Agriculture in a water-limited environment is critically important for today and for the future. This research evaluates the impact of deficit irrigation in different planting methods on the physio-morphological traits, grain yield and WUE of maize (Zea mays L.). The experiment was carried out in 2015 and 2016, consisting of three planting methods (i.e., BBF, SNF, and DWF) and four irrigation levels (i.e., I10D: irrigation once in ten days, I40: irrigation at 40% DASM, I50: irrigation at 50% DASM, and I60: irrigation at 60% DASM). The results reveal that varying degrees of water stress due to planting methods and irrigation levels greatly influenced the maize physio-morphological traits and yield attributes. The combined effect of DWF + I50 benefited the maize in terms of higher leaf area, RWC, SPAD values, CGR, and LAD, followed by the SNF method at 60 DAS. As a result, DWF + I50 and SNF + I50 had higher 100 grain weight (30.5 to 31.8 g), cob weight (181.4 to 189.6 g cob−1) and grain yield (35.3% to 36.4%) compared to other treatments. However, the reduction in the number of irrigations (24.0%) under SNF + I50 resulted in a 34% water saving. Thus, under a water-limited situation in semi-arid tropics, the practice of the SNF method + I50 could be an alternative way to explore the physio-morphological benefits in maize.

A short-term field and laboratory experiment was conducted to assess the impact of four traditional tillage methods on the physical, chemical and biochemical properties of a sandy clay loam alfisol under maize (Zea mays L.) cultivation following a fallow period of five years. Treatments included slash only (SO), slash +burn (SB), slash+ ridge (SR) and herbicide (glyphosate) application (HA) at the recommended rate of 2 L/ha-1. Results from the statistical analysis of data from this study showed inconsistent trends of tillage treatments on soil physical properties. However, slash +burn (SB) tillage significantly (p < 0.05) enhanced chemical properties such as the soil pH, available P, exchangeable K+, Ca2+, and Mg2+ compared to their respective values before treatment application in the two years under study. Amongst the treatments, slash + burn (SB) tillage further exerted the most significant (P ≤ 0.05) effect on urease, L-asparaginase, L-glutaminase, dehydrogenase, acid and alkaline phosphatase activities, but recorded the least values for amidase and β-glucosidase activities in soil. Results from this study therefore, suggest that SB tillage treatment was beneficial to the soil environment as it has proven to be more promising and effective for enhancing the selected soil quality indicators on the soil type due to quick mineralization and release of bound nutrients present in the soil and litter.

Corn Grain Yield

The objective of this study was to determine the effects on grain yield of growing cultivars in mixtures of different proportions. Two maize (Zea mays L.) hybrids, Pride 116 and United 106, were grown for 2 yr in pure stand and in seven mixtures of different proportions (7:1, 6:2, 5:3, 4:4, 3:5, 2:6, 1:7) at plant densities of 61 500, 99 400, and 136 000 plants per hectare. The total number of mixture combinations was 42, i.e. 2 years × three densities × seven proportions. All but one mixture yielded as expected based on the yield of component hybrids in pure stand. The higher yielding hybrid (United 106) yielded significantly less grain per plant in mixtures than in pure stand. The lower yielding hybrid (Pride 116) yielded more in mixtures than in pure stand, although the difference was not significant. These data support previous observations that the ability of a hybrid to yield in pure stands is not necessarily related to its ability to yield in mixtures. High plant densities appear to enhance the likelihood of interactions occurring among hybrids. For United 106, the number of proportions yielding less grain per plant than in pure stand was highly significant at the two higher plant densities. For Pride 116, the number of proportions yielding more than in pure stand was highly significant at the highest plant density.Key words: Corn, grain yield, mixtures of different proportions, high plant densities, Zea mays
