The field trials were conducted in 2017–2019 in the laboratory for cultivation technologies of row crops in the FSBSI “Agricultural Research Center “Donskoy”. The experimental plots were located in the southern soil-climatic zone of the Rostov region characterized with insufficient and unstable moisture. The soil of the experimental plots was heavy-loamy ordinary blackearth (chernozem) on forestry loams with 3.2% of humus, fertilized with 18.5 – 20.0 mg/kg of P2O5 and 342 – 360 mg/kg of K2O. The current paper has presented the study results of the effect of herbicides on middle ripening maize hybrid “Zernogradsky 354 MV”, included in the State List of RF in 2010. The used herbicides had a positive effect on reducing the contamination of maize sowings with monocotyledonous and dicotyledonous weeds (90% decrease), which contributed to an improvement of grain crop productivity. In the phase of full ripeness, the number of weeds in the experimental variants was 2.7–3.1 times less than in the control variant. The productivity increase in the control variant was 0.55–0.83 t/ha. The largest net income (22 545 rub/ha) was obtained due to the use of the herbicide “Elumis”. The high cost of the preparations negatively affected the cost of production, which exceeded the control variant on 436–519 rubles per ton. The profitability of the applied herbicides was lower than the control variant on 30 and 39%. The grain productivity increase obtained in the trials has paid for the costs of herbicides’ use; the payback amount was 1.15–1.57 rubles.

Recognition of high yielding and nitrogen (N) fixing groundnut genotypes and desegregating them in the cereal-based cropping systems common in savannah regions will enhance food security and reduce the need for high N fertilizers hence, minimize the high cost and associated environmental consequences. Field trials were conducted during the 2015 growing season at the Research Farms of Bayero University Kano (BUK) and Institute for Agricultural Research (IAR), Ahmadu Bello University, Samaru-Zaria to assess the yield potential and Biolog- ical N fixation in 15 groundnut genotypes (ICG 4729, ICGV-IS 07823, ICGV-IS 07893, ICGV-IS 07908, ICGV- SM 07539, ICGV- SM 07599, ICGV-IS 09926, ICGV-IS 09932, ICGV-IS 09992, ICGV-IS 09994, SAMNUT-21, SAMNUT-22, SAMNUT-25, KAMPALA and KWANKWAS). The groundnut genotypes and reference Maize crop (SAMMAZ 29) were planted in a randomized complete block design in three replications. N difference method was used to estimate the amount of N fixed. The parameters determined were the number of nodules, nod- ule dry weight, shoot and root dry weights, pod, and haulm yield as well as N fixation. The nodule dry weight, BNF, haulm, and pod yield were statistically significant (P<0.01) concerning genotype and location. Similarly, their interac- tion effect was also highly significant. ICGV-IS 09926 recorded the highest nod- ule dry weight of 2.07mg /plant across the locations while ICGV-IS 09932 had the highest BNF value of 140.27Kg/ha. Additionally, KAMPALA had the high- est haulm yield, while ICGV-IS 07893 had the highest pod yield across the loca- tions with a significant interaction effect. The result shows that ICGV-IS 07893 and ICGV-IS 09932, as well as ICGV-IS 09994 and SAMNUT – 22, were the best genotypes concerning BNF, haulm and pod yield in the Northern Guinea and Sudan Savannahs of Nigeria respectively with the potential for a corresponding beneficial effect.

The cotton plant (Gossypium spp.) is sensitive to numerous environmental factors. This study was aimed at predicting effects of climatic factors grouped into convenient intervals (in days) on cotton flower and boll production compared with daily observations. Two uniformity field trials using the cotton (G. barbadense L.) cv. Giza 75 were conducted in 1992 and 1993 at the Agricultural Research Center, Giza, Egypt. Randomly chosen plants were used to record daily numbers of flowers and bolls during the reproductive stage (60 days). During this period, daily air temperature, temperature magnitude, evaporation, surface soil temperature, sunshine duration, humidity, and wind speed were recorded. Data, grouped into intervals of 2, 3, 4, 5, 6, and 10 d, were correlated with cotton production variables using regression analysis. Evaporation was found to be the most important climatic variable affecting flower and boll production, followed by humidity and sunshine duration. The least important variables were surface soil temperature at 0600 and minimum air temperature. The 5-d interval was found to provide the best correlation with yield parameters. Applying appropriate cultural practices that minimize the deleterious effects of evaporation and humidity could lead to an important improvement in cotton yield in Egypt. Key words: Cotton, flower production, boll production, boll retention
