The experiment was conducted in split-plot design with three replications. The treatment consisted of four crop establishment, methods viz. conventional wheat (CT-wheat), zero-tilled wheat (ZT-wheat) + rice residue @ 3t/ha, ZT-wheat without residue and stale-seed bed wheat (SSB-CT-wheat) in the main plot and 4 N management protocols viz., control (No-N), recommended N schedule (RDN), modified N schedule and leaf colour chart (LCC)-guided N scheduling in sub-plot. The growth parameters, like dry matter and indiceslike CGR, RGR and LAI were observed highest at 90 DAS and decreased thereafter. They remained highest in ZT+R and LCC-guided N application treatments. Various root parameters like, root length, root volume and root surface area were recorded maximum in ZT+R, followed by ZT, SSB-CT and lowest in CT. A 14.2 % increase in grain yield was recorded under ZT+R compared to CT. Also, about 15.4% increase in grain yield was recorded under LCC-guided N application-based N management compared to RDN. Also, under different establishment methods, a saving of 33.3% N under LCC-guided N application was recorded in ZT, SSB-CT and CT.

Indiscriminate use of inorganic fertilizers leads to N losses from the agro-ecosystem which lower soil fertility, crop yield and impair the environment. Nlosses in agro-ecosystem majorly occur through ammonia volatilization and denitrification. Integrated application of inorganic and bio-fertilizer could reduce the N losses by synchronizing nutrient supply and demand of crop. Therefore, a field experimentwas conducted at ICAR-Indian Agricultural Research Institute, New Delhi during rabi season of 2018-19 for determining the effect of inorganic and bio-fertilizer on N losses and yield of wheat. The experiment was laid out in randomized block design (RBD)replicated thrice. The experiment comprising of eight treatments involving, control (unfertilized, Tc), Azotobacter (Ta), Mycorrhiza (Tm), Azotobacter + Mycorrhiza (Tam), NPK recommended (Tr), Tr + Azotobacter (Tra), Tr + Mycorrhiza (Trm), Tr + Azotobacter + Mycorrhiza (Tram). Results have revealed that Tram showed the highest soil available P, and K. Application of Tram recorded the higher yield (6.41 ha1) compared to Tr where it was obtained up to 5.81 ha1. The ammonia volatilization and denitrification losses were reduced by 33.7% and 34.2% respectively, with application of Tram as compared to Tr. Hence, integrated application of inorganic and bio-fertilizers could be recommended in farmers field for reducing N losses as well as increasing wheat productivity.

The experiment comprised of seven post emergence herbicides (clodinafop 9% + metribuzin 20% (RM) (ACM-9), clodinafop 12% + metribuzin 42% (RM) (Shagun), metribuzin, isoproturon, sulfosulfuron, meso+iodosulfuron and pinoxaden) and their integration with malathion at different doses along with weed free and weedy check treatment. Among the treatments where herbicides were applied without integration with malathion, significantly taller plants, more dry matter accumulation, higher number of tillers and LAI were observed under pinoxaden, which remained significantly higher than all other herbicides, whereas, the values of these parameters considerably reduced after the integration with malathion as compared to solitary application of herbicides, except malathion fb pinoxaden. Weed free plots followed by pinoxaden at 50 g/ha and malathion fb pinoxaden at 1000 fb 50 g/ha resulted in higher number of tillers and more dry matter accumulation. Weed free plots recorded higher yield attributes i.e. effective tillers (408 tillers/m2) and higher grain yield (5764 kg/ha) followed by application of pinoxaden at 50g/ha. The maximum weed controlefficiency at harvest was recorded under weed free situations and was at par with malathion fb meso+iodosulfuron at 1000 fb 14.4 g/ha and malathion; Shagun at 1000 fb 270 g/ha whereas, minimum WCE was recorded with isoproturon at 1000 g/ha (34.29 %). Integrated application of herbicides and malathion recorded lower weed density, dry weight of Phalaris minor and higher weed control efficiency as compared to solitary application of herbicides.

Front line demonstrations (FLDs) were conducted on 16 farmers fields each year to demonstrate the impact of improved agro-techniques on production and economic benefits. HD 2967 variety was demonstrated with the use of bio-fertilizers- Azatobactor and PSB and zero-tillage technology. It was revealed that the demonstrated technologies under FLDs resulted in an augmented mean yield of 4.73 t/ha having an edge of 18.22% higher yield over Local Check (farmer's practice) of 4.01 q/ha. Induction of demonstration technology recorded a mean technology gap (TG) of 1.79 t/ha,extension gap (EG) of 0.72 t/ha and technology index (TI) of 27.41 t/ha. The FLDs recorded an additional return of 18350.72 f/ha and 15221.25 / ha with B: C ratio of 1.44 and 1.58 for demonstration and 0.78 and 1.06 for Local Check during 2017-18 and 2018-19, respectively. Unavailability of improved high yielding varieties of wheat in relation to climate change was found to be most confronting constraint. Therefore, the wheat productivity could be increased with the adoption of new wheat varieties andrecommended improved package of practices and technologies.

