This paper aimed to evaluate the productivity of corn crop for silage, beans and straw production in different rotation systems with spring/summer fall/winter green manures cultivated under agroecological management. The experiment was implemented a rural property managed an system since 2009, 2017/18 2018 crops. experimental design used randomized blocks, five repetitions. treatments consisted...

in order to study the effects of different sowing dates by some of companion crops on the weeds control, morphological traits and yield of corn sc 504, a field experiment was carried out of research field at tabriz university during 2010 growing season. treatments were arranged in a factorial experiment using randomized complete blocks design with three replicatins. factors was include four lev...

Cucurbitacins are feeding stimulants for corn rootworm used in baits to control the adults of this insect pest. Corn rootworm larvae also feed compulsively on cucurbitacins. Cucurbitacins are reported to be gibberellin antagonists that may preclude their use as seed treatments for these soil-dwelling insects. The crude extract of a bitter Hawkesbury watermelon containing cucurbitacin E-glycosid...

Nematicides are used to control a wide variety of nematodes on many crops; unfortunately, oftentimes the control they provide is erratic. This erratic behavior is not always predictable and has been associated with chemical, physical, and biological degradation of nematicides. Their accelerated degradation is an agricultural problem that has been observed in crop monocultures and in other crop ...

this experiment was conducted to study of using different level and treatments of common vetch (visia sativa) on broiler performance in a completely randomized design with 10 treatments, 4 replications and 10 chicks in each, using 400 cobb500 broiler chicks. treatments were: corn-soybean meal based diet as control , and unprocessed or processed common vetch seed (water or autoclaving) each at 3...

The purpose of this factorial field experiment was to investigate the influence farming systems (FS) and intercropping patterns (IPs) on physiological aspects safflower bitter vetch. Treatments included high low-input various IPs that exchanged vetch with row ratios 2:2, 2:3, 2:4, 2:5, while sole cropping (SS) (SB) were used as control. highest grain yield both plants obtained from input system...

Nematode population densities and yield of sweet corn and sweet potato as affected by the nematicide fenamiphos, in a sweet corn-sweet potato-vetch cropping system, were determined in a 5-year test (1981-85). Sweet potato was the best host of Meloidogyne incognita of these three crops. Fenamiphos 15G (6.7 kg a.i./ha) incorporated broadcast in the top 15 cm of the soil layer before planting of e...
