 kg ha-1), medium in available phosphorus (16.0 kg ha-1), available potassium (143.0 kg ha-1) and available sulphur (11.0 kg-1). Experiment consisted of eight treatment laid out in Randomized Block Design with three replications. The treatments consisted of Unweeded control, Two hand weeding at 20 and 40 DAS, Pendimethalin 30 EC @ 1kg ha-1 as PE, Pendimethalin 30 EC @ 1 kg ha-1 as PE + one hand weeding at 20 DAS, Quizalofopethyl 5 EC @ 50g ha-1 at 20 DAS as PoE, Imazethapyr 10 SL @ 100ml ha-1 at 20 DAS as PoE, Pendimethalin 30 EC @ 1kg ha-1 as PE + Quizalofopethyl 5 EC @ 50g ha-1 at 20 DAS as PoE, Pendimethalin 30 EC @ 1kg ha-1 as PE + Imazethapyr 10 SL @ 100ml ha-1 at 20 DAS as PoE. The results revealed that two hand weeding at 20 and 40 DAS recorded the highest grain (10.67 q ha-1) and straw yield (23.84 q ha-1) followed by Pendimethalin 30 EC @ 1 kg ha-1 as PE + one hand weeding at 20 DAS (10.03, 23.09 q ha-1). The predominant weeds of the experimental field consisted of grasses viz., Cynodon dactylon, Echinochloa colonum, sedge such as Cyperus rotundus, and broad leaved weeds such as Trianthema monogyna, Amaranthus viridis. After two hand weeding treatment, the highest weed control efficiency (82.16 %), lowest weed index (6.01 %), weed density (7.75 no m-2) and weed dry weight (4.59 g m-2) at harvest was obtained from Pendimethalin 30 EC @ 1 kg ha-1 as PE + one hand weeding at 20 DAS. This treatment also recorded the maximum plant growth parameters and yield attributes as compared to other weed management practices. Pendimethalin 30 EC @ 1 kg ha-1 as PE + one hand weeding at 20 DAS recorded maximum net return per rupee invested (2.39). Hence, the treatment Pendimethalin 30 EC @ 1 kg ha-1 as PE + one hand weeding at 20 DAS proved beneficial in term of net return and B:C ratio.
