SUMMARY

A field experiment was conducted at the All India Co-ordinated Research Project on Sorghum, Haradanahalli Farm, Chamarajanagara during kharif season of 2021 to study the response of fodder sorghum variety CNFS-1 to different sowing intervals and varied levels of seed rate. The experiment was laid out in split plot design with three replications. The main plot consists of four different intervals of sowing and subplot with three levels of seed rate. The data revealed that, among the sowing intervals, sowing at first fortnight of May recorded significantly higher plant height ( 255.58cm), leaf : stem ratio (0.244), leaf area (6966.08cm²), stem diameter (8.83mm), green fodder yield
(62.32t/ha), dry fodder yield (16.19t/ha), gross returns (Rs. 1,24,636 /ha), net returns (Rs. 69,627/ha) and benefit: cost ratio (2.26) compare to other dates of sowing. While, the seed rate of 55kg/ha has recorded significantly higher growth and yield components with higher gross returns (Rs.1,02,970/ha) compared to other levels. However, maximum leaf : stem ratio (0.211), leaf area (6426.67 cm²), stem diameter (8.25mm), net returns (Rs.52,381/ha) and benefit cost ratio (2.04) was observed with a seed rate of 50 kg/ha.

SUMMARY

A field experiment was conducted at Vegetable Research Farm, Chaudhary Charan Singh Haryana Agricultural University; Hisar to study the influence of irrigation sources, FYM and fertility levels on yield, harvest index and agrometeorological indices of pearlmillet.The experiment consisted of 16 treatment combinations with two irrigation sources [canal and treated sewage water], two levels of farm yard manure [2.5 and 5 t/ha] that assisted in main plots and four fertility levels [control, 50, 75 and 100% RDF (recommended dose of fertilizer, 156.25 kg N and 62.5 kg P₂O₅ /ha)] that assisted in subplots in split-plot design using three replications. Irrigation sources (canal and treated sewage water) did not differ significantly in respect of yield and agrometeorological indicesviz.thermal, heliothermal and photothermal use efficiencies. Significantly higher value of thermal, heliothermal and photothermal use efficiencies in respect of seed and stover yield were found with the application of 100 percent recommended dose of fertilizers (RDF) over control and 50 percent RDF. Neither the irrigation sources nor the fertility levels brought any significant variation in respect of attraction and harvest index of pearlmillet.

Key words: Yield, pearlmillet, irrigation sources, FYM levels, sewage and canal water

SUMMARY

Efficacy of different herbicides in clusterbean was studied at Research Farm, Department of Agronomy, CCS Haryana Agricultural University, Hisar during kharif 2018 and 2019. Digera arvensis, Trianthema portulacastrum, Echinochloa colona and Cyperus rotundus dominated the weed flora of the experimental field. Application of pendimethalin + imazethapyr (RM) at 1000 g/ha resulted in lower weed density, less dry matter accumulation by weeds and provided higher weed control efficiency of 97.6 and 85.8% during 2018 and 2019, respectively followed by pendimethalin + imazethapyr (TM) at 750 + 50 g/ha and pyroxasulfone + pendimethalin 106 + 1000 g/ha (TM). Highest seed yield (1047 kg/ha) was recorded with weed free treatment. Among different herbicides, pendimethalin + imazethapyr (RM) at 1000 g/ha resulted in more pods/plant, taller plants and higher seed yield (907 kg/ha) followed by pendimethalin + imazethapyr (TM) at 750 + 50 g/ha (887 kg/ha) as pre-emergence application. Weedy conditions resulted in more than 60% reduction in seed yield as compared to weed free

SUMMARY

A field experiment was conducted during summer season of 2020 at the college farm, Navsari Agricultural University, Navsari, to study the “Effect of varieties, FYM and nitrogen levels on summer fodder pearl millet under south Gujarat condition.” The soil of the experimental field was clayey in texture having medium to poor drainage capacity, good water holding capacity, low in available nitrogen and organic carbon, medium in available phosphorus and available potassium. The soil was neutral in reaction with normal electric conductivity. Total twelve treatment combinations comprising of two varieties (V₁ : GAFB-4 and V₂ GFB-1), two levels of FYM (F₁ : control and F₂: 5.0 t FYM/ ha) and three levels of nitrogen treatment (N₁ :75% RDN/ha, N₂ : 100% RDN/ha and N₃ :125% RDN/ha) were evaluated in factorial randomized block design with three replications. Fodder pearl millet variety GAFB-4 receded significantly higher plant height at 30 DAS (42.65 cm), at harvest (142.16 cm), leaf : stem ratio (0.41), number of leaves per plant (11.61), green fodder yield (272.69 q/ha), dry matter yield (74.70 q/ha), and crude protein yield (536.0 kg/ha) over variety GFB-1. Net
returns (Rs 60601/ha and B: C ratio (3.86) was also found maximum under the same treatments.
Incorporation of 5.0 t FYM/ha significantly increase plant height harvest (142.11 cm), leaf: stem ratio (0.41), green fodder yield (280.38 q/ha), dry matter yield (76.34 q/ha), crude protein content (7.54 %) and crude protein yield (579.48 kg/ha) over control. The higher net returns (Rs 84115/ha) and B: C ratio (4.76) was incurred under the application of 5 t FYM/ha and control, respectively. An application of 125 % RDN/ha significantly increase plant height at 30 DAS (44.13 cm) and at harvest (144.82 cm), leaf: stem ratio (0.43), number of leaves per plant (12), green fodder yield (279.32 q/ha), dry matter yield (75.58 q/ha), crude protein content (8.06%), crude protein yield (615.18 kg/ha) and higher net returns (Rs. 62246/ha) and B: C ratio (3.89) over 75 % RDN. over.

SUMMARY

The mechanical characteristics of wheat straw were evaluated in terms of shear and tensile strength with respect to variety, moisture content and inter node position. The parameters were determined for two varieties (WH – 1105 and HD – 2967) at three levels of moisture content (5, 10 and 15% (wb)) and five internode positions (IN1, IN2, IN3, IN4 and IN5). The results showed that shear strength decreased with increase in moisture content, whereas tensile strength increased with an increase in moisture content. The shear and tensile strength both increased from first internode to fifth internode in both the varieties. The shear strength of WH – 1105 was significantly higher (30 %) than HD – 2967 at each internode and all levels of moisture content. Similarly, the tensile strength of WH – 1105 variety was 10 % higher than HD – 2967 variety. The presence of carbon and oxygen as
key elements in both the varieties was confirmed by the Energy Dispersive Spectroscopy (EDS). The WH – 1105 wheat straw contains higher carbon content as compared to HD – 2967 which provided a strong reason for better mechanical properties.

SUMMARY

Wheat and barley occupy the most prominent position in terms of production and acreage in developing countries. Plant-parasitic nematodes are a well-recognized constraint to production of cereals in fields. Cereal cyst nematode, Heterodera spp., is known worldwide as parasites of wheat and grasses. Cereal cyst nematode can cause significant economic yield losses alone in combination with other biotic and abiotic factors. The damage caused by this nematode can be enormous when it occurs in a disease complex, particularly in areas subject to water stress. For managing this nematode, an experiment was conducted in earthen pots of 1 kg soil capacity under screen house condition during 2017-18. There were four treatments with three replications of each. Castor cake (10g/pot) was mixed in soil 10 days before sowing (DBS). Neem oil @ 10 ml/kg seed was used as seed treatment. Among all these treatments, minimum number of cysts was observed in neem oil @10 ml/kg seed treatment followed by castor cake @ 10 g/pot (10 DBS) and subsequently improved the plant
growth parameters of wheat.
