Background: Weeds are primary factors that adversely affect growth, yield and seed quality of summer green gram, which can be minimized with adoption of proper weed management practices. This field experiment was conducted to find out the effective weed management practice in summer green gram (Vigna radiata) under zero tillage condition. Methods: In this field-laboratory investigation conducted during summer season 2019 on different herbicides were applied to manage weeds in summer green gram. Eight treatments were applied based on various application windows. In the field and laboratory, the collected samples were determined for growth parameters, nutrient uptakes, seed yield and seed quality of summer green gram. Result: The result revealed that weed free treatment recorded higher growth parameters like, plant height, number of branch/plant, number of leaves/plant and root biomass which was statically at par with Shaked (Propaquizafop + Imezathyper) as post-emergence (POE) at 20 DAS and Pendimethalin as pre-emergence (PE) followed by one hand weeding 20 DAS. Same trends were also observed in seed yield, nutrient content and uptake by seeds. Seed quality parameters like germination per cent (98.00), shoot (25.63 cm) root (14.20 cm) and seedling length (39.83 cm), seedling dry weight (0.16 g), vigour index I (3903.33) and vigour index II (14.96) was higher under weed free followed by Shaked (Propaquizafop + Imezathyper) and Pendimethalin as (PE followed by one hand weeding 20 DAS over weed check.

The Impact

A Field experiment was conducted at Agronomy instructional Farm, Rajasthan College of Agriculture, MPUAT, Udaipur (Rajasthan) during 2016-17 to find out the impact of new generation herbicides in green gram.  The results revealed that all growth and yield characters of blackgram were significantly affected by distinct weed control practices. A similar trend was also observed in weed parameters. Higher seed yield (13.8 qha-1) and higher weed control efficiency (88.97%) were recorded under application of acifluorfen sodium + clodinafop propargyl (370 g a.i. ha-1) at 3-4 leaf stage and which comparable with pre-emergence application of pyroxasulfone +pendimethalin (TM) 127.5+1000 g a.i/ha, imazethapyr+ quizalofop (TM) use at 70 + 60 g a.i/ha at 3-4 leaf stage, imazethapyr 70 g a.i/ha 3-4 leaf stage, imazethapyr + imazamox (RM) use at 70 g a.i/ha at 3-4 leaf stage, pendimethalin fb quizalofop 1000 + 60 at pre-emergence & 3- 4 leaf stage, imazethapyr + pendimethalin (RM) 1000 g a.i/ha as pre-emergence, propaquizfop 75 g a.i/ha at 3-4 leaf stage, weedy check and two hand weeding twice at 20 & 40 DAS. They also recorded improvement in yields and net returns by 65.22% over weedy check. These herbicide ready-mixes may be a promising weed management strategy for the green gram grown in the Southern Rajasthan.

Background: To study effect of various spacing and weed management practices on weed control, growth parameter, yield and yield attributes of pigeon pea variety Pusa Arhar-16, field experiments were conducted at Student’s Research Farm, Khalsa College Amritsar, Punjab, India during kharif season of 2019-20.Methods: The experiment was laid out in Split plot design with three replications. The treatments comprised of four different spacing i.e. S1 (30×10 cm), S2 (30×15 cm), S3 (40×15 cm) and S4 (50×25 cm) which were considered as main plot treatments and three weed management practices W1 (weedy check), W2 (pendimethalin @ 1.5 kg a.i. ha-1 at 1DAS) and W3 (rice straw mulch) as sub-plot treatments.Result: It was found that maximum plant height (218.2 cm) and highest leaf area index (2.104) was recorded in treatment S1 (30×10 cm) whereas treatment S4 (50×25 cm) was superior in rest of growth parameters viz. maximum crop growth rate (0.85 gram per plant per day), number of primary branches (18.2 per plant) and number of secondary branches (13.8 per plant). Among yield and yield attributes, spacing S1 (30×10 cm) showed maximum grain yield (16.29 q ha-1) and stover yield (49.29 q ha-1) whereas, maximum number of pods per plant (154.6), pod length (4.83 cm), number of seeds per pod (3.90) and 100-seed weight (7.14 grams) were recorded in spacing S4 (50×25 cm). The weed management treatments showed non-significant effect on growth and yield parameters due to weed suppressing ability of the crop. which might be due to weed suppressing ability of the crop. It may be concluded that pigeon pea cultivar Pusa Arhar-16 performed better in narrower spacing of 30×10 cm due to its dwarf nature and it also showed good smothering effect on the weeds due to its smothering effect.

Horizontal expansion of pulse production can be achieved by introduction of short duration pulse crop like, green gram (Vigna radiata (L.) R. Wilczek) under agri-horti system. Response of green gram under different agri-horti system and weed management practices is lacking. Therefore, an agronomic trial was conducted during monsoon season of 2011 at Agricultural Research Farm, Rajeev Gandhi South Campus, Banaras Hindu University, Barkachha, Mirzapur, Uttar Pradesh, in split plot design, consisting of three agri-horti systems [guava, custard apple and open field] in main plots and six weed management practices [pendimethalin 1000 g/ha (PE), imazethapyr 125 and 200 g/ha (PoE), 1-HW (20 DAS), 2-HW (15 and 30 DAS) and weedy check] were assigned to sub plots and replicated thrice. Green gram variety ‘Samrat’ was sown as per standard agronomic package of practices on August 5, 2011 in open field as well as within the alleys of, 5-year old, guava and custard apple agri-horti system. Agri-horti systems, did not significantly (P<0.05) affect the growth, yield attributes, yield and nutrient content in green gram. The weed management practices significantly affected the CGR, RGR and yield of green gram. Application of imazethapyr 200 g/ha recorded 79.08% reduction in weed biomass and 11.38% lower seed yield as compared to weedy check and 2-HW (15 and 30 DAS), respectively. 2-hand weeding effectively reduced weed biomass (88.07%) and showed highest yield (888.79 kg/ha), and CGR (13.61 g/day) followed by imazethapyr 200g/ha yield (787.66 kg/ha) and CGR (13.14 g/day).
