Assessment of the genetic diversity of groundnut ( Arachis hypogaea L.) genotypes for kernel yield, oil and fodder quantity and quality under drought conditions

The genetic assessment of 90 germplasm lines and six varieties of groundnut (Arachis hypogaea L.) were done with 13 morphological traits and 125 Simple Sequence Repeats markers. Out of 125 molecular markers, 26 were polymorphic and produced 105 alleles. The genetic diversity was found to be 52-83 per cent and Polymorphic Information Content (PIC) was 0.46-0.81 with a mean of 0.42 indicating higher magnitude of genetic diversity in the test genotypes. Analysis of molecular variance showed variation among and within individuals based on allelic variation. Principal Co-ordinate Analysis based on origin of the genotypes formed three major population groups and the genetic analysis determined by population structure divided all the germplasm lines in to 10 populations. Significant and positive correlation was observed between hundred kernel weight and hundred pod weight (r=0.769) and kernel yield (r=0.899); sound mature kernel and pod weight with kernel yield, weight of kernels and harvest index. Genotypes from distinct clusters may be selected in hybridization programme for groundnut improvement. The information on clustering of genotypes will be helpful in identification of novel and superior germplasm for hybridization and development of improved varieties.

Plot Design

A field experiment was conducted in the Experimental Research Farm of School of Agricultural Sciences and Rural Development (SASRD), Nagaland University during the kharif season 2018. Groundnut variety ICGS-76 was sown @ 70 kg ha-1 for 60×20 cm2 spacing. The experiment was laid in split plot design with three replications. The main plot treatments consisted of two lime levels: lime @ 0 t ha-1 and lime @ 3 t ha-1 while the sub- plot treatments consisted of five sulphur levels: sulphur @ (0 kg ha-1, 10 kg ha-1, 20 kg ha-1, 30 kg ha-1 and 40 kg ha-1 along with recommended dose of fertilizer at 20:60:40 kg N, P2O5 and K2O ha-1 respectively in the form of diammonium phosphate and murate of potash. The results showed that application of lime @ 3 t ha-1 gave higher growth and yield attributes compared to no lime and also application of sulphur @ 40 kg ha-1 gave higher growth and yield attributes compared to lower doses of sulphur though there was only slight increase in the attributes between each successive doses of sulphur. Overall application of lime and sulphur increased all the yield attributes of groundnut, where the highest number of pods plant-1, seeds pod-1, 100 kernels weight, pod yield, kernel yield and stover yield were recorded when treatment was done with lime @ 3 t ha1 and sulphur @ 40 kg ha-1.

Kernel Yield

The field experiment was conducted at the Eastern Region of Sri Lanka to evaluate the effects of cattle manure with EM soil application on the yield and yield components of groundnut (Arachis hypogaea L.) cv Indi. It consisted of 10 treatments replicated four times in a randomized complete block design. Treatments were five levels (0, 5, 10, 15 and 20 t/ha) of cattle manure (CM) with and without EM soil application. Air dry cattle manure was incorporated into soil two weeks before sowing and EM solution was sprayed to soil at two week intervals from flowering to maturity of the crop. All other agronomic practices were followed according to the recommendation. The results showed that the increase of cattle manure (up to 15 t/ha) combined with EM increased the number of pods, weight of pods and kernels per plant, 100-kernel weight, shelling % and total yield. Higher kernel yield (3.42 t/ha) was obtained from 15 t/ha CM + EM application. The kernel yield in the control treatment (chemical fertilizer only) was 2.78 t/ha, which was comparable to 2.81 t/ha of kernel with 15 t/ha CM application alone. This study revealed that cattle manure at the rate of 15 t/ha coupled with EM would give better yield of groundnut and it can replace chemical fertilizer use. Bangladesh J. Agril.
