“…Crops grown simultaneously enhance the abundance of predators and parasites, which in turn prevent the build-up of pests, thus minimizing the need of using expensive and dangerous chemical insecticides. Srikanth et al in (2002) also reported that shoot borer incidence was non-significant in different intercrop combinations.…”

To increase the area, production and productivity of sugarcane and legumes/oilseeds for increasing the profit of the farmers', field experiments were conducted at Chaudhary Charan Singh Haryana Agricultural University, Regional Research Station, Karnal during 2005-06 and 2006-07 followed by demonstrations on intercropping of legumes/oilseed with sugarcane at farmers' field in Kaithal district during 2009-10 and 2010-11. Cane yield did not reduce significantly due to intercropping except raya during 2005 -06. The percent incidence of pink borer, shoot borer, top borer and root borer remained below economical threshold level (ETL). In all intercropping systems, total land equivalent ratio (LERt) was greater than unity, indicated yield advantage for the intercropped plots. Land equivalent coefficient (LEC) followed the same pattern as LERt. Total area time equivalent ratio (ATERt) values showed an advantage (22-28 %) with all intercropping systems than sole cropping with maximum advantage from sugarcane + chickpea. Sugarcane was more competitive than pea and lentil intercrops, whereas, raya and chickpea were more competitive than sugarcane. Higher competitive ratio values for the intercrops (CRi) indicated that all the intercrops were more competitive than sugarcane. Total values of actual yield loss (AYL) showed an advantage of 22-38% from intercropping compared to sole cropping. Highest monetary advantage index (MAI) value was obtained from sugarcane + pea intercropping system (75779). However, the minimum MAI was obtained from sugarcane + lentil intercropping system (62382). Demonstrations on intercropping at farmers' field also resulted in higher gross returns, returns over variable cost and benefit: cost ratio.

“…To reduce the amount of herbicides used for weed control in sugarcane, both for economical and environmental reasons, an Integrated Weed Management (IWM) involving a combination of cultural, mechanical, biological, genetic, and chemical methods has become a priority (Swanton and Weise 1991). To achieve this, there is a need for better understanding of sugarcane-weed interactions and identification of the critical periods of weed competition with respect to crop growth, the dry matter accumula-tion by the weed community increased during the entire period, weed interference in sugarcane caused 40% of yield loss, the critical period for weed control was between 74 and 127 days after planting and 75 DAP may be reduce shoot borer populations, (Srikanth et al 2002 andKuva et al 2003). Duration of critical periods of weed interference on 5% acceptable cane yield loss ranged from 2.5 to 14 weeks after planting, (Yirefu et al 2013).…”

and 2016/17 seasons, to study the effect of intercropping soybean (cover crop) with sugarcane crop, sole sugarcane and weed control treatments i.e. (Stomp at 1.75 l/f. hand hoeing twice at 25 and 45 days after planting and unweeded check) as the integrated weed control on fresh and dry weight of weeds (g/m 2 ) and yield of primary crop (sugarcane) and secondary crop (soybean) which intercropping with sugarcane in natural infested soil by weeds. The experiment was laid out in randomized complete block design (RCBD) under split plot arrogant with four replication, intercropping treatments was put in the main plots and weed control treatment in split plots with four replications for each treatment.The infestation rates in field experiments were 8.79 ton/fed broad-leaved weeds, 8.66 ton/fed grassy and 17.45 ton/fed total weeds in 2015/16 season and 11.86 ton/fed broad-leaved weeds, 7.05 ton/fed grassy weeds and 18.91 ton/fed total weeds in 2016/17 season. Intercropping soybean with sugarcane reduced fresh weight of total weeds at 75 days after planting about 56 to 59%, as well as improvement sugarcane yield attributes traits such as stalk length, diameter, number of stalk/fed and number of internodes/stalk which reflected on cane yield and sugar yield ton/fed. in both seasons, compared to sole sugarcane.Weed control by hand hoeing twice and Stomp at the rate of 1.75 l/f. reduced fresh weight of total weeds at 75 days after planting by about 81 to 85% and 69 to 72%, respectively, compared to unweeded check, and increased stalks and top yield (ton/fed.) of sugarcane than unweeded check in average of both seasons.The interaction effect between intercropping soybean with sugarcane and weed control treatments decreased were significantly fresh weight of total weeds, improved sugarcane yield attributes traits and cane and top yield (ton/fed.) of sugarcane compared to the sole sugarcane and without weed control. Intercropping soybean and without weed control treatments reduced fresh weight of total weeds at 75 after day planting by 71.71 and 70.01% than sole sugarcane and without weed control treatments. Hand hoeing twice reduced fresh weight total weeds at 75 after day planting by 93.78 and 87.91% with sole sugarcane and by 87.78 and 87.66% with intercropping soybean in 2015/16 and 2016/17 seasons, respectively, compared to sole sugarcane and without weed control. Using Stomp at 1.75 l/fed reduced fresh weight of total weeds at 75 after day planting by 85.24 and 84.35% under intercropping soybean and by 75.45 and 80.42% under sole sugarcane in 2015/16 and 2016/17 seasons, respectively, compared to sole sugarcane and without weed control.From this investigate cane be recommended to sowing sugarcane fields intercropping with soybean legume crop as the animal feeding and weed control by hand hoeing twice or Stomp at the rate 1.75 l/fed to overcome on weeds problems and increased sugarcane productivity as well as increased gross income by productivity the second crops (soybean as a forage crop).

“…The quality of food for phytophages is often positively affected by the increased concentration of organic nitrogen in leaves and phloem of plants (Rhoades 1979, White 1984, Mattson & Haack 1987, Haddad et al 2000. On the other hand, depending on species and conditions nitrogen fertiliser does not have only positive effects on insects (Bi et al 2005, Pikul et al 2005, but negative (Salmah et al 1998, Pitan et al 2000 or even no effects at all (Haile & Hofsvang 2001, Srikanth et al 2002. Sucking insects have shown a much stronger response to the level of nitrogen (fertiliser) than chewing insects (Annan et al 1997, Megahed 2005, Schulz et al 2008, Butler et al 2012.…”

Birches, Betula pendula Roth, grown in pots were fertilized with ammonium nitrate (NH4 NO3) in the amounts of 0 g, 0.5 g, 1 g and 1.5 g per plant four times per season on moist soil surface with subsequent gradual dissolution by watering. Cabera pusaria caterpillars from laboratory w ere fed on leaves with different content of nitrogen (19.2 - 47.4 mg×g-1 ). The excessive content of nitrogen in food appeared to be a stress factor as it increased mortality and development time of the caterpillars, decreased food consumption and weight of larvae and pupae, and caused anomalies at pupation. This is as expected for a summer-feeding caterpillar feeding on foliage with seasonally decreasing concentration of nitrogen.
