“…Intercropping of millet (Bdliya and Muhammad 2006) and that of maize (Ihejirika 2007) in Nigeria and of pearl millet in India (Srinivas et al 2002) with peanut show significantly lower ELS/LLS severity on peanut in comparison with sole peanut crop without adversely affecting the yield of inter crops. NPK fertilizer rates and peanut plant population per hectare significantly influence the severity of ELS, the least severity of the ELS being at the density of 250,000 peanut plants/ha in compari son to 1,000,000 plants/ha (Ihejirika et al 2006a). Among several methods of irrigation studied Johnson 2007, Woodward et al 2008), subsurface drip irrigation is useful in avoiding the increase and spread of the ELS compared with overhead sprinkler irrigation (Lanier et al 2004).…”

AgriculturalSciences. He has more than 22 years of research experience in oilseed crop disease management and has significantly contributed in the areas of understanding the host-pathogen interactions, epi demiology, and integrated disease management in sunflower, safflower, sesame, peanut, and rape seed-mustard crops. He has published more than 70 peer-reviewed research papers and 4 books. Dr. Chattopadhyay has to his credit several academic awards and one patent. His significant research achievements include the development of Fusarium wilt-resistant genotypes in safflower, the iden tification of genotypes of Brassica juncea resistant to a mixture of isolates of Albugo candida, the development of a biocontrol agent formulation to reduce the use of fungicides in the management of major diseases of oilseeds (Brassica), and seed treatment (and foliar application) of aqueous bulb extract of Allium sativum for the management of major foliar diseases (Alternaria blight, white rust, powdery mildew, and Sclerotinia stem rot) of mustard.

“…Akibatnya populasi hama pengisap seperti kutudaun, wereng, dan trips menurun (Jima et al 2013, Kalaichelvi 2008). Ihrejrika et al (2006) menyatakan bahwa populasi tanaman yang rapat akan meningkatkan serangan penyakit. Hal ini juga terjadi pada perlakuan konvensional, dimana intensitas serangan penyakit layu bakteri lebih tinggi daripada serangannya pada perlakuan PHT.…”

<p>Pengembangan kentang di dataran medium dihadapkan pada kendala serangan organisme pengganggu tumbuhan (OPT) yang dapat menurunkan kualitas dan kuantitas hasil panen. Oleh karena itu diperlukan teknologi pengendalian untuk mengatasinya. Tujuan penelitian adalah untuk merakit teknologi pengendalian OPT yang dikombinasikan dengan penggunaan klon toleran suhu tinggi. Penelitian dilaksanakan di Desa Cibulakan (600 m dpl.), Kecamatan Cugenang, Kabupaten Cianjur, Jawa Barat, dari bulan Juni sampai Oktober 2012. Penelitian menggunakan rancangan acak kelompok pola faktorial dengan tiga ulangan. Macam perlakuan yang diuji adalah (A) teknologi pengendalian OPT (a1= rakitan teknologi PHT dan a2= rakitan teknologi konvensional) dan (B) klon/varietas kentang ( b1<br />= MB 17, b2= CIP 394614.117, b3= CIP 392781.1, dan b4= Granola). Hasil penelitian menunjukkan bahwa rakitan teknologi PHT mampu menekan serangan trips, tungau, kutudaun, kutukebul, dan ulat grayak hingga di bawah ambang pengendalian, kecuali penyakit layu bakteri. Dengan penerapan rakitan teknologi PHT penggunaan pestisida dapat ditekan sebesar 97–100%. Klon CIP 392781.1 lebih toleran terhadap penyakit layu bakteri dan hasil panennya lebih tinggi dibandingkan dengan klon CIP 394614.117. Selain itu kandungan bahan kering CIP 392781.1 cukup tinggi sebesar 18,22%. Klon CIP 392781.1 mempunyai harapan untuk dikembangkan lebih lanjut dengan dukungan teknologi pengendalian penyakit layu bakteri dan teknologi untuk menurunkan suhu tanah agar hasilnya optimum.</p>

Groundnut yields are relatively very low in Kenya compared to other countries due to the use of poor agronomic practices and low soil fertility, with phosphorous (P) being the most limiting factor. This study aimed at determining the effect of the rate and time of phosphorous application and planting densities on yield and net benefit of groundnut production. The study was conducted in two locations, Chuka University Horticultural Demonstration Farm and Kenya Agricultural and Livestock Organisation, Embu, Kenya between April and August 2018. The study used a 2 x 3 x 3 factorial experiment laid out in a Randomized Complete Block Design with three replications. There were three factors; P application rates (0, 30, and 60 Kg/ha), time of P application (at sowing, and 14 days after sowing), and planting densities (148,149; 213,331 and 333,334 plants per ha). Data on the number of kernels per pod, number of empty pods and yield of groundnuts were collected and net benefit determined by subtracting the cost of production from the gross product sale price per unit area. Data collected were subjected to analysis of variance using Statistical Analysis Software version 9.4. Significant means were separated using the Least Significance Difference at a 5% probability level. The results of the study showed that the rate and time of phosphorous application and planting densities had a significant effect (p < 0.05) on the yield of groundnuts. The highest kernel yield and net benefit obtained was 1,659.90 and 963.60 Kg/ha while the highest net benefit was KSh 8312 and 12403 which was obtained by applying 30 Kg/ha of P applied at sowing with a plant density of 333,334 plants per hectare at Chuka and Embu, respectively. The study showed that the use of appropriate agronomic practices can lead to sustainable groundnut production, thus ensuring food security and improved farmers’ income. The study recommends spacing of 30 x 10 cm and application of 30 Kg/ha of Phosphorous at sowing for sustainable groundnut production in the study area and within similar agroecological zones.
