Accumulation of dry matter in siliqua, number of siliqua per plant, length of siliqua and seeds per siliqua of rapeseed (Brassica campestris L.) plants were studied under three irrigation levels (no irrigation, one irrigation at 30 DAS and two irrigations at 30 and 60 DAS) and three row spacing (20 cm, 30 cm and 40 cm). Th e experiment was carried out at Sher-e-Bangla Agricultural University (S...

In order to evaluate the intercropping of barley-faba bean and choose the best planting pattern a field experiment was conducted in the growing seasons of 2015-2016 using a randomized complete block design with 8 treatments and 3 replications in Ramhormoz Khuzestan, Iran. The treatments were barley sole cropping with 20 cm spacing between rows, faba bean sole cropping with 40 cm spacing between...

Abstract: Sudoku puzzles, often seen in magazines and newspapers, are logic-based challenges where each entry within the puzzle is comprised of symbols adhering to row, column and box constraints. Previously, we had investigated their potential in frequency-hopped waveforms to achieve desirable radar ambiguity functions and compared them with random, as well as the more familiar Costas sequence...

Effective time of thinning is essential for determining a silvicultural operation schedule. One of the most commonly used methods is the percentage of radial increase to assess the effect of thinning. However, it is difficult to determine the ideal time point due to variation in tree growth rates. Event history analysis was used to quantify the optimal timings for different row thinning types f...