The experiment was laid out in split plot design in which the precision nitrogen (N) management as main plot and chemical weed control as sub plot treatments with four replications. The precision N management treatments consisted of Nt - Absolute or Control, N_2 - State recommendation (SR) @ 120:60:40, N_3 - LCC Based N application, N_4 - SPAD Based N application and four sub plot treatments (chemical weed control) W_1- Control (unweeded), W_2- Pinoxaden @ 40g a.i./ha+Metsulfuron methyl 5% (20g a.i./ha) applied at 30-35 DAS, W_3- Fenoxaprop-p-ethyl 10 WP (100 g a.i./ha) 30-35 days after sowing (DAS), W_4- Clodinafop 15 WP (100 g a.i./ha) 30-35 DAS. It was observed that chemical methods of weed control significantly reduced the weed density and dry weight of weeds effectively over control, hence increasing the yield of wheat peaking at 47.83 q/ha. The LCC based nitrogen application also gave significantly higher grain yield (46.97 q/ha) as compared to other treatments. The protein content (8.22%) and protein yield (393.64 kg/ha) was found to be maximum with application of Pinoxaden followed by Fenoxaprop whereas LCC based N application gave higher protein content (8.10%) and protein yield (381.34 kg/ha) as compared to SPAD based N application during both the years of experimentation.

The experiment was laid out in split plot design with three replications. Two varieties (DWRUB 52, DWRB 92) were kept in main plots and seven fertility levels (control, 80,100,120% recommended NPK, 80% NPK + 1%K foliar spray, 100% NPK + 1% K foliar spray, 120% NPK + 1% Kfoliar spray at grain filling stage) were kept in sub plots. Emergence time and count was almost similar in all treatments. Var. DWRB92 showed non-significantly higher plant height, leaf area, dry matter accumulation, effective tillers, ear length, kernel plumpness, protein content, grain and malt yield than DWRUB 52. On the other hand, var. DWERUB 52 produced significantly higher number of grains per spike than DWRB92. Application of NPK upto 120% recommended dose increased significantly the plant height (98.9 cm), leaf area (2.94), dry matter accumulation (111.2g), effective tillers (376), ear length (9.49 cm), number of grains per ear (28.59), 1000-grain weight (45.65g), grain protein content (10.4%), grain (4.63 t/ha) and malt yield (3.74 t/ha) over 80% recommended dose and control. Foliar application of K was proved beneficial for yield contributing and quality traits. Maximum net returns (41108/ha) and B:C ratio (1.22) were obtained at 120% recommended NPK+1% K spray at grain filling stage.

Br. emend Stuntz] to potassium fertilization and stress mitigating chemicals" was conducted at Agronomy farm, S.K.N. College of Agriculture, Jobner (Rajasthan) during kharif, 2019 on loamy sand soil. The sixteen treatment combinations consisting of 4 treatments each of potassium levels (control, 10, 20 and 30 kg/ha) and stress mitigating chemicals (Control, thiourea, thioglycolic acid and thiosalicylic acid) were testedin randomized block design with three replications. Results indicated that progressive increase in level of potassium up to 20 kg/ha significantly improved the growth and yield determining characters of pearl millet viz., crop growth rate, effective tillers per plant, grain yield, stover yield over preceding levels. Further enhancement in potassium level to 30 kg/ha could not increase the above parameters significantly. However, plant height was recorded significantly higher due to potassium levels over control only. Results further showed that plant height, CGR, effective tillers/plant, grain and stover yields were significantly enhanced by foliar application of stress mitigating chemicals. By and large, application of thiourea being at par with TGAproved significantly superior over rest of the treatments in respect of the above parameters wherein all the chemicals being at par proved superior to control.

    查看更多>>摘要：Adoption of suitable agri-hortisystem (AHS) and different level of deficit irrigation scheduling (DIS) can improve growth attributes and productivity of Indian mustard under residual soil moisture of semi-arid region. A field experiment was conductedin rabi season in the year 2020-21 at research farm of ICAR-Indian Agricultural Research Institute to evaluate the interaction effect of AHS with three different levels of deficit irrigation scheduling via drip on growth, productivity and quality parameters of Indian mustard. Various suitable Agri-Horti Systems viz. moringa (Moringa oleifera L.), karonda (Carissa carandas L.), phalsa (Grewia asiatica L.), aonla (Phyllanthus emblica L.) and guava (Psidium guajava LJ were taken with different level of deficit irrigation viz. 0.6 IW/CPE, 0.4 IW/CPE and rainfed under sandy loam soil. The results revealed that the interaction effect of 0.6 IW/CPE treatment with moringa based AHS outperformed the others treatment combination. The interaction effect of Moringa based AHS 0.6 IW/CPE had significant effect on plant height, number of primary and secondary branches. However, interaction effect between AHS and DIS for growth attributes viz. plant height, number of primary and secondary branches did not differ significantly for different AHS under rainfed and 0.4 IW/CPE DIS. The interaction effect between AHS and DIS on seed, stover and biological yield showed significant difference among the treatments. Quality parameters viz. oil content(%) as well as oil yield(kg ha1) was recorded highest with the treatment combination of moringa with 0.6 IW/CPE.
