Grass intercropping under no-till is an option to increase crop residues on the soil surface and diversity. Urochloa spp. frequently selected for improve land use agricultural production because of its high residue production, slow decomposition, as well vigorous, abundant, deep root system. However, effects maize, especially residues, subsequent crops in rotation have not been established. To ...

Abstract In the tropics, smallholder farming characterizes some of world's most biodiverse landscapes. Agroecology as a pathway to sustainable agriculture has been proposed and implemented in sub‐Saharan Africa, but effects agricultural practices on biodiversity ecosystem services are understudied. Similarly, contribution different landscape elements, such shrubland or grassland cover, fields r...

With approximately 11 million habitants, Guatemala is mostly a rural country, with 60 percent of the population living on farms and 50 percent of the population indigenous. Maize and beans are the main staple food in most households, with a per capita consumption of 9.4 kg per year. Since few other sources of protein are available, this amount is not sufficient to ensure an acceptable nutrition...

Pyruvate orthophosphate dikinase (PPDK) was found in various immature seeds of C(3) plants (wheat, pea, green bean, plum, and castor bean), in some C(3) leaves (tobacco, spinach, sunflower, and wheat), and in C(4) (maize) kernels. The enzyme in the C(3) plants cross-reacts with rabbit antiserum against maize PPDK. Based on protein blot analysis, the apparent subunit size of PPDK from wheat seed...

UDPGDH (UDP-D-glucose dehydrogenase) oxidizes UDP-Glc (UDP-D-glucose) to UDP-GlcA (UDP-D-glucuronate), the precursor of UDP-D-xylose and UDP-L-arabinose, major cell wall polysaccharide precursors. Maize (Zea mays L.) has at least two putative UDPGDH genes (A and B), according to sequence similarity to a soya bean UDPGDH gene. The predicted maize amino acid sequences have 95% similarity to that ...

Studies at the University of Reading (UK) compared silage quality, feed intake and digestibility of maize silage with maize±sun ̄ower (MS), maize±kale (MK) and maize±runner bean (MRB) silage, when sun ̄owers, kale and runner beans represented 26, 7 and 16% of total silage dry matter (DM). All intercrop silages had higher crude protein values (MS, 137 g kgÿ1, MRB, 120 g kgÿ1, MK, 105 g kgÿ1) than ...

Examination of closely related species pairs is suggested for evolutionary comparisons of different degrees of polyphagy, which we did here with three taxa of lepidopteran herbivores, Spodoptera spp (S. littoralis, S. frugiperda maize (C) and rice (R) strains) for a RNAseq analysis of the midguts from the 3rd instar insect larvae for differential metabolic responses after feeding on pinto bean ...

Abstract Aim Intercropping often leads to improved productivity of individual species compared monocultures. We have practically little knowledge facilitation effects in different intercropping systems and their importance creating soil legacies that can indirectly affect the succeeding crop a rotation through plant-soil feedback (PSF) effects. Methods To test this, we used two-phased field exp...
