Yield performance of groundnut (Arachis hypogaea L.) genotypes under varying plant densities and seasons

Abstract

The experiment was conducted at the Education and Research Farm of the Department of Botany, College of Agriculture, Dapoli, Dist. Ratnagiri, Maharashtra state during the period from Kharif and Rabbi 2017-18 and 2018-19 to study the yield performance of groundnut genotypes under varying plant densities and seasons. The experiment was laid out in a split plot design with three replications. Results showed that different treatments had significant influence on growth and yield contributing characters. Crop sown in Rabbi season (S2) exhibited better achievement than kharif season with respect to all yield and yield component. The genotype G3 (RTNG-27) performed best in yield contributing characters than other genotypes. The important findings emerged from this investigation revealed that groundnut sown at the spacing 30 × 20 cm recorded significantly highest number of pods per plant (25.13 plant-1), pod weight per plant (3.12 plant-1), shelling percentage (70.07 plant-1) and harvest index (40.84 plant-1) was comparable with spacing 30 ×15 cm and 30 × 10 cm. Closer spacing of 30 x 10 cm is the best spacing in terms of pod yield q/ha (38.09 q/ha) in groundnut genotypes.

Effect of Different Cultural Treatments on Branching and Yield of Groundnut (Arachis hypogea L.)

“…According to the observations taken during the systematic conduction of the experiment with good maintenance of the experimental plots, we have concluded that as the branching of groundnut increases, the yield also increases, respectively. However, the extent of increase in yield and branching varies for different treatments and those differences in the yield obtained were given below: The number of branches led to an increase in yield based on different types of treatments in different experiments were reported in findings of Shashidhar VR, et al [3], Gowthami V, et al [4], Nigam SN, et al [5], Ali FM, et al [6], Avinasha BL, et al [7], Nagar R, et al [8], Oppong SD, et al [9], Thilini SPLNK, et al [10], Gawas D, et al [11], Magagula N, et al [12], Sathiya K, et al [13], Mohanty P, et al [14], Ibrahim II, et al [15], Yilmaz M, et al [16], Iddrisu A, et al [17], Singh N, et al [18], El Naim AM, et al [19], Seijo G, et al [20], Maleki SJ, et al [21], Michael CY, et al [22], Sanders TH, et al [23,24], Veeramani P, et al [25].…”

Assessing Groundnut (Arachis hypogaea L.) Genotype Yields and Yield Traits with Different Planting Geometries on Broad Bed and Furrows

“…Groundnut kernels contain 40-50% oil, widely used in cooking and is rich in vitamins A, B and E. It is also valued as a rotation crop and as a legume, it aids in nitrogen fixation and improves soil health. Globally, groundnut is cultivated in over 100 countries on 29.5 million hectares, producing 48.7 million metric tonnes with an average yield of 1.6 metric tonnes ha -1 [1]. Developing countries contribute significantly, accounting for 97% of the cultivation area and 94% of the production.…”
