“…The use of leguminous crops and shrubs has been observed as a major constituent in sustainable cropping systems, due to their biological nitrogen fixation, and therefore can be adopted in yam production [6,7]. This study proposes integrated soil nutrient management with a leguminous shrub-pigeonpea ((Cajanus cajan (L.) Millsp.))…”

Cultivation of yams by rural households contributes to food supply and income generation. Notwithstanding the importance of this crop, yam production has been stagnating, threatening rural livelihoods and food security. Contrary to traditional yam systems in Ghana, an alternative system that integrates pigeonpea and yam is being proposed to mitigate constraints in existing yam production system through replenishing soil fertility, the provision of stakes for staking, and providing nutritious grains to farmers. The purpose of this study was to explore farmers’ constraints and determine farmers’ knowledge of the pigeonpea–yam cropping system. The investigation was conducted using structured questionnaires on a sample consisting of 150 yam farmers from three major yam-producing districts of Ghana. Results revealed that access to capital, mechanization, and poor road network were among the main constraints that militated yam production. A majority (68%) farmers are also still using shifting cultivation in search of fertile lands for yam production. The study found that farmers had poor knowledge of the pigeonpea–yam cropping system and the benefits and uses of pigeonpea. Given the potential of the pigeonpea–yam intercropping system in addressing soil fertility and providing a readily available source of stakes, it would be a viable option for smallholder farmers to increase and sustain production.

“…It is important to note that judicious use of synthetic agroproducts is essential to sustainable productivity. Lack of fertilizer application in farming systems has been associated with lower yields (Ennin and Dapaah, 2008) whilst optimum fertilizer application has been reported to increase yield (Wang et al, 2012). In the present study, the combination of chemical fertilizer (NPK) and synthetic nematicide, Fulan resulted in the highest yield of yam.…”

The potential of Fulan (2,5-dimethoxytetrahydrofuran), a synthetic nematicide applied at 10 g /stand and two plant bed types; ridging and mounding to manage plant parasitic nematodes and increase the yield of yam was investigated at Ejura during 2011 and 2012 at three levels of N-P 2 0 5 -K 5 0 (NPK). The factorial experiment was mounted on randomized complete block design and replicated three times. Ridged bed type + the highest level of fertilizer applied (60, 60, 80 kg/ha N-P 2 0 5 -K 2 0) + Fulan application interacted positively (P < 0.05) resulting in significant yields (32 and 30%) over the control treatments in mound and ridged bed types, respectively. The same treatment resulted in the highest marketable weight of yam which was 61% over ridged bed type + fertilizer applied at 60, 60, 80 kg/ha N-P 2 0 5 -K 2 0 without Fulan application. Cracks were significantly low in Fulan treated tubers. The outstanding reduction in cracks was recorded in mound + F4 + Fulan which were 92% less than mound bed type only (control) tubers. Additionally, Fulan application suppressed nematode densities. The remarkable suppression in Meloidogyne incognita and Pratylenchus coffeae occurred in ridged bed type + fertilizer applied at 45, 45, 60 kg/ha N-P 2 0 5 -K 2 0 + Fulan treatment which was 93% over mound bed type without fertilizer and Fulan application and 97% over mound bed type + fertilizer applied at 60, 60, 80 kg/ha N-P 2 0 5 -K 2 0 without Fulan application, respectively. Ridged bed type appeared to be the better plant bed type alternative since the highest yield and nematode suppression were recorded in that option; besides, ridging presents drudgery saving intervention which farmers could exploit.

ABSTRAK Tumpang sari merupakan modifikasi pengaturan tanaman yang dapat memberikan peningkatan hasil secara nyata dengan investasi tenaga kerja minimal. Peningkatan produktivitas dalam tumpang sari kedelai dengan ubi kayu dapat dicapai melalui penggunaan genotipe kedelai yang sesuai untuk tumpang sari, dikarenakan setiap genotipe menunjukkan respons yang berbeda terhadap tumpang sari penelitian bertujuan mengidentifikasi kesesuaian genotipe kedelai untuk tumpang sari dengan ubi kayu berdasarkan hasil dan produktivitas lahan yang dinilai berdasarkan rasio kesetaraan lahan. Penelitian dilakukan pada tahun 2016 di Kebun Percobaan Kendalpayak, Malang, menggunakan rancangan petak terbagi diulang tiga kali. Petak utama adalah 55 genotipe kedelai (50 galur harapan dan 5 varietas pembanding, yaitu Argopuro, Panderman, Dena 1, Dena 2, dan Grobogan) dan anak petak adalah pola tanam, yaitu monokultur dan tumpang sari. Hasil penelitian menunjukkan bahwa tumpang sari kedelai dengan ubi kayu menyebabkan tanaman kedelai mengalami cekaman naungan, dengan tingkat naungan 6290, 4377, dan 040% masing-masing untuk posisi baris pertama, kedua, dan ketiga. Terdapat enam genotipe kedelai yang sesuai untuk ditumpangsarikan dengan ubi kayu, yaitu Grob/Argom313-2, Grob/Pander395-3, Grob/Pander405-3, Grob/Pander428-1, Grob/Pander429-2, dan Grob/IAC439-2 dengan nilai LER ≥1,8 yang merupakan batas seleksi 10% terhadap LER. Empat kombinasi diantaranya (Grob/Pander395-3, Grob/Pander405-3, Grob/Pander428-1, dan Grob/IAC439-2) memberikan peningkatan hasil ubi kayu antara 7,719,7% dan pengurangan hasil kedelai antara 21,438,5%. Sedangkan, dua kombinasi lainnya (Grob/Argom313-2 dan Grob/Pander429-2) memberikan pengurangan hasil ubi kayu sebesar 1,4 dan 8,5% serta pengurangan hasil kedelai sebesar 23,5 dan 7,1%. Kata kunci: hasil, kedelai, naungan, rasio kesetaraan lahan, ubi kayu
