Yield Maximization

Pigeonpea is cultivated as a major source of protein for poor farmers with reduced yields. The low yield of pigeonpea is due to faulty agro techniques. The present investigation was conducted to see the effect of integrated agro-techniques on growth and growth attributes of pigeonpea and designed with block randomization having eight treatments viz., integrated nutrient management (INM), integrated weed management (IWM), integrated pest management (IPM) and its combos at AICRP experimental farm, College of Agriculture Tripura. Growth and yield attributes differed significantly due to integrated agro-techniques with poor weed population in IWM. The net come was highest in INM+IWM+IPM (Rs. 49243.85 and Rs. 47757.63). Results revealed that INM+IWM+IPM yielded higher followed by INM+IWM however each of them was statistically at par throughout the study. Economics led INM+IWM as best treatment than the combination of 3 agro-techniques, where additional price occurred.

Weeds are serious problem in dry direct seeded rice (DDSR). A field experiment was conducted during rainy seasons of 2010 and 2011 at research farm of the Regional Agricultural Research Station (RARS) Parwanipur, to study the effect of integrated weed management practices on the performance of dry direct seeded rice. Ten treatment combinations viz; weedy, weed free (weekly), Pendimethalin fb (followed by) Bispyribac, Pendimethalin fb two hand weeding, Stale seedbed fb Bispyribac, Stale seedbed fb Pendimethalin fb Bispyribac, Mulch 4 t/ha fb Bispyribac fb one hand weeding, Stale seedbed fb mulch 4 t/ha fb Bispyribac, Pendimethalin and Sesbania co-culture fb 2,4-D Na salt fb one hand weeding and Pendimethalin fb 2,4-D fb one hand weeding were tested in a randomized complete block design and replicated thrice. Observations were taken on weed, plant growth and yield attributes, yield, and socio-economic parameters. All weed control treatments significantly reduced the weed density and dry weight of weed resulting significant increase in yield of DSR over weedy check in both years. Weed free treatment resulted the highest yield, however, it was not economical due to high cost of cultivation. The use of Pendimethalin fb 2,4-D fb one hand weeding produced yield (5161 in 2010 and 6160 kg/ha in 2011) which were statistically at par with yield (5305 in 2010 and 6319 kg/ha in 2011) obtained under the weed free treatment. Further, the highest benefit cost ratio (CBR) 1.77 and 2.22 and net return Rs 47700 and 75084/ha during 2010 and 2011, respectively, were obtained under this treatment indicating its superiority over other treatments. The grain yield, yield attributing characters viz. panicles per m2, panicle weight, filled grain per panicle, thousand grain weight as influenced by different weed management practices revealed that higher yield resulted from weed free plot followed by Pendimethalin followed by two hand weeding and Pendimethalin followed by 2,4-D followed by one hand weeding. However, the net return per unit investment resulted highest in Pendimethalin followed by 2,4-D followed by one hand weeding. This proved that amid increasing wage rate and labor scarcity integrated weed management through Pendimethalin 30 EC (stomp) @ 1 kg a. i./ha as pre- emergence herbicide application followed by 2,4-D sodium salt 80 WP @ 0.5 kg a.i./ha followed by one hand weeding or stale seed bed followed by Pendimethalin 30 EC (stomp) @ 1 kg a. i./ha followed by Bispyribac (nominee gold) @ 25 g a. i./ha 10 % @ 200 ml/ha at 20 days of seeding resulted best alternative for manual hand weeding practices giving higher net return per unit investment.

A field experiment entitled, “Integrated weed management in Kharif maize (Zea mays L.)” was conducted during Kharif, 2020 at Post Graduate Research Farm, RCSM College of Agriculture, Kolhapur. The experiment was laid out in Randomized Block Design (RBD) having three replications and twelve treatments. The soil of the experimental plot was medium black clay (vertisol) with 90 cm depth, low in available N (250 kg ha-1), high in available P2O5 (30.60 kg ha-1) and medium in available K2O (290.67 kg ha- 1). The status of organic carbon content (0.34%) was low. The electrical conductivity and pH values were 4.2 dSm-1 and 7.10, respectively.Weed free check and tank mixure application of Tembotrinone 42 SC @ 120gm a.i.ha-1 + Atrazine 50 WP @ 500 gm a.i.ha-1 + surfactant @ 2ml/l of water EPoE At 20-25 DAS + fb hand weeding at 40 DAS were on par with each other and recorded significantly the higher growth and yield contributing characters viz., plant height (cm), number of functional leaves plant-1, leaf area plant-1(dm2), dry matter plant-1(g), length of cob (cm), diameter of cob(cm), number of grains, weight of grains cob-1and test weight resulting into significant increase in grain and straw yields of maize as compared to remaining weed management treatments. Tank mixure application of Tembotrinone 42 SC @ 120gm a.i.ha-1 + Atrazine 50 WP @ 500 gm a.i.ha-1 + surfactant @ 2ml/l of water EPoE At 20-25 DAS + fb hand weeding at 40 DAS recorded minimum dry weight of weed, highest weed control efficiency (86.94 %) and lowest weed index (1.79%).Significantly lowest values for growth, yield and yield attributes as well as weed control efficiency was observed in weedy check treatment.

