Studies on growth and yield indicators for kohlrabi (Brassica oleracea) plant treated with mineral fertilizers and root enhancers

The research was conducted at Beltari Sandhikharka-10, Arghakhanchi district to study about the effect of various doses of boron on growth and yield attributing characters of cauliflower (Brassica oleracea var. botrytis) during off-season from February to June in 2020. Five treatments; B0 (control/no application), B1: 2kg/ha, B2: 4kg/ha, B3: 6kg/ha, B4: 8kg/ha which are the different doses of boron application were laid out in Randomized Complete Block Design (RCBD) with 4 replications. The growth parameters like plant height, number of leaves per plant leaf length and leaf breadth of largest leaf were recorded multiple times with 15 days interval. Days to curd initiation and Days from curd initiation to harvest were recorded by regular field observation. The yield parameters; curd weight with leaves, Marketable curd weight, average curd yield, incidence of hollowing were recorded during harvest. The economics from application of boron doses in cauliflower production was obtained in terms of cost of cultivation, gross returns, net returns, and benefit cost ratio. The result showed that the growth and yield attributing characters of cauliflower were significantly affected by application of boron in which the value of these parameters was found significantly higher in B1 followed by other treatments. The average curd yield of cauliflower in B1 was found to be 12.39 mt/ha which was 48.92% higher than that of B0 with curd yield 8.32 mt/ha. Similarly, the net return was found significantly the highest in B1 and the lowest in B0. The result showed that application of boron in the range of 2-4 kg/ha is preferred to control and higher doses in respect of both productivity and economics.

Field experiments were conducted in 1987 and 1988 to study the effect of lamb’s-quarters (Chenopodium album L.) interference on broccoli (Brassica oleracea L. var. botrytis ’Emperor’) growth and yield. Broccoli growth was initially affected by weed interference at 28–36 d after seeding. Generally, the negative effect of weed interference on broccoli growth increased with increasing weed density and time after seeding. Interference by 15 lamb’s-quarters plants m−2 reduced the biomass of broccoli plants by 71–73% compared to the weed-free control at 57–58 d after seeding. Weed density-crop yield relationship curves showed that one lamb’s-quarters plant m−2 decreased total yield by 18–20% and marketable yield by 22–37%. Lamb’s-quarters reduced the total yield per plot by decreasing the average head weight of broccoli. The number of heads per plot was not affected. Weed interference also reduced the weight of heads classified as marketable (> 10 cm across). However, in 1987 more heads failed to reach a marketable size which resulted in a much smaller marketable yield than in 1988.Key words: Brassica oleracea var. botrytis, broccoli, Chenopodium album L., weed density, weed interference, cole crop

AbstractA field experiment was carried out to investigate the effect of different manures and fertilizers on the growth and yield of knol-khol (Brassica oleracea var. gongylodes) at Dr. Purnendu Gain Field Laboratory of Agrotechnology Discipline, Khulna University, Khulna from November 2014 to February 2015. The single factor experiment comprised of different types of fertilizers and manures viz., T0 (Control), T1 (Recommended doses of NPK), T2 (Cow dung), T3 (Vermicompost), T4 (Poultry manure), T5 (50 % Cow dung + 50 % NPK), T6 (50% Vermicompost + 50% Cow dung), T7 (50% Vermicompost + 50 % Poultry manure) and T8 (25% Cow dung+ 25% Vermicompost+ 25% Poultry manure + 25% NPK). The Experiment was laid out in Randomized Complete Block Design (RCBD) with four replications. The maximum plant height was obtained from the treatment T1 at 25, 35 and 45 Days after transplanting (DAT). The maximum spread of canopy was 36.75 cm, 52.50 cm and 66.05 cm from the treatment T3, T7 and T2, respectively. The maximum economic yield (21.92 t/ha) and biological yield (40.083 t/ha) were found in the treatment T1 and T7, respectively. Highest benefit cost ratio (3.07) was obtained from the treatment T1whilethe minimum (0.57) was obtained from T3 which indicates that high cost of vermicompost affect net return severely. Although, T1 produced maximum benefit cost ratio, the treatment T4 and T2 are very close to T1 and also statistically similar. So, we can consider poultry manure and cow dung for our soil health, environmental benefits and ecological safety.

The Cauliflower (Brassica oleracea L.) PM 126 F1 is one of the vegetable commodities with a high enough demand because this vegetable is widely consumed by the public. This experiment purposes to get a dose combination of oyster mushroom waste organic fertilizer and NPK fertilizer which gives the highest growth and yield of cauliflower. The method of research used is the experimental method. The design of experimental used was randomize block design (RBD) with a single factor that consisted of 8 treatments with 3 replications, that is : A (control), B (10 ton/ha Organic fertilizer), C (20 ton/ha Organic fertilizer), D (30 ton/ha Organic fertilizer), E (NPK 800 kg/ha), F (10 ton/ha Organic fertilizer + NPK 800 kg/ha), G (20 ton/ha Organic fertilizer + NPK 800 kg/ha), H (30 ton/ha Organic fertilizer + NPK 800 kg/ha). the result highest curd weight is 7,75 ton/ha achieved by treatment G is 20 ton/ha waste compost of oyster mushroom and 800 kg/ha NPK fertilizer.

Organic Fertiliser

Farmers use Inorganic Fertilizers (IF) to improve kenaf yield in Nigeria. However, the detrimental effects of mineral fertilizers and its high cost calls for the use of organic fertilizers that are locally available and environment friendly. Combination of Organic Fertiliser (OF) with IF may reduce the bulkiness of OF while harnessing the benefit of both for higher yields. Field trials were conducted at Ibadan and Ilora in 2013 and 2014 to investigate the effects of combined fertilizers on the growth and yield of kenaf. Organic and IF (NPK 20:10:10) fertilizers as: (i) 160 kg ha-1 (sole organic), (ii) 100 kg ha-1 (sole IFl), (iii) Organic and IF at 50:50 ratio and (iv) control (no fertilizer). The experiment was laid out in Randomized Complete block design (RCBD) and replicated three times. Results showed that plant height (220.17 cm, 216.80 cm) and stem diameter (2.27 cm, 1.16 cm). Bast fiber (2.27 t/ha, 2.27 t/ha) and seed yield (1.69 t/ha, 1.78 t/ha) in Ibadan and Ilora respectively were significantly higher in plots with combined fertilizer. Combined fertilizers had the highest fiber and seed yield above sole application and control (no fertilizer application). Hence it is recommended for kenaf cultivation in Southwest Nigeria.

Net Assimilation

Two field experiments were conducted in two successive seasons, 2005/2006 and 2006/2007, to determine whether management can improve faba bean competitiveness with weeds, thus helping to achieve its yield potential. The experiment included five treatments, composed of organic and mineral fertilizers, alone and mixed at different rates, along with a control and six weed control treatments, including oxadiargyl, prometryn, hand hoeing treatments alone or mixed with the herbicides, and a nonweeded treatment (control).The herbicide treatments were not superior to the two hand-hoeing treatments. Using compost favored growth and yield of faba bean more than of weeds. Adding fertilizer also improved most yield parameters. Application of compost alone or combined with 50 or 100% of the recommended NPK rate improved faba bean growth in terms of net assimilation rate, specific leaf area, and leaf weight ratio as components of relative growth rate. This improvement in growth resulted in increase of seed yield, yield components and protein of faba bean. Faba bean yield performance improved under interactive fertilizer effects and weed control treatments as growth improved, as a result of nutrient release from fertilizers and weed control.
