Yield and profitability of groundnut (Arachis hypogaea L.) as influenced by sowing dates and nutrient levels with different varieties

Abstract

A field study was conducted to evaluate the date of sowing of groundnut (<italic>Arachis hypogaea</italic> L.) during <italic>kharif</italic> 2009 and 2010. Experiment was laid out in split-plot design by assigned dates of sowing (20 April, 15 May, 9 June and 4 July) and varieties (‘HNG 10’ and ‘TG 37A’ ) in main plots and four fertility levels (without fertilizers, 20 N + 40 P<sub>2</sub>O<sub>5</sub>, 30 N + 60 P<sub>2</sub>O<sub>5</sub> and 40 N + 80 P<sub>2</sub>O<sub>5</sub> kg /ha) in sub-plots. Yield components of semi-spreading variety ‘HNG 10’ were statistically at par with each other at different dates of sowing from 20 April to 9 June. Harvest index in both the varieties was observed significantly higher in 4 July sowing. The results of the study showed that significantly higher crop stand at harvest was observed in 9 June and 4 July sowing than all other sowing dates and variety ‘TG 37A’ flowered significantly earlier than ‘HNG10’. Significantly higher yields were recorded in 30 kg N+60 kg P<sub>2</sub>O<sub>5</sub> /ha which was statistically at par with 40 kg N+80 kg P<sub>2</sub>O<sub>5</sub> /ha. On the basis of economics, variety ‘HNG 10’ of groundnut recorded significantly higher net re urn ( 61843/ha) when sown on 9 June.

Studies on site specific nutrient management (SSNM) on growth and yield of groundnut (Arachis hypogaea) under irrigation in southern Karnatak

“…Even after the flowering also try to accumulate as much as photosynthates into the sink thus delaying the days to maturity. The results are in line with findings of Thavaprakash (2000) and Meena, and Yadav, (2015).…”

Influence of dates of sowing and irrigation scheduling on phenology, growth and yield dynamics of fenugreek (trigonella foenum greacum l.)

“…Relative water content of fenugreek leaves was recorded periodically at different growth stages (seedling, branching, flowering, pod formation and pod development respectively) of fenugreek in different date of sowing. During seedling, branching stage the maximum relative water content was Yadav (2015) found significantly higher crop stand at harvest for the later sown crops among all sowing dates. (Fig.5).…”

Influence of improved agronomical practices on yield and economics of chickpea (Cicer arietinum L.)in gird zone of Madhya Pradesh on farmers field

“…Similarly improved variety enhanced the yield by 25.41% over farm saved seed. Meena and Yadav (2015) was also reported that the high yielding varieties helps in increasing the productivity of major field crops.Optimum nutrition 36.20% over farmers practices. Nawale et al(2009) who obtained that the optimum dose of fertilizers increased the yield of chickpea by 34.7% as compared to farmers practices.Weed management enhance the yield of chickpea by 41.24% over farmers practices, Pandit et al (2017) and Mishra (1997).…”

“…The varieties cultivated by the farmers which are low yielding and susceptible to pests and disease. The high yielding varieties helps increasing the productivity Yadav, 2015.). Hence, on farm trail were conducted on chickpea in Grid zone of M.P., to find out the effect of improved practices evolved by research over farmers practices.…”
