“…Poor translocation of metabolites to the reproductive stage may be one of the reasons for lower yield in control or unprimed crop. Similar results were also reported by Ali et al (2013) in wheat, Mohammad Mazid (2014) in chickpea and Kalpana et al (2015) in wheat.…”

A split plot design field study was conducted during summer month of 2012 and 2013 at the vegetable block of Indian Institute of Horticultural Research in Bangalore, India to evaluate if priming could improve grain yield and water use efficiency of cowpea under limited water supply condition through drip system. Seeds of cultivar Arka garima received the following priming treatments: they were soaked in GA 3 ,Calcium Chloride, Ammonium Molybdate, Potassium Bromide, Magnesium Nitrate, Zinc Sulphate solutions, and aerated distil water (hydropriming) for 24 hours at 15 o C. Crops were subjected to three irrigation intervals in which the irrigation was applied at 0.9, 0.7, 0.5 Epan Replenishment of evaporation. Seed priming treatments reduced the mean emergence time, promoted germination, early canopy development and flower initiation in comparison to the untreated control. Plant height, number of branches, total dry matter accumulation, number of pods per plant, number of seeds per pod, 1000 seed weight and grain and biological yield, harvest index and irrigation water use efficiency increased by different priming treatments. Seed priming increased the irrigation water use efficiency (IWUE) of all irrigation regimes. Grain yields linearly increased at 0.9 Epan Replenishment while maximum IWUE was achieved at 0.5 Epan Replenishment. Results suggest that the use of seed priming with either GA 3 (100ppm) or Ammonium Molybdate (10 -3 M) for 24 hours at low concentration can be helpful in cowpea under both optimum as well as limited water conditions.

“…Nutripriming is now recently focused by using macro or micronutrient enriched seeds in rice (Hafeez Ur Rehman et al, 2015). Seed priming with KNO 3 and water improved biological and grain yield of rapeseed through enhancing rate and percentage of seedling establishment (Ali et al, 2013). Pre-sowing hardening treatment of cowpea seeds in IAA and GA 3 significantly enhanced germination and seedling growth and also withstood adverse effect of water stress (Audi and Mukhta, 2009).…”

A field study was conducted during summer season of 2012 and 2013 at Indian Institute of Horticultural Research in Bangalore, India to evaluate if priming could improve grain yield and water use efficiency of cowpea under limited water supply condition through drip system. Seed variety Arka Garima received the following priming treatments: they were soaked in GA 3 ,CaCl 2 , ammonium molybdate, KBr, MgNO 3 , ZnSO 4 solutions and water (hydropriming) for 24 hours at 15 o C. Crop was subjected to three irrigation intervals in which the irrigation was applied at 0.9, 0.7, 0.5 Epan Replenishment of evaporation. Plant height, number of trifoliate leaves, total dry matter accumulation, number of pods per plant, number of seeds per pod, 1000 seed weight and grain and biological yield were increased by different priming treatments compared to control. Seed priming increased the LAI, RGR, CGR and NAR at all irrigation regimes. Results suggest that the use of seed priming with either GA 3 (100ppm) or ammonium molybdate (10 -3 M) for 24 hours at low concentration can be helpful in cowpea under both optimum as well as limited water conditions.

“…Paradoxically, growers growing C3 and C4 cereals adopt conventional practices instead of approved practices that make more efficient use of resources [43][44][45][46][47][48][49][50]. Nitrogen is the key constituent of agricultural inputs to maintain production of these cereals throughout their lifecycle [51][52][53][54] (Figure 3). Surplus N and/or N applied without splitting can be lost through pathways such as nitrification and volatilization [8,40,41] (Figure 1).…”

Abstract:Resources are limited, thus improving resource use efficiency is a key objective for cereal-based cropping systems. This field study was carried out to quantify resource use efficiencies in selected C 3 and C 4 cereals under split nitrogen (N) application regimes. The study included the following treatments: six cereals (three C 3 : wheat, oat, and barley; and three C 4 : maize, millet, and sorghum) and four split N application regimes (NS 1 = full amount of N at sowing; NS 2 = half N at sowing + half N at first irrigation; NS 3 = Results revealed that C 4 cereals out-yielded C 3 cereals in terms of biomass production, grain yield, and resource use efficiencies (i.e., radiation use efficiency (RUE) and nitrogen use efficiency (NUE)), while splitting N into three applications proved to be a better strategy for all of the selected winter and summer cereals. The results suggest that C 4 cereals should be added into existing cereal-based cropping systems and N application done in three installments to boost productivity and higher resource use efficiency to ensure food security for the burgeoning population.