A field experiment was carried out at College Orchard, Department of Vegetable Crops, Horticultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore during 2014 to 2017 to investigate integrated weed management on growth, yield and economics in okra (Abelmoschus esculentus (L.) Moench) cv. COBhH 1 during kharif seasons. The experiment was laid out in Randomized Block Design (RBD) with seven treatments and replicated three times. The growth and yield attributes viz., plant height, number of fruits per plant, fruit yield per plant, fruit length, fruit girth, fruit yield kg per plot and fruit yield (q/ha) differed significantly due to different treatments. Growth and yield attributes increased significantly in weed free check (T2 ) which led to appropriate timing of weeding which reduced the influence of weed interference and increased the yield in okra. The results revealed that weed free check (T2 ) recorded the higher plant height (151.80 cm), number of fruits/plant (27.30) with an average fruit yield of 0.501 g per plant, fruit length (13.53 cm), fruit girth (7.53 cm), fruit yield (233.9 q/ha) and low weed density (12.03/m2 ) at 60 days after sowing. Whereas, the high cost benefit ratio (2.88) was recorded in pre emergence of pendimethalin @ 1.0 kg/ha + one hand weeding (T4 ) which also recorded 23.36 number of fruits/plant with fruit yield of 223.0 q/ha. It is therefore recommended that pre emergence application of pendimethalin @ 1.0 kg/ha + one hand weeding will be optimal for okra production in kharif season.

Red gram [Cajanus cajan (L.) Millsp.] is a new introduction in the southern laterites of Kerala. The field experiment was laid out in factorial RBD to assess the performance of the short duration varieties of red gram, APK 1 and Vamban (Rg) 3 under two spacings (40 cm x 20 cm and 60 cm x 30 cm) and three nutrient levels (40:80:40, 30:60:30 and 20:40:20 kg NPK ha-1) in the Instructional Farm, College of Agriculture, Vellayani, Kerala during November 2018 to March 2019. Significant variations were recorded in growth and yield attributes and among the varieties, APK 1 was found to be superior with a seed yield of 997.78 kg ha-1. The closer spacing of 40 cm x 20 cm and the highest dose of 40:80:40 kg NPK ha-1 recorded the significantly highest seed yields of 1195.00 kg ha-1 and 1055.83 kg ha-1, respectively. The three factor interaction also revealed APK 1 and Vamban (Rg) 3 to record superior seed yields at the closer spacing and higher nutrient dose. The short stature, lower branching tendency, early flowering nature and higher yields in APK 1, proved its suitability for cultivation in southern laterites of Kerala and the agronomic package would involve sowing seeds at a spacing of 40 cm x 20 cm with an NPK dose of 40:80:40 kg ha-1.

A field trial was conducted during two consecutive summer seasons of2012 and 2013 at ICAR-Central Potato Research Station, Shillong, Meghalaya to evaluate the integration of nutrient sources on productivity and soil health under rainfed potato cultivation in north eastern hill region of India. There were six treatments of integrated nutrient management viz., 100% Recommended dose of fertilizers,75% RDF through synthetic fertilizers and 25% recommended dose of nitrogen (RDN) through FYM, 50% RDF and 50% RDN through FYM, 25% RDF and 75% RDN through FYM, 100% RDN through FYM and control (no application of any sources of nutrients). The experiment was laid out in randomized block design with four replications. Nutrient management practices showed the significant improvement on growth and yield attributes of potato over control plot. Highest productivity of potato tubers (t/ha) was noticed with application of 75% RDF through synthetic fertilizers along with 25% RDN through FYM. Similarly, the maximum net return was associated with application of 75% RDF and 25% RDN through FYM under investigation. Application of 75% Recommended dose of nutrients through synthetic fertilizers in combination with 25% Recommended dose of nitrogen through FYM was more profitable for sustainable production of potato in the north eastern hill region of India.
