A field experiment was conducted at Forage Research and Management Centre, NDRI, Karnal during rabi season in 2013-14 to study the effect of nitrogen application and weed management on growth and yield of fodder turnip (Brassica compestris var. rapa) with four levels of nitrogen (0, 50, 100, and 150 kg N/ha) and four weed management practices (pendimethalin @ 1.0 kg a.i./ha, hand weeding, isoproturon @ 0.75 kg a.i./ha and weedy check) in split plot design. Among the nitrogen treatments 150 kg nitrogen/ha gave the highest growth, yield and better quality of fodder turnip. Application of &nbsp;pendimethalin @1.0 kg a.i. proved better in terms of &nbsp;growth and yield of turnip. Weed control efficiency was 65% with &nbsp;150 kg N/ha and 83.23% with pendimethalin 1.0 kg a.i./ha.

Effect of nitrogen and weed management on weed control efficiency and&nbsp;yield of fodder turnip

<div style="text-align:justify">Background: Brassica rapa (L.) is commonly used as vegetable because of its antioxidant and medicinal properties. Thus, turnip (variety White 4) was characterized by its chemical composition and mineral profile procured from CCS Haryana Agricultural University in Hisar. The effect of solvent on extraction of phytochemicals was investigated.&nbsp; 
 
Methods: Antioxidant potential including total phenolics content (TPC), total flavonoids (TFC), the free radical scavenging activity (DPPH assay) and total antioxidant capacity (TAC) was analyzed.&nbsp; 
 
Result: The aqueous extract contained the highest total phenols (4.56&plusmn;0.02 mg GAE/g) and flavonoids (2.07&plusmn;0.05 mg CE/g) as compare to ethanol and acetone extracts. The DPPH free radical scavenging activity of turnip root extracts was highly variable and increased with increasing concentration levels. The aqueous extract showed the best DPPH free radical scavenging activity at the IC50 value (1.26 mg/mL) followed by ethanol (11.30 mg/mL) and acetone (12.08 mg/mL) extracts. The total antioxidant capacity was highest in aqueous extract (3.45&plusmn;0.03) as compared to ethanol (2.95&plusmn;0.07) and acetone (0.81&plusmn;0.08 mg AAE/g).</div>

Effect of Extraction Solvents on Phytochemicals and Antioxidant Potential of Turnip Roots (Brassica rapa L.)

<div>Background: The field experiment was conducted during 2018-19 experimental farm of Department of Agronomy, College of Agriculture, CSK HPKV, Palampur (H.P.), India. The experiment comprised of ten treatments (maize-wheat, maize-wheat + gobhi sarson, dhaincha-cabbage-frenchbean, sunhemp-vegetable pea-frenchbean, maize + soybean chickpea + linseed, rice-wheat + gram, hybrid sorghum + hybrid bajra-oats + sarson (hybrid), hybrid sorghum + hybrid bajra-ryegrass + berseem, babycorn-broccoli-frenchbean and okra-turnip-tomato) which was laid out in randomized block design with three replications. 
 
Methods: The present investigation was conducted during October 2018-October 2019 (Kharif and Rabi seasons) at an elevation of 1100 m amsl at a latitude of 32&deg;04&rsquo;N and longitude of 76&deg;35&rsquo; E at Bhadiarkar Experimental Farm, Department of Agronomy, CSK HPKV, Palampur, Kangra district of Himachal Pradesh, India. The soil of the experimental area falls in the order of Alfisols with Paleudalf as the great group as per the Udic Moisture Regime. During kharif and rabi season the crop varieties were applied with the recommended dose of N, P2O5 and K2O (kg ha-1). The source of nitrogen (N), phosphorus (P) and potassium (K) were urea, single super phosphate and muriate of potash. 
 
Result: In terms of food for human consumption, highest yield was obtained under the okra-turnip-tomato cropping sequence followed by dhaincha-cabbage-frenchbean and sunhemp-vegetable pea-frenchbean. While in terms of fodder yield, highest was obtained under hybrid sorghum + hybrid bajra-oats + sarson (hybrid) cropping sequence followed by hybrid sorghum + hybrid bajra-ryegrass + berseem. Highest maize grain equivalent yield was obtained with okra-turnip-tomato crop sequence. All other treatments remained superior in comparison to the maize-wheat crop sequence. Maize + soybean-chickpea + linseed emerged to be the best treatment with the highest benefit cost ratio. The treatment comprising okra-turnip-tomato sequence also proved to be the second-best treatment followed by hybrid sorghum + hybrid bajra-oats + sarson (hybrid). Sunhemp-vegetable pea-frenchbean recorded the highest uptake of the available nutrients from soil which was followed by babycorn-broccoli-frenchbean. There was net loss of available nutrients although the loss was less in the sequences with multiple crops during the year. The treatments had no significant effect on the pH and organic carbon content of the soil.</div>
