“…Also the higher canopy spread on the weed free plots contributed greatly to the higher crop vigour on the weed free plots. This result agrees with earlier report of Korav et al (2020) who reported better growth of groundnut when the crop is allowed to grow in the midst of less weed canopy. They further reported that weed disturbed the mineral supply, has allelopathic effect on the crop and thereby reducing the growth and development of groundnut.…”

The experiment consisted of ten treatments arranged in a randomized complete block design and replicated three times. Treatments includes keeping plots weed free initially for 3, 6, 9, 12, 15 weeks after planting (WAP) and keeping plots weed infested initially for 3, 6, 9, 12, 15 WAP. Data collected on weed cover score, weed dry matter production, crop vigour score, canopy spread, pod yield and numbers were subjected to analysis of variance and treatment means were separated using least significant difference at P ≤0.05. The results showed that total weed dry matter production increased with weed infestation period and decreased with weed free period. Also, there was significant increase in pod yield and count when plots were kept weed free for 6 WAP and more. Our findings showed that, the highest percent weed accumulation, weed removal, pod yield loss and pod yield gain all occured between 3 and 6 WAP. Therefore, the critical period of weed interference in groundnut is between 3 and 6 WAP. Also, there was 83.4% pod yield loss in groundnut when weed was allowed to compete freely with the crop throught crop life cycle.

“…This implies that less weed-crop competition is needed for good crop growth. This corroborates the findings of Korav et al (2020) who reported restriction in foliage coverage of groundnut as the canopy development of weeds increased.…”

“…Weed pressure levels for them as sole crops illustrate that not all crops have the same competitive ability against weeds: barley presents very low weed infestation compared to the other two, with pea ranking the highest. Other factors influence the performance in the presence of weeds, such as plant architecture, vigor, or allelopathy [37,38].…”

Faba bean is an important legume crop wordwide, grown both for food and feed. As for many legume crops, postemergence weed control is difficult. The aim of this work was to assess potential of intercropping on weed management by assessing the effect of mixing faba bean with different crops (wheat, barley, and pea) on weeds in the South of Spain. Four field trials were conducted over four consecutive seasons, and results found that addition alternate intercropping of faba bean and barley achieved high levels of weed control, both for coverage and biomass (92.7% and 76.6%, respectively). Intercropping with wheat did not reduce weed coverage but did decrease weed biomass by 46.1% as compared to faba bean monocrop. Intercropping with pea did not provide significant reductions for weed coverage neither for weed biomass. The diversity of the weed community was not altered by the different crop combinations tested. Additional experiments under controlled conditions were carried out to determine a possible role of barley allelopathy in weed suppression. A strong allelopathic effect entailing a reduction in the number of plants and biomass was detected for four weeds: Sinapis arvensis, Polypogon monspeliensis, Matricaria camomilla, and Medicago trucatula. It can be concluded that intercropping faba bean with barley is an excellent strategy for weed control in the Southern Spain.

“…It was a unique choice for cultivation in nontraditional maize growing locations due to its short duration, adaptability to various cropping methods, and appropriateness for cultivation in all seasons. Another benefit of cultivating Babycorn is the biomass (green fodder) that remains after harvest [2].…”

A field experiment was conducted during kharif season (2022) at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P.). The treatments consisted of 3 levels of Phosphorous (30, 40, 50 kg ha-1) and 3 levels of micronutrients (Zn-0.5%), (B-0.5%) (Fe-0.5%). The experiment was laid out in Randomized Block Design with 10 treatments and replicated thrice. The results reported that the application of 50kg ha-1 Phosphorous + 0.5% Zinc (treatment -7) recorded maximum plant height (160.7 cm), Maximum plant dry weight (74.60 g plant-1), No. of corns per plant (1.77), corn length (19.3 cm), corn yield (10.06 t ha-1), green fodder yield (28.43 t ha-1). Maximum gross return (1,20501.00 INR ha-1), net return (77,444.00 INR ha-1) and B:C ratio (1.80) were recorded in (treatment -7) that is with 50 kg ha-1 Phosphorous + 0.5% Zinc.
