“…CRISOSTO et al (1997) reported that N deficient peach trees produced small fruits. RADER et al (1985) pointed out that N fertilization resulted in an increase of peach size. Furthermore, ARORA et al (1999) concluded that fruit weight was associated with leaf N content.…”

The response of the peach cvs. Springtime and Redhaven to nitrogen, phosphorus, potassium fertilizers and manure is reported. The research was conducted during a period of 10 years. The following fertilizer combinations were used: control (no fertilization), N, P, K, NP, NK, PK, PK, manure, N + manure, P + manure, K + manure, NP + manure, NK + manure, <br />PK + manure, NPK + manure. The following measurements were performed: a) productivity (kg/tree); b) mean fruit weight (g); c) fruit number per tree; d) fruit setting (%); e) trunk circumference (cm), and f) shoot weight (kg) removed by pruning. It is concluded from the results that the two cvs. did not always respond to the various treatments in the same way. Application of N plus manure to peach trees of the cv. Springtime resulted in the highest productivity. The higher productivity of the cv. Redhaven was recorded in the treatments N and NPK. The lowest productivity, fruit number, total trunk circumference and shoot weight removed by pruning of both cvs. were recorded in the control and PK treatments in comparison with all the others. Fruit setting of the cv. Springtime was highest in the NP + manure treatment, followed by the PK + manure one. Fruit setting of the cv. Redhaven was higher in the PK + manure, NK + manure and K + manure treatments. Shoot weight that was removed by pruning was highest in the NK + manure treatment for the cv. Springtime, whereas for the cv. Redhaven it was highest in the N + manure treatment in comparison with the remaining ones.

Observations in controlled field experiments over 5 years indicated that imidacloprid, applied as a soil drench around the trunks of peach (Prunus persica), nectarine (P. persica var. nectarine) and japanese plum (P. salicinia) trees at planting and in the early spring and mid-summer for two subsequent seasons (0.7 g/tree a.i.), slowed the development of symptoms of phony peach disease (PPD) and plum leaf scald (PLS) (Xylella fastidiosa) in the trees. After 3.5 years, the percentage of peach trees showing PPD symptoms was 8.5% for the imidacloprid-treated trees compared to 34.3% for untreated trees. After 4.5 years, the percentage of peach trees showing PPD symptoms was 13.1% in the treated trees and 71.4% in the untreated trees. After 3.5 years, nectarine trees in untreated and treated plots showed PPD symptoms in 8.3% and 0.9% of the trees, respectively. After 4.5 years, PPD symptoms in nectarine were found in 32.3% of the untreated trees and 8.5% of the treated trees. Development of PLS disease in plum was also slowed by the trunk drench with imidacloprid in two japanese plum varieties. After 3.5 years, dieback was observed in 55% of the twigs of untreated and 23% of the twigs of treated trees of `Au Rosa' plum and 33% of the twigs of untreated and 12% of the twigs of treated trees of `Santa Rosa' plum.

“…Seaweed extract, being organic and biodegradable in nature is important in sustainable agriculture. The use of seaweed products in organic farming has widely increased (Rader et al, 1985). Its extract contains growth promoting hormones like auxins, gibberellins, cytokinins, ethylene and polyamines other than the trace elements, vitamins, amino acids, antibiotics and micronutrients.…”

The present investigation entitled “Effect of Growth Regulator (IBA) and Natural Substances the Root and Shoot Growth and Survival Percentage of Pomegranate Cuttings (Punica granatum. L)” was carried out during the year 2021-2022 at the Department of Horticulture, Sam Higginbottom University of Agricultural Technology & Sciences, Prayagraj. The experiment was laid out in Completely Randomized Design (CRD) with nine treatments and three replications. The treatment comprises; T1- Control (water), T2- IBA @1000 ppm, T3- IBA @750 ppm, T4- Vermiwash @100%, T5- Vermiwash @75%, T6- Seaweed extract @100%, T7- Seaweed extract @75%, T8- CPP (Cow Pat Pit) @100%, T9- CPP (Cow Pat Pit) @75%. On the basis of analysis of results, it is found that T4- vermiwash@100% proved best as a potential input for different parameters recorded such as days of first shoot initiation (11), average shoot length (35.78 cm), number of roots per cuttings (38.22), number of leaves per plant (83.89), average root length per cuttings (25.55cm), average leaf area (7.01cm2 ), fresh weight of roots (7.36g), dry weight of roots (3.78g), average shoot girth (3.31cm), average shoot fresh weight (18.89g), average shoot dry weight (9.89g) and survival percentage of pomegranate cuttings in the field after transplanting (93.75%).
