A minimum cycle basis of a weighted undirected graph G is a basis of the cycle space of G such that the total weight of the cycles in this basis is minimized. If G is a planar graph with non-negative edge weights, such a basis can be found in O(n2) time and space, where n is the size of G. We show that this is optimal if an explicit representation of the basis is required. We then present an O(...

The aim of this study was to determine the effect composting on height increase Jengkol (Pithecolobium jiringa) puppies after three months weaning at Samarinda State Agricultural Polytechnic Nursery.
 This used a completely randomized design, with 4 types treatment media and 10 replications. treatments were N0 (pure sub soil), N1 (75% soil + 25% compost), N2 (50% 50% compost) N3 (25% 75% c...

the performance of new forage brassica plants were studied in ilam, iran, during 2012-2014 in a field experiment using a randomized complete block design with four replications. the treatments included, different forage crops perko, buko, oilseed radish, berseem clover, and the combination of three plants ramtil, phaselia, and clover. the studied traits consisted of plant height, forage yield, ...

to evaluate of quantitative and qualitative yield of two basil (ocimum basilicum l.) medicinal plants as affected by planting pattern and plant density, an experiment carried out in factorial arrangement basis on randomized complete block design with three replications. two varieties (green and purple) of basil, two planting patterns (single and double row) and four plant densities (40, 60, 80 ...

Selenium (Se) biofortification has been practiced in Se-deficient regions throughout the world primarily by adding inorganic sources of Se to the soil. Considering the use of adding organic sources of Se could be useful as an alternative Se amendment for the production of Se-biofortified food crops. In this multi-year micro-plot study, we investigate growing carrots and broccoli in soils that h...

Cassava is a perennial crop that can adapt to periods of drought at different times in growing season, which permits scheduling planting and harvest develop production systems supplying roots continuously. However, farmers plant cassava the onset rains creates glut results unattractive root prices. Thus, need understand how varieties respond dates ages be able use opportunities income generatio...
