Book Description
The present study is the research work of my M.Sc. which titled "optimizing row spacing in different wheat cultivars" was conducted at Agronomic Research Farm, Department of Agronomy, Faculty of Agricultural sciences and technologies, Bahauddin Zakariya University, Multan. Three row spacings viz. 10, 20 and 30 cm and five wheat genotypes viz. Sehar-2006, FS-2008, Lasani-2008, AS-2002 and TD-I were included in the study. The experiment was laid out in randomized complete block design (RCBD) with split plot arrangements having net plot size of 5 m x 1.8 m and replicated three times. Row spacings were kept in main plots while wheat genotypes were kept in sub plots.

Book Description
Four winter wheat cultivars, Bezostaya, Maris-Hobbit, Roussalka and Stephens, selected on the basis of the diversity of their pedigree and phenotype, were planted at Hyslop Experiment Station near Corvallis in Western Oregon to study their performance at three different row spacings (10, 16 and 24 cm), three seeding rates (100, 160, and 240 Kg/ha) and at two seeding dates (October 13 and November 12). A similar experiment was conducted at the Sherman Experiment Station, Moro in Eastern Oregon, using only two winter wheat cultivars, Stephens and Jackmar. Data were obtained on grain yield, tillers and spikes per square meter, heading and anthesis date, plant height, kernels per spike, 1000 kernel weight, test weight and harvest index. At Hyslop Experiment Station, Stephens, Bezostaya and Roussalka produced maximum grain yield at 10 cm row spacing and 160 Kg/ha seeding rate, and Maris-Hobbit at 24 cm row spacing and 160 Kg/ha seeding rate. At Sherman Experiment Station, 30 cm row spacing and 90 Kg/ha seeding rate constitutes the best combination for Stephens, and 30 cm row spacing and 120 Kg/ha seeding rate for the club wheat Jackmar. The interaction between row spacings x cultivars and seeding rates x cultivars indicated that all the cultivars produced high numbers of tillers and spikes per m2 at narrow (10 cm) row spacing and high (240 Kg/ha) seeding rate. There were no significant differences between row spacings for heading and anthesis date. Lower seeding rate resulted in later heading date. The cultivar Roussalka was the earliest and Maris-Hobbit the latest in average heading date, Plant height decreased with increased row spacing and increased with increased seeding rate. The plants of the four cultivars were shorter at the second date than at the first. More kernels per spike were produced at the second than at the first date. An increase in seeding rates was accompanied by a decrease in the number of kernels per spike. There were no significant differences between the three row spacings, the three seeding rates and the four cultivars for test weight. The different row spacings and seeding rates did not affect the TOGO kernel weight. Considering the cultivars, Stephens produced a higher 1000 kernel weight at the two seeding dates than Maris- Hobbit, Bezostaya and Roussalka.

Book Description
This textbook focuses specifically on the combined topics of irrigation and drainage engineering. It emphasizes both basic concepts and practical applications of the latest technologies available. The design of irrigation, pumping, and drainage systems using Excel and Visual Basic for Applications programs are explained for both graduate and undergraduate students and practicing engineers. The book emphasizes environmental protection, economics, and engineering design processes. It includes detailed chapters on irrigation economics, soils, reference evapotranspiration, crop evapotranspiration, pipe flow, pumps, open-channel flow, groundwater, center pivots, turf and landscape, drip, orchards, wheel lines, hand lines, surfaces, greenhouse hydroponics, soil water movement, drainage systems design, drainage and wetlands contaminant fate and transport. It contains summaries, homework problems, and color photos. The book draws from the fields of fluid mechanics, soil physics, hydrology, soil chemistry, economics, and plant sciences to present a broad interdisciplinary view of the fundamental concepts in irrigation and drainage systems design.

Book Description
With the objective of clarify the effect of row spacing and plant density over the yield of irrigated wheat a experiment were conducted at the Cerrado Research Center (CPAC) experimental field. The trial was planted in May and harvested in September, 1985. The experimental design was a split plot in a complete randomized blocks with 4 replications where plant density were the main plot and row-spacing the sub-plot. The treatments were composed by the combination of the three plant density (200, 300 and 400 viable seed per m2) and by three row spacing (0.17 x 0. 17 cm, 0.17 x 0.34 cm and 0.34cm in between rows). The cultivar used was BR 12-Aruana and the equipment of irrigation utilized was the Central Pivot. The experiment was instaled in dark red latosol and the fertilization was at rate of 20, 100 and 60kg/ha of N, P and K applied at sowing time plus 60 Kg/ha of N as a side dressing. No interaction were found between plant density and row-spacing. The effect of row spacing and plant density were shown on tables 1 and 2 respectively. The row-spacing effect were not significant over the hectoleter weight, thousand Kernel weight, number of Kernel/spike and plant height. The row-spacing 0.17 x 0.17 increased significantly the yield per area the number of spikes per m2, the number of tiller per plant, the number of heads per plant and number of tiller per m2. The plant densities were not significant over the yield/area, hectoliter weight, thousand Kernel weight, number of heads/m2, plant height and tillers number/m2. The plant density of 200 viable seeds/m2 had a positive effect over the Kernels/spike, tillers/plant, heads/plant and over tillers surviving %. The overall yield mean of the experiment was 5.584 kg/ha. This was the year of a 3 years experiment at differents spots of Cerrado Region. The number of cultivars will increased and shanged as needed.
