Field experiments were conducted at Tamil Nadu Agricultural University, Coimbatore, during 1994–1996 covering two kharif (June-September) and two summer (January–April) seasons in soybean, to evaluate the combined effect of organic manures and inorganic fertiliser with different weed management practices on the growth and yield of soybean. The results revealed that the joint application of bio-digested slurry at a rate of 5.0 t ha –1 + 30:120:40 kg NPK ha –1 distinctly increased the plant height, leaf area index (LAI), dry matter production (DMP) and yield of soybean. Hand weeding twice (20 and 40 days after sowing) considerably increased the plant height, LAI, DMP and yield of soybean, followed by alachlor 1.0 kg ha –1 + hand weeding at 40 DAS in all the seasons.

Background: To study effect of various spacing and weed management practices on weed control, growth parameter, yield and yield attributes of pigeon pea variety Pusa Arhar-16, field experiments were conducted at Student’s Research Farm, Khalsa College Amritsar, Punjab, India during kharif season of 2019-20.Methods: The experiment was laid out in Split plot design with three replications. The treatments comprised of four different spacing i.e. S1 (30×10 cm), S2 (30×15 cm), S3 (40×15 cm) and S4 (50×25 cm) which were considered as main plot treatments and three weed management practices W1 (weedy check), W2 (pendimethalin @ 1.5 kg a.i. ha-1 at 1DAS) and W3 (rice straw mulch) as sub-plot treatments.Result: It was found that maximum plant height (218.2 cm) and highest leaf area index (2.104) was recorded in treatment S1 (30×10 cm) whereas treatment S4 (50×25 cm) was superior in rest of growth parameters viz. maximum crop growth rate (0.85 gram per plant per day), number of primary branches (18.2 per plant) and number of secondary branches (13.8 per plant). Among yield and yield attributes, spacing S1 (30×10 cm) showed maximum grain yield (16.29 q ha-1) and stover yield (49.29 q ha-1) whereas, maximum number of pods per plant (154.6), pod length (4.83 cm), number of seeds per pod (3.90) and 100-seed weight (7.14 grams) were recorded in spacing S4 (50×25 cm). The weed management treatments showed non-significant effect on growth and yield parameters due to weed suppressing ability of the crop. which might be due to weed suppressing ability of the crop. It may be concluded that pigeon pea cultivar Pusa Arhar-16 performed better in narrower spacing of 30×10 cm due to its dwarf nature and it also showed good smothering effect on the weeds due to its smothering effect.

Field experiments were conducted at the Agricultural College and Research Institute, Tamil Nadu Agricultural University, Killikulam, India during the kharif (July to November) and summer (December to April) seasons of 1999 and 2000 in a randomized block design. The treatment consisted of three pre-emergence herbicides (pretilachlor + safener 0.3 kg ha-1 4 days after sowing [DAS], butachlor 1.0 kg ha-1 8 DAS and pendimethalin 1.0 kg ha-1 8 DAS) and one early post-emergence herbicide (butanil 3.0 ha-1 15 DAS), each in combination with mechanical or hand weeding 30 and 45 DAS. In addition, green manure (Daincha) intercropping and incorporation, mechanical and hand weeding twice alone (25 and 50 DAS) were compared with the unweeded check. The results revealed that the pre-emergence application of pretilachlor + safener 0.3 kg ha-1 + hand weeding twice (30 and 45 DAS) promoted higher yield attributes and maximum yield in wet-seeded rice.

