Guava ( Psidium Guajava )+Summer Groundnut ( Arachis Hypogea ) for Control of Biotic and Abiotic Harmful Factors R. A. Singh α , I. P. Singh σ , V. R. Chaudhary ρ , R. K. Singh Ѡ & Dharmendra Yadav ¥ Abstract- The field study was laid out during three consecutive years of 2005-06 to 2007-08 at Mainpuri, Farrukhabad and Kannauj districts. The operational area located between catchments area of Ganga and Kali rivers. The experimental soils were loamy sand, sandy loam and light loam in texture. The analysis of composite soil sample displayed low status of plant nutrients. The four treatments i.e, guava + groundnut cv. Dh-86 + soil application of neem leaves power @ 50 kg/ha and spraying of neem oil on guava plants @ 2.5 lit/ha, guava + groundnut cv. Dh-86 + soil application of neem leaves powder @ 100 kg/ha and spraying of neem oil on guava plants @ 2.5 lit/ha, guava + groundnut cv ICGV 93468 + soil application of neem leaves powder @ 50 kg/ha and spraying of neem oil on guava plants @ 2.5 lit/ha and guava + groundnut cv. ICGV-93468 + soil application of neem leaves powder @ 100 kg/ha and spraying of neem oil on guava plants @ 2.5 lit/ha were tested. The farmers were suggested for plantation of guava at the spacing of 6x6 m 2 . The cultivars Dh-86 and ICGV-93468 (Avtar) were selected and planted between 5-10 March of experimental years. The 20 rows of groundnut were planted between two rows guava. The sowing of groundnut was made at spacing of 25 cm in rows. The gap of 50 cm from the both side was maintained between adjacent of guava and groundnut to facilitate easy intercultural practices. The guava + groundnut cv. ICGV-93468 + soil application of neem leaves powder @ 100 kg/ha and spraying of neem oil on guava plants @ 2.5 lit/ha treatment gave highest fruits yield of guava by 79.00 q/ha and pods yields of summer groundnut as 31.00 q/ha. The highest system productivity was found under guava + groundnut cv. ICGV- 93468 + soil application of neem leaves powder @ 100 kg/ha and spraying of neem oil @ 2.5 lit/ha by 110.00 q/ha, closely followed by guava + groundnut cv. Dh-86 + soil application of neem leaves powder @ 100 kg/ha and spraying of neem oil on guava plants @ 2.5 lit/ha (106.30 q/ha). The incidence of white grubs and BND were found absent but termites and pod borers damage the groundnut pods 1-2% only. Keywords: BND, Dh-86, ICGV-93468, summer groundnut, white grubs. I. I ntroduction n Uttar Pradesh (India), the riverine soils of Semi-Arid- Tropics (SAT) area, having loamy sand, sandy loam and light loam texture is famous for cultivation of groundnut in rainy season. In early 1980s, groundnut was grown in U.P. on an area of 0.3 million ha with production of 0.19 million t. Since then, both area and production have slowly and steadily decreased due to various reason especially white grubs and other soil insect and by 2010-11 the groundnut area reduced to 0.08 million ha and the production to 0.08 million tonnes with an average productivity of 988 kg/ha and the area under rainy season groundnut was gradually occupied largely by guava and other horticultural and field crops. With the introduction and spread of groundnut cultivars Dh-86 and ICGV-93468 (Avtar) for cultivation in summer. The area under summer groundnut grew in leaps and bounds from non in 2001 to 3,17,068 ha in 2011 with productivity of 25.32 q/ha. This rapid growth of area under summer groundnut promoted the need for research on cultivation of groundnut in area occupied by guava. The main objective of the experiment was to explore the feasibility of summer groundnut cultivation in the interspaces of younger plantation or already planted guava for utilizing the vacant spaces along with control of insects especially soil insects, which are damage to the pods of groundnut. The secondary objective was to increase the area under summer groundnut in catchments area of river Ganga and its tributaries , where, guava orchards have been well established. The experiment was planed on sandy loam, sandy clay loam and light loam soil of Semi-Arid Climatic Zone of Uttar Pradesh for cultivation summer groundnut during March to June by utilizing the area available between the widely spaced rows of guava. Therefore, filler cropping of summer groundnut in guava spaces is the subject matter of this manuscript. II. M aterials and M ethods The innovative field study was undertaken during three consecutive years of 2005-06 to 2007-08 at Mainpuri, Farrukhabad and Kannuaj districts. The operational area located between the catchments area of rivers Ganga and Kali . The soils of operational area were loamy sand, sandy loam and light loam in texture. The composite sample of soil was taken and analyzed. The composite soil sample, having pH 7.9, organic carbon 0.27%, total nitrogen 0.03%, available P 2 O 5 7.9 kg/ha and available K 2 O 192 kg/ha. The pH was determined by Electrometric glass electrode method (Piper, 1950), while organic carbon was determined by I 1 Year 2023 1 © 2023 Global Journals Global Journal of Science Frontier Research Volume XXIII Issue ersion I VI ( D ) Author α σ ρ ¥ : C.S.
