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.

Hybrid Maize

Maize (Zea mays L.) is one of the most versatile crop grown throughout the tropical as well as temperate regions of the world. On the other hand, the lathyrus or grass pea or chickling pea is also called ‘khesari’ and is a very hardy crop that thrives well under adverse climatic conditions. It can fix biological nitrogen in their roots through symbiotic relationship with Rhizobium leguminoseram. The field experiment was conducted on seed priming of hybrid maize and lathyrus at Central Research Farm, BCKV, Nadia under new alluvial zone of West Bengal, India in Randomized Complete Block Design (RCBD) with 3 replications during kharif season of 2016 and 2017 and rabi season of 2016-17 and 2017-18. Experimental results reveal that seed priming methods significantly influenced the germination, growth parameters, yield attributes and yield of hybrid maize-lathyrus grown in sequence under rainfed situation. Seed priming with ZnSO4 @ 0.5% for 12 hours recorded the highest number of grains per cob (319.9) and highest plant height (262.10 cm) at harvest of hybrid maize. Grain yield and stover yield of hybrid maize showed positive and highly significant (P = 0.01) with each other (r = 0.945). The maximum number of pods per plant (50.28) was observed in seed priming with ZnSO4 @ 0.5% for 12 hours and was statistically at par with seed priming with KNO3 @ 0.5% for 12 hours (48.33) in case of lathyrus. Number of pods/ plants showed positive and highly significant (P = 0.01) correlation with grain yield (r = 0.986) of lathyrus. On the basis of pooled values of 2 years of experimentation, seed priming with ZnSO4 @ 0.5% for 12 hours could be recommended due to higher yield (7.94 t ha-1 of kharif hybrid maize and 1682 kg ha-1 of lathyrus) and higher net return (Rs.69,904/-ha-1 for maize, Rs.40,327/- ha-1 for lathyrus) as well as highest B:C ratio (2.74 of kharif hybrid maize and 2.94 of lathyrus) for maize-lathyrus in sequence under rainfed situation.

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