This research was conducted to investigate the effect of different herbicides with weed management practices on growth and yield performance of mungbean genotypes. The experiment consisted of two factors were mungbean genotypes and weed management. There were two genotypes namely BARI Mung 6 and BARI Mung 8. While there were five weed management practices namely control/no weeding and without herbicide application (T1), hand weeding at 20 and 40 DAS (T2), pre emergence herbicide (Panida) at 1-2 DAS (T3), pre emergence herbicide (Neon) at 2-3 DAS (T4), and post emergence herbicide (Neon) at 10-15 DAS+hand weeding (T5). The results revealed that BARI Mung 6 stand superior to BARI Mung 8 in respect of dry matter content/plant, pods/plant, seeds/plant, seed yield, and 1000 seed weight. Among weed management practices, maximum plant height (53.70 cm), dry matter weight/plant (17.96 g), pods/plant (18.31), seeds/plant (171.47), maximum weed control efficiency (33.78 %) obtained from T3 treatment. Based on the interaction effect showed that BARI Mung 6 weeded with pre emergence herbicide (Panida) at 1-2 DAS produced maximum seed yield (1.79 t/ha) as well as yield attributes showed 2.29 % higher seed yield.

Field experiments were conducted at the Agricultural Research Station, Aliyar Nagar, Tamil Nadu, India during summer 1994 and 1995 on groundnut, adopting a split plot design. Two irrigation regimes based on Irrigation Water/Cumulative Pan Evaporation (IW/CPE) ratios of 0.60 (I1) and 0.75 (I2) were allotted to the main plot. Twelve treatments involving combinations of organic manure with mineral fertilizer were assigned to the subplots. Irrigation scheduled at IW/CPE 0.75 led to higher plant height, number of branches plant –1, dry matter production and leaf area index, resulting in higher yield than IW/CPE 0.60. All the growth attributes and the yield increased in response to a higher level of mineral fertilizer application and organic manure application. The combined application of inorganic and organic manures significantly enhanced the growth attributes and yield of groundnut compared to the sole application of either of them.

A study was initiated in Instruction-cum-Research Farm of Assam Agricultural University, Jorhat-13, Assam, India during 2014-15 and 2015-16. The objective of this experiment is to understand the impact of legume intercropping system in combination with different weed management practices on the growth indices of ginger crop. Nadia, a commercially grown variety of ginger in Assam was examined in the current study. A total of 16 treatment combinations were considered which comprised of 4 intercropping systems along with 4 weed management practices. Amongst the legume intercropping, Cowpea in between rows of Ginger; incorporated at 40 days after sowing (DAS) and Cowpea in alternate rows of Ginger; incorporated at 40 DAS recorded better results in terms of Leaf area index (LAI), Crop growth rate (CGR), Absolute growth rate (AGR) and yield of Nadia variety ginger. Whereas amongst the weed management practices, pre-emergence application of Metribuzin 500 g ai ha-1 + hand weeding (HW) at 70, 100 and 140 days after planting (DAP) scored higher in growth indices and ginger yield, but neither the legume intercropping systems nor the weed management treatments had any significant impact on harvest index.

A field experiment was conducted during kharif, 2016 and 2017 at S.V. Agricultural College farm, Tirupati to study the influence of spacing, nutrient and weed nutrient management practices on growth and yield of foxtail millet. Significant effects were noticed on growth and yield components viz., plant height, number of panicles m-2, weight of the panicle, grain weight panicle-1, grain and straw yield of foxtail millet. Among different plant geometries tried, closer spacing of 20 cm x10 cm registered taller plants, higher number of panicles m-2, higher grain and straw yield, where as the weight of the panicle, grain weight panicle-1 were found to be highest with 30 cm x10 cm. Among the micronutrient management practices, foliar application of ZnSO4@ 0.5% twice at the time of flowering and at grain filling stage along with 100% RDF registered taller plants as well as higher grain yields.Hand weeding at 20 DAS and 30 DAS outperformed other weed management practices. This was followed by pre-emergence application of butachlor @ 1 kg a.i ha-1 with one hand weeding at 30DAS.The study concluded that the closer spacing of 20cmx 10cm, foliar application of ZnSO4 at the time of flowering and 20 days after flowering along with RDF and hand weeding twice at 20 DAS and 30 DAS resulted in higher productivity of foxtail millet.
