Response of fenugreek (Trigonella foenum-graecum) to bio-regulators TGA and N-acetyl cystein under drip irrigation levels

Abstract

Field experiments were conducted during winter seasons of 2010-11 and 2011-12 at Bikaner (Rajasthan) to study the effect of bioregulators viz., TGA and N-acetyl cystein under different drip irrigation levels on yield, yield attributes, water use and water use efficiency of fenugreek. The highest plant height (69 cm) and yield attributes viz., branches plant -1 (7.6), pods plant -1 (46.3), pod length (13.5 cm), seed pod -1 (16) and test weight (12.7 g) were recorded with 100% ETc + TGA (200 ppm). Further, 80% ETc + TGA (200 ppm), and 100% ETc + N-acetyl cystein (both 10 and 20 ppm) and 100% ETc + TGA (both 100 and 200 ppm) produced comparable plant height. However, 80% ETc + N-acetyl cystein (both 10 and 20 ppm), 80% ETc + TGA (both 100 and 200 ppm), 100% ETc + N-acetyl cystein (both 10 and 20 ppm), 100% ETc + TGA (100 ppm) and 100% ETc + TGA (200 ppm) recorded at par branches plant -1 , pods plant -1 , pod length and test weight of fenugreek. Highest seed and biological yield of fenugreek were recorded with 100% ETc + Nacetyl cystein (20 ppm), which was at par with 100% ETc + N-acetyl cystein (10 ppm) and 100% ETc + TGA (both 100 and 200 ppm). Maximum water use recorded at 100% ETc with or without bioregulators, whereas maximum water use efficiency was recorded with 60% ETc + N-acetyl cystein (20 ppm) followed by 60% ETc + N-acetyl cystein (10 ppm).

Growth and yield of Kasuri Methi (Trigonella corniculata L.) var. Pusa Kasuri as influenced by different organic manures and biofertilizers under Telangana conditions

“…The highest plant spread (North -South) and (East -West) at 30, 60, 90 days after sowing and harvest stage was recorded in T10 -50% RDN through FYM (8 t ha -1 ) + 50% RDN through Neem cake (1 t ha -1 ) + 50% RDN through Vermicompost (2 t ha -1 ) + AMC (7.5 lit ha -1 ) might be due to the same treatment registered maximum plant height and more number of branches per plant as compared to rest of the treatments. The results are similar with the findings of Khiriya et al (2001) [5] , Aiyanathan and Salairajan (2008) [1] in fenugreek and Naveen (2010) [9] in kasuri methi.…”

Identifying SNP markers associated with distinctness, uniformity, and stability testing in Egyptian fenugreek genotypes

“…Several studies on other plants illustrated that the maternal habitat [ 43 – 46 ] and seed priming [ 47 – 49 ] influence offspring adaptive plasticity to tolerate abiotic stresses. Furthermore, previous research on fenugreek reported its ability to withstand a wide range of sodicity at various growth stages [ 50 – 53 ]. Altogether, they illustrate the power of our population to grow in the newly reclaimed saline sandy soil irrigated with saline water in Wadi, as most of the genotypes were collected from Upper Egypt, Alexandria, Faiyum, and Ismailia governorates with sandy soil of different degrees of salinity.…”

Studies on irrigation regimes and fertility levels for kalonji (Nigella sativa L.) under South-Eastern Rajasthan

“…The irrigation water use efficiency depends on irrigation level. Irrigation scheduling provides water to the plants, which matches the crop evapotranspiration rate and provides optimum irrigation at critical growth stages, resulting in high water use efficiency (Mehta et al, 2010). This increase in water saving might be due to the efficient use of water, which was applied to maintain the appropriate soil moisture along with the maximum yield obtained with the minimum quantity of water.…”

“…However, it was found at par with application of 100 % RDF (38.3 kg ha-mm -1 ) and (3.83 kg m -3 ) of kalonji. The higher water use efficiency and water productivity with higher level of fertilizer might be due to a greater increase in seed production (Mehta et al, 2010). Under lower fertilizer levels obtained lower water use efficiency and water productivity due to low availability of nutrients, which resulted in higher water use but minimum economic yield.…”
